Accessing a Windows node using SSH

You can access a Windows node by using a secure shell (SSH).

Prerequisites

• You have installed the Windows Machine Config Operator (WMCO) using Operator Lifecycle Manager (OLM).

• You have created a Windows compute machine set.

• You have added the key used in the cloud-private-key secret and the key used when creating the cluster to the ssh-agent. For security reasons, remember to remove the keys from the ssh-agent after use.

• You have connected to the Windows node using an ssh-bastion pod.

Procedure

• Access the Windows node by running the following command:

  $ ssh -t -o StrictHostKeyChecking=no -o ProxyCommand='ssh -A -o StrictHostKeyChecking=no \
      -o ServerAliveInterval=30 -W %h:%p core@$(oc get service --all-namespaces -l run=ssh-bastion \
      -o go-template="{{ with (index (index .items 0).status.loadBalancer.ingress 0) }}{{ or .hostname .ip }}{{end}}")' <username>@<windows_node_internal_ip> (1) (2)

  1. Specify the cloud provider username, such as Administrator for Amazon Web Services (AWS) or capi for Microsoft Azure.

  2. Specify the internal IP address of the node, which can be discovered by running the following command:

     $ oc get nodes <node_name> -o jsonpath={.status.addresses[?\(@.type==\"InternalIP\"\)].address}
