| # Google Cloud node deployments and tests that run when Rust code or dependencies are modified, | |
| # but only on PRs from the ZcashFoundation/zebra repository. | |
| # (External PRs are tested/deployed by mergify.) | |
| # | |
| # 1. `versioning`: Extracts the major version from the release semver. Useful for segregating instances based on major versions. | |
| # 2. `build`: Builds a Docker image named `zebrad` with the necessary tags derived from Git. | |
| # 3. `test-configuration-file`: Validates Zebra using the default config with the latest version. | |
| # 4. `test-configuration-file-testnet`: Tests the Docker image for the testnet configuration. | |
| # 5. `test-zebra-conf-path`: Verifies Zebra with a custom Docker config file. | |
| # 6. `deploy-nodes`: Deploys Managed Instance Groups (MiGs) for Mainnet and Testnet. If triggered by main branch pushes, it always replaces the MiG. For releases, MiGs are replaced only if deploying the same major version; otherwise, a new major version is deployed. | |
| # 7. `deploy-instance`: Deploys a single node in a specified GCP zone for testing specific commits. Instances from this job aren't auto-replaced or deleted. | |
| # | |
| # The overall goal is to ensure that Zebra nodes are consistently deployed, tested, and managed on GCP. | |
| name: Deploy Nodes to GCP | |
| # Ensures that only one workflow task will run at a time. Previous deployments, if | |
| # already in process, won't get cancelled. Instead, we let the first to complete | |
| # then queue the latest pending workflow, cancelling any workflows in between. | |
| # | |
| # Since the different event types each use a different Managed Instance Group or instance, | |
| # we can run different event types concurrently. | |
| # | |
| # For pull requests, we only run the tests from this workflow, and don't do any deployments. | |
| # So an in-progress pull request gets cancelled, just like other tests. | |
