Environment Variables

POSTGRES_PASSWORD

This environment variable is recommend for you to use the PostgreSQL image. This environment variable sets the superuser password for PostgreSQL. The default superuser is defined by the POSTGRES_USER environment variable. In the above example, it is being set to “mysecretpassword”.

POSTGRES_USER

This optional environment variable is used in conjunction with POSTGRES_PASSWORD to set a user and its password. This varible will create the specified user with superuser power and a database with the same name. If it is not specified, then the default user of postgres will be used.
