https://github.com/bazelbuild/bazel-toolchains is a repository where Google hosts Bazel toolchain configs. These configs are required to configure Bazel to issue commands that will execute inside a Docker container via a remote execution environment.
These toolchain configs include:
- C/C++ CROSSTOOL file,
- BUILD file with toolchain rules, and
- wrapper scripts.
This repository also hosts the skylark rule used to generate toolchain configs.
