  • ViewTube

    Whenever I encounter one of those “What are you self-hosting?” threads, I know I’m about to waste an hour looking at, and often trying out, software I probably don’t really need, and that was the case with this post on the lemmy.world Selfhosted community. The basic idea of ViewTube is that it’s a self-hosted front…

  • Building Docker images for multiple architectures

    My little mdserver app has been a good way for me to start experimenting with the the devops side of things, especially building for Docker. Since I wanted to make the Docker image available for ARM Linux & x86 Linux I had a janky shell script that looked like this: So I’d build two different…

  • Where Do Docker Container Logs Go?

    I’m still loving the Docker “just works” magic, despite their terrible PR skills, but sometimes I start a container, then the docker ps -a shows it exited almost immediately.
