Docker Dev Environments

• if glyphs aren't rendering in LunarVim, check out nerd fonts

  • needs to be installed on host machine. try running the following commands:

    git clone --filter=blob:none --sparse [e-mail]:ryanoasis/nerd-fonts
    cd nerd-fonts
    git sparse-checkout add patched-fonts/DejaVuSansMono
    ./install DejaVuSansMono
    

  • alternatively, check out this repo for installing nerd fonts

• if typing ctrl-p in the container (e.g. to scroll through command line history) is behaving abnormally, add the following to $HOME/.docker/config.json (on the host machine)

    {
      "detachKeys": "ctrl-q,ctrl-q"
    }
  

  • if this doesn't work, check if $DOCKER_CONFIG is set to something other than $HOME/.docker (on the host machine)
  • additionally, sudo can change the value of $HOME (on the host machine)
    • one option is to add Defaults env_keep+="HOME" to /etc/sudoers using visudo (on the host machine)

Notes

• Would the problems this is trying to solve be better addressed with custom package groups?
  • Problems with this approach:
    • Potentially unnecessary use of space.
      • E.g. the man pages are excluded in the base archlinux docker image. Sharing the man pages directory would break encapsulation because man pages for packages installed inside the container would be installed on the host machine. If they aren't shared then that is a bunch of duplicated man pages.
      • Could this be solved with a functional paradigm OS? Could the notion of immutability be applied here somehow to share files safely? So they could be logically separate but share the underlying resource (e.g. on disk). Everything on disk is read or delete only and only gets deleted when nothing points to them?
  • Brainstorm:
    • Config file somewhere that has a list of languages that I want to be able to work on.
    • All related packages get installed automatically.
      • I maintain a list of all related packages? That's what I'm doing in this docker approach.
    • All relavant config (e.g. nvim config) gets set up.
      • This would probably work best if my config is broken up into more granular files. I'm already doing that. I just need a merging strategy.
