Docker image to run a PostgreSQL database in a docker container with multiple users and databases.
Image is based of the official postgres:12 image. It modifies the docker-entrypoint.sh to allow setup of multiple users and databases. Therefore there are two new environment variables that can be set POSTGRES_USERS and POSTGRES_DATABASES. The functionality of POSTGRES_USER and POSTGRES_DB is unimpeded. If set the given user and database will be created in addition to the other given users.
docker run -p 5432:5432 --name postgres-multi
-e POSTGRES_USERS="user1:password1|user2:password2|user3:password3"
-e POSTGRES_DATABASES="db1:user1|db2:user2|db3:user3"
-it --rm lmmdock/postgres-multi
