Cypress and Docker

We have a Docker image available that is build on top of the Cypress Docker image and will run your Cypress tests locally and in CI pipelines.

Using docker means folks don't have to install all the node stuff - Sam Lerner

GUI

The Docker image above supports running the GUI (aka interactive mode) using X11. From https://github.com/drydockcloud/ci-cypress/blob/master/docker-compose.cypress.yaml:

version: '3'

services:
  # Example docker-compose service for cypress:
  cypress:
    image: drydockcloud/ci-cypress:latest
    command: autotest
    volumes:
      - ./tests/cypress:/src
      - ./results/cypress:/results
    # Optional - uncomment following 3 lines to provide X11 access for interative use:
    #  - /tmp/.X11-unix:/tmp/.X11-unix
    #environment:
    #  - DISPLAY
    # To use the above, run the following before starting docker-compose:
    #  OS X:
    #   IP=$(ipconfig getifaddr en0)
    #   /usr/X11/bin/xhost + $IP
    #   DISPLAY=$IP:0
    #  GNU/Linux:
    #   xhost +local:
    depends_on:
      - web
