If you are using "docker:latest" in your CI pipeline, you may find your builds broken with a weird "failed to find target default" error.
In that case, switching to "docker:28.3.1" will fit this.

For anyone who wants to self-host their catalog of book video game or movie collections, Koillection is a good open-source option.
It can also be installed using Docker, which can speed up the setup process.
I've only been using this tool for a couple of days, and it looks promising. The only thing that doesn't seem very intuitive at the moment is the scraping system, although its developer has commented on GitHub that they are working on it.

@… Makes sense, I’m glad to hear it’s more stable now.
I use the Docker image because I am lazy and because Rails is a bag of cats, which definitely makes upgrades easier, as it’s just swapping out a version number.

Duplicati is in the process of saving my ass again, but their backup restores are extremely slow.
Their web interface is neat and the handling is more or less intuitive, but I think I'm going back to the rsync & cron script formula.
It's what I've done on my server all my life until I installed Docker, but in this case I'm going back to my simple origins.

Just published v0.14.0 of helmfile-nix, a wrapper around helmfile in go to allow you to use the #nix language to manage helm releases on kubernetes rather than yaml go templating. This release adds functionality to also write ad-hoc helm charts directly in nix. https://github.com/reMarkable/helmfile-nix/releases/tag/v0.14.0 we provide binaries as well as a docker image with static nix based on alpine. You can also use it as a flake.

Does anyone have experience with running docker images of other Linux distros in GitHub Actions CI?
Use case is validating that things build and run under e.g. Fedora or Arch given an outer Ubuntu system. It won't be perfect because you're still running the Ubuntu kernel but should be good enough to find obvious build problems, produce usable nightly builds, etc.

The minimalist approach is super interesting (static, no libc even). They claim you can launch a container and have a shell in “a few hundred milliseconds” and I definitely remember waiting longer than that for `ruby` to start, back when I was doing a lot of Vagrant work.

Don't know why it took me so long to get hip to LXC containers. Extremely convenient to use and with none of the docker brainworms.

Docker under Siege: Securing Containers in the Modern Era
Containerization, driven by Docker, has transformed application development and deployment by enhancing efficiency and scalability. However, the rapid adoption of container technologies introduces significant security challenges that require careful management. This paper investigates key areas of container security, including runtime protection, network safeguards, configuration best practices, supply chain security, and comprehensive monitoring and logging solutions. We identify common vulner…

If you use Duplicati on your Linux server via Docker to perform backups to an external USB drive, this must be mounted before the container starts up. Otherwise, Duplicati will throw an error ("missing files") when it tries to perform the backup because it cannot verify the files on the external drive, even though it tells you that it can detect that external drive.
The quickest solution in this case is to restart the Duplicati container.

Does anyone know how to do this?

4. Similar to number 1, but I just want a button in the web UI which can update the app. It's probably a security thing or something, but this is literally the first time I do all this docker RPi self-hosting stuff... 😭 I think a huge chunk of my issues would go away if I could just manage everything (updates, song additions, auto file tagging) in the Navidrome web UI instead of all of these other apps.

I don't own a lot of computers anymore that still have x86 chips in them. I'm going to pull my backup server out of my parents house and try to run it on that. This might be a fairly long process.
I should see if I can recover the docker containers that were running on it and put those onto my Mac Mini for the time being. I was incredibly good about keeping 3/2/1 backups.

#til about docker contexts.
Turns out docker already has facilities for securely running commands on a remote host via tcp socket.
Wonder how this fits in with platforms like komodo or portainer that have their own core agent model for managing remote servers 🤔

@… Seems legit. I personally use Docker, because I am used to it (and I do want some containment), but I won’t claim it’s great. I was looking into Incus but… eh. I’d rather use systemd-nspawn.
