Hello @lawRathod, Thank you for creating this issue and We'll look into it :)

Hi @lawRathod,

Just to clarify — the actions/setup-node GitHub Action does not build Node.js from source, nor does it support customizing how Node.js is built or linked. Its primary role is to download and configure official pre-built Node.js binaries from the Node.js project for use in GitHub Actions workflows. These binaries are built against glibc, which is the standard C library on most major Linux distributions.

As a result, we don’t support alternative C libraries like musl, which is used in Alpine Linux.

That said, the Node.js project does offer an official Alpine container image, although it includes an unofficial Node.js build internally. These unofficial builds are statically linked against musl and may suit your needs.

If you're targeting Alpine or require statically linked binaries with musl, we recommend checking out the builds available at unofficial-builds.nodejs.org.

Hope this helps!

Hi @lawRathod, a gentle reminder regarding this issue, If you need further clarification or assistance, Please let us know.

Hii @mahabaleshwars!! Thanks for your reply.

I understand the problem, I spent a bit of time before realizing what was going on with my setup. Thanks for the resources, I thinking changing my workflow container is easiest to resolve this. Maybe a warning somewhere in docs would make sense and help users?

I will close this issue now. :)
