k-space.ee infrastructure
Kubernetes manifests, Ansible playbooks, and documentation for K-SPACE services.
- Repo is deployed with ArgoCD. For

Tip: Search the repo for kind: xyz for examples.
Supporting services
- Build Git repositories with Woodpecker.
- Passmower: Authz with
kind: OIDCClient(orkind: OIDCMiddlewareClient1). - Traefik2: Expose services with
kind: Service+kind: Ingress(TLS and DNS included).
Additional
- bind: Manage additional DNS records with
kind: DNSEndpoint. - Prometheus: Collect metrics with
kind: PodMonitor(alerts withkind: PrometheusRule). - Slack bots and Kubernetes CLUSTER.md itself.
Network
All nodes are in Infra VLAN 21. Routing is implemented with BGP, all nodes and the router make a full-mesh. Both Serice LB IPs and Pod IPs are advertised to the router. Router does NAT for outbound pod traffic. See the Calico installation for Kube side and Routing / BGP in the router. Static routes for 193.40.103.36/30 have been added in pve nodes to make them communicating with Passmower via Traefik more stable - otherwise packets coming back to the PVE are routed directly via VLAN 21 internal IPs by the worker nodes, breaking TCP.
Databases / -stores:
- KeyDB:
kind: KeydbClaim(replaces Redis3) - Dragonfly:
kind: Dragonfly(replaces Redis3) - Longhorn:
storageClassName: longhorn(filesystem storage) - Mongo4:
kind: MongoDBCommunity(NAS*inventory-mongodb) - Minio S3:
kind: MinioBucketClaimwithclass: dedicated(NAS*:class: external) - MariaDB*: search for
mysql,mariadb5 (replaces MySQL) - Postgres*: hardcoded to harbor/application.yml
* External, hosted directly on nas.k-space.ee

Applications should use OpenID Connect (
kind: OIDCClient) for authentication, whereever possible. If not possible, usekind: OIDCMiddlewareClientclient, which will provide authentication via a Traefik middleware (traefik.ingress.kubernetes.io/router.middlewares: passmower-proxmox@kubernetescrd). Sometimes you might use both for extra security. ↩︎ -
No nginx annotations! Use
kind: Ingressinstead.IngressRouteis not used as it doesn't supportexternal-dnsout of the box. ↩︎ -
Redis has been replaced as redis-operatori couldn't handle itself: didn't reconcile after reboots, master URI was empty, and clients complained about missing masters. ArgoCD still hosts its own Redis. ↩︎
-
Mongo problems: Incompatible with rawfile csi (wiredtiger.wt corrupts), complicated resizing (PVCs from statefulset PVC template). ↩︎
