Red Hat Advanced Cluster Management (RHACM) enables Open Cluster Management policy driven governance of an entire fleet of Kubernetes clusters. Associating policies with the appropriate clusters is a very flexible operation and requires understanding resources like Placements and ManagedClusterSetBindings. So let’s get familiar!
If you find yourself frequently rebuilding OpenShift clusters and potentially reusing cluster names, you may find it challanging to manage the credentials consistently and securely. Here is a solution using 1Password.
The Ceph Toolbox is not recommended or supported for use with OpenShift Data Foundation, but sometimes you want a client to troubleshoot with anyway.
OpenShift creates a number of Certificate Authorities to sign TLS certificates which secure functions including load balancing of the API and Ingress services.
Recent versions of openshift-install will place all the CA certificates in the generated auth/kubeconfig file.
Here is how to extract and split those certificates into individual files which eases the process of trusting them particularly on a Mac.
