Chapitre 3. Cluster capabilities
Cluster administrators can use cluster capabilities to enable or disable optional components prior to installation. Cluster administrators can enable cluster capabilities at anytime after installation.
Cluster administrators cannot disable a cluster capability after it is enabled.
3.1. Selecting cluster capabilities
You can select cluster capabilities by following one of the installation methods that include customizing your cluster, such as "Installing a cluster on AWS with customizations" or "Installing a cluster on GCP with customizations".
During a customized installation, you create an install-config.yaml
file that contains the configuration parameters for your cluster. You can use the following configuration parameters to select cluster capabilities:
capabilities: baselineCapabilitySet: v4.11 1 additionalEnabledCapabilities: 2 - CSISnapshot - Console - Storage
- 1
- Defines a baseline set of capabilities to install. Valid values are
None
,vCurrent
andv4.x
. If you selectNone
, all optional capabilities will be disabled. The default value isvCurrent
, which enables all optional capabilities.Notev4.x
refers to any value up to and including the current cluster version. For example, valid values for a OpenShift Container Platform 4.12 cluster arev4.11
andv4.12
. - 2
- Defines a list of capabilities to explicitly enable. These will be enabled in addition to the capabilities specified in
baselineCapabilitySet
.NoteIn this example, the default capability is set to
v4.11
. TheadditionalEnabledCapabilities
field enables additional capabilities over the defaultv4.11
capability set.
The following table describes the baselineCapabilitySet
values.
