This can be +helpful to test environments different from your local system. First you will +need to install Docker on a Linux, Windows, or macOS system (typically Linux +will be much faster than Windows or macOS because the latter use virtual +machines to emulate a Linux environment). To enter interactive mode which will +start a bash shell in the container, run `src/ci/docker/run.sh --dev <IMAGE>` +where `<IMAGE>` is one of the directory names in `src/ci/docker` (for example +`x86_64-gnu` is a fairly standard Ubuntu environment). + +The docker script will mount your local Rust source tree in read-only mode, +and an `obj` directory in read-write mode. All of the compiler artifacts will +be stored in the `obj` directory. The shell will start out in the `obj` +directory. From there, you can run `../src/ci/run.sh` which will run the build +as defined by the image. + +Alternatively, you can run individual commands to do specific tasks. For +example, you can run `python3 ../x.py test src/test/ui` to just run UI tests. +Note that there is some configuration in the [`src/ci/run.sh`] script that you +may need to recreate. Particularly, set `submodules = false` in your +`config.toml` so that it doesn't attempt to modify the read-only directory. + +Some additional notes about using the Docker images: + +- Some of the std tests require IPv6 support. Docker on Linux seems to have it + disabled by default. Run the commands in [`enable-docker-ipv6.sh`] to enable + IPv6 before creating the container. This only needs to be done once. +- The container will be deleted automatically when you exit the shell, however + the build artifacts persist in the `obj` directory. If you are switching + between different Docker images, the artifacts from previous environments + stored in the `obj` directory may confuse the build system. Sometimes you + will need to delete parts or all of the `obj` directory before building + inside the container. +- The container is bare-bones, with only a minimal set of packages. You may + want to install some things like `apt install less vim`. +- You can open multiple shells in the container. First you need the container + name (a short hash), which is displayed in the shell prompt, or you can run + `docker container ls` outside of the container to list the available + containers. With the container name, run `docker exec -it <CONTAINER> + /bin/bash` where `<CONTAINER>` is the container name like `4ba195e95cef`. + +[Docker]: https://www.docker.com/ +[`src/ci/docker`]: https://github.com/rust-lang/rust/tree/master/src/ci/docker +[`src/ci/docker/run.sh`]: https://github.com/rust-lang/rust/blob/master/src/ci/docker/run.sh +[`src/ci/run.sh`]: https://github.com/rust-lang/rust/blob/master/src/ci/run.sh +[`enable-docker-ipv6.sh`]: https://github.com/rust-lang/rust/blob/master/src/ci/scripts/enable-docker-ipv6.sh |
