Multi Master

Multi Master

Support for multi master clusters exists for clusters >=1.17.x.

Check for an existing public cluster template with this feature - suffix multi.

For custom cluster templates, make sure you pass this extra flag:

openstack coe cluster template create myclustertemplate
    --master-lb-enabled ...

The number of masters should ideally be odd (3, 5 or 7), since it is backed by an etcd cluster.

Work is ongoing to set this at cluster creation, which will simplify the setup significantly.
