Addons¶

Cluster infrastructure components — the platform layer that everything else depends on.

ArgoCD¶

GitOps continuous delivery controller. Watches the master branch and automatically syncs the cluster to match the declared state in Git.

Automates TLS certificate issuance and renewal via Let's Encrypt (DNS-01 challenge through Cloudflare).

Bare-metal load balancer. Assigns external IPs to LoadBalancer services using L2 ARP announcements on the LAN.

Distributed block storage for Kubernetes. Provides persistent volumes backed by cluster nodes, with built-in replication and snapshots.

Syncs Secrets and ConfigMaps across namespaces. Used to replicate TLS certificates issued in one namespace to others that need them.
