rke2-terraform

A repository that creates a RKE2 kubernetes cluster using Terraform

SSH access to nodes

In the file terraform.tfvars you can set the password. The default is "softica".

To create a new password, run the following command and give it the password when prompted:

mkpasswd --method=SHA-512 --rounds=4096

or

echo "your-password" | mkpasswd --method=SHA-512 --rounds=4096 -

The password is needed by terraform, so we keep a version of it in plain text as well. So remember to change the variable kubernetes_node_ssh_password_plain as well.

Getting your kube config

SSH into the first master node and run the following command

cat /etc/rancher/rke2/rke2.yaml

or get it to a local file like this with the ssh username and ssh password you have chosen.

The command will overwrite your current config file !

ssh kubernetes@10.18.3.10 cat /etc/rancher/rke2/rke2.yaml > ~/.kube/config

In the config file, it refers to the conrolplane at 127.0.0.1 which doesnt work for us. So edit the file and change 127.0.0.1 with the ip of the control plane node (default 10.18.3.10)
