Add k3s, 1Password Connect, and systemd nix-container-builder to ringtail (#209) ## Summary Extends ringtail from a desktop/gaming NixOS box into an infrastructure node with a k3s cluster, secrets management, and a Forgejo Actions runner for building containers with Nix. ### K3s cluster - Single-node k3s with Traefik/ServiceLB/metrics-server disabled (minimal footprint) - TLS SAN set to `ringtail.tail8d86e.ts.net` so ArgoCD on indri can manage it via Tailscale - Containerd registry mirrors pull through Zot on indri (`k3s-registries.yaml`) - Tailscale interface added to `trustedInterfaces` for cross-node ArgoCD access - `kubectl` added to system packages ### 1Password Connect + External Secrets Operator - Four new ArgoCD apps targeting `k3s-ringtail`: `1password-connect-ringtail`, `external-secrets-crds-ringtail`, `external-secrets-ringtail`, `external-secrets-config-ringtail` - Reuses the same Helm charts/values as indri, just pointed at ringtail's k3s API server - Bootstrap secrets (`op-credentials`, `onepassword-token`) provisioned by Ansible pre_tasks via `op read`, then applied to the `1password` namespace in post_tasks ### Systemd Forgejo Actions runner - Native `services.gitea-actions-runner` with `forgejo-runner` package — no DinD, no k8s pod, runs directly on the NixOS host - Label `nix-container-builder:host` — jobs execute on the host with `nix`, `skopeo`, `nodejs`, etc. in PATH - Registration token fetched from 1Password (`Forgejo Secrets/runner_reg`) by Ansible and written to `/etc/forgejo-runner/token.env` - Runner's dynamic user (`gitea-runner`) added to `nix.settings.trusted-users` for nix daemon access ### Nix container build workflow - New `.forgejo/workflows/build-container-nix.yaml` triggers on `*-nix-v[0-9]*` tags (e.g. `nettest-nix-v1.0.0`) - Builds with `nix build -f containers/<name>/default.nix`, pushes to Zot via `skopeo copy` - Existing Dockerfile workflow guarded with `if: !contains(github.ref_name, '-nix-v')` to avoid double-triggering ### Mise task updates - `container-tag-and-release` auto-detects `default.nix` vs `Dockerfile` and uses the appropriate tag format (`-nix-v` vs `-v`) - `container-list` shows build type indicator (`[nix]` / `[dockerfile]`) ## Post-merge 1. `mise run provision-ringtail` — deploys k3s token, runner token, NixOS rebuild 2. Register k3s cluster in ArgoCD (first time only): ```fish ssh ringtail 'sudo cat /etc/rancher/k3s/k3s.yaml' | \ sed 's|127.0.0.1|ringtail.tail8d86e.ts.net|' > /tmp/k3s-ringtail.yaml set -x KUBECONFIG /tmp/k3s-ringtail.yaml argocd cluster add default --name k3s-ringtail 3. Sync ArgoCD apps in order: 1password-connect-ringtail -> external-secrets-crds-ringtail -> external-secrets-ringtail -> external-secrets-config-ringtail 4. Verify runner: ssh ringtail 'systemctl status gitea-runner-nix-container-builder' 5. Check Forgejo admin panel for ringtail-nix-builder runner online 6. Test: create containers/<name>/default.nix, tag with <name>-nix-v0.1.0 Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/209
