postgres-1  | Error: Database is uninitialized and superuser password is not specified.
postgres-1  |        You must specify POSTGRES_PASSWORD to a non-empty value for the
postgres-1  |        superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
postgres-1  |
postgres-1  |        You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
postgres-1  |        connections without a password. This is *not* recommended.
