Thanks for tagging me @rubenf.

Answer To preinstall binaries in Windmill, you have two main approaches: extending the base Docker image or using init scripts. 1. Extending the base Docker image: You can create a custom Docker image by extending the base image provided by Windmill and then use apt or other package managers to install the binaries you need. Here’s an example Dockerfile snippet for installing Node.js and npm packages:

    FROM ghcr.io/windmill-labs/windmill:main
    RUN apt-get update && apt install -y nodejs npm
    RUN npm install -g your-package
    CMD ["windmill"]

    FROM ghcr.io/windmill-labs/windmill:main
    RUN apt-get update && apt install -y nodejs npm
    RUN npm install -g your-package
    CMD ["windmill"]

(1) 2. Using init scripts: Init scripts are executed at the beginning when the worker starts, allowing you to install binaries or set initial configurations without modifying the base image. You can set these scripts from the Worker Management UI at the worker group level. Here is an example init script for installing Playwright via pip:

    pip install playwright
    export PATH=$PATH:/tmp/.local/bin
    playwright install
    playwright install-deps

    pip install playwright
    export PATH=$PATH:/tmp/.local/bin
    playwright install
    playwright install-deps

(2) (3) These binaries are then available for use in your Windmill scripts and flows. Remember that the init scripts are executed every time a worker starts, while extending the base Docker image is a one-time setup that persists across worker restarts.
