These are Docker images used for cross compilation in CI builds (or locally) via the Cross tool.
The Cross tool actually provides its own Docker images, and all Docker images
in this directory are derived from one of them. We provide our own in order
to customize the environment. For example, we need to install some things like
asciidoc in order to generate man pages. We also install compression tools
like xz so that tests for the -z/--search-zip flag are run.
If you make a change to a Docker image, then you can re-build it. cd into the
directory containing the Dockerfile and run:
$ cd x86_64-unknown-linux-musl
$ ./build
At this point, subsequent uses of cross will now use your built image since
Docker prefers local images over remote images. In order to make these changes
stick, they need to be pushed to Docker Hub:
$ docker push burntsushi/cross:x86_64-unknown-linux-musl
Of course, only I (BurntSushi) can push to that location. To make cross use
a different location, then edit Cross.toml in the root of this repo to use
a different image name for the desired target.
