## Summary
- Deploys Kanidm 1.10.3 (ghcr.io/kanidm/server:1.10.3) as a 2-replica
StatefulSet with built-in replication enabled
- Domain: auth.unkin.net (primary WebAuthn origin); au.auth.unkin.net
is an additional hostname for this au-syd1 instance
- TLS: cert-manager Certificate (vault-issuer) covering auth.unkin.net,
au.auth.unkin.net, kanidm.k8s.syd1.au.unkin.net, and internal
headless pod DNS names — Kanidm terminates TLS itself (passthrough)
- Gateway: TLS passthrough on port 443 via TLSRoute; HTTP on port 80
redirects to HTTPS; external-dns creates kanidm.k8s.syd1.au.unkin.net
(not used in server.toml; canonical origin is auth.unkin.net only)
- Replication: init container generates per-pod server.toml with the
correct repl:// origin (kanidm-{N}.kanidm-headless.kanidm.svc);
populate kanidm-repl-peers ConfigMap post-deployment after running
`kanidmd show-replication-certificate` on each pod
- Storage: 10Gi cephrbd-fast-delete PVC per pod via volumeClaimTemplates
- Security: runAsUser/runAsGroup 1000, runAsNonRoot, no privilege
escalation, allowPrivilegeEscalation=false
- ArgoCD: platform ApplicationSet and Project updated for kanidm namespace
## Requires
- PR benvin/kanidm-artifactapi (add ^kanidm/ to ghcr immutable patterns)
to be merged first so artifactapi can cache ghcr.io/kanidm/server
## Post-deployment steps
1. Wait for both pods to reach Running state
2. Exchange replication certificates between pods:
kubectl exec -n kanidm kanidm-0 -- kanidmd show-replication-certificate
kubectl exec -n kanidm kanidm-1 -- kanidmd show-replication-certificate
3. Edit kanidm-repl-peers ConfigMap with both nodes' certs
(see template in configmap.yaml comments)
4. kubectl rollout restart statefulset/kanidm -n kanidm
## Test plan
- [x] Sandbox tested in sandbox-kanidm: all 11 resources server dry-run OK
- [ ] After merge: ArgoCD syncs kanidm namespace
- [ ] Verify auth.unkin.net and au.auth.unkin.net reachable via Gateway
- [ ] Verify kanidm.k8s.syd1.au.unkin.net DNS record created by external-dns
- [ ] Complete replication cert exchange and verify replication active
