Short Description
A frontend for browsing the DC/OS Universe packages
Full Description

dcos-universe-browser

The repository provides a web application for browsing the DC/OS Universe packages.

Using

You can find the deployed application at https://universe.serv.sh, install it locally, or use the tobilg/dcos-universe-browser Docker image.

Installation

Prerequisites

  • Node.js >= 4
  • Git

Local installation

You can host a local instance via

git clone https://github.com/tobilg/dcos-universe-browser.git

and installing the dependencies with

npm run install-deps

and starting the application with

npm start

Docker image

You can run the application via a Docker image like this:

docker run -d --name dcos-universe-browser -p 3000:3000 tobilg/dcos-universe-browser

This will expose the application on port 3000 on the Docker host.

Configuration

You can use the following environment variables to influence the application's behavior:

  • HOST: The IP address to which the application should bind to. Default is 127.0.0.1.
  • PORT0: The port on which the application is binding to. Default is 3000.
  • NODE_ENV: The environment settings for Node.js. Default is development, the Docker image uses production as default.
  • REFRESH_UNIVERSE: The number of milliseconds to wait before a refresh of the Universe package info. The application caches the package info locally, and refreshes it in intervals as defined. Default is 3600000 (one hour).
  • REFRESH_EXAMPLES: The number of milliseconds to wait before a refresh of dcos/examples data. The application does a git clone on start, and refreshes it (via git pull) in intervals as defined. Default is 3600000 (one hour).

Application details

How is it built?

  • The backend is a Node.js application, using Express.js to serve static files, and a REST API which is a wrapper around the Universe data.
  • The frontend is an Angular 1 app, using Bootstrap 3 and various third-party modules.

What does this application do?

  • It fetches the DC/OS Universe information from https://universe.mesosphere.com/repo, optimizes the data structures for UI usage, and caches it until the next request interval.
  • It clones the dcos/examples project, containing the DC/OS package examples, and merges them with the Universe information. The markdown is rendered as HTML dynamically.
  • It renders the combined data as a web application (see above).

Roadmap

  • Improvements for mobile.
  • Create package options.json files via UI for usage with the DC/OS CLI.
  • Add dynamic meta tags & sharing support, via jvandemo/angular-update-meta.
  • Integrate prerender.io to optimize for search engines.
