Google Cloud project setup

This page outlines the steps that the ForgeOps Team took when setting up a Google Cloud project before deploying the CDM.

Perform these steps before you deploy the CDM:

Log in to the Google Cloud Console and create a new project.
Authenticate to the Google Cloud SDK to obtain the permissions you’ll need to create a cluster:
1. Configure the gcloud CLI to use your Google account. Run the following command:
  $ gcloud auth application-default login
2. A browser window appears, prompting you to select a Google account. Select the account you want to use for cluster creation.
  
  A second screen requests several permissions. Select Allow.
  
  A third screen should appear with the heading, You are now authenticated with the gcloud CLI!
Assign the following roles to users who will be creating Kubernetes clusters and deploying the CDM:
- Editor
- Kubernetes Engine Admin
- Kubernetes Engine Cluster Admin
- Project IAM Admin
Remember, the CDM is a reference implementation, and is not for production use. The roles you assign in this step are suitable for the CDM. When you create a project plan, you’ll need to determine which Google Cloud roles are required.
Copy the file that contains default Terraform variables to a new file:
1. Change to the /path/to/forgeops-extras/terraform directory.
2. Copy the terraform.tfvars file to override.auto.tfvars ^[1].
Copying the terraform.tfvars file to a new file preserves the original content in the file.
Determine the cluster size: small, medium, or large.
Define your cluster’s configuration:
1. Open the override.auto.tfvars file.
2. Determine the location of your cluster’s configuration in the override.auto.tfvars file:
  
  Cluster size Section containing the cluster configuration
  
  Small
  
  cluster.tf_cluster_gke_small
  
  Medium
  
  cluster.tf_cluster_gke_medium
  
  Large
  
  cluster.tf_cluster_gke_large
3. Modify your cluster’s configuration by setting values in the section listed in the table:
  1. Set the value of the enabled variable to true.
  2. Set the value of the auth.project_id variable to your new Google Cloud project. Specify the project ID, not the project name.
  3. Set the value of the meta.cluster_name variable to the name of the GKE cluster you’ll create.
  4. Set the values of the location.region and location.zones variables to the region and zones where you’ll deploy the CDM.
    
    Before continuing, go to Google’s Regions and Zones page and verify that the zones you have specified are available in your region you specified.
4. Save and close the override.auto.tfvars file.
Ensure your region has an adequate CPU quota for the CDM.

Locate these two variables in your cluster’s configuration in the override.auto.tfvars file:
- node_pool.type: the machine type to be used in your cluster
- node_pool.max_count: the maximum number of machines to be used in your cluster
Your quotas must be large enough to let you allocate the maximum number of machines in your region. If your quotas are too low, request and wait for a quota increase from Google Cloud before attempting to create your CDM cluster.

Cluster size	Section containing the cluster configuration
Small	`cluster.tf_cluster_gke_small`
Medium	`cluster.tf_cluster_gke_medium`
Large	`cluster.tf_cluster_gke_large`

Next step

1. The Terraform configuration contains a set of variables under forgerock that adds labels required for clusters created by ForgeRock employees. If you’re a ForgeRock employee creating a cluster, set values for these variables.
