Docker PostgreSQL Database Permission Denied

Question

I try to create super user on docker bulid i face problem db issue

This is my code database config

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'smart_home_iot',
        'USER': 'enigma',
        'PASSWORD': '123',
        'HOST': '0.0.0.0',
        'PORT': '5432',
    }
}

if env.str("DATABASE_URL", default=None):
    DATABASES = {
        'default': env.db()
    }

    db_from_env = dj_database_url.config(conn_max_age=600)
    DATABASES['default'].update(db_from_env)

This is my docker file

COPY ./Pipfile ./Pipfile.lock /
RUN PIPENV_VENV_IN_PROJECT=1 pipenv install --deploy
