The ansible script in this directory can be used to deploy a fully functioning 3 node ‘etcd3’ cluster to existing servers or VMs with host persistent storage.

The inventory file inv.yml should be structured as follows:

server1 IP=
server2 IP=
server3 IP=

Ensure that the nodes group is used and that the IP attribute is defined

This installation method assumes you have root ssh keys installed on all the servers in the inventory file.


The current/default version of ‘etcd3’ installed is "3.2.7". For other version of etcd3 to be installed, update the etcd_version variable in the etcd3.yml file.

To install ‘etcd3’ on all servers, run the following command:

ansible-playbook -i inv.yml etcd3.yml
