Felix Wolf 85b8fec6b3 feat: replace secret-init Jobs with mittwald operator + cert-manager
Migrate ~180 LOC of openssl/kubectl init Jobs to declarative Secret
manifests reconciled by mittwald/kubernetes-secret-generator (random
strings, SSH keypair) and cert-manager Certificates (RSA private key +
self-signed CA chain). mittwald only fills empty fields, so existing
populated Secrets keep their current values across the migration.

Changes:

- New prototype kubernetes-secret-generator (chart 3.4.1, mittwald helm
  repo). Cluster-wide informer reconciler, no webhook -> cold-bootstrap
  safe via ArgoCD retries.
- New cert-manager selfsigned ClusterIssuer (in-cluster trust root).
  letsencrypt remains for public-DNS endpoints.
- forgejo: admin-secret Job replaced with a mittwald-annotated Secret
  (hex-encoded 24-char password). Deploy-key Job split: mittwald
  ssh-keypair Secret + slim Job that uploads pubkey to Forgejo and
  copies privkey into the argocd repo Secret.
- ocis: 13 Secrets / 16 random fields now mittwald-managed (UUIDs
  replaced with opaque random hex; ocis treats user-id as opaque). IDP
  RSA signing key, LDAP self-signed CA, and LDAP server cert produced
  by cert-manager. Per-Deployment ytt overlay remaps volume key paths
  (tls.crt -> ldap-ca.crt, tls.key -> private-key.pem, etc.) since the
  ocis chart mounts Secrets raw without items support. Old multi-secret
  s3-secret-job replaced with a slim external-secret precheck Job that
  only validates pre-created Hetzner S3/Storage Box credentials.
- Application sync-wave -10 on cert-manager and kubernetes-secret-
  generator so they install before consumers. ArgoCD selfHeal handles
  any residual races.

CLAUDE.md: remove the "all namespaces use privileged PodSecurity"
convention. Existing namespaces still carry the label and will be
audited separately.

Felix Wolf 1122c3f0e2 feat: Implement S3 to Storage Box backup
Introduces a daily Kubernetes CronJob that utilizes rclone to perform compressed backups of oCIS S3 data to a Hetzner Storage Box via SFTP.

This new backup mechanism requires the manual creation of an 'ocis-storagebox-credentials' secret, which holds the Storage Box host, user, and SSH private key. A check is added to the secret initialization job to ensure this essential external secret exists.

Felix Wolf 4e48df73d3 feat(ocis): Transition to oCIS and enhance deployment
Removes the full Nextcloud stack (PostgreSQL/CNPG, Valkey, Caddy) and
  deploys oCIS at drive.tr1ceracop.de. oCIS is self-contained — no
  external database or cache needed.

  Key design decisions:
  - S3ng storage backend on Hetzner Object Storage (ocis-tr1ceracop)
  - Chart fetched via vendir git source (not published to a Helm repo)
  - All secrets generated in-cluster via PreSync init Job (never in git)
  - Memory requests on all pods to prevent node overcommit
  - Persistence on local-path for metadata (idm, nats, search, storage)

Felix Wolf c7bfd4953c feat: Wire ArgoCD to Forgejo for GitOps management
Configure myks with global repoURL pointing to Forgejo, in-cluster
destination, and disabled placeholder cluster Secret. Implement App of
Apps pattern with a root Application that syncs all child apps.

Add argocd-deploy-key-init Job that generates an ed25519 SSH keypair,
registers it as a deploy key via Forgejo API, and creates the ArgoCD
repository secret with insecure host key verification (avoids
chicken-and-egg with ArgoCD managing its own known hosts ConfigMap).

Additional changes:
- Ignore /status field diffs globally (K8s 1.32 compat)
- Add Replace=true sync option on Jobs (immutable resource compat)
- Switch job images from bitnami/kubectl to alpine/k8s
- Update CLAUDE.md with ArgoCD status and no-bitnami rule

Felix Wolf 6f717a602f feat: Initial setup of GitOps-managed Kubernetes cluster
Configures `myks` for Helm chart rendering with `ytt` overlays to manage cluster applications.
Defines prototypes and environment-specific configurations for core applications including ArgoCD, Traefik, Cert-Manager, and Forgejo.
Adds comprehensive documentation covering cluster setup, GitOps structure, and development environment.
Integrates `direnv` for environment variable management, `gitignore` for file exclusion, and `sops` for secret encryption.
Includes rendered Kubernetes manifests and ArgoCD application resources for initial deployment.
