* Challenge:
* Ensuring secure access to Google Cloud resources from GitHub Actions CI/CD pipelines without directly managing service account keys.
* Workload Identity Federation:
* Allows for the delegation of access to Google Cloud resources based on federated identities, such as those from GitHub.
* Benefits:
* This approach eliminates the need to manage service account keys, reducing the risk of key leakage.
* It leverages GitHub's identity provider capabilities to authenticate and authorize access.
* Steps to Configure Workload Identity Federation:
* Step 1: Create a workload identity pool in Google Cloud.
* Step 2: Add GitHub as an identity provider within the pool.
* Step 3: Configure the necessary permissions and bindings for the identity pool to allow GitHub Actions to access Google Cloud resources.
* Step 4: Update the GitHub Actions workflow to use the identity federation for authentication.
