Bazel Commands

bazel_build_ci.sh

# `services` is a directory with application services that are packages as docker containers.
# It has source codes as well as BUILD.bazel files that define container images for each service.
# We ask git to give us a list of changed files in services directory which is then piped into
# bazel query comand that will give you all container image targets that should be rebuild.
git diff --name-only services ${PREVIOUS_REVISION} | xargs -I{dep} bazel query 'kind("_app_layer", rdeps(//services, {dep}))'

# building changed packages
bazelisk build `git diff --name-only ${PREVIOUS_REVISION} | xargs -I{dep} -P8 bazelisk query 'rdeps(//..., {dep})' --output package`

# publishing docker container image with current revision
