Red Hat Summit4.2. Setting up Google Compute Engine
To set up Google Compute engine, perform the following steps:
4.2.1. SSH Keys
Copy linkLink copied to clipboard!
SSH keys must be generated and registered with the Google Compute Engine project to connect via standard SSH. You can SSH directly to the instance public IP addresses after it is generated.
- Generate an SSH key pair for use with Google Compute Engine using the following command:
ssh-keygen -t rsa -f ~/.ssh/google_compute_engine
# ssh-keygen -t rsa -f ~/.ssh/google_compute_engineCopy to Clipboard Copied! Toggle word wrap Toggle overflow - In the Google Developers Console, click Computer > Compute Engine > Metadata > SSH Keys > Edit.
- Enter the output generated from
~/.ssh/google_compute_engine.pubfile, and click Save. - To enable SSH agent to use this identity file for each new local console session, run the following command on the console:
ssh-add ~/.ssh/google_compute_engine
# ssh-add ~/.ssh/google_compute_engineCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Adding the below line to your
~/.ssh/configfile helps you automate this command.IdentityFile ~/.ssh/google_compute_engine

ssh -i ~/.ssh/google_compute_engine <username>@<instance_external_ip>
# ssh -i ~/.ssh/google_compute_engine <username>@<instance_external_ip>Copy to Clipboard Copied! Toggle word wrap Toggle overflow
The gcloud compute config-ssh command from the Google Cloud SDK populates your
~/.ssh/config file with aliases that allows simple SSH connections by instance name.
4.2.2. Setting up Quota

The minimum persistent disk quotas listed below are required for this deployment. It may be necessary to request a quota increase from Google.
- Local region (see US-CENTRAL1 illustration in Section 4.1.3, “Primary Storage Pool Configuration”)
- Total persistent disk reserved (GB) >= 206,000
- CPUs >= 100
- Remote region (see EUROPE-WEST1 illustration in Section 4.1.4, “Secondary Storage Pool Configuration”)
- Total persistent disk reserved (GB) >= 103,000
- CPUs >=40
