de-graphql

Work towards exposing the Discovery Environment data model through GraphQL using Apollo Server.

Prerequisites

You'll want the following installed to work on this:

• node/npm to install dependencies and run the service.
• kubectl to forward ports to services running in the DE's clusters.
• docker if you're going to build images locally.

Configuration

de-graphql uses the following environment variables for configuration:

• APPS_URL - The base URL to the DE's apps service.
• GATEWAY - The base URL to the OpenFaaS gateway serving up the de-functions functions.
• PERMISSIONS_URL - The base URL to the DE's permissions service.
• USER_INFO_URL - The base URL to the DE's user-info service.
• METADATA_DB_URL - The connection string for the DE's metadata database.
• DE_DB_URL - The connection string for the DE's de-db database.

The METADATA_DB_URL should look like postgres://<user>:<password>@<hostname>:<port>/metadata/sslmode=disable.

The DE_DB_URL should look like postgres://<user>:<password>@<hostname>:<port>/de?sslmode=disable.

Start up

To start it locally, run npm install and then node src/index.js with the above environment variables set in the top-level of the repository.

Building

Run docker build --rm -t <image> . in the top-level directory of the respository. Push the image like any other Docker image.
