Support for Docker Secrets

[juliangrube1988]

Is your feature request related to a problem? Please describe.
Id like to use QuantumLeap in a Docker Compose file using Docker secrets to configure POSTGRES_DB_NAME, POSTGRES_DB_USER and POSTGRES_DB_PASS.

Describe the solution you'd like
If environment variable POSTGRES_DB_NAME_FILE, POSTGRES_DB_USER_FILE and POSTGRES_DB_PASS_FILE is set, try to read from specified path and set value like for example: https://hub.docker.com/_/postgres and https://hub.docker.com/_/mysql.

hi @juliangrube1988 :-)

Thanks for the suggestion, but we only use Docker for testing in dev environments where using plain text passwords is obviously not an issue. For production, we run on K8s and use K8s secrets.

That said, you're welcome to contribute this feature yourself :-)
