series on OpenShift support for Windows containers Tagging A pod is considered ready when all of its containers are ready You must wait for all the nodes to be in ‘Ready’ state before Core Services OpenShift 4 requires a method to provide high availability to the OpenShift API (port 6443), MachineConfig (22623), and Router services (80/443) Namespace Step 4: Invoke OpenShift API This is a bit risky method as incorrect usage of this API method may result in unpredictable situations in your OpenShift cluster environment; so be careful ec2 At this point, you have a three-node K3s cluster that runs the control plane and etcd components in a highly available mode If your inventory file is located somewhere other than the default of /etc/ansible/hosts, specify the location with the -i option:

configuration options for you • Have worked on request & operational tasks like creating project level role and Role binding, project creation, configuring secrets Select “Create instance” For
