This repository contains the implementation for the GCP provider for SnapMaster. It is invoked from the main SnapMaster-API service when the snap invokes GCP actions.
Provider-GCP utilizes the express web server, and relies on Auth0 for authenticating calls (which can only be made with authorization tokens obtained from the Auth0 token endpoint).
It is a Google Cloud Platform app, with dependencies on Google Cloud Build, Google Cloud Run, and Google Cloud Pubsub.
Runs the backend with ENV=dev, which invokes the dev environment. This will append "-dev" to the pubsub topic (invoke-load-dev), scheduler job, etc.
The pub-sub subscription will run in pull mode, and is invoked by the scheduler every hour on the hour.
The express webserver will default to listening on port 8081. Override with PORT=xxxx variable.
Runs the backend with ENV=prod, which invokes the production environment. This will append "-prod" to various resources such as the pubsub topic (invoke-load-prod), scheduler job, etc.
The pub-sub subscription will run in push mode, calling the /invoke-load API, and is invoked by the scheduler every hour on the hour.
The express webserver will default to listening on port 8080. Override with PORT=xxxx variable.
Runs the backend with dev account credentials but with the prod configuration, which runs
a production-like hosted environment in the dev account.
These will build the Docker container for the provider using Google Cloud Build, and deploy it to Google Cloud Run.
This combines the build and deploy operations to automate the deployment of the current source code with one command into the respective environment.
The app is bootstrapped out of index.js, which pulls in all other source dependencies out of the src directory.
Contains all the config for the project. These files aren't committed to source control since they contain secrets.
The provider expects an auth0_config_{dev|prod}.json file for application keys and secret keys for your Auth0 tenant.

"domain": "YOURDOMAIN.auth0.com",
"client_id": "THE CLIENT ID FOR YOUR DOMAIN",
"client_secret": "THE CLIENT SECRET FOR YOUR DOMAIN",
"audience": "https://api.snapmaster.io"
}
Contains scripts to build and deploy the provider to GCP.
Contains scaffolding source files (environment.js, requesthandler.js) that can be reused across provider implementations.
Contains the provider-specific code - this can be a rough template for other providers. The GCP provider utilizes the src/actions/actions.js module to implement the action processing.
Contains the actions.js wrapper and a set of bash scripts (e.g. deploy.sh) corresponding to provider operations.
