I am trying to run TestCafe tests inside docker container.

I am able to run my tests with npm run testrunner locally. Inside Docker container, I get different errors on different tries.

The errors I get are as follows:

With firefox:headless --no-sandbox --disable-dev-shm-usage option:

...-tests  | Error: Cannot establish one or more browser connections.
...-tests  | 3 of 3 browser connections have not been established:
...-tests  | - firefox:headless --no-sandbox --disable-dev-shm-usage
...-tests  | - firefox:headless --no-sandbox --disable-dev-shm-usage
...-tests  | - firefox:headless --no-sandbox --disable-dev-shm-usage
...-tests  | 
...-tests  | Hints:
...-tests  | - Increase the Browser Initialization Timeout if its value is too low (currently: 2 minutes for local browsers and 6 minutes for remote browsers). The timeout determines how long TestCafe waits for browsers to be ready.
...-tests  | - The error can also be caused by network issues or remote device failure. Make sure that your network connection is stable and you can reach the remote device.

With chromium:headless --no-sandbox --disable-dev-shm-usage option:

...-tests  | Error: Unable to open the "chromium:headless --no-sandbox --disable-dev-shm-usage" browser due to the following error:

With chromium:headless --no-sandbox --disable-dev-shm-usage option and const testcafe = await createTestCafe({ experimentalProxyless: true }); initialization:

runner.js

const createTestCafe = require('testcafe');

(async function () {
  const testcafe = await createTestCafe({ experimentalProxyless: true });
  try {
    const runner = testcafe.createRunner();
    const failed = await runner
      .src(['src/tests/masterdata'])
      .browsers('chromium:headless --no-sandbox --disable-dev-shm-usage')
      .concurrency(3)
      .run();

    console.log('Tests failed: ' + failed);
  } finally {
    await testcafe.close();
  }
})();

What do I need to run tests in Docker?
