+# Gitea K8s Migration Plan (2026-07-13)
+
+Session where the user decided to migrate Gitea from LXC CT108 to RKE2 K8s.
+
+## Current State (CT108)
+
+- Host: proxmox6, LXC container
+- Gitea binary (not Docker), SQLite (4.7 MB)
+- 23 repos (160 MB), 5 orgs/users (dominik, clawdia, codecamp-n, pm-infra, d.schoen)
+- Config: `/etc/gitea/app.ini`, data: `/var/lib/gitea/data/`
+- RAM: ~142 MB RSS, Disk: 1.3 GB / 7.8 GB
+
+## Key Decisions
+
+### 1. Galera over CNPG (user-directed)
+
+User instinctively preferred Galera, then asked for evaluation. After
+comparison, Galera won decisively:
+
+- HA: Galera has 3 nodes + MaxScale. CNPG plan was 1 instance = no HA.
+- Resources: Galera = 0 new. CNPG = 512Mi + 10Gi.
+- MySQL is Gitea's native DB — best-tested combination.
+- SQLite→MySQL migration via Gitea Migration API (no schema conversion).
+
+### 2. Gitea Migration API over manual SQLite dump
+
+The Gitea Migration API (`POST /api/v1/repos/migrate`) eliminates the
+hardest task entirely. One call per repo brings:
+- Git data (clone)
+- Issues + labels + milestones
+- Pull requests
+- Releases
+- Wiki
+
+No `pgloader`, no `sed` on SQLite dumps, no schema conversion.
+
+### 3. External URL: git.schoen.codes
+
+User specified `git.schoen.codes` as the new external URL (not
+`git.familie-schoen.com`).
+
+## Plan Structure (10 Tasks)
+
+1. Create 1Password items (gitea-db, gitea-security)
+2. Create database on Galera via MaxScale VIP
+3. Scaffold iac-homelab directory structure + ArgoCD app manifest
+4. Create ExternalSecrets (DB creds + security tokens)
+5. Create Gitea Helm release values (Galera DB, PVC, Ingress)
+6. Verify K8s Gitea reachable + DB connected
+7. Migrate repos + metadata via Gitea Migration API
+8. DNS cutover (git.schoen.codes → K8s LoadBalancer IP)
+9. Update ArgoCD source URL (chicken-egg cutover)
+10. Shutdown CT108 after 7-day stability window
+
+## Resource Footprint
+
+| Component | CPU req | RAM req | Storage |
+|-----------|---------|---------|---------|
+| Gitea pod | 100m | 256Mi | 10Gi (HDD) |
+| Total | 100m | 256Mi | 10Gi |
+
+Previous (CT108): 1 core, 1 GB RAM, 8 GB disk → K8s footprint smaller.
+
+## iac-homelab Repo Structure
+
+```
+clusters/main/
+├── apps/gitea.yaml          # ArgoCD Application (sync-wave 2)
+├── gitea/
+│   ├── namespace.yaml
+│   ├── external-secrets.yaml # gitea-db + gitea-security (sync-wave 0)
+│   ├── values.yaml           # HelmChart CR (sync-wave 2)
+│   └── README.md
+└── docs/plans/2026-07-13-gitea-k8s-migration.md
+```
+
+## Established Patterns Applied
+
+- ArgoCD App manifest → `clusters/main/apps/{name}.yaml` with sync-waves
+- ExternalSecrets → `external-secrets.io/v1`, ClusterSecretStore `onepassword-store`
+- StorageClasses: `ceph-flash` (SSD) for DB, `ceph-hdd-replica` (HDD) for repo data
+- Traefik ingress with TLS
+- `CreateNamespace=true` in ArgoCD syncOptions
