[BUG] failing to launch browsers in docker container.

[owenpearson]

Context:

• Playwright Version: 0.11.1
• Operating System: node:alpine3.11 container on docker for windows
• Extra: running as part of gitlab ci pipeline

Describe the bug

running playwright tests in a gitlab ci pipeline is causing an error for me. the gitlab ci runner runs commands inside a node:alpine docker container. i get the following output during npm install:

> node install.js

chromium downloaded to /builds/app/node_modules/playwright-core/.local-chromium/linux-740847

firefox downloaded to /builds/app/node_modules/playwright-core/.local-firefox/linux-1029

webkit downloaded to /builds/app/node_modules/playwright-core/.local-webkit/linux-1151

but then when i get to running the tests i get an exception and the output like:

    Failed to launch browser: Error: spawn /builds/app/node_modules/playwright-core/.local-firefox/linux-1029/firefox/firefox ENOENT

      at ChildProcess.<anonymous> (node_modules/playwright-core/lib/server/processLauncher.js:43:20)

(similar for webkit and chromium)

Thanks for reporting this, @owenpearson. To debug issues like this, it helps to add dumpio: true to the browser launch arguments, and see the underlying issue.

Typically this issue implies that the docker image is missing some system dependencies. I have a working version which uses Ubuntu 18.04 as a base image, that you might be able to refer to. Do you think you can use that instead? If not, I'll take this issue as a suggestion to add a recommended dockerfile setup for Alpine.

ah yeah, that will be it. i'm away from my workstation for today so i'll give it a try tomorrow. fortunately gitlab runner has support for bionic so hopefully i won't need a reccomended setup for alpine. thanks a lot 👍

I'm getting the same error when try to run inside a docker

# 6. (Optional) Install XVFB if there's a need to run browsers in headful mode

How can I solve this?

My open browser method

  const browser = await webdriver.launch({
    headless: false,
    dumpio: true,
    args: ['--no-sandbox', '--disable-setuid-sandbox', '--disable-dev-shm-usage']
  });
