 Bitbucket Pipelines can use public [Docker images as build environments](https://confluence.atlassian.com/bitbucket/use-docker-images-as-build-environments-792298897.html). To run Playwright tests on Bitbucket, use our public Docker image ([see Dockerfile](docker/README.md)).

 While the Docker image supports sandboxing for Chromium, it does not work in the Bitbucket Pipelines environment. To launch Chromium on Bitbucket Pipelines, use the `--no-sandbox` launch argument.

+
+This image is published on [Docker Hub](https://hub.docker.com/_/microsoft-playwright).
+
+### Pull the image
 
 ```
-$ sudo docker build -t microsoft/playwright:bionic -f Dockerfile.bionic .
+$ docker pull mcr.microsoft.com/playwright:bionic

-> **NOTE**: The seccomp profile is coming from Jessie Frazelle. It's needed
-> to run Chrome without sandbox.  
-> Using `--ipc=host` is also recommended when using Chrome. Without it Chrome can run out of memory and crash.

-## Playwright on Alpine
+* The seccomp profile is required to run Chrome without sandbox. Thanks to [Jessie Frazelle](https://github.com/jessfraz/dotfiles/blob/master/etc/docker/seccomp/chrome.json).
+* Using `--ipc=host` is also recommended when using Chrome ([Docker docs](https://docs.docker.com/engine/reference/run/#ipc-settings---ipc)). Chrome can run out of memory without this flag.
