Found in this reddit post. The lacking encryption in Komodo is something I miss and I'm not satisfied with how to handle .env files plus it's really big for what it's doing. Of course I discover this the day after migrating one of the last stacks to Komodo but I'm tempted to give this a try at some point.

Full Quote from the reddit post:

Hey all, I just felt like making a post about a project that I feel like is the most important and genuinely game changing pieces of software I've seen for any homelab. It's called Doco-CD.

I know that's high praise. I'm not affiliated with the project in any way, but I really want to get the word out.

Doco-CD is a docker management system like Portainer and Komodo but is WAY lighter, much more flexible, and Git focused. The main features that stand out to me:

Native encryption/decryption via SOPS and Age

Docker Swarm support

And runs under a single, tiny, rootless Go based container.

I would imagine many here have used Kubernetes, and Git-Ops tools like FluxCD or ArgoCD and enjoyed the automation aspect of it, but grown to dislike Kubernetes for simple container deployments. Git Ops on Docker has been WAY overshadowed. Portainer puts features behind paid licenses, Komodo does much better in my opinion, but to get native decryption to work it's pretty hacky, has zero Docker Swarm support (and removed a release for it's roadmap), and is a heavier deployment that requires a separate database.

Doco-CD is the closest thing we have to a true Git Ops tool for Docker, and I just came across it last week. And beforehand I've desperately wanted a tool such as this. I've since deployed a ton of stuff with it and is the tool I will be managing the rest of my services with.

It seems to be primarily developed by one guy. Which is in part why I want to share the project. Yet, he's been VERY responsive. Just a few days ago, bind mounts weren't working correctly in Docker Swarm, I made an issue on Github and within hours he had a new version to release fixing the problem.

If anyone has been desperately wanting a Docker Git Ops tool that really does compete with feature parity with other Kubernetes based Git Ops tools. This is the best one out there.

I think for some the only potential con is it has no UI. (Like FluxCD) Yet, in some ways that can be seen as a pro.

Go check it out.

I also am currently using komodo and interested to try switching over to this. It seems lighter and simpler, and the encryption makes more sense to me compared to the Komodo secrets. I'm wondering how hard it would be to migrate from Komodo. One thing I have to figure out is that I switched all my bind mounts to be $DOCKER_DATA and I set the environment variable in my Komodo periphery. I wonder if I have to undo that for doco-cd.

[–] tofu@lemmy.nocturnal.garden 1 points 3 days ago

Not sure if this supports similar variables. I guess generally the migration should be easy as everything is already in the necessary structure but I haven't tried it yet. I only have bindmounts that are in-repo, everything else is docker volumes.

One feature Komodo offers that I'm not yet using is multi-node support. I do have multiple nodes and it would be convenient to have them all configured in one place but IDK if doco-cd has something similar.

@tofu Can't you just use a rootless podman quadlet? Edit: Oh I see, I think it uses gitlab hooks to find out when there are new images available? You can probably point at latest on an image on a gitlab registry anyway and have a quadlet auto update?

[–] tofu@lemmy.nocturnal.garden 6 points 1 week ago

Of course I could use something entirely different, but that's not the point isn't it?
