Dennis Kempin b3ccebbf3d Improve build / test documentation 
A lot of the information was outdated. The new guide prioritizes
building for linux and testing on linux as the default workflow
for crosvm.

CrosVM Continuous Integration

Crosvm has a complex set of dependencies and requirements on the host machine to successfully build and run test cases. To allow for consistent testing in our continuous integration system (kokoro) and reproduction of those tests locally, we provide docker containers containing the build toolchain and a VM for testing.

Implementation Overview

Directories:

  • ci/build_environment: Contains tooling for building the dependencies of crosvm.
  • ci/crosvm_aarch64_builder: An x86 docker image to cross-compile for aarch64 and test with user-space emulation.
  • ci/crosvm_base: Docker image shared by crosvm_builder and crosvm_aarch64_builder
  • ci/crosvm_builder: A native docker image for building and testing crosvm
  • ci/crosvm_test_vm: Dockerfile to build the VM included in the builder containers.
  • ci/kokoro: Configuration files and build scripts used by Kokoro to run crosvm tests.

Scripts:

  • ci/aarch64_builder: Script to start the crosvm_aarch64_builder container
  • ci/builder: Script to start the crosvm_builder container
  • ci/run_container.sh: Implementation behind the above scripts.
  • test_runner.py: Implementation behind the ./test_all script.

Building and uploading a new version of builders

The docker images for all builders can be built with make and uploaded with make upload. Of course you need to have docker push permissions for gcr.io/crosvm-packages/ for the upload to work.
