Deploy Router to Cloud Foundry

This repo demonstrates a minimal Router configuration and Cloud Foundry manifest file to deploy the Router to Cloud Foundry.

Important Notes and Caveats

• The code in this repo is for demonstration purposes only. Do not run in production without first hardening it.
• create_local_schema.sh, supergraph.yaml, and schema.graphql are for demonstration purposes. In a real environment, you'd pull the schema from GraphOS using your Apollo Key and Graph Ref.
• start_router.sh runs the Router in dev mode for testing purposes. Do not run with dev flag in production!

Code Highlights

• In router/manifest.yaml, we use the binary_buildpack build pack. We configure it to use Router's health check endpoint instead of the default port health check.
• In router/router-config.yaml, we specify the supergraph and health_check listen properties with 0.0.0.0:${env.PORT}. 0.0.0.0 is the IP that CF uses and ${env.PORT} injects in the PORT environment variable provided by CF.

Deploying Example to PCF

1. Deploy the subgraph by running cf push from the subgraph directory. Make note of the URL of the subgraph.
2. Update router/supergraph.yaml with the URL of your subgraph
3. Run router/create_local_schema.sh to generate the supergraph schema
4. Deploy the Router by running cf push from the router directory. You should be able to open the URL provided by CF in your browser and query the Router.

Note: Steps 2 and 3 are for demo purposes only. In a real environment, the Router would pull the schema from GraphOS using your Apollo Key and Graph Ref. These would be injected secret environment variables in CF for your APOLLO_KEY and APOLLO_GRAPH_REF.
