I have created an ubuntu image with nginx, php and postgres.
I want to connect the postgres database in my current image with pgadmin located on my local machine.
I have tried using docker inspector to try to use the image ip to make a connection with my local pgadmin but without much success. I've also tried configuring some ports on local to make connection work.
It's a valid question don't know why people feel "doesn't seem possible to answer that question".
So, here's how I do what you are trying to do:
Pull postgres image from Docker Hub
docker pull postgres:latest
Run the container using the below command
docker run -p 5432:5432 postgres
Using docker's inspect command find the IP
Use that IP, PORT, Username, and Password to connect in PGADMIN
You can also do a simple telnet like below to confirm if you can access docker postgres container:
telnet IP_ADDRESS 5432
1. Postgres with Docker
docker run \
-p 5432:5432 \
--name container-postgresdb \
-e POSTGRES_PASSWORD=admin \
-d postgres
2. PgAdmin with Docker
docker run \
-p 5050:80 \
-e "PGADMIN_DEFAULT_EMAIL=name#example.com" \
-e "PGADMIN_DEFAULT_PASSWORD=admin" \
-d dpage/pgadmin4
3. Connection string for PgAdmin
Enter PgAdmin on localhost:80. Then add a server with:
name: container-postgresdb
host: host.docker.internal
database: postgres
user: postgres
password: admin
You can also use this to find out the host address — it will be listed as IPAddress in the output —:
docker inspect container-postgresdb \
-f "{{json .NetworkSettings.Networks }}"

What I have done success on windows 10 running docker for windows 1.12.6(9655), the step is like below:
Pull the latest postgres
docker pull postgres:latest
run the postgres containner:
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name db-my -p 5432:5432 --restart=always postgres
Then installed the latest version of pgAdmin4 from
pgadmin website
Run pgAdmin 4 create new server, and input as following
Host: 127.0.0.1
Port: 5432
User name: user
password: password123
Then everything is ok, connect to docker postgres instance success.
Alternatively, you could combine Postgres and Pgadmin in one docker-compose file, and login as user pgadmin4#pgadmin.org, pwd: admin. To add the Posgres server, use hostname postgres, port 5432.
version: '3'
services:
postgres:
image: postgres
hostname: postgres
ports:
- "6543:5432"
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: TEST_SM
volumes:
- postgres-data:/var/lib/postgresql/data
restart: unless-stopped
pgadmin:
image: dpage/pgadmin4
depends_on:
- postgres
ports:
- "5555:80"
environment:
PGADMIN_DEFAULT_EMAIL: pgadmin4#pgadmin.org
PGADMIN_DEFAULT_PASSWORD: admin
restart: unless-stopped
volumes:
postgres-data:
If you verified that PostgreSQL is running and you can connect there with local copy of PgAdmin...
The answer is simple: use host.docker.internal istead of localhost for the PgAdmin running inside the Docker
In my case I could solve the problem inspecting my postgre image through command
docker inspect CONTAINER_ID | grep IPAddress.
So, I used the docker ip address to config my pgadmin 4 connection and everything was fine. Thanks to #Afshin Ghazi
I included this in the docker yaml file to get the database and pgAdmin:
database:
image: postgres:10.4-alpine
container_name: kafka-nodejs-example-database
environment:
POSTGRES_USER: ${POSTGRES_USER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
expose:
- "5432"
ports:
- 8000:5432
volumes:
- ./services/database/schema.sql:/docker-entrypoint-initdb.d/1-schema.sql
- ./services/database/seed.sql:/docker-entrypoint-initdb.d/2-seed.sql
pgadmin:
image: dpage/pgadmin4
ports:
- 5454:5454/tcp
environment:
- PGADMIN_DEFAULT_EMAIL=admin#mydomain.com
- PGADMIN_DEFAULT_PASSWORD=postgres
- PGADMIN_LISTEN_PORT=5454
The postgres username is alphaone and the password is xxxxxxxxxxx.
Do a docker ps to get the container id and then docker inspect <dockerContainerId> | grep IPAddress
eg: docker inspect 2f50fabe8a87 | grep IPAddress
Insert the Ip address into pgAdmin and the database credentials used in docker:
If pgAdmin is intended to be run wihtin same Ubuntu host/guest, then you need to link postgres container, so it could be resolved by a name.
1. Run a postgres container:
docker run --name some-postgres -e POSTGRES_PASSWORD=postgres -d postgres
2. Run pgAdmin container:
docker run -p 80:80 --link some-postgres -e "PGADMIN_DEFAULT_EMAIL=email#domain.com" -e "PGADMIN_DEFAULT_PASSWORD=postgres" -d dpage/pgadmin4
3. Now when adding new server in phAdmin web app, use some-postgres as server name
Note the --link some-postgres when we were bringing up the pgAdmin. This command makes postgres container visible to pgAdmin container.
After facing this issue for two days i was able to resolve that issue.
solution of this problem is already answered by peoples like do inspect
docker inspect CONTAINER_ID
but while running this command i got a-lot of logs like Host Config Config Network Settings etc. so i got confused which IPAddress to add in the pgAdmin connection because i tried 0.0.0.0 and config, host, networkSettings different -2 IPAddress in the logs but finally it works after trying a-lot.
it works with which IP, we have to add that network ip address (which we created to connect the postgres and pgAdmin.)
like in my case when i run :-
docker inspect postgres_container
"NetworkSettings": {
"Bridge": "",

"Gateway": "192.168.16.1",
"IPAddress": "192.168.16.2",
"IPPrefixLen": 20,
"IPv6Gateway": "",
so we have to add the NetworkSettings -> Network -> Postgres(mine created network) -> IPAddress i.e. "IPAddress": "192.168.16.2".
After adding this ip it will work.
I hope it will help.
This worked for me on Ubuntu 18:
1- Run a postgres container
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name my-postgres -p 5432:5432 postgres
2- Run a pgAdmin container
docker run --rm -p 5050:5050 thajeztah/pgadmin4
3- Get your local IP (in Ubuntu by ifconfig command)
4- Open localhost:5050 in your browser
5- Click on Servers >> Create >> Server...
6- In General tab, give it a name, for example: docker. In Connection tab, enter these fields:
Host name: The IP from 3
Username: user
Password: password123
7- Click on Save and now everything should work fine.
Note: If this didn't work, try "localhost" for the host name.
In order or find your IP of the container, use following command
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

If you're on a mac and localhost use below as credentials:

You have to expose the postgres port in the container to you local system. You do this by running your container like this:
docker run -p 5432:5432 <name/id of container>
when connecting with your GUI client or CLI make sure to use the ip-address not localhost even if your ip-address is the localhost ip-address.
docker ps would give you the ip address your postgres container is on.
In my case, I had a PostgreSQL container, so I didn't change my container or create a docker-compose approach, I needed pgadming after few months to had installed PostgreSQL, so this is my approach:
docker inspect my_container_id_postgreSQL
The network assigned to PostgreSQL was:
"Networks": {
"docker_default": {
"IPAddress": "172.18.0.2",
...
}
}
Ran my PGADMIN with --network command.
docker run -p 85:80 --network docker_default -e 'PGADMIN_DEFAULT_EMAIL=user#domain.com' -e 'PGADMIN_DEFAULT_PASSWORD=SuperSecret' -d dpage/pgadmin4
Insert the Ip address into pgAdmin and the database credentials used in docker.
I hope this can be useful for someone.
Regards.
You can create a Docker bridge network to do this too.
$ docker network create pgnet

Open http://localhost:8000/
Click Add New Server
Create - Server
Name: db
Hostname/address: pg
Username: postgres
Password: pg123
Save
The Hostname/address used above is the name of the Postgres container given by --name pg
When you start container you have network alias for it. Just use this alias in pgadmin UI.
Like if you have the following docker compose config:
version: "3.5"
services:
postgres:
container_name: postgres-14
image: postgres:14.1
restart: unless-stopped
ports:
- "5432:5432"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- POSTGRES_PASSWORD=root
- POSTGRES_USER=postgres
hostname: postgres
pgadmin:
container_name: pgadmin4
image: dpage/pgadmin4
restart: unless-stopped
ports:
- "80:80"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- PGADMIN_DEFAULT_EMAIL=user#domain.com
- PGADMIN_DEFAULT_PASSWORD=admin
hostname: pgadmin
You can add server with hostname: postgres
For macOS IPs of postgres and pgadmin4 are different from the ones docker inspect provides.
Type
docker-machine ls
Take a look at the name of the server on the left. It's default by default.
docker-machine ip default will IP you need to use for both, pgadmin4 in browser and for postgres in pgadmin4 settings.
Are you using Window Subsystem LinuxWSL2 to run Docker and PgAdmin?
The steps I suggested is similar to what folks suggested. In my case I am using window environment
Step 1: Open CMD and type ipconfig and hit enter.
Step 2: Check WSL IPv4 Adress
Ethernet adapter vEthernet (WSL):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : 3bd9::997b:b52a::fe80::65b3%63
IPv4 Address. . . . . . . . . . . : 172.172.172.1 // use the IP as host/address
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Step 3: Open PgAdmin from the browse and create a server
Step 4:
// Here it depends on your desired config mine is the following
Server: postgres
host address: IPv4 Address(step 2)
username: postgress(username for postgress)
password: password(password for postgress)
I spend two days to figure out what was wrong, I hope someone will find it helpful
If local host port 5432 already in use by another psql servers, change it when creating the container and in Pgadmin.
What I have done success on macOS Monterrey running Docker Desktop for macOS(M1):
Pull the latest postgres:
docker pull postgres
Run the postgres container:
docker run -d -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres --name postgres-server -p 5432:5432 --restart=always postgres
Then installed the latest version of pgAdmin 4 (macOS) from pgadmin website
Run pgAdmin 4 create new server, and input as following Host: 127.0.0.1 Port: 5432 User name: postgres password: postgres
pgAdmin 4: Connection postgres-server
Here are the full steps that worked for me
Download and install pgadmin GUI tool
Run docker container: docker-compose up my-db.
From this command logs, note down ipv4 address and port. In my case, it's 0.0.0.0 and 5432.
Open docker-compose.yml file and note down POSTGRES PASSWORD
open pgadmin gui
enter name
In connection tab:
enter that ipv4 address in Hostname/address
enter that port
enter that POSTGRES PASSWORD in password
save. 🎊
To find the correct ip for your container, execute the following commands:
Check container ID:
docker ps
To check the correct IP of your container:
docker inspect <ID_CONTAINER> | grep "IPAddress"
The configuration of both PostgreSQL and PgAdmin with Docker are simple, if not right, I recommend redoing the configuration from scratch, if your problem is deeper.
Here is a script I developed to solve this problem.
script-sh/install-docker-postgres-and-pgadmin
I did not connect with my container pg (dpage/pgadmin4 image) from browser on 0.0.0.0:9090 .
I ran this command :
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' -d dpage/pgadmin4
Solution one :
First I tried to inspect the container for IP address
docker inspect pg
I got the container IP address "IPAddress": "172.17.0.3". http://172.17.0.3:9090 did not accessible.
Solution two :
And then I ran command without de-attached mode (-d removed)
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' dpage/pgadmin4
# Output, it should be running on 9090.
Listening at: http://[::]:80
-p 9090:9090 did not work.
Finally I found the solution :
On some filesystems that do not support extended attributes, it may
not be possible to run pgAdmin without specifying a value for
PGADMIN_LISTEN_PORT that is greater than 1024. In such cases, specify
an alternate port when launching the container by adding the
environment variable, for example:
-e 'PGADMIN_LISTEN_PORT=5050'
Don’t forget to adjust any host-container port mapping accordingly.
Read more about it official doc
I added -e 'PGADMIN_LISTEN_PORT=9090' and worked for me.
You can try both solutions, it will definitely work for you.
I ran this, It worked for me
docker pull dpage/pgadmin4
docker run -p 9000:80 -e 'PGADMIN_DEFAULT_EMAIL=test#gmail.com' -e 'PGADMIN_DEFAULT_PASSWORD=root' -d dpage/pgadmin4
The solution I tried and worked for me, was to create a docker compose file where I included postgress and pgadmin as services. For more details: Connecting pgadmin to postgres in docker
Tested on Mac
pgAdmin-4: version 6.12
I tried several answers here and in other places but nothing worked for me.
Here is the problem I had and the solution.
I had a docker postgres running my machine and need to connect this server in pgAdmin.
All I need to do was to check the docker information and fill the server configs based on that in pgAdmin.
You can do this by opening your docker and going to dashboard and then selecting the postgres image you're using. There is a tab called Inspect click on that. Here you can get all the information about that postgres container.
Now open the pgAdmin and resister a server by right clicking on the servers -> Register -> Server.
choose a name for the server and click Connection tab.
Here we need to fill the data like host name/address, IP, ports and etc.
In docker Inspect tab, there is Ports section that you can get this data from, something like this:
So your host address based on this picture is 172.0.0.1 and port is 5873.
Other info like database, user and password is also available in Environment section in docker Inspect tab.
Now fill the other information click save in pgAdmin and it should work.
Go to your container terminal on Docker Desktop and type hostname -I in case is linux to get the ip assigned to this machine, then go to your pgAdmin an try it out. #Rigoxls
I am trying to set up a circleCI test, I have created a database in circleCI and I have a docker container which needs to connect to the database, but it can't. Inside my docker container is a script which before it does anything it runs pg_isready, this cannot connect to the database. Here's my circle job creation
postgres_tests:
docker:
- image: circleci/python:3.7
- image: circleci/postgres:9.6.2-alpine
environment:
POSTGRES_USER: postgres
POSTGRES_DB: my_test
steps:
- setup_remote_docker:
docker_layer_caching: true
- attach_workspace:
at: /tmp/workspace
- run:
name: Install awscli docker-squash
working_directory: /
command: sudo pip3 install awscli docker-squash
- run: eval `aws ecr get-login --no-include-email --region eu-west-1`
- checkout
- run: echo 'export PATH=/usr/lib/postgresql/9.6/bin/:$PATH' >> $BASH_ENV
- run: sudo apt-get update && sudo apt-get install -y postgresql-client
- run: psql -h localhost -U postgres --command "ALTER USER postgres WITH PASSWORD 'password';"
- run:
name: run_pg_tests
working_directory: /tmp/workspace
command: |
/tmp/workspace/sql/t/run_tests.sh
The run_tests.sh is a script which pulls my docker image from the company repo and then does a docker run on that image.
I have read other people have issues where the database isn't ready so to test this I added pg_isready before the docker run
So my script looks like this
DB_HOST=`psql -X -A -h localhost -U postgres -p 5432 -t -c "select inet_server_addr()"`
DB_PORT=5432
DB_NAME=my_test
DB_USER=postgres
DB_PASSWORD=password
pg_isready -h "${DB_HOST}" -p "${DB_PORT}"
#restore database from supplied image
docker run \
-e SAPIENTIA_DB_HOST=$DB_HOST \
-e SAPIENTIA_DB_PORT=$DB_PORT \
-e SAPIENTIA_DB_NAME=$DB_NAME \
-e SAPIENTIA_DB_PASSWORD=$DB_PASSWORD \
-e SAPIENTIA_DB_USER=$DB_USER \
$EMPTY_DB_FULL_PATH \
path_to_file/file
I have also tried setting the DB_HOST variable directly to 'localhost' the result is exactly the same
Here's what I get as a result:
127.0.0.1:5432 - accepting connections
127.0.0.1:5432 - no response
I have also tried re-running the test with ssh and connecting myself. Same result, I can connect to the database, but i I then run docker exec and try to connect from inside the docker container it can't connect.
I'm pretty stumped here, so any help would be useful.
EDIT: I've found this documentation page about your issue:
It is not possible to start a service in remote docker and ping it directly from a primary container or to start a primary container that can ping a service in remote docker. To solve that, you’ll need to interact with a service from remote docker, as well as through the same container
That line is not 100% clear to me, but I understand that they tell us that we should run the containers we want to communicate from another container manually. Therefore:
- run:
name: run_pg_tests
working_directory: /tmp/workspace
command: |
docker run -d --name postgres --env POSTGRES_USER=postgres --env POSTGRES_DB=my_test circleci/postgres:9.6.2-alpine
/tmp/workspace/sql/t/run_tests.sh
Since the postgres container is not accessible anymore through the local network, your up check could be docker exec postgres pg_isready
You can then set your DB_HOST to postgres in your run script.
Original answer:
I'm not well versed into CircleCI configuration, but my guess would be that your Docker container you run manually is not attached to the same network as the containers launched by CircleCI.
From what I see in the documentation, you can specify the hostname of the service container:
The name the container is reachable by. By default, container services are accessible through localhost
So maybe if you try something lile this:
- image: circleci/postgres:9.6.2-alpine
name: postgres
environment:
POSTGRES_USER: postgres
POSTGRES_DB: my_test
You can then set your DB_HOST to postgres in your run script.
I have written a Dockerfile like this:
FROM postgres:11.2-alpine
ADD ./db/postgresql.conf /etc/postgresql/postgresql.conf
CMD ["-c", "config_file=/etc/postgresql/postgresql.conf"]
It just adds custom config location to a generic Postgres image.
Now I have the following docker-compose service description
db:
build:
context: .
dockerfile: ./db/Dockerfile
environment:
POSTGRES_PASSWORD passwordhere
POSTGRES_USER: user
POSTGRES_DB: db_name
ports:
- 5432:5432
volumes:
- ./run/db-data:/var/lib/db/data
The problem is I can no longer remotely connect to DB using these credentials if I add this Config option. Without that CMD line it works just fine.
If I prepend "postgres" in CMD it has the same effect due to the underlying script prepending it itself.
Provided all the files are where they need to be, I believe the only problem with your setup is that you've omitted an actual executable from the CMD -- specifying just the option. You need to actually run postgres:
CMD ["postgres", "-c", "config_file=/etc/postgresql/postgresql.conf"]
That should work!
EDIT in response to OP's first comment below
First, I did confirm that behavior doesn't change whether "postgres" is in the CMD or not. It's exactly as you said. Onward!
Then I thought there must be a problem with the particular postgresql.conf in use. If we could just figure out what the default file is.. turns out we can!
How to get the existing postgres.conf out of the postgres image
1. Create docker-compose.yml with the following contents:
version: "3"
services:
db:
image: postgres:11.2-alpine
environment:
- POSTGRES_PASSWORD=passwordhere
- POSTGRES_USER=user
- POSTGRES_DB=db_name
ports:
- 5432:5432
volumes:
- ./run/db-data:/var/lib/db/data
2. Spin up the service using
$ docker-compose run --rm --name=postgres db
3. In another terminal get the location of the file used in this release:
$ docker exec -it postgres psql --dbname=db_name --username=user --command="SHOW config_file"
config_file
------------------------------------------
/var/lib/postgresql/data/postgresql.conf
(1 row)
4. View the contents of default postgresql.conf
$ docker exec -it postgres cat /var/lib/postgresql/data/postgresql.conf
5. Replace local config file
Now all we have to do is replace the local config file ./db/postgresql.conf with the contents of the known-working-state config and modify it as necessary.
Database objects are only created once!
Database objects are only created once by the postgres container (source). So when developing the database parameters we have to remove them to make sure we're in a clean state.
Here's a nuclear (be careful!) option to
(1) remove all exited Docker containers, and then
(2) remove all Docker volumes not attached to containers:
$ docker rm $(docker ps -a -q) -f && docker volume prune -f
So now we can be sure to start from a clean state!
Final setup
Let's bring our Dockerfile back into the picture (just like you have in the question).
docker-compose.yml
version: "3"
services:
db:
build:
context: .
dockerfile: ./db/Dockerfile
environment:
- POSTGRES_PASSWORD=passwordhere
- POSTGRES_USER=user
- POSTGRES_DB=db_name
ports:
- 5432:5432
volumes:
- ./run/db-data:/var/lib/db/data
Connect to the db
Now all we have to do is build from a clean state.
# ensure all volumes are deleted (see above)
$ docker-compose build
$ docker-compose run --rm --name=postgres db
We can now (still) connect to the database:
$ docker exec -it postgres psql --dbname=db_name --username=user --command="SELECT COUNT(1) FROM pg_database WHERE datname='db_name'"
Finally, we can edit the postgres.conf from a known working state.
As per this other discussion, your CMD command only has arguments and is missing a command. Try:
CMD ["postgres", "-c", "config_file=/etc/postgresql/postgresql.conf"]
Here is the image I am using.
I named it posgres_test
If I run the image individually
docker run -i -t -v="test_volume:/var/lib/postgresql" -p 5432:5432 posgres_test
I can access it with
psql -h 192.168.99.100 -p 5432 -U pguser -W pgdb
Or I can access it with my golang app
// host is set to postgres
db, err := sql.Open("postgres", "postgres://pguser:pguser#postgres:5432/pgdb")
// table test_db is manually created.
rows, err := db.Query("SELECT name FROM test_db WHERE)
However if I use docker compose
docker-compose.yml
version: "2"
services:
postgres:
image: my_image/postgresql:9.3
volumes:
- test_volume:/var/lib/postgresql
ports:
- "5432:5432"
web:
image: my-golang-app4
ports:
- "8080:8080"
volumes:
test_volume: {}
I get the following
pguser#pgdb ERROR: relation "test_db" does not exist at character 15
I know for sure test_db exist in test_volume since
docker run -i -t -v="test_volume:/var/lib/postgresql" -p 5432:5432 posgres_test
psql -h 192.168.99.100 -p 5432 -U pguser -W pgdb
\dt
will show the table I created
But it seems like my app in docker compose cannot find it
Can someone help me out?
About your docker-compose file
First, I thought it's because you don't use the 'links' option to link your postgres container to the web container - it's good practice if you don't expand ports - but you expand postgres port.
If you want to use inheritance from the image you posted
Instead of using this line:
my_image/postgresql:9.3
use:
docker/postgres
and create path docker/postgres and there place Dockerfile with inheritance from the container you want.
I always use shared volumes in docker-compose.yml like this:
.:/var/www/html
where . is my project path where I place my code files.
Image I created to test this case
I don't have all your docker files structure to reproduce this error and fix it, so I created a docker-compose, which should match your needs or help to fix your issue:
version: '2'
services:
web:
build: docker/web
ports:
- "8080:8080"
links:
- dbpostgres
volumes:
- .:/var/www/html # I will share my code so I map this path
dbpostgres:
image: postgres
volumes:
- /private/var/lib/postgresql:/var/lib/postgresql
ports:
- "5432:5432"
environment:
POSTGRES_USER: pguser
POSTGRES_PASSWORD: pguser
POSTGRES_DB: pgdb
Notes:
I will recommend use official postgres image
I left comments next to the lines.
How I made connection:
host=dbpostgres port=5432 dbname=pgdb user=pguser password=pguser
Because my web container knows host dbpostgres (image name and domain name) now - I link them using links.
If you need database from existing container
If you need the database from your existing container just use the docker option cp to copy database locally:
docker cp posgres_test:/var/lib/postgresql /private/var/lib/postgresql
where /private/var/lib/postgresql is a path on your localhost.
You also need to change credentials to db in docker-compose to your old credentials.
You have to do it before running docker-compose because if db doesn't exist, it will be created.
Any questions, let me know.
If the volume is external and already existing before the use of docker-compose you should declare it external, or else docker compose will create a new volume with the project name as prefix.
volumes:
test_volume:
external: true
Docs for external using compose v3 (mostly similar to v2): https://docs.docker.com/compose/compose-file/compose-file-v3/#external
I think it sould be something like this for you.
docker run -itd -p 5432:5432 --name postgres_test -v /path/in/your/host :/path/in/your/container postgres_test psql -h 192.168.99.100 -p 5432 -U pguser -W pgdb
Read Docker docs(https://docs.docker.com/engine/tutorials/dockervolumes/), watch tutorials (there is a Docker Youtube channel whith great tutorials).
I have created an ubuntu image with nginx, php and postgres.
I want to connect the postgres database in my current image with pgadmin located on my local machine.
I have tried using docker inspector to try to use the image ip to make a connection with my local pgadmin but without much success. I've also tried configuring some ports on local to make connection work.
It's a valid question don't know why people feel "doesn't seem possible to answer that question".
So, here's how I do what you are trying to do:
Pull postgres image from Docker Hub
docker pull postgres:latest
Run the container using the below command
docker run -p 5432:5432 postgres
Using docker's inspect command find the IP
Use that IP, PORT, Username, and Password to connect in PGADMIN
You can also do a simple telnet like below to confirm if you can access docker postgres container:
telnet IP_ADDRESS 5432
1. Postgres with Docker
docker run \
-p 5432:5432 \
--name container-postgresdb \
-e POSTGRES_PASSWORD=admin \
-d postgres
2. PgAdmin with Docker
docker run \
-p 5050:80 \
-e "PGADMIN_DEFAULT_EMAIL=name#example.com" \
-e "PGADMIN_DEFAULT_PASSWORD=admin" \
-d dpage/pgadmin4
3. Connection string for PgAdmin
Enter PgAdmin on localhost:80. Then add a server with:
name: container-postgresdb
host: host.docker.internal
database: postgres
user: postgres
password: admin
You can also use this to find out the host address — it will be listed as IPAddress in the output —:
docker inspect container-postgresdb \
-f "{{json .NetworkSettings.Networks }}"
This other article might help with more info.
What I have done success on windows 10 running docker for windows 1.12.6(9655), the step is like below:
Pull the latest postgres
docker pull postgres:latest
run the postgres containner:
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name db-my -p 5432:5432 --restart=always postgres
Then installed the latest version of pgAdmin4 from
pgadmin website
Run pgAdmin 4 create new server, and input as following
Host: 127.0.0.1
Port: 5432
User name: user
password: password123
Then everything is ok, connect to docker postgres instance success.
Alternatively, you could combine Postgres and Pgadmin in one docker-compose file, and login as user pgadmin4#pgadmin.org, pwd: admin. To add the Posgres server, use hostname postgres, port 5432.
version: '3'
services:
postgres:
image: postgres
hostname: postgres
ports:
- "6543:5432"
environment:
POSTGRES_USER: postgres
POSTGRES_PASSWORD: postgres
POSTGRES_DB: TEST_SM
volumes:
- postgres-data:/var/lib/postgresql/data
restart: unless-stopped
pgadmin:
image: dpage/pgadmin4
depends_on:

ports:
- "5555:80"
environment:
PGADMIN_DEFAULT_EMAIL: pgadmin4#pgadmin.org
PGADMIN_DEFAULT_PASSWORD: admin
restart: unless-stopped
volumes:
postgres-data:
If you verified that PostgreSQL is running and you can connect there with local copy of PgAdmin...
The answer is simple: use host.docker.internal istead of localhost for the PgAdmin running inside the Docker
In my case I could solve the problem inspecting my postgre image through command
docker inspect CONTAINER_ID | grep IPAddress.
So, I used the docker ip address to config my pgadmin 4 connection and everything was fine. Thanks to #Afshin Ghazi
I included this in the docker yaml file to get the database and pgAdmin:
database:
image: postgres:10.4-alpine
container_name: kafka-nodejs-example-database
environment:
POSTGRES_USER: ${POSTGRES_USER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
expose:
- "5432"
ports:
- 8000:5432
volumes:
- ./services/database/schema.sql:/docker-entrypoint-initdb.d/1-schema.sql
- ./services/database/seed.sql:/docker-entrypoint-initdb.d/2-seed.sql
pgadmin:
image: dpage/pgadmin4
ports:
- 5454:5454/tcp
environment:
- PGADMIN_DEFAULT_EMAIL=admin#mydomain.com
- PGADMIN_DEFAULT_PASSWORD=postgres
- PGADMIN_LISTEN_PORT=5454
The postgres username is alphaone and the password is xxxxxxxxxxx.
Do a docker ps to get the container id and then docker inspect <dockerContainerId> | grep IPAddress
eg: docker inspect 2f50fabe8a87 | grep IPAddress
Insert the Ip address into pgAdmin and the database credentials used in docker:
If pgAdmin is intended to be run wihtin same Ubuntu host/guest, then you need to link postgres container, so it could be resolved by a name.
1. Run a postgres container:
docker run --name some-postgres -e POSTGRES_PASSWORD=postgres -d postgres
2. Run pgAdmin container:
docker run -p 80:80 --link some-postgres -e "PGADMIN_DEFAULT_EMAIL=email#domain.com" -e "PGADMIN_DEFAULT_PASSWORD=postgres" -d dpage/pgadmin4
3. Now when adding new server in phAdmin web app, use some-postgres as server name
Note the --link some-postgres when we were bringing up the pgAdmin. This command makes postgres container visible to pgAdmin container.
After facing this issue for two days i was able to resolve that issue.
solution of this problem is already answered by peoples like do inspect
docker inspect CONTAINER_ID
but while running this command i got a-lot of logs like Host Config Config Network Settings etc. so i got confused which IPAddress to add in the pgAdmin connection because i tried 0.0.0.0 and config, host, networkSettings different -2 IPAddress in the logs but finally it works after trying a-lot.
it works with which IP, we have to add that network ip address (which we created to connect the postgres and pgAdmin.)
like in my case when i run :-
docker inspect postgres_container
"NetworkSettings": {
"Bridge": "",

"Gateway": "192.168.16.1",
"IPAddress": "192.168.16.2",
"IPPrefixLen": 20,
"IPv6Gateway": "",
so we have to add the NetworkSettings -> Network -> Postgres(mine created network) -> IPAddress i.e. "IPAddress": "192.168.16.2".
After adding this ip it will work.
I hope it will help.
This worked for me on Ubuntu 18:
1- Run a postgres container
docker run -d -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password123 --name my-postgres -p 5432:5432 postgres
2- Run a pgAdmin container
docker run --rm -p 5050:5050 thajeztah/pgadmin4
3- Get your local IP (in Ubuntu by ifconfig command)
4- Open localhost:5050 in your browser
5- Click on Servers >> Create >> Server...
6- In General tab, give it a name, for example: docker. In Connection tab, enter these fields:
Host name: The IP from 3
Username: user
Password: password123
7- Click on Save and now everything should work fine.
Note: If this didn't work, try "localhost" for the host name.
In order or find your IP of the container, use following command
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

You have to expose the postgres port in the container to you local system. You do this by running your container like this:
docker run -p 5432:5432 <name/id of container>
when connecting with your GUI client or CLI make sure to use the ip-address not localhost even if your ip-address is the localhost ip-address.
docker ps would give you the ip address your postgres container is on.
In my case, I had a PostgreSQL container, so I didn't change my container or create a docker-compose approach, I needed pgadming after few months to had installed PostgreSQL, so this is my approach:
docker inspect my_container_id_postgreSQL
The network assigned to PostgreSQL was:
"Networks": {
"docker_default": {
"IPAddress": "172.18.0.2",
...
}
}
Ran my PGADMIN with --network command.
docker run -p 85:80 --network docker_default -e 'PGADMIN_DEFAULT_EMAIL=user#domain.com' -e 'PGADMIN_DEFAULT_PASSWORD=SuperSecret' -d dpage/pgadmin4
Insert the Ip address into pgAdmin and the database credentials used in docker.
I hope this can be useful for someone.
Regards.
You can create a Docker bridge network to do this too.
$ docker network create pgnet

Open http://localhost:8000/
Click Add New Server
Create - Server
Name: db
Hostname/address: pg
Username: postgres
Password: pg123
Save
The Hostname/address used above is the name of the Postgres container given by --name pg
When you start container you have network alias for it. Just use this alias in pgadmin UI.
Like if you have the following docker compose config:
version: "3.5"
services:
postgres:
container_name: postgres-14
image: postgres:14.1
restart: unless-stopped
ports:
- "5432:5432"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- POSTGRES_PASSWORD=root
- POSTGRES_USER=postgres
hostname: postgres
pgadmin:
container_name: pgadmin4
image: dpage/pgadmin4
restart: unless-stopped
ports:
- "80:80"
environment:
- POSTGRES_HOST_AUTH_METHOD=trust
- PGADMIN_DEFAULT_EMAIL=user#domain.com
- PGADMIN_DEFAULT_PASSWORD=admin
hostname: pgadmin
You can add server with hostname: postgres
For macOS IPs of postgres and pgadmin4 are different from the ones docker inspect provides.
Type
docker-machine ls
Take a look at the name of the server on the left. It's default by default.
docker-machine ip default will IP you need to use for both, pgadmin4 in browser and for postgres in pgadmin4 settings.
Are you using Window Subsystem LinuxWSL2 to run Docker and PgAdmin?
The steps I suggested is similar to what folks suggested. In my case I am using window environment
Step 1: Open CMD and type ipconfig and hit enter.
Step 2: Check WSL IPv4 Adress
Ethernet adapter vEthernet (WSL):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : 3bd9::997b:b52a::fe80::65b3%63
IPv4 Address. . . . . . . . . . . : 172.172.172.1 // use the IP as host/address
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Step 3: Open PgAdmin from the browse and create a server
Step 4:
// Here it depends on your desired config mine is the following
Server: postgres
host address: IPv4 Address(step 2)
username: postgress(username for postgress)
password: password(password for postgress)
I spend two days to figure out what was wrong, I hope someone will find it helpful
If local host port 5432 already in use by another psql servers, change it when creating the container and in Pgadmin.
What I have done success on macOS Monterrey running Docker Desktop for macOS(M1):
Pull the latest postgres:
docker pull postgres
Run the postgres container:
docker run -d -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres --name postgres-server -p 5432:5432 --restart=always postgres
Then installed the latest version of pgAdmin 4 (macOS) from pgadmin website
Run pgAdmin 4 create new server, and input as following Host: 127.0.0.1 Port: 5432 User name: postgres password: postgres
pgAdmin 4: Connection postgres-server
Here are the full steps that worked for me
Download and install pgadmin GUI tool
Run docker container: docker-compose up my-db.
From this command logs, note down ipv4 address and port. In my case, it's 0.0.0.0 and 5432.
Open docker-compose.yml file and note down POSTGRES PASSWORD
open pgadmin gui
enter name
In connection tab:
enter that ipv4 address in Hostname/address
enter that port
enter that POSTGRES PASSWORD in password
save. 🎊
To find the correct ip for your container, execute the following commands:
Check container ID:
docker ps
To check the correct IP of your container:
docker inspect <ID_CONTAINER> | grep "IPAddress"
The configuration of both PostgreSQL and PgAdmin with Docker are simple, if not right, I recommend redoing the configuration from scratch, if your problem is deeper.
Here is a script I developed to solve this problem.
script-sh/install-docker-postgres-and-pgadmin
I did not connect with my container pg (dpage/pgadmin4 image) from browser on 0.0.0.0:9090 .
I ran this command :
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' -d dpage/pgadmin4
Solution one :
First I tried to inspect the container for IP address
docker inspect pg
I got the container IP address "IPAddress": "172.17.0.3". http://172.17.0.3:9090 did not accessible.
Solution two :
And then I ran command without de-attached mode (-d removed)
docker run --name pg -p 9090:9090 -e PGADMIN_DEFAULT_EMAIL='faizan' -e PGADMIN_DEFAULT_PASSWORD='faizan' dpage/pgadmin4
# Output, it should be running on 9090.
Listening at: http://[::]:80
-p 9090:9090 did not work.
Finally I found the solution :
On some filesystems that do not support extended attributes, it may
not be possible to run pgAdmin without specifying a value for
PGADMIN_LISTEN_PORT that is greater than 1024. In such cases, specify
an alternate port when launching the container by adding the
environment variable, for example:
-e 'PGADMIN_LISTEN_PORT=5050'
Don’t forget to adjust any host-container port mapping accordingly.
Read more about it official doc
I added -e 'PGADMIN_LISTEN_PORT=9090' and worked for me.
You can try both solutions, it will definitely work for you.
I ran this, It worked for me
docker pull dpage/pgadmin4
docker run -p 9000:80 -e 'PGADMIN_DEFAULT_EMAIL=test#gmail.com' -e 'PGADMIN_DEFAULT_PASSWORD=root' -d dpage/pgadmin4
The solution I tried and worked for me, was to create a docker compose file where I included postgress and pgadmin as services. For more details: Connecting pgadmin to postgres in docker
Tested on Mac
pgAdmin-4: version 6.12
I tried several answers here and in other places but nothing worked for me.
Here is the problem I had and the solution.
I had a docker postgres running my machine and need to connect this server in pgAdmin.
All I need to do was to check the docker information and fill the server configs based on that in pgAdmin.
You can do this by opening your docker and going to dashboard and then selecting the postgres image you're using. There is a tab called Inspect click on that. Here you can get all the information about that postgres container.
Now open the pgAdmin and resister a server by right clicking on the servers -> Register -> Server.
choose a name for the server and click Connection tab.
Here we need to fill the data like host name/address, IP, ports and etc.
In docker Inspect tab, there is Ports section that you can get this data from, something like this:
So your host address based on this picture is 172.0.0.1 and port is 5873.
Other info like database, user and password is also available in Environment section in docker Inspect tab.
Now fill the other information click save in pgAdmin and it should work.
Go to your container terminal on Docker Desktop and type hostname -I in case is linux to get the ip assigned to this machine, then go to your pgAdmin an try it out. #Rigoxls
