Some days it just blows my mind how some pieces of software have gained so much traction, with so little in the way of support for some common use cases.
Today; #Docker running on an IPv6 only host.
Who thought assigning IPv4 addresses to containers running on an IPv6 only host was a sensible default that is so difficult to override?

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.

First real test of the new cluster: encoding AV1 video. I created three Sisyphus encoding workers and decided to run some Blurays across all the servers. Wrote some Ansible to build the encoding workers because it's a pain in the ass, but right now I'm working through the first 3 videos in a queue of 12. Also, these are so much more efficient...

Resolving Missing Memory Stats in Docker Stats on Raspberry Pi
Running Docker containers on your Raspberry Pi can be a great way to explore different software and services. However, encountering issues with retrieving memory usage information using docker stats can be frustrating. In this blog post will dive into the common reasons behind missing memory stats and guide you through the troubleshooting steps to resolve them.

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.

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.

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 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.

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.

What I actually would have liked Apple to make is macOS containers. Don’t see what this gives over Colima/docker desktop.

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.

Does anyone know how to do this?
