Azure to GCP

azure-to-gcp-integration

Demo

Setup

Ensure you are logged into both GCP & Azure systems from your CLI before executing below terraform commands.

Verify GCP

gcloud auth login
gcloud auth application-default login

List projects and choose one.

gcloud projects list
gcloud config set project <PROJECT_NAME>

gcloud config list

Verify Azure

az account show

Integration

Connect to GCP systems from Azure Cloud. In this example, we will use Azure VM to connect with GCP resources.

export GCP_PROJECT_NAME=$(gcloud config list --format="value(core.project)")
terraform init
terraform plan -var gcp_project_name=$GCP_PROJECT_NAME
terraform apply -var gcp_project_name=$GCP_PROJECT_NAME

Post terraform apply, copy the ssh command from the output and login to the Azure VM.

  1. Some pre-requisities will be installed
  2. Connectivity to the GCP systems will be established
  3. Test it by running, gcloud iam service-accounts get-iam-policy $(gcloud auth list --format="value(account)")

Destroy resources

terraform destroy -var gcp_project_name=<GCP_PROJECT_NAME>

NOTE

There's no in-built terraform module to create credential config, gcloud iam workload-identity-pools create-cred-config. This command will be executed on the local machine using terraform's null_resource capability.
