[ci skip] Add Grafana dashboard for Technitium DNS query logs
Add MySQL datasource and 15-panel dashboard for DNS analytics: queries over time, response codes, top domains/clients, response times, blocked/NxDomain domains. Enable Grafana dashboard sidecar for auto-provisioning dashboards from ConfigMaps.

- **After updating any `.claude/` files**: Always commit them immediately (`git add .claude/ && git commit -m "[ci skip] update claude knowledge"`) to avoid building up unstaged changes.
|
||||
- **Skills available**: Check `.claude/skills/` directory for specialized workflows (e.g., `setup-project.md` for deploying new services)
|
||||
- **CRITICAL: All infrastructure changes must go through Terraform**. NEVER modify cluster resources directly (e.g., via kubectl apply/edit/patch, helm install, docker run). Always make changes in the Terraform `.tf` files and apply with `terraform apply`. The real cluster state must never deviate from what's defined in Terraform — if a manual change is unavoidable (e.g., containerd config on running nodes), document it and ensure the Terraform templates match so future provisioning is consistent. Use `kubectl` only for read-only operations (get, describe, logs) and ephemeral debugging (run --rm, delete stuck pods), never for persistent state changes.
|
||||
- **CRITICAL: NEVER put sensitive data (API keys, passwords, tokens, credentials) into committed files** unless they are encrypted (e.g., via git-crypt). Secrets belong in `terraform.tfvars` (which is git-crypt encrypted) or in the `secrets/` directory. Never hardcode credentials in `.tf` files, scripts, `.claude/` files, or any other unencrypted committed file. Always pass secrets through the Terraform variable chain (`terraform.tfvars` → `main.tf` → module variables).
|
||||
|
||||
## Execution Environment
|
||||
- **File operations**: Read, Edit, Write, Glob, Grep tools
