In orderto start PostgreSQL with Docker-compose, just run: $ docker-compose upĪs we have named our service “postgres”, we can run into the bash of the Container with just: $ docker-compose run postgres bash In our case, we will locally store the Database data in the current “data” directory. Within this file, we have also declared a Volume so that Database data will survive a Container restart. Once that you have installed it, just create a docker-compose.yml file as the following one: version: '3.5' +-+-+-+-+-įinally, it worth mentioning that managing PostgreSQL Database is a lot easier if you use Docker-compose. Name | Owner | Encoding | Collate | Ctype | Access privileges Example: docker exec -it pg psql -Upostgres -a pg_database -c '\l' Template1 | postgres | UTF8 | en_US.utf8 | en_US.utf8 | =c/postgres +Īn useful shortcut to execute SQL Commands, is the docker exec command which allows us to return the output of a SQL Command from the Host machine in just one command. Template0 | postgres | UTF8 | en_US.utf8 | en_US.utf8 | =c/postgres + Postgres | postgres | UTF8 | en_US.utf8 | en_US.utf8 | Pg_database | postgres | UTF8 | en_US.utf8 | en_US.utf8 | Try listing the Database schemas: pg_database=# \l Now, launch the psql, passing as arguent the Database name ad the Username: psql pg_database postgres If we want to enter the psql tool, first change the user to: su postgres Now start PostgreSQL version 10.5 from the shell as follows (replace credentials with the one you need): docker run -name pg -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=changeme -e POSTGRES_DB=pg_database -p 5432:5432 postgresĪs we have named the Container image as “pg” we can use this alias to connect to the Container as follows: $ docker exec -it pg bash Make sure Docker is started: $ sudo service docker start

In this tutorial we will learn how to manage PostgreSQL Database from a Docker container.įirst off, let’s learn how to start a PostgreSQL Database using Docker. In this scenario, using a Container image of the Database can speed up your development/testing. Many times we need to quickly access a Database while developing and testing applications.
