postgres:
    image: eu.gcr.io/your-project/postgres-multi-db
    environment:
        - POSTGRES_MULTIPLE_DATABASES=database1:username1:password1,database2:username2,password2
        - POSTGRES_USER=username
        - POSTGRES_PASSWORD=password
        - POSTGRES_DB=database
⁠Database and username (database:username)
postgres:
    image: eu.gcr.io/your-project/postgres-multi-db
    environment:
        - POSTGRES_MULTIPLE_DATABASES=database1:username1,database2:username2
        - POSTGRES_USER=username
        - POSTGRES_PASSWORD=password
        - POSTGRES_DB=database

Passwords will default to the value of POSTGRES_PASSWORD.

    environment:
        - POSTGRES_MULTIPLE_DATABASES=database1:username1:password1,database2:username2,database3
        - POSTGRES_USER=username
