In 1.10 ClusterInfo.cluster is now ICluster as opposed to Cluster. How to get Cluster from that?

[shapirov103]

ICluster refactoring was performed to address cluster import. For imported clusters, the type is ICluster and does not have full function support that is available for newly provisioned clusters. For example, cluster authentication is not accessible for imported clusters.

If you are provisioning and maintaining clusters with the blueprints, then you can always rely on the type to be Cluster.

Example checking for the type of cluster:

if(!(clusterInfo.cluster instanceof Cluster)) {
  logger.warn(`Some cluster updates (such as access management) are not supported with imported clusters` );
  return;
}

Example casting to Cluster:

 const eksCluster: Cluster = clusterInfo.cluster;
// do something with eksCluster e.g.:
 eksCluster.awsAuth.addMastersRole(...);

An example of an explicit cast from ICluster to cluster:

import * as eks from 'aws-cdk-lib/aws-eks';
...
const eksCluster = clusterInfo.cluster as eks.Cluster;

Previously, when ClusterInfo.cluster was Cluster I could use addCdk8sChart to apply manifest but now it does nothing. Do you have any idea @shapirov103 ?

[shapirov103]

@vumdao please describe the current behavior when invoking the addCdk8sChart method as it is expect to return the KubernetesManifest. "Does nothing" - returns null? No errors?

If you provide an example (inline or on git), happy to give it a shot. If a failure is coming from CDK, we can raise an issue there.
