Docker grid node xvfb resolution.

[Остап Олексин]

Hi, I'm new to docker and I was wondering, is it possible to start a firefox or chrome node container with a custom xvfb resolution?

Already found the solution myself. You can define the xvfb display resolution by passing SCREEN_WIDTH and SCREEN_HEIGHT variables to the container:

docker run -d -e SCREEN_WIDTH=1920 -e SCREEN_HEIGHT=1080 --link selenium-hub:hub selenium/node-firefox 

or just add them to the yml file if you are using docker compose:

firefox:
  image: selenium/node-firefox

  environment:

    SCREEN_WIDTH: 1920
    SCREEN_HEIGHT: 1080

for me it doesn't work.. It still see:
System.out.println(driver.manage().window().getSize().getWidth()); // = 1440
System.out.println(driver.manage().window().getSize().getHeight()); // = 810

My docker-compose.yml file look like this:
----------------------------------------
seleniumhub:
  image: selenium/hub
  ports:
    - 4444:4444

firefoxnode:

  image: selenium/node-firefox
  environment:
    SCREEN_WIDTH: 1920
    SCREEN_HEIGHT: 1080

  ports:
    - 5900
  links:
    - seleniumhub:hub
chromenode:
  image: selenium/node-chrome

  environment:
    SCREEN_WIDTH: 1920
    SCREEN_HEIGHT: 1080

  ports:
    - 5900
  links:
    - seleniumhub:hub
---------------------------------------------

Do you have any clue what I need to change?

You have to use a debug container.

If not using debug container, maximize won't work, but you can set size manually.
