devops: add utility to count compressed docker image size (#2920)
This adds a new script to calculate docker image size with
all parent layers.

Note: take this metrics with a grain of salt, since in reality
docker compresses and reuses layers.

Some historic stats obtained with this script:

Running Playwright in Docker

Dockerfile.bionic is a playwright-ready image of playwright. This image includes all the dependencies needed to run browsers in a Docker container.

Usage

docker hub

This image is published on Docker Hub.

Pull the image

$ docker pull mcr.microsoft.com/playwright:bionic

Run the image

$ docker container run -it --rm --ipc=host --security-opt seccomp=chrome.json mcr.microsoft.com/playwright:bionic /bin/bash

Note that:

  • The seccomp profile is required to run Chrome without sandbox. Thanks to Jessie Frazelle.
  • Using --ipc=host is also recommended when using Chrome (Docker docs). Chrome can run out of memory without this flag.

Using on CI

See our Continuous Integration guides for sample configs.
