docker-images
Docker images for cross compiling prebuilt binaries for Node.js. Used by prebuildify-cross.
About
All images include node, npm, npx and a preconfigured build toolchain suitable for node-gyp and prebuildify. For example:
> docker run --rm -it ghcr.io/prebuild/alpine node -v
v14.17.4
Images are tagged with a major, minor and full version as well as latest. For example, use the following to pin to major version 1:
FROM ghcr.io/prebuild/alpine:1Versioning guarantees
Within a major version range, we will not change toolchains, environment variables, working directories, users and more. However, the Node.js version will change without notice. We use Node.js LTS (at the time of building images) for a light maintenance effort. This is okay because prebuildify can target (the headers of) older Node.js versions while itself running on a newer version.
We've yet to align Python versions (#15). A next major will use Python 3.
Images that are based on dockcross (see below) may inadvertently introduce breaking changes because dockcross does not use semantic versions (dockcross/dockcross#399) and does not maintain a changelog that would allow us to easily categorize changes and then tag our images accordingly. If this concerns you we recommend pinning to an exact version (x.x.x) which we treat as immutable.

centos7-devtoolset7
Compile in CentOS 7, as a better alternative to (commonly) Ubuntu 16.04 on Travis or GitHub Actions. Makes prebuilds compatible with Debian 8, Ubuntu 14.04, RHEL 7, CentOS 7 and other Linux flavors with an old glibc.
The neat thing about this is that you get to compile with gcc 7 but glibc 2.17, so binaries are compatible for [among others] Ubuntu 14.04 and Debian 8.
The RHEL folks put in a ton of work to make the devtoolsets work on their older base systems (libc mainly), which involves shipping a delta library that contains the new stuff that can be statically linked in where it's used. We use this method for building Node binary releases.
Preconfigures prebuildify to tag prebuilds with the libc flavor, to set them apart from musl prebuilds, e.g. linux-x64/node.glibc.node.
alpine
Compile in Alpine, which uses musl instead of glibc and therefore can't run regular linux prebuilds. Worse, it sometimes does successfully load such a prebuild during npm install - which prevents a compilation fallback from kicking in - and then segfaults at runtime. You can fix this situation in two ways: by shipping an alpine prebuild and/or by shipping a centos7-devtoolset7 prebuild, because the latter will be skipped in Alpine thanks to the glibc tag.
Preconfigures prebuildify to tag prebuilds with the libc flavor, to set them apart from glibc prebuilds, e.g. linux-x64/node.musl.node.
