⁠Launching PostgreSQL

⁠Quick Start (not recommended for production use)

To connect to the container as the administrative postgres user:

docker run -it --rm --volumes-from=postgresql <yourname>/postgres sudo -u
postgres -H psql

⁠Creating a database at launch

You can create a postgresql superuser at launch by specifying DB_USER and DB_PASS variables. You may also create a database by using DB_NAME.

docker run --name postgresql -d \
-e 'DB_USER=username' \
-e 'DB_PASS=ridiculously-complex_password1' \
-e 'DB_NAME=my_database' \
<yourname>/postgresql

To connect to your database with your newly created user:

psql -U username -h $(docker inspect --format {{.NetworkSettings.IPAddress}} postgresql)
