eui/puppeteer

Base Docker environment image for Puppeteer (Headless Chromium Node API) Built containers can be published to the Elastic Docker Registry for use locally or in CI environments.

Getting started

test-docker script

The test-docker script is the primary user of this container. Specifically, the `a11y-testing script therein uses the headless Chromium environment to run EUI's automated axe accessibility testing suite.

Generic node application

Run the container by passing node -e "<yourscript.js content as a string>" as the command:

docker run -i --rm --cap-add=SYS_ADMIN \
    --name puppeteer-chrome eui/puppeteer \
    node -e "`cat yourscript.js`"

Using with the Elastic Container Library

To start, you'll need to setup a local Docker environment. See Docker's "Get started" guide for instructions.

View the current image state in the registry.

View general information on Accessing the Docker registry

Build a new image

From this directory:

docker build [--no-cache] [--tag your_tag] .
  • Use the --no-cache option if attempting the upgrade environment installations, like node.js, for instance.
  • Use the --tag option to give the image a reference name. Helpful if you plan on running the image locally (see next step).

Test a new image locally

To run the test-docker script with the new image locally, you'll need to replace the image name line in the docker run ... command (docker.elastic.co/eui/puppeteer:latest) with the new image ID or tag name (if set during the build with --tag).

Publish a built image

Authentication and membership of the eui-design team on GitHub is required:

  • You can login at https://docker-auth.elastic.co using GitHub OAuth to sign in.
  • This will give you a login command that you can run locally to connect to the registry, like:
docker login -u thompsongl -p supersecret docker.elastic.co

Then tag the built image as latest, first grabbing the image ID using docker images:

docker tag IMAGE_ID docker.elastic.co/eui/puppeteer:latest
docker push docker.elastic.co/eui/puppeteer

Use a published image

Note that authentication is not required.

docker pull docker.elastic.co/eui/puppeteer:latest

docker run [...]

See the test-docker script as an example.
