Among other things, this repository contains NixOS configurations for Fedimint's self-hosted github runners.
Runners need to be periodically updated, which means updating nixpkgs/NixOS
to a newer version, deploying new version to corresonding hosts and then
committing updates to the github repository.
Use this workflow when asked to update the self-hosted GitHub runners for this repository.
Fetch master branch updates from git and rebase on top, so runner updates start from the latest repository state.
Update Nix flake inputs:
nix flake update
Do not run just apply-all-runners: it can take too long as a single command and is harder to recover from.
Instead, inspect the repository justfile, find the uncommented just apply-runner ... lines in the
apply-all-runners recipe, and apply each runner individually with a long timeout.
At the time of writing, the recipe expands to:
just apply-runner "01"
just apply-runner "02"
just apply-runner "04"
just apply-runner "arm-01"
Use the current justfile as the source of truth if it differs from this list. Each just apply-runner ...
command can take a long time, so run it with a very long shell/tool timeout, e.g. 30 minutes or longer per runner.
If a runner fails, report exactly which runner failed and continue only if the failure is clearly unrelated and safe.
