Builder image based in Arch Linux

This is a Docker image, based, and pretty close to the Docker Arch Linux latest image.

Only changes are running pacman -Sy to update the repositories, and installing base-devel and sudo.

base-devel is needed for compilation and building packages. It provides things such as needed binaries for makepkg. sudo is needed because makepkg refuses to run for the root user. This can be solved by patching the corresponding code in /usr/bin/makepkg, but that would require constant upkeep by my part.

Instead, this image creates a new user called builder and adds it to sudoers. Then, it creates the paths /builds/ and /builds/output and adds rights to it for the builder user.

It also configures makepkg so that all built packages will be sent to /builds/output/. This is useful to automatically get all the built packages back.

It does not contain yay or any other AUR helper.

Usage example

For the sake of keeping it brief (and because you can check the wonderful Arch Linux wiki on how to make PKGBUILD files). This is an example package: https://gist.github.com/Sighery/636a4cb05a59e12727ab08785a1d35dd

You'd use it by running (either with sudo if you run docker with sudo, or without) the following command:

sudo bash builder.sh

More info on what that script does here: https://stackoverflow.com/a/51186557

Basically it will build the image, create it, and then copy the output files from it back into your host ./outputs/.

Then you can install, or release your built packages. For installing:

sudo pacman -U outputs/package-name-1.0.0-1-any.pkg.tar.xz
