= Sample {gcp-short} failure domain configuration
|
|
|
|
[role="_abstract"]
|
|
To prevent downtime for your application due to the failure of a single {gcp-first} region, you can configure failure domains in the control plane machine set.
|
|
To use failure domains, you configure appropriate values in the `failureDomains` section of the `ControlPlaneMachineSet` custom resource (CR).
|
|
|
|
The control plane machine set concept of a failure domain is analogous to the existing {gcp-short} concept of a link:https://cloud.google.com/compute/docs/regions-zones[_zone_].
|
|
The `ControlPlaneMachineSet` CR spreads control plane machines across more than one failure domain when possible.
|
|
|
|
When configuring {gcp-short} failure domains in the control plane machine set, you must specify the zone name to use.
