Hi,

If I add this image - image: selenium/standalone-chrome

I get error on boot:

I am not sure what am I doing wrong. As far as I can tell from the documentation, this image should do all the magic I need for selenium to run and it will also expose it on the right port on “localhost” just like I needed.

  build:
    docker:
      # specify the version you desire here
