Docker dependency

[yusf]

I'm interested in hearing opinions about Cloudron's dependency on Docker as specific container system. Depending on the well-being of the Docker company are not without its concerns, I think, if one wants to build the most resilient piece of software. I started to think on this when discovering Podman.

Was there any new news on docker, the company? The upstream repo is atleast quite active - https://github.com/moby/moby . I don't have much experience with podman to comment (nor do I know anyone who uses podman).

@yusf Podman just isn't baked yet, and docker is far, far more developed than the compitition.
See:
https://www.docker.com/blog/announcing-the-compose-specification/

docker isn't going anywhere

I’m not saying podman is a replacement, it’s just an example for discussion.

I’ve read that Docker have struggled a bit financially in the last year or so. This article is from 2019 so I don’t know how it turned out, but I think it’s a discussion worth having if they’ve had problems raising capital.

Besides the actual docker Cloudron addon, which is rarely used, we tried to keep Docker not heavily exposed to the actual users. For a start it should just be a technical detail only interesting to the app packagers. In theory once Docker goes unmaintained, we could migrate to something else, of course this is a lot of work and just a last resort, but theoretically possible the way we built Cloudron.

@nebulon said in Docker dependency:

This is good enough for me!

At the risk of highjacking this thread, I'm curious about this discussion because I was hoping to install Docker. I need to it to install and run a CAD/BIM server app.

So is Docker it actually available on Cloudron in some fashion?

[yusf]

@christiaan Hijack confirmed. But to answer your question: yes, Docker is available in Cloudron. In fact, the system is completely built around it. That does not mean that it’s a good idea to run extra containers outside the Cloudron context, however.

I can attest that it is definitely NOT a good idea to add more Docker images to a CR box outside of CR. CR assumes it has full use of the box, so, anything additional you add can and possibly will break things
