Note the following:

  • Containerd is the supported runtime environment for Kubernetes. Crio is the supported runtime environment for OpenShift.

  • UPI, IPI, or any other customized solution is supported for installation on OCP. Deployment environment can be Bare Metal or virtual (VMware ESXi).

  • The configuration comprises a network of master nodes, worker nodes, and a bastion node. CLI access from the bastion node to the master nodes and the worker nodes must be enabled.

  • You can perform a rolling upgrade of OCP or Kubernetes platforms. Before upgrading, refer to the supported platform and kernel versions table. Ensure that you upgrade to an InfoScale-supported version. Refer to OpenShift or Kubernetes documentation for steps to upgrade. For redundant storage and applications, there is no downtime during an upgrade.
