Add a cluster to centrally manage installs and configurations within Lifecycle
Manager for DataStax Enterprise clusters.
Add a cluster to centrally manage installs and configurations within Lifecycle
Manager for DataStax Enterprise clusters. By default, all datacenters within a
cluster inherit the configuration profile from the cluster level, unless overridden
when creating the datacenter model. By default, all nodes within a datacenter
inherit the configuration profile from the datacenter level, unless overridden when
creating the node models. SSH settings can also be inherited or overridden at the
datacenter or node levels. Repositories are only specified at the cluster level and
are inherited by datacenters and nodes.
Procedure
-
Click Clusters from the Lifecycle Manager navigation
menu. If you do not have any clusters yet, click the adding a cluster link on
the Getting Started page.
-
Click the + (plus) sign above the Clusters pane.
The Add Cluster dialog appears.
- Required:
Enter a name for the cluster. The name reflects the cluster name in both
DataStax Enterprise and Lifecycle Manager.
The cluster name cannot be edited after clicking Save because LCM populates
the cluster_name
field in
cassandra.yaml with the entered value.
-
Select predefined SSH Credentials to use for accessing
the machines that nodes reside on.
- Optional:
Specify a SSH Management Port to override the default of 22.
-
Select a predefined Config Profile to apply at the
cluster level. If config profiles are not defined for datacenter or node levels,
those levels inherit from the cluster.
- Optional:
Enter a descriptive comment about the cluster. Example: Dev cluster, or Prod
cluster.
-
Select a predefined Repository from which to access
DataStax Enterprise install packages. Datacenters and nodes inherit the
repository from the cluster level. Defining a repository for the datacenter or
node level is not necessary.
-
Click Save.
The newly defined cluster displays in the Clusters pane. Click the
cluster title to view its details. The Datacenters pane becomes
visible.
What's next
- Add another cluster. Repeat this procedure as necessary.
- Add datacenters to the
cluster.
- Add nodes to the
datacenters.
- Run an installation job. After Lifecycle
Manager successfully creates a cluster during an install job, LCM automatically
adds the cluster to the OpsCenter workspace for monitoring and management.
