What should I check about my SSH keys before I run Terraform?
Verify that a key pair exists in ~/.ssh. If no key pair exists, generate a new pair and keep the private key secure. You’ll use the private key to connect to the VMs created by Terraform.
How do I know I’m authenticated to GCP for Terraform?
Use the Google Cloud CLI to confirm an active account and project, then obtain user credentials. Terraform can communicate with GCP using those credentials.
What result should I expect after applying the Terraform configuration?
You should see new Arm-based instances and a Jump Server in the GCP console. You can SSH to the Jump Server with your private key and connect from there to the target instances.
How do I confirm the VMs are Arm-based on Google Cloud?
Open the instance details in the GCP console and check that the machine type indicates an Arm-based option, such as Google Axion.
How do I connect to the private instance through the Jump Server?
Run ssh -J username@jump-host-IP username@target-server-IP. Replace jump-host-IP with the bastion’s external IP and target-server-IP with the private instance’s internal IP. Use your IAM email address in the SSH username format (abc@1234.com -> abc_1234_com).
