cross-rs and git - how to make a local ~/.gitconfig and ~/.git-credentials available to a cross-rs container for cross compiling
Raw
HOWTO.md

Move the files to ~/.config/git

mkdir -p ~/.config/git
mv ~/.gitconfig ~/.config/git/config
mv ~/.git-credentials ~/.config/git/credentials
ln -s ~/.config/git/config ~/.gitconfig
ln -s ~/.config/git/credentials ~/.git-credentials

That keeps your current config in place and working while placing your files in a logical place for access (in fact, if you set XDG_CONFIG_HOME to ~/.config you won't need to do the symbolic links).

Create a Cross.toml file somewhere

I put it in my home directory and then set CROSS_CONFIG to point to it - but you'll need to figure out the best approach for you.

Simply add the following lines to that file

[build.env]
passthrough = ["XDG_CONFIG_HOME=/home/your-user-id/.config"]
volumes = ["/home/your-user-id/.config=/home/your-user-id/.config"]

That gives Cross access to your .config folder and sets the XDG_CONFIG_HOME environment variable appropriately within the container, giving GIT access to your host config.
