i would like to have 3 node RKE cluster. I am using a deployment machine on which i am running the RKE version v1.0.8 and would to create cluster with other 3 nodes.
all nodes are having docker and version centos 7.x including deployment node.
i have rke as sudl ssh user in all the 3 nodes not in the deployment node.
when i try to run the rke up --config cluster.yml i get the below error:
Failed to set up SSH tunneling for host [xx.xx.xx.xx]: Can’t retrieve Docker Info: error during connect: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.24/info: Unable to access node with address [xx.xx.xx.xx:22] using SSH. Please check if the configured key or specified key file is a valid SSH Private Key. Error: Error configuring SSH: ssh: no key found.
my cluster.yml is as follows:
please consult the documentation on how to configure custom RKE images.
