Rancher Cloud-config.yml example cloud-init add SSH keys
If you use Rancher to deploy your Kubernetes nodes in VMware vSphere or any other cloud environment, you can make use of the Cloud Config configuration in the Node template to specify various initialization configuration settings. One of the basic things you can do is specify SSH keys in your Node Template for Rancher. This allows connecting to your Kubernetes nodes locally if these become disconnected from Rancher. In the video tutorial we look at how to implement the cloud config for SSH keys in VMware vSphere Kubernetes nodes or any other cloud environment.
