Chrome running in headless mode in a tiny Alpine image
In the world of webdev, the ability to run quickly end-to-end tests are important. Popular technologies like Puppeteer enable developers to make fun things like testing, automating forms, crawling, generating screenshots, capturing timeline... And there is a secret: some of these features are directly available on Chrome! 🙌

Launching the container using only docker container run -it zenika/alpine-chrome ... will fail with some logs similar to #33.
Please use the 3 others ways to use Chrome Headless.
Launch the container using:
docker container run -it --rm zenika/alpine-chrome and use the --no-sandbox flag for all your commands.
Be careful to know the website you're calling.
Explanation for the no-sandbox flag in a quick introduction here and for More in depth design document here
Launch the container using:
docker container run -it --rm --cap-add=SYS_ADMIN zenika/alpine-chrome
This allows to run Chrome with sandboxing but needs unnecessary privileges from a Docker point of view.
Thanks to ever-awesome Jessie Frazelle seccomp profile for Chrome. This is The most secure way to run this Headless Chrome docker image.
Also available here wget https://raw.githubusercontent.com/jfrazelle/dotfiles/master/etc/docker/seccomp/chrome.json
Launch the container using:
docker container run -it --rm --security-opt seccomp=$(pwd)/chrome.json zenika/alpine-chrome
The default entrypoint runs chromium-browser --headless with some common flags from CHROMIUM_FLAGS set in the Dockerfile.
You can change the CHROMIUM_FLAGS by overriding the environment variable using: docker container run -it --rm --env CHROMIUM_FLAGS="--other-flag ..." zenika/alpine-chrome chromium-browser ...
You can get full control by overriding the entrypoint using: docker container run -it --rm --entrypoint "" zenika/alpine-chrome chromium-browser ...

Hello world!
With tool like "Puppeteer", we can add a lot things with our Chrome Headless.
With some code in NodeJS, we can improve and make some tests.
See the "with-puppeteer" folder for more details. We have to follow the mapping of Chromium => Puppeteer described here.
If you have a NodeJS/Puppeteer script in your src folder named pdf.js, you can launch it using the following command:
docker container run -it --rm -v $(pwd)/src:/usr/src/app/src --cap-add=SYS_ADMIN zenika/alpine-chrome:with-puppeteer node src/pdf.js
With the "font-wqy-zenhei" library, you could also manipulate asian pages like in "screenshot-asia.js"
docker container run -it --rm -v $(pwd)/src:/usr/src/app/src --cap-add=SYS_ADMIN zenika/alpine-chrome:with-puppeteer node src/screenshot-asia.js
These websites are tested with the following supported languages:
- Chinese (with
https://m.baidu.com) - Japanese (with
https://www.yahoo.co.jp/) - Korean (with
https://www.naver.com/)
According to puppeteer official doc you can not test a Chrome Extension in headleass mode. You need a display available, that's where Xvfb comes in.
See the "with-puppeteer-xvfb" folder for more details. We have to follow the mapping of Chromium => Puppeteer described here.
Assuming you have a NodeJS/Puppeteer script in your src folder named extension.js, and the unpacked extension in the chrome-extension folder, you can launch it using the following command:
docker container run -it --rm -v $(pwd)/src:/usr/src/app/src --cap-add=SYS_ADMIN zenika/alpine-chrome:with-puppeteer-xvfb node src/extension.js
The extension provided will change the page background in red for every website visited. This demo will load the extension and take a screenshot of the icanhazip.com website.
Like "Puppeteer", we can do a lot things using "Playwright" with our Chrome Headless.
Go to the with-playwright folder and launch the following command:
docker container run -it --rm -v $(pwd)/src:/usr/src/app/src --cap-add=SYS_ADMIN zenika/alpine-chrome:with-playwright node src/useragent.js
A example-chromium.png file will be created in your with-playwright/src folder.
By default, this image works with WebGL.
If you want to disable it, make sure to add --disable-gpu when launching Chromium.
docker container run -it --rm --cap-add=SYS_ADMIN -v $(pwd):/usr/src/app zenika/alpine-chrome --screenshot --hide-scrollbars https://webglfundamentals.org/webgl/webgl-fundamentals.html
docker container run -it --rm --cap-add=SYS_ADMIN -v $(pwd):/usr/src/app zenika/alpine-chrome --screenshot --hide-scrollbars https://browserleaks.com/webgl
ChromeDriver is a separate executable that Selenium WebDriver uses to control Chrome. You can use this image as a base for your Docker based selenium tests. See Guide for running Selenium tests using Chromedriver.
Selenoid is a powerful implementation of Selenium hub using Docker containers to launch browsers.
Even if it used to run browsers in docker containers, it can be quite useful as lightweight Selenium replacement.
with-selenoid image is a self sufficient selenium server, chrome and chromedriver installed.
You can run it with following command:
docker container run -it --rm --cap-add=SYS_ADMIN -p 4444:4444 zenika/alpine-chrome:with-selenoid -capture-driver-logs
And run your tests against http://localhost:4444/wd/hub
One of the use-cases might be running automation tests in the environment with restricted Docker environment
like on some CI systems like GitLab CI, etc. In such case you may not have permissions for --cap-add=SYS_ADMIN
and you will need to pass the --no-sandbox to chromedriver.
See more selenoid docs
We can run the container as root with this command:
docker container run --rm -it --entrypoint "" --user root zenika/alpine-chrome sh
Some examples are available on the examples directory:
- 🐳 docker-compose to launch a chrome calling a nginx server in the same docker-compose
- ☸️ kubernetes to launch a pod with a headless chrome
- 🖥 x11 to experiment this image with a X11 server.
