Install kube-vip for HA3. Protect etcd with TLS, Firewall and Encryption. Since etcd stores the state of the cluster and its secrets, it is a sensitive resource and an attractive target for attackers. If unauthorized users gain access to etcd they can take over the entire cluster. Read access is also dangerous because malicious users can use it to elevate privileges.Regular etcd Backups. Since etcd stores the state of the cluster, it is recommended that you regularly backup etcd data, and store backups on another host. Here are three ways to backup etcd clusters: Taking a snapshot using the etcdctl snapshot save command; Directly copying the data from the member/snap/db directoryThe other two (Etcd and Container Engine) components are two external dependencies that are not strictly part of the Kubernetes project, but which Kubernetes needs in order to work: Etcd is a third-party database used by the Kubernetes project. Don't worry; you won't have to master it in order to use Kubernetes.Finally, we use the script included in the demo, etcd_exec_watch.sh, to invoke an external handler, script.sh, every time there is an update to the list of registered services (that is, a change to etcd keys).
