How can I install chromedriver within bitbucket-pipelines.yml - Ruby image

[Peter Hughes]

I am currently trying to set up a pipeline to build and test a Ruby on Rails project. Which contains specs/tests in rspec/capybara, which are run using headless chrome.

In order for this to work, I need to install chromedriver on the docker image, but the preferred way to do this is by using a package manager.

However, I am struggling to install the necessary dependencies, i.e npm, or homebrew.

I have tried to install Node, with no luck, and similarly with LinuxBrew - i.e on installing brew within the script section

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install)"

I get the following error:

Don't run this as root!

Can anyone give any advice as the best way to install other packages on a Ruby image?

Many Thanks

Hi Peter,

You can configure your pipeline to run as a user that isn't root. For example:

image:
  name: image-name:tag
  run-as-user: 1000 # root is always 0. So this will make you non-root.
pipeline:
  default:
    - step:
        script:
          - ./do-the-thing

I noticed there seemed to be no reference to this in the documentation, so I've opened an internal ticket to fix that.

Thanks,

Phil
