I would like to access my Postgres database (docker container) from PhpStorm.
docker-compose.yml
# Run docker-compose build
# Run docker-compose up
# Live long and prosper
version: '3.1'
services:
apache:
build: .docker/apache
container_name: sf-apache
ports:
- 82:80
volumes:
- .docker/config/vhosts:/etc/apache2/sites-enabled
- ${SYMFONY_APP}:/home/wwwroot/sf3
depends_on:
- php
postgres:
container_name: postgres
restart: always
image: 'postgres:12.6'
ports:
- "5432:5432"
environment:
- "POSTGRES_USER=${PGSQL_ADMIN_USER}"
- "POSTGRES_PASSWORD=${PGSQL_ADMIN_PASSWORD}"
volumes:
- ./API/var/postgres:/var/lib/postgresql/data
- .docker/postgresql/init-database.sh:/docker-entrypoint-initdb.d/init-database.sh
My PhpStorm config :
I can access to my database via docker exec -it postgres bash
If php storm is on the same host then you need to use localhost. If both phpstorm and pg is part of the same compose file , then you would use the service name since both would be in the same virtual network
I found the solution.
I have a Postgres local and a Postgres with docker. My Postgres local get the upper hand on my docker Postgres. I have killed the service and put the container service name on it.
Works perfectly.
Thanks for you help,

I'm set up docker compose for my project with 2 services: spring-boot and postgresql. I created Dockerfile and docker-compose,yml as below:
Dockerfile :
FROM openjdk:8-jdk-alpine
MAINTAINER linhan.com
COPY target/LinhAn-0.0.1-SNAPSHOT.jar linhan-server-1.0.0.jar
ENTRYPOINT ["java","-jar","/linhan-server-1.0.0.jar"]
docker-compose.yml:
version: '2'
services:
spring_boot:
image: 'linhan'
build: .
container_name: api
ports:
- "8080:8080"
depends_on:
- postgres
environment:
- SPRING_DATASOURCE_URL=jdbc:jdbc:postgresql://localhost:5432/test_db
- SPRING_DATASOURCE_USERNAME=user
- SPRING_DATASOURCE_PASSWORD=123456
- SPRING_JPA_HIBERNATE_DDL_AUTO=update
postgres:
image: 'postgres:13.1-alpine'
container_name: db
environment:
- POSTGRES_USER=user
- POSTGRES_PASSWORD=123456
Then, when I type docker-compose up in terminal, postgres ran only, spring boot still not.
I searched google for solution but seems no hope. Please help me, thanks a lot!!!!!
I think you need to change the SPRING_DATASOURCE_URL to reference your service name instead of localhost. The service name is resolved automatically to your service since all services are part of the default_network by default in docker-compose.
- SPRING_DATASOURCE_URL=jdbc:jdbc:postgresql://postgres:5432/test_db
Also, for clarity I would suggest you add the port to your docker-compose postgres service, so it is clear which port is being used, even if it is the default:
postgres:
image: 'postgres:13.1-alpine'
container_name: db
ports:
- "5432"
environment:
- POSTGRES_USER=user
- POSTGRES_PASSWORD=123456
Also, another suggestion would be to try and use a healthcheck to see if your database service becomes available instead of a simple depends_on. The short version will mark the dependency fulfilled as soon as the container is Running, regardless of the availability of the database.
Either that, or you can add application logic to retry database connection in case of failure.
I have a Java Spring Boot app which works with a Postgres database. I want to use Docker for both of them. I initially put just the Postgres in Docker, and I had a docker-compose.yml file defined like this:
version: '2'
services:
db:
container_name: sample_db
image: postgres:9.5
volumes:
- sample_db:/var/lib/postgresql/data
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
- PGDATA=/var/lib/postgresql/data/pgdata
ports:
- 5432:5432
volumes:
sample_db: {}
Then, when I issued the commands sudo dockerd and sudo docker-compose -f docker-compose.yml up, it was starting the database. I could connect using pgAdmin for example, by using localhost as server and port 5432. Then, in my Spring Boot app, inside the application.properties file I defined the following properties.
spring.datasource.url=jdbc:postgresql://localhost:5432/sample
spring.datasource.username=sample
spring.datasource.password=sample
spring.jpa.generate-ddl=true
At this point I could run my Spring Boot app locally through Spring Suite, and it all was working fine. Then, I wanted to also add my Spring Boot app as Docker image. I first of all created a Dockerfile in my project directory, which looks like this:
FROM java:8
EXPOSE 8080
ADD /target/manager.jar manager.jar
ENTRYPOINT ["java","-jar","manager.jar"]
Then, I entered to the directory of the project issued mvn clean followed by mvn install. Next, issued docker build -f Dockerfile -t manager . followed by docker tag 9c6b1e3f1d5e myuser/manager:latest (the id is correct). Finally, I edited my existing docker-compose.yml file to look like this:
version: '2'
services:
web:
image: myuser/manager:latest
ports:
- 8080:8080
depends_on:
- db
db:
container_name: sample_db
image: postgres:9.5
volumes:
- sample_db:/var/lib/postgresql/data
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
- PGDATA=/var/lib/postgresql/data/pgdata
ports:
- 5432:5432
volumes:
sample_db: {}
But, now if I issue sudo docker-compose -f docker-compose.yml up command, the database again starts correctly, but I get errors and exit code 1 for the web app part. The problem is the connection string. I believe I have to change it to something else, but I don't know what it should be. I get the following error messages:
web_1 | 2017-06-27 22:11:54.418 ERROR 1 --- [ main] o.a.tomcat.jdbc.pool.ConnectionPool : Unable to create initial connections of pool.
web_1 |
web_1 | org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections
Any ideas?
Each container has its own network interface with its own localhost. So change how Java points to Postgres:
spring.datasource.url=jdbc:postgresql://localhost:5432/sample
To:
spring.datasource.url=jdbc:postgresql://db:5432/sample
db will resolve to the proper Postgres IP.
Bonus. With docker-compose you don't need to build your image by hand. So change:
web:
image: myuser/manager:latest
To:
web:
build: .
I had the same problem and I lost some time to understand and solve this problem:
org.postgresql.util.PSQLException: Connection to localhost:5432 refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
I show all the properties so that everyone understands.
application.properties:
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.username=postgres
spring.datasource.password=postgres
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL82Dialect
spring.jpa.hibernate.ddl-auto=update
docker-compose.yml:
version: "3"
services:
springapp:
build: .
container_name: springapp
environment:
SPRING_DATASOURCE_URL: jdbc:postgresql://db:5432/testdb
ports:
- 8000:8080
restart: always
depends_on:
- db
db:
image: postgres
container_name: db
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
- POSTGRES_DB=testdb
- PGDATA=/var/lib/postgresql/data/pgdata
ports:
- 5000:5432
volumes:
- pgdata:/var/lib/postgresql/data
restart: always
volumes:
pgdata:
For start spring application with local database we use url localhost.
For connect to container with database we need change 'localhost' on your database service, in my case 'localhost' to 'db'.
Solution: add SPRING_DATASOURCE_URL environment in docker-compose.yml wich rewrite spring.datasource.url value for connect:
environment:
SPRING_DATASOURCE_URL: jdbc:postgresql://db:5432/testdb
I hope this helps someone save his time.
You can use this.
version: "2"
services:
sample_db-postgresql:
image: postgres:9.5
ports:
- 5432:5432
environment:
- POSTGRES_PASSWORD=sample
- POSTGRES_USER=sample
- POSTGRES_DB=sample
volumes:
- sample_db:/var/lib/postgresql/data
volumes:
sample_db:
You can use ENV variable to change the db address in your docker-compose.
Dockerfile:
FROM java:8
EXPOSE 8080
ENV POSTGRES localhost
ADD /target/manager.jar manager.jar
ENTRYPOINT exec java $JAVA_OPTS -jar manager.jar --spring.datasource.url=jdbc:postgresql://$POSTGRES:5432/sample
docker-compose:
`
container_name: springapp
environment:
- POSTGRES=db`
I am trying to link an external postgres to tryton/tryton from docker hub.
docker-compose.yaml
version: '3.7'
services:
tryton-postgres:
image: postgres
ports:
- 5432:5432
environment:
- POSTGRES_PASSWORD=password
- POSTGRES_DB=tryton
restart: always
gnuserver:
image: tryton/tryton:4.6
links:
- tryton-postgres:postgres
ports:
- 8000:8000
depends_on:
- tryton-postgres
entrypoint: /entrypoint.sh trytond
when i ssh into the container and run trytond-admin --all -d tryton it seems to be looking for sqlite file instead of the connected postgres database. Are there some env variagbles i must set? What am i missing in my docker compose file?
Instead of changing the configuration file, with Docker it is simpler to set environment variable like:
DB_USER=
DB_PASSWORD=
DB_HOSTNAME=tryton-postgres
DB_PORT=5432
you need to edit /etc/tryton/trytond.conf to look at postgresql:
uri = postgresql://USERNAME:PASSWORD#tryton-postgres:5432/

How to access postgres-docker container other docker container without ip address?
I want to store data in postgres by using myweb. in jar given host like localhost:5432/db..
Here my compose file:
version: "3"
services:
myweb:
build: ./myweb
container_name: app
ports:
- "8080:8080"
- "9090:9090"
networks:
- front-tier
- back-tier
depends_on:
- "postgresdb"
postgresdb:
build: ./mydb
image: ppk:postgres9.5
volumes:
- dbdata:/var/lib/postgresql
ports:
- "5432:5432"
networks:
- back-tier
volumes:
dbdata: {}
networks:
front-tier:
back-tier:
Instead of localhost:5432/db.. use postgresdb:5432/db.. connection string.
By default the container has the same hostname as the service name.
Here is my minimal working example, which is connecting a java client (boxfuse/flyway) with postgres server. The most important part is the heath check, which is delaying the start of the myweb container to the time when postgres is ready to accept connections.
Note that this can be directly executed by docker-compose up, it dosen't have any other dependencies. Both the images are from docker hub.
version: '2.1'
services:
myweb:
image: boxfuse/flyway
command: -url=jdbc:postgresql://postgresdb/postgres -user=postgres -password=123 info
depends_on:
postgresdb:
condition: service_healthy
postgresdb:
image: postgres
environment:
- POSTGRES_PASSWORD=123
healthcheck:
test: "pg_isready -q -U postgres"
That is the Docker Networking problem. The solution is to use postgresdb:5432/db in place of localhost:5432/db because the two service is in the same network named back-tier and docker deamon will use name service like a DNS name to make communication between the two container. I think that my solution will help you so.
I have a multiple container application, that is using the postgres image in docker-compose.yml file. Postgres container has volume on host machine for persistent storage.
When I run docker-compose up at first time all is fine, postgres creates db files in my host folder.
After it I need to shut down application temporarily with docker-compose down if I'll change code of web container.
When I run docker-compose up second time, postgres overwriting all db files, but I need that data not changes. How can I solve this issue?
My docker-compose.yml
version: '2'
services:
web:
build: ./web
command: python3 main.py
volumes:
- ./web:/app
ports:
- "80:80"
depends_on:
- db
- redis
links:
- db:db
- redis:redis
db:
image: postgres
ports:
- "5432:5432"
environment:
- POSTGRES_PASSWORD:0000
volumes:
- ./pgdb:/var/lib/postgresql/data
redis:
image: redis
ports:
- "6379:6379"
command: redis-server --appendonly yes
volumes:
- ./redisdb:/data
I solve this problem. It occurs probably because I changed permissions for pgdb directory with host root user. By default I couldn't open pgdb in host machine because owner is postgres user. I could be wrong but after I stopped to change the resolutions the problem was gone.
