Erich Blume 7a1875936c Switch git hooks from pre-commit to prek (#276)
## Summary

- Replace pre-commit with [prek](https://github.com/j178/prek), a faster Rust-native drop-in alternative
- Migrate config from `.pre-commit-config.yaml` (YAML) to `prek.toml` (TOML)
- Add new built-in checks: case conflicts, private key detection, executable shebangs
- Install prek via mise native registry (`aqua:j178/prek`) instead of pipx
- Update all doc references across README, contributing guide, and how-to docs

## Notes

- `check-yaml` still uses the remote `pre-commit-hooks` repo because prek's builtin fast path doesn't support `--unsafe` yet (needed for Ansible custom YAML tags)
- All existing custom hooks (docs validation, container version check, mikado invariant, workflow validation) work unchanged
- Tested: all hooks pass on clean tree, deliberate doc link breakage is caught

## Test plan

- [x] `prek run --all-files` passes all checks
- [x] Broken wiki-link correctly caught by `docs-check-links`
- [x] taplo-format auto-fixes TOML formatting on commit
- [x] commit-msg hook (mikado invariant) fires correctly

Your First Contribution

Audiences: Contributor

This tutorial walks through making your first contribution to BluemeOps - from understanding the codebase to submitting a pull request.

Prerequisites

Before contributing, you'll need:

Tooling Setup

The repo includes a Brewfile and mise.toml for easy setup, but these are optional - install the tools however you prefer.

Required Tools

  • tea - Gitea/Forgejo CLI for creating PRs
  • argocd - ArgoCD CLI for deployments
  • prek - Git hooks for validation

Using Brewfile (Optional)

brew bundle  # installs tea, argocd, mise, etc.

Using Mise (Optional)

Mise manages language toolchains and runs tasks:

mise install  # installs Python, Node.js, etc. from mise.toml

Git Hooks (prek)

Git hooks validate changes on git commit:

prek install
prek run --all-files  # verify setup

All hooks should pass on a fresh clone.

Understanding the Codebase

BlumeOps manages infrastructure through three main systems:

System Directory What It Manages
Ansible ansible/ Services running directly on indri
ArgoCD argocd/ Kubernetes services in the cluster
Pulumi pulumi/ [[tailscale

Most contributions involve either Ansible roles or ArgoCD manifests.

The Contribution Workflow

1. Clone and Branch

git clone ssh://git@forge.ops.eblu.me:2222/eblume/blumeops.git
cd blumeops
git checkout -b feature/your-change-name

2. Make Your Changes

Depending on what you're changing:

For Kubernetes services:

  • Edit manifests in argocd/manifests/<service>/
  • Or create new Application in argocd/apps/
  • For new apps, set targetRevision to your feature branch for testing
  • For existing apps, you'll need to temporarily change the revision via argocd app set

For Indri services:

  • Edit or create roles in ansible/roles/
  • Update ansible/playbooks/indri.yml if adding a role

For documentation:

  • Edit files in docs/
  • Add changelog fragment (see below)

3. Add a Changelog Fragment

For user-visible changes:

echo "Description of your change" > docs/changelog.d/your-branch.feature.md

Fragment types (file suffix):

  • .feature.md - New functionality
  • .bugfix.md - Bug fixes
  • .infra.md - Infrastructure changes
  • .doc.md - Documentation
  • .misc.md - Other

4. Test Your Changes

Before pushing, always test:

For Kubernetes changes:

# Preview what will change
argocd app diff <service>

For DNS changes:

mise run dns-preview

5. Commit and Push

git add <files>
git commit -m "Brief description of change"
git push -u origin feature/your-change-name

6. Create a Pull Request

tea pr create --title "Your PR Title" --description "$(cat <<'EOF'
## Summary
- What you changed
- Why you changed it

## Deployment and Testing
- [ ] Tested locally / dry run
- [ ] Ready for ArgoCD sync / Ansible apply

EOF
)"

7. Wait for Review

Erich will review your PR and may leave comments. Check for feedback:

mise run pr-comments <pr_number>

Address each comment, then Erich will:

  1. Approve the changes
  2. Deploy them (you don't need to do this)
  3. Merge the PR

A simple first contribution - adding a service to the Homepage dashboard (go.ops.eblu.me):

  1. Find the service's Ingress in argocd/manifests/<service>/
  2. Add homepage annotations:
annotations:
  gethomepage.dev/enabled: "true"
  gethomepage.dev/name: "Service Name"
  gethomepage.dev/group: "Apps"
  gethomepage.dev/icon: "service.png"
  1. Create PR and wait for sync
