Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

I haven't seen this posted yet here, but anybody self-hosting OwnCloud in a containerized environment may be exposing sensitive environment variables to the public internet. There may be other implications as well.

The only thing that makes this case worse in docker is that more info is in ENV variables. The vulnerability has nothing to do with containers though, and using ENV variables to provide sensitive data is in general a bad decision, since they can be leaked to any process with /proc access.

Unfortunately, ENV is still a common way which people use to pass data to applications inside containers, but it is not in any way a requirement imposed by the tech.

what are the other alternatives to ENV that are more preferred in terms of security?

A named volume for the config directory for one.

That's just as insecure lol, env vars are far better
