== Cluster backup policy
|
|
|
|
[IMPORTANT]
|
|
====
|
|
It is critical that customers have a backup plan for their applications and application data.
|
|
====
|
|
Application and application data backups are not a part of the {product-title} service.
|
|
All Kubernetes objects in each {product-title} cluster are backed up to facilitate a prompt recovery in the unlikely event that a cluster becomes irreparably inoperable.
|
|
|
|
The backups are stored in a secure object storage (Multi-AZ) bucket in the same account as the cluster.
|
|
Node root volumes are not backed up because Red Hat Enterprise Linux CoreOS is fully managed by the {OCP} cluster and no stateful data should be stored on the root volume of a node.
|
|
|
|
The following table shows the frequency of backups:

Node autoscaling is not available on {product-title} at this time.
|
|
|
|
[id="daemon-sets_{context}"]
|
|
== Daemon sets
|
|
Customers may create and run DaemonSets on {product-title}. In order to restrict DaemonSets to only running on worker nodes, use the following nodeSelector:
|
|
|
|
[source,yaml]
|
|
----
|
|
...
|
|
spec:
|
|
nodeSelector:
|
|

|
[id="multi-availability-zones_{context}"]
|
|
== Multiple availability zone
|
|
In a multiple availability zone cluster, control nodes are distributed across availability zones and at least three worker nodes are required in each availability zone.
|
|
|
|
[id="node-labels_{context}"]
|
|
== Node labels
|
|
Custom node labels are created by Red Hat during node creation and cannot be changed on {product-title} clusters at this time.
|
|
|
|
[id="openshift-version_{context}"]
|
|
== OpenShift version
|
|
{product-title} is run as a service and is kept up to date with the latest {OCP} version.
|
|
|
|
[id="upgrades_{context}"]
|
|
== Upgrades
|
|
Refer to link:https://access.redhat.com/support/policy/updates/openshift/dedicated[{product-title} Life Cycle] for more information on the upgrade policy and procedures.

|
[id="operating-system_{context}"]
|
|
== Operating system
|
|
{product-title} runs on OpenShift 4 and uses Red Hat Enterprise Linux CoreOS as the operating system for all control plane and worker nodes.
|
|
|
|
[id="kubernetes-operator-support_{context}"]
|
|
== Kubernetes Operator support
|
|
All Operators listed in the OperatorHub marketplace should be available for installation. Operators installed from OperatorHub, including Red Hat Operators, are not SRE managed as part of the {product-title} service. Refer to the link:https://access.redhat.com/solutions/4807821[Red Hat Customer Portal] for more information on the supportability of a given Operator.
