Docker

Dockerfile.focal can be used to run Playwright scripts in Docker environment. These image includes all the dependencies needed to run browsers in a Docker container, and also include the browsers themselves.

Usage

This image is published on Docker Hub.

Pull the image

or pinned to a specific Playwright version (recommended). Replace 1.15.0 with your Playwright version:

Run the image

By default, the Docker image will use the root user to run the browsers. This will disable the Chromium sandbox which is not available with root. If you run trusted code (e.g. End-to-end tests) and want to avoid the hassle of managing separate user then the root user may be fine. For web scraping or crawling, we recommend to create a separate user inside the Docker container and use the seccomp profile.

End-to-end tests

On trusted websites, you can avoid creating a separate user and use root for it since you trust the code which will run on the browsers.

Crawling and scraping

On untrusted websites, it's recommended to use a separate user for launching the browsers in combination with the seccomp profile. Inside the container or if you are using the Docker image as a base image you have to use adduser for it.

seccomp_profile.json is needed to run Chromium with sandbox. This is a default Docker seccomp profile with extra user namespace cloning permissions:

[
{
"comment": "Allow create user namespaces",
"names": [
"clone",
"setns",
"unshare"
],
"action": "SCMP_ACT_ALLOW",
"args": [],
"includes": {},
"excludes": {}
}
]
note

Using --ipc=host is 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.
