Travis CI ember web client

Build Status

Running the app

The app is developed using Ember CLI. It requires nodejs with npm installed.

In order to run the app you need to install dependencies with:

npm ci

And then install ember-cli globally in order to have access to the ember command:

npm install -g ember-cli

Now you can run the server:

ember serve

And open http://localhost:4200 in the browser.

Alternatively you can run ember build --watch and start the server with waiter/script/server

Waiter Workarounds

Should you encounter issues installing Puma while bundling Waiter on a recent OSX version, you need to tinker with Homebrew:

brew install openssl
brew link --force openssl

You should then be able to run bundle install as usual.

Running the app in private repos mode

At the moment Travis CI is available as two separate sites - https://travis-ci.org for Open Source projects and https://travis-ci.com for private projects. travis-web will connect to the Open Source version by default. In order to connect it to the API for private projects you need to setup your .env file.

Copy .env.example to .env

$ cp .env.example .env

Update the .env file to run the app in private repos mode:

TRAVIS_PRO=true

After setting up environment variables, you can run the app like so:

ember serve --ssl --ssl-key=ssl/server.key --ssl-cert=ssl/server.crt

One caveat here is that the command will start server with SSL, so the page will be accessible at https://localhost:4200 (note https part).

Running on SSL in general

Sometimes there is a need to test the app with an SSL connection. This is required to make Pusher work when running Travis CI Pro, but it may also be needed in other situations.

There's already an SSL certificate in the ssl directory, which is set for localhost host. If you want to use it, you can start the server with:

ember serve --ssl --ssl-key=ssl/server.key --ssl-cert=ssl/server.crt

In case you want your own certificate, you can follow the instructions posted here: https://gist.github.com/trcarden/3295935 and then point the server to your certificate with --ssl-key and --ssl-cert.

Running tests

To run the test suite execute:

ember test

You can also start an interactive test runner for easier development:

ember test --serve

Linting

Feature Flags

travis-web is beginning the transition to use feature flags wherever it makes sense. To enable/disable/add/remove a feature flag for the application, you can edit the config/environment.js file. For instance, to enable some-feature, you would simply add/update the file like so:

  {
    featureFlags: {
      'some-feature': true
    }
  }

This uses the awesome ember-feature-flags addon under the hood, so be sure to read its own documentation for more information.

Debugging

Ember's default logging has been disabled in all environments by default and moved to a feature flag. To enable it, simply edit the debug-logging feature flag as mentioned previously in the Feature Flags section.

Deploying

ember-cli-deploy is available for deploying pull requests. See after_success in .travis.yaml and associated scripts for details. It uses the “lightning strategy” of deploying assets to S3 and index.html to a Redis server. You can deploy from your own machine too. First, update your .env file with the following variables:

AWS_KEY=key
AWS_SECRET=secret

Then run:

npm run deploy

After success, your deployment will be available at branch.test-deployments.travis-ci.org.

See the documentation for the full list of deployment environments and more details.

The Redis server is a modified version of waiter/lib/travis/web/app.rb. We will eventually replace that with travis-web-index and move to using ember-cli-deploy for all deployments.

Ember beta and canary deployments

Upon a merge to master, the application is built with the latest beta and canary versions of Ember, running against the production API. This uses the same infrastructure as the pull request deployments. You can visit these deployments at:

These deployments are also performed with the weekly cron build.

Ask Travis updates

Note that scripts/k8s-deploy.sh script is started on each deployment. If there's an AIDA_URL env defined - aida.js will be downloaded from this URL and replace the original delivered in asktravis package.
