Best practice for docker compose passwords? (self.docker)

submitted 1 year ago by hyper to c/[email protected]

For example I have a docker compose stack with a service and a db.
How do you handle the passwords? Is it better to store them in a .env file or is there something different entirely?

Also do the passwords have to be strong if the db is only available to the service through the docker network?

regarding docker secrets: what @[email protected] said, examples for doing this are here: https://docs.docker.com/compose/use-secrets/

regarding passwords: maybe you don't "have to", but if i'd argue it's important to build a habit of never using weak passwords anywhere. using strong passwords shouldn't be/feel like an extra step but part of the normal workflow.

For passwords in software chains, I always think of them as API keys. So, making them 32 or 64 character random strings doesn't seem ridiculous.
