[Raspberry Pi] HA K8s Pi Cluster (II)
In my journey to establish a Highly Available Kubernetes Pi Cluster, I've successfully configured the cluster following an external etcd setup. The process involves installing Docker, setting up the Docker daemon, and installing kubeadm. Initializing Kubernetes Master Nodes, preparing certificates, and configuring Calico for networking are key steps. Troubleshooting tips include addressing refused connections and certificate expiration. To rejoin a faulty node, cordoning, draining, and generating new keys are essential. Now, I proudly own a fully operational Highly Available Kubernetes Pi Cluster.

[Raspberry Pi] HA K8s Pi Cluster (I)
In this special guide, I celebrate Singapore's 55th National Day by setting up a Highly Available Kubernetes Pi Cluster using 2x Raspberry Pi Model B 8GB. With a total setup time of 25 minutes, I configure an external etcd key-value store, laying the foundation for high availability. I detail OS preparation, creating a virtual IP with Keepalived, generating certificates for etcd, and setting up etcd on each master node. Troubleshooting tips are provided, including addressing cluster ID mismatches and replacing faulty members. Stay tuned for the next article covering the continuation of the HA configuration.
