# Note that the hostnames are parsed and trigger specific behavior for different use cases.
# The following parts have a special meaning:
#
# - bk: This is a production VM running the Buildkite agent.
# - pipeline: This is a special production VM that only runs pipeline setup
#               scripts.
# - testing: This is a shared VM that can be used by project members for
#              experiments. It does not run the Buildkite agent.
# - trusted: This is a special production VM that has additional access to
#              secrets.
# - worker: This is a worker VM running normal CI jobs.
