Updates

To update the infrastructure, do the following steps:

# Update inputs
nix flake update

# Check builds
nix build

# Push updates to git remote
git add flake.lock
git commit
git push

Deploy updates:

nix develop

# Deploy vms
deploy-qois .#lindberg-nextcloud .#lindberg-build

# Deploy fast physical hosts
deploy-qois .#lindberg

# Deploy slow physical hosts (maybe do individually)
deploy-qois --confirm-timeout 600 --activation-timeout 600 --targets .#fulberg .#tierberg .#stompert .#stompert

After deploying updates, verify that all services run as expected. For kernel updates, it might be required to reboot machines, which can be done in parallel with e.g.:

pssh -l root -H lindberg-nextcloud.backplane.net.qo.is -H lindberg-build.backplane.net.qo.is reboot

Aplication Updates

Some applications have pinned versions to prevent problems due to accidental upgrades.
The version switch has to be done manually by switching the package used.

This includes the modules for:
