Plan: 1 to add, 0 to change, 0 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
google_compute_instance.cluster: Creating …
google_compute_instance.cluster: Still creating … [10s elapsed]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
Add a public static IP address and SSH key to the node:
essh @ kubernetes-master: ~ / node-cluster $ ssh-keygen -f node-cluster
Generating public / private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in node-cluster.
Your public key has been saved in node-cluster.pub.
The key fingerprint is:

Let's check the SSH connection to the server:
essh @ kubernetes-master: ~ / node-cluster $ ssh -i ./node-cluster essh@35.228.82.222
The authenticity of host '35 .228.82.222 (35.228.82.222) 'can't be established.
ECDSA key fingerprint is SHA256: o7ykujZp46IF + eu7SaIwXOlRRApiTY1YtXQzsGwO18A.
