Installing only required playwright packages in existing Docker image about playwright

[mxschmitt]

Can some please explain how to do this in Docker file?

See here: https://playwright.dev/java/docs/browsers#install-system-dependencies

Also, do I need Node.js to run headless browser when using java library?

No, only the Playwright for Java package is needed.

I'm going to close it for now, since this is not a bug / feature request.

@mxschmitt : Is there anyway I can predownload the required dependencies/binaries and keep it in some folder so that I can use it at the time of docker creation.

Or can I use existing playwright docker image to install required dependencies at the time of my java app docker file creation?

Unfortunately not, you need to install the Maven dependencies first and then the Playwright dependencies. Since they contain OS dependencies (apt), you can't cache them.

You could probably create some multi-layer Docker image with only Playwright first and extend from that in order to benefit from caching, so that the whole image does not need to be rebuilt when you change something in your project.

We also have an official Java Docker image, if that helps: https://playwright.dev/java/docs/docker
