Experiment with using Docker Secrets (but not in Swarm mode)

[kowh-ai]

Following on from conversations with pwalsh I will investigate how using Docker secrets (while not in Docker Swarm mode) give's any advantage over the PR: #76

For reference:
https://docs.docker.com/compose/use-secrets/
https://gist.github.com/brianjbayer/966769aa0b00bb95b266827862dd511e
docker/compose#4368

• Easy enough to get (local) secrets running
• Creates "secret" files on the running container as /run/secrets/<secret name>
• file content is in plain text

ok. so it means that, it is "as secure" as using environment variables, but, provides a seamless path to a secure implementation, if going from Compose to Swarm. That might not be very compelling unless we know people are using Docker Swarm.

Another alternative to using Swarm to just manage secrets in Docker Compose could be to investigate using an external Vault system to manage secrets in Docker Compose eg: Hashicorp Vault or Mozilla SOPS. If it's feasible then perhaps just a Howto Wiki Page in the ckan-docker repo would be helpful for people wanting a more secure Docker environment
