ngcontainer

This docker container provides everything needed to build and test Angular applications:

• node 10.9.0
• npm 6.2.0
• yarn 1.9.2
• Java 8 (for Closure Compiler and Bazel)
• Bazel build tool v0.17.1 - http://bazel.build
• Google Chrome 69.0.3497.81
• Mozilla Firefox 47.0.1
• xvfb (virtual framebuffer) for headless testing
• Brotli compression utility, making smaller files than gzip

By using this, you avoid installation steps in your CI scripts and get a more consistent dev environment.

Example

See https://github.com/angular/closure-demo/blob/master/.circleci/config.yml where this container is used in CircleCI.

To run locally:

$ docker run -it --rm angular/ngcontainer

Running tests

Any program that needs to talk to a browser (eg. protractor) should be run under xvfb when executing on a headless machine like on CI. The nice way to factor this is to have your top-level test command which you run locally:

$ yarn test

Then in your CI configuration, you'd run

$ xvfb-run -a yarn test

For Developers
