[Bug] - Firefox with Jenkins inside Docker does not work

Context: Project: https://github.com/APAODUQS/playwright-demo Playwright image: mcr.microsoft.com/playwright:v1.20.1-focal Jenkins Server version: 2.277.4

#Jenkinsfile
pipeline {
   agent { docker { image 'mcr.microsoft.com/playwright:v1.20.1-focal' } }
   stages {
      stage('e2e-tests') {
         steps {
            sh 'npm install'
            sh 'npm run test -- --project Chrome --grep @playwright'
         }
      }
   }
}

Describe the problem: I am trying to run the tests from a jenkins build as the documentation indicates: https://playwright.dev/docs/ci#jenkins, but when I try to run it with the previous configuration, with the playwright docker image I get this error:

Then, when I run:

        sh '''
            npm install
            npx playwright install chrome
            npm run test -- --project Chrome --grep @playwright
        '''

I get the error:

Then I tried to run it with tue command npx playwright install:

        sh '''
            npm install
            npx playwright install
            npm run test -- --project Chrome --grep @playwright
        '''

And I get the same first error.

I have tried a lot of things but they still are not working. Could you help me or suggest me how I could run it?

Thanks @APAODUQS! Is that output from a run in a container? If not (and theirs a display), remove the xvfb-run bit—that’s only needed if there isn’t a display available already. That looks like a different error from https://github.com/microsoft/playwright/issues/13230#issuecomment-1086195132.

Since there are now several confirmations that it works for some Jenkins Docker configurations and the surface area for configuring Jenkins and its agents is large, folks in the Jenkins community will likely be better able to help you troubleshoot.

Thanks for your patience, and feel free to post back what you find!
