dev-scripts proxy automation.
# I use ~/.ssh/config to create ssh aliases for my machines.
# script requires passwordless ssh access
# script requires tmux
# After sourcing the script, just call rhhi_cluster_env_init, this will create a proxy to the host on 8053 in a tmux session and copy the kubeconfig from the host
# Once inited, other terminals can be brought into the env using rhhi_cluster_env which sets the env vars `https_proxy` and KUBECONFIG

Machine Config Operator docs on applying configuration

  • Find the machine MachineConfigurationPools that refer to the worker/master pools: oc get mcp --show-labels

  • Create a MachineConfig object with machineconfiguration.openshift.io/role = <MachineConfigPool Name>

  • The MCO will render a new rendered-worker-... MachineConfig and apply a rolling update of the configuration.
