I have installed rootless docker on ubuntu 20.04 [https://docs.docker.com/engine/security/rootless/][1]

I have download vscodium appimage from [https://github.com/VSCodium/vscodium/releases/download/1.66.0/VSCodium-1.66.0-1648720116.glibc2.17-x86_64.AppImage][1]

  1. i have shared host directory containing this Appimage with rootless docker container. But it doesn't run. When I manually install(apt-get install) any GUI package(ex. firefox) inside the container it runs successfully.

  2. output of the command: docker-compose up vscodium

    Creating vscodium ... done
    Attaching to vscodium
    vscodium | codium: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory
    vscodium exited with code 127

A few notes on running AppImages insude docker:

  • AppImages require fuse to run which is usually not available/usable on docker
  • Extract the AppImage contents and mount that folder on your docker
  • missing libnss3.so, you will have to install this on the host system. If it doesn't work you will have to report it to the AppImage author to for them to include it in the bundle.
