How do I install ETCD

How can I also connect to ETCD?

Connect with etcd

How do you use ETCD with Kubernetes, other than the above? Kubernetes uses etcd to store key-value data. It stores the configuration for the Kubernetes Cluster in etcd. It also stores the current state and desired state of each system in etcd. The watch function of etcd allows it to monitor any changes to these two things.

What is the ETCD?

etcd is a strong consistent distributed key-value store. It provides a reliable way for data to be stored that can be accessed by a cluster of machines or distributed system. It can gracefully handle leader elections during network partitions, and can tolerate machine failure even at the leader node.

Do Kubernetes require ETCD?

Actually, etcd is Kubernetes' primary datastore. It stores and replicates all Kubernetes cluster states. It is tedious work to bootstrapping, manage quorum, reconfigure cluster membership, create backups, handle disaster recovery, monitor critical events, and other tasks that require etcd-specific expertise.
