    Learn S6-Overlay that allows to have one docker container for multiple processes... make immich docker compose not a two page 8 containers long? But just one clean container with healthcheck. Convince the devs to switch to it.

  • Alpine Linux is reducing dependencies on Busybox
    3 projects | news.ycombinator.com | 3 Aug 2022
    Used s6-overlay[1] to start a lot daemons in a docker-image for demo purposes - postgres, tomcat, mysql, php-fpm, apache (don't ask why ;) - s6 worked really well and was reliable and stable - I enjoyed it very much. It was also possible to reliable pass SIGTERM to the daemons in the image for clean shutdown and it was easily possible to configure logging to stdout with a prefix. Modelling dependencies (waiting on database before starting app etc.pp) is possible via shell-scripts. It's super flexible but out of the box it's more like a collection of powerful tools not a complete package - but that's good. It's in the tradition of djb daemontools and is very unix - as in doesn't talk a lot and you better know how each part works but - and that's really cool - it's modular and simple and once you get a grip on it you can easily reason about it. systemd takes a completely different approach and also solves a kind of differnt problem - this is like small pieces of lego that compose well instead of one big chunk of glib/dbus/glibc only c-code.

    If you *really* want to make your own containers with PUID/PGID support checkout "S6-overlay" and the linuxserver "baseimage". Somewhere in the startup they end up running:

  • Starting a service in Dockerfile

    Not sure about unbound or what have inside the pihole base image, you may try to run the service in foreground or use some tiny init service for that container (I just learnt that s6 may work for that, but you must be aware how it should be used)

  • Is it viable to use containers as a turnaround virtual machine?
    3 projects | /r/docker | 2 Feb 2022
    Any idea where to get started? I've tried using a few repos on github as a point of reference to build my own kali + vnc image, but they're all severely outdated. I spent most of yesterday reverse engineering a dockefile that uses s6 but it was running version 1.2 something and the current version is like 3.0.02 iirc.
