| <div class="block">Provides a basic uploader class for uploading topology packages to Google Cloud Storage (gcs). |
| <p> |
| This uploader will write topology packages to |
| https://storage.googleapis.com/bucket-name/topology-name/topology.tar.gz |
| This provides a known package destination location which can be used to download |
| the topology package in order to run the topology. |
| |
| Clients must have write access to the bucket in order to upload topologies. Authentication |
| can be provided in two ways: |
| 1 - A file path to the service account credentials file (https://cloud.google.com/storage/docs/authentication#service_accounts) |
| example: heron.uploader.gcs.credentials_path: /Users/username/my-service-account-credentials.json |
| 2 - through the gcloud client (https://cloud.google.com/storage/docs/authentication#libauth) |
| example: gcloud auth application-default login |
| Option 2 is used when a heron.uploader.gcs.credentials_path: is not provided. |
| |
| <p> |
| This class also handles the undo action by copying any existing topology.tar.gz package found |
| in the folder to previous-topology.tar.gz. In the event that the deploy fails and |
| the undo action is triggered the previous-topology.tar.gz file will be renamed |
| to topology.tar.gz effectively rolling back the live code. In the event that the deploy is |
| successful the previous-topology.tar.gz package will be deleted as it is no longer needed. |
| <p> |
| The config values for this uploader are: |
| heron.class.uploader (required) org.apache.heron.uploader.gcs.GcsUploader |
| heron.uploader.gcs.bucket (required) The bucket that you have write access to where you want the topology packages to be stored |
| heron.uploader.gcs.credentials_path (optional) Google Services Account Credentials to use</div> |
