Create an SSH key pair

To enable encrypted communications with your cluster, you must create an asymmetric key pair (a public and a private key) and associate it with your control plane or node pool virtual machines.

To generate an asymmetric key pair, run the following command:

 ssh-keygen  
-t  
rsa  
-m  
PEM  
-b  
 4096 
  
-C  
 " COMMENT 
" 
  
 \ 
  
-f  
 SSH_PRIVATE_KEY 
  
-N  
 "" 
  
 1 
>/dev/null 

Replace the following:

• SSH_PRIVATE_KEY : a file name to save the key in
• COMMENT : a text string describing the key

This creates two files: SSH_PRIVATE_KEY containing your SSH private key, and SSH_PRIVATE_KEY .pub containing the corresponding public key.

To save your SSH public key into an environment variable, run the following command:

 SSH_PUBLIC_KEY=$(cat SSH_PRIVATE_KEY 
.pub)
