What are the steps to containerize a Playwright project using Docker and how to troubleshoot common issues?


Here's a quick guide on how to dockerize your Playwright project and troubleshoot any issues you might face.

First, create a Dockerfile for your project. This file is used to build a Docker image with all the necessary dependencies and configurations for your project.

FROM node:14
COPY . /app
RUN npm install --production

If you run into memory usage issues or crashes when running Chromium inside the container, use the --ipc=host flag when launching Chromium. This allows Chromium to share its inter-process communication (IPC) namespace with the host system and prevents out-of-memory errors.

If you face other issues like zombie processes or special treatment for processes with PID=1, consider using --init flag or installing dumb-init in your container.

Once your Dockerfile is ready, build an image with this command:

docker build -t my-playwright-project .

After building the image, you can run a container based on that image using docker run. Remember to expose any required ports and mount volumes if needed.

If you encounter specific issues during this process or need further assistance, please provide more details about the problems you are facing.

This guide provides a general guideline for dockerizing a Playwright project. The specific configurations and troubleshooting steps may vary depending on your project's requirements and the issues you encounter.
