pkg-fetch
Changes
This fork contains Valetudo-specific changes to the upstream pkg-fetch
No ICU
Since space is limited in embedded devices, this fork is built with '--without-intl'
UPX Support
UPX is supported
Static-linking only
Since the whole point of using pkg is to have a binary that runs everywhere, we're doing static linking only.
Linux-only
Unless some Windows armv7 embedded machine magically appears somewhere, this will be linux-only.
Optimized for size
-Os
Skip bundled payload
This actually isn't a feature of this fork but just mainline pkg.
By setting the PKG_EXECPATH environment variable to PKG_INVOKE_NODEJS, the payload gets ignored and you'll end up
with the nodejs runtime which can then be used for other purposes
How to Use
Fortunately, you can vendor your own pkg nodejs base binaries by using the PKG_CACHE_PATH environment variable to point
to a directory that is part of your codebase. e.g. cross-env PKG_CACHE_PATH=./build_dependencies/pkg pkg --targets node16-linuxstatic-arm64 .
How to build
Building the docker images will also build the nodejs binary.
Build the runtime
armv7
docker build -t valetudo-pkg-fetch-armv7 --build-arg HOST_ARCH=i686 --build-arg TARGET_TRIPLE=armv7l-linux-musleabihf --build-arg PKG_FETCH_OPTION_a=armv7 --build-arg PKG_FETCH_OPTION_n=node18 --build-arg PKG_FETCH_OPTION_p=linuxstatic -f .\Dockerfile.alpine .
aarch64
docker build -t valetudo-pkg-fetch-aarch64 --build-arg HOST_ARCH=x86_64 --build-arg TARGET_TRIPLE=aarch64-linux-musl --build-arg PKG_FETCH_OPTION_a=arm64 --build-arg PKG_FETCH_OPTION_n=node18 --build-arg PKG_FETCH_OPTION_p=linuxstatic -f .\Dockerfile.alpine .
Create a container based on that image
docker create valetudo-pkg-fetch-armv7:latest
Pull the files
docker cp id_from_previous_command:/root/pkg-fetch/dist/ .
