jacalloc

Lightweight python app for allocating resources

Running in docker

Standard

docker-compose -f docker-compose.yml up

Custom gcloud backend

• For each gcloud project my-project,
  • create a file my-project.json with a service account with Project:Editor permissions
  • create a file my-project.env of the format:

  PROJECT=my-project
  ZONE=us-central1-a
  SVC_ACCT_PATH=/app/my-project.json

• Add these files as volumes to the app container in docker-compose-gce.yml:

  volumes:
    - ./my-project.json:/app/my-project.json:ro
    - ./my-project.env:/app/my-project.env:ro

• Run the compose:

  docker-compose -f docker-compose-gce.yml up
  

HTTP API

Interactive API documentation is run through Flasgger.

http://localhost:5000/apidocs/index.html

OAuth

If running with a gcloud backend you will need to set up Oauth to validate endpoints. Create an oauth credential in your google project. You'll then need to edit app/templates/flasgger/index.html:

window.swaggerUi = new SwaggerUi({
       url: url,
       validatorUrl: null,
       dom_id: "swagger-ui-container",
       oauth2RedirectUrl: 'http://your-host-path/flasgger_static/o2c.html', // if running locally, use 'http://localhost:5000/flasgger_static/o2c.html'
       supportedSubmitMethods: ['get', 'post', 'put', 'delete', 'patch'],
       onComplete: function(swaggerApi, swaggerUi){
           if(typeof initOAuth == "function") {
               initOAuth({
                   clientId: "your-client-id-if-required",
                   clientSecret: "your-client-secret-if-required",
                   realm: "your-project-name",
                   appName: "your-app-name",
                   scopeSeparator: " ",
                   additionalQueryStringParams: {}
               });
           }

Enter a redirect URI (which will need to be added to the authorized redirect URIs on your credential), the client ID of your credential as clientId, and the google project it exists in as realm.
