I created docker-compose.yml which content you can find below. I navigate to the folder where file resist and run command:
docker-compose up -d
This was shown:
Starting postgres ... done
then i run that query:
docker-compose ps
Result:
Name Command State Ports
---------------------------------------------------------
postgres docker-entrypoint.sh postgres Exit 1
Now i wanted to run some command:
docker exec -it postgres psql -h localhost -p 54320 -U robert
This is what i get:
Error response from daemon: Container ae1565a84bcf0b3662b47d4f277efd2830273554b6bcf4437129e33b31c88b35 is not running
Is my container not running or? please of support.
docker-compose.yml:
version: "3"
services:
# Create a service named db.
db:
# Use the Docker Image postgres. This will pull the newest release.
image: "postgres"
# Give the container the name my_postgres. You can changes to something else.
container_name: "postgres"
# Setup the username, password, and database name. You can changes these values.
environment:
- POSTGRES_USER=robert
- POSTGRES_PASSWORD=robert
- POSTGRES_DB=mydb
# Maps port 54320 (localhost) to port 5432 on the container. You can change the ports to fix your needs.
ports:
- "54320:5432"
# Set a volume some that database is not lost after shutting down the container.
# I used the name postgres-data but you can changed it to something else.
volumes:
- ./volumes/postgres:/var/lib/postgresql/data
Can you attempt exec
docker run -it postgres psql -h localhost -p 54320 -U robert
?
$ docker exec --help
Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...]
Run a command in a running container
Since your container has the status exit, you can't use docker exec
Can you use this docker-compose file?
version: "3"
volumes:
postgres_app: ~
services:
# Create a service named db.
postgres:
image: "postgres"
environment:
POSTGRES_USER: robert
POSTGRES_PASSWORD: robert
POSTGRES_DB: "mydb"
volumes:
- "postgres_app:/var/lib/postgresql/data"
ports:
- "54320:5432"
restart: always
And this command docker-compose exec postgres psql -U robert -d mydb
I hope this will help!

Windows 10-Pro. Have a local Postgres installed and working fine.
With it running, VSC terminal, docker-compose up the following ok:
version: '3.8'
services:
postgres:
image: postgres:10.4.2
ports:
- '5432:5432'
volumes:
- ./sql:/docker-entrypoint-initdb.d
environment:
POSTGRES_USER: user
POSTGRES_PASSWORD: pass1
POSTGRES_DB: db
But PSQL shell always complain password authentication failed for user.
Stopping postgres service from Windows Services and docker-compose up, PSQL shell authentication and query ok. But VSC terminal keep complaining another thing:
FATAL: password authentication failed for user "postgres"
DETAIL: User "postgres" has no password assigned.
Connection matched pg_hba.conf line 95: "host all all all md5"
How to stop the above error when docker container's instance is running? Also, possible to co-run both local and docker?
Hope you are enjoying you containers journey !
I tried to execute your docker-compose as it was but cannot fetch the postgres:10.4.2 image:
❯ docker-compose up
[+] Running 0/1
⠿ postgres Error 2.1s
Error response from daemon: manifest for postgres:10.4.2 not found: manifest unknown: manifest unknown
so i decided to use postgres:14.2 instead. Since I dont have your sql script i'll comment out the volume section.
Here is how my docker-compose looks like:
version: '3.8'
services:
postgres:
image: postgres:14.2
ports:
- '5432:5432'
# volumes:
# - ./sql:/docker-entrypoint-initdb.d
environment:
POSTGRES_USER: user
POSTGRES_PASSWORD: pass1
POSTGRES_DB: db
So, when a execute the compose I got this:
❯ docker-compose up -d
[+] Running 1/1
⠿ Container postgre-local-and-dockercompose-71984505-postgres-1 Started
❯ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS
NAMES
4b90573f6108 postgres:14.2 "docker-entrypoint.s…" 18 seconds ago Up 15 seconds 0.0.0.0:5432->5432/tcp postgre-local-and-dockercompose-71984505-postgres-1
When i connect to the container with:
❯ docker exec -it postgre-local-and-dockercompose-71984505-postgres-1 bash
root#4b90573f6108:/#
and execute this command to connect to your created DB and connect with the "pass1" password:
root#4b90573f6108:/# psql --username=$POSTGRES_USER -W --host=localhost --port=5432 --dbname=$POSTGRES_DB
Password:
psql (14.2 (Debian 14.2-1.pgdg110+1))
Type "help" for help.
db=#
everything is fine.
So I advise you to use the same postgres:14.2 image i tried with (patched with the last security issues) and do the same test.
If you want me to test exactly what you are doing just send your sql scripts.
To answer your second question, yes it is possible to co-run both local and docker postgres instances
you just have to port-forward the postgresql port of your container to another port like this:
version: '3.8'
services:
postgres:
image: postgres:14.2
ports:
- '5433:5432'
# volumes:
# - ./sql:/docker-entrypoint-initdb.d
environment:
POSTGRES_USER: user
POSTGRES_PASSWORD: pass1
POSTGRES_DB: db
since there is no port conflict (your local db is running on 5432 and your docker db on 5433), everything will work fine (I will use dbeaver to try to connect ):
PERFECT !
Hope I answered your questions.
bguess.
I've been created a docker container of postgres service, but on start it and try to connect in database I get erros like I didn't defined a user and database to Postgres instance, I already tried to change the docker-compose and find the poblem but I didn't find.
Follow the attachments:
Dockerfile:
FROM wyveo/nginx-php-fpm:latest

- POSTGRES_DB=db_prm
ports:

volumes:

**when I try to connect to the database directly through the container's bash, I get an error that user and database, both being inserted in the same way as defined in docker-compose.yml, do not exist.
sudo docker container <postgres_container_id> bash
psql -h localhost -U db_usr
... and so on...
And to set up connection in pgAdmin I got the container IP using:
sudo docker container inspect <postgres_container_id>
and getting the value from IPAddress atribute.
It's been few days I am blocked on this problem with my project, it's working on localhost but not on gitlabCI.
I would like to build a test database on the postgres docker image in gitlabCI but it doesn't work, I have try a lot of things and lose a lot of hours before ask this there :'(.
below my docker-compose.yml file :

- exit
- docker exec -i monapp ./node_modules/.bin/env-cmd -f ./env/.env.builded-test npx jasmine spec/auth_queries.spec.js
- exit
this is the content of docker ps log on gitlabCI server :
docker ps on gitlab-CI
I thought to put postgres on host would work, but no I always have in gitlab-ci terminal:
psql: could not connect to server: Connection refused
Is the server running on host "postgres" (172.19.0.2) and accepting
TCP/IP connections on port 5432?
I also tried to put docker on host but error :
psql: could not translate host name "docker" to address: Name or service not known
little precision : it is working on localhost of my computer when i am doing make builded-test
bellow my makefile:
builded-test:
docker build -t monimage .
docker-compose up -d
docker ps
docker exec -i postgres psql -U postgres -h postgres -f /home/dumps/test/dump_test_001 -c \\q
exit
docker exec -i monapp ./node_modules/.bin/env-cmd -f ./env/.env.builded-test npx jasmine spec/auth_queries.spec.js
exit
docker-compose down
I want to make work postgres image in my docker-compose on gitlab CI to execute my tests help me please :) thanks by advance
UPDATE
Now it working in gitlab-runner but still not on gitlab when I push, I update the files like following
I added :
variables:
POSTGRES_DB: postgres
POSTGRES_USER: postgres
POSTGRES_PASSWORD: ""
POSTGRES_HOST_AUTH_METHOD: trust
and changed
test:
stage: test
script :
- docker build -t monimage .
- docker-compose up -d
- docker ps
- docker exec postgres psql -U postgres **-h postgres** -f /home/dumps/test/dump_test_001
- docker exec monapp ./node_modules/.bin/env-cmd -f ./env/.env.builded-test npx jasmine spec/auth_queries.spec.js
in the .gitlab-ci.yml
but still don't work when I push it to gitlab, it give me :
sql: could not connect to server: Connection refused
Is the server running on host "postgres" (172.19.0.2) and accepting
TCP/IP connections on port 5432?
any ideas ? :)
Maybe you need to wait for PostgreSQL service to be up and running.
Can you add a 10 seconds delay before trying the psql stuff? Something like:
- sleep 10
If it works, then you can use a more specific solution to wait for PostgreSQL to be initialized, like Docker wait for postgresql to be running
Context
I need to populate a database inside a docker container from a backup file that I have on the host machine.
I've tried this docker command while the PostGIS container is up (see docker-compose.yml at the end):
sudo docker exec -i db_container_1 ./usr/local/bin/pg_restore --no-owner --role=postgres -h localhost -U postgres -p 5434 -d database_name < ../db/dumps/dump_prod_2020.backup
But I've got this message:
read unix #->/var/run/docker.sock: read: connection reset by peer
As documented here, I also tried using this docker-compose command but it raises the exact same strange message:
docker-compose exec -T db /usr/local/bin/pg_restore --no-owner --role=postgres -h localhost -U postgres -p 5434 -d database_name < ../db/dumps/dump_prod_2020.backup
Question
What am I doing wrong and how could I populate my docker database with my local dump?
More infos
Here's the docker-compose.yml used to start the db service (docker ps outputs db_container_1 as the corresponding container name):
version: '3.6'
volumes:
db_data:
services:
db:
image: mdillon/postgis:11-alpine
environment:
POSTGRES_DB: database_name
POSTGRES_USER: postgres
POSTGRES_PASSWORD: password
ports:
- '${DB_PORT:-5434}:5432'
restart: 'no'
volumes:
- './docker/db:/docker-entrypoint-initdb.d:ro'
- 'db_data:/var/lib/postgresql/data' # to persist storage
I am using docker compose to combine 2 images (tomcat with my app and database - postgres).
My compose file looks like this :
version: '3'
services:
tomcat:
build: ./tomcat-img
ports:
- "8080:8080"
depends_on:
- "db"
db:
build: ./db-img
volumes:
- db-data:/var/lib/postgres/data
ports:
- "5433:5432"
volumes:
db-data:
and here is dockerfile for database image:
FROM postgres:9.5-alpine
ENV POSTGRES_DB mydb
ENV POSTGRES_USER xxxx
ENV POSTGRES_PASSWORD xxxx
COPY init-db.sql /docker-entrypoint-initdb.d/
EXPOSE 5432
CMD ["postgres"]
Next I started my containers with docker-compose cli docker-compose -f docker-compose.yml up
and run psql tool with:
docker exec -it container_id psql -d xxxx -U xxxx
and insert new record. After that I check if there really is:
select * from my_table;
After that I tried stopped docker compose and remove containers with:
docker-compose -f docker-compose.yml down
and start it again
docker-compose -f docker-compose.yml up
when I run again psql tool of db container and select data in my_table, there is no previous inserted record ... Can you help me to fix it please? I need init my db with init-db.sql just once and next using that persist storage. Thanks for answers.
In my dockerized Postgresql with a data volume I am binding to /var/lib/postgresql and not to /var/lib/postgres/data. Try changing your compose file to
volumes:
- db-data:/var/lib/postgresql
