You need to have ETCD properly configured before you install Kubernetes as
Kubernetes uses ETCd to distribute its configuration.

There are two ways to setup ETCd cluster. The first one requires to use
some hub which will be a coordination point between ETCd nodes. The second
one is manual way when you add each ETCd member one by one providing
initialization configuration string as an option on each member. Each time
you add an ETCd member this init string will be changed.

Here are bash scripts which are used in Kubernetes cluster automation in

the sequence or ETCd is the following:
on ETCd master (first VM): master-etcd-setup.sh <cluster_name> <IP addr of
--==Adding an ETCd memeber ==-
1) On master: master-add-member.sh <cluster_name> <ip addr of a member>
2) take the init string generated after script execution
3) On new member: member-etcd-setup.sh <cluster_name> <ip addr of the
member> <initial config from the previous step>

Just take a look on the scripts and you will figure out how to setup a
