Etcd is a high availability key-value store, implementing the RAFT
algorithm to deal with failover within the etcd cluster. Popular
in the Docker community as a shared store of small but important
data in a distributed application.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.

sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install etcd, simply use the following command:
