Simplify Networking in Kubernetes with Consul and Wireguard
summary
Runs a Wireguard server in-cluster exposed publicly and configures clients to use the cluster DNS so local machines resolve ClusterIP and .consul names. Uses a Place1 wg-access Helm chart, forwards UDP port 51820, and points DNS to CoreDNS at 10.96.0.10 while forwarding .consul requests to Consul’s DNS. Demo connects a laptop to a five-node Raspberry Pi cluster, curls pod IPs, and retrieves Vault secrets via Vault accessed through .consul DNS, showing layer‑3 routing and successful troubleshooting from outside the cluster.
