This is an Example to build only specific MicroServices depending on the code changes in a MonoRepo with a single Cloud Build Trigger.
This Repo has
- A Base CloudBuild.yaml which acts as a trigger for the CI pipeline.
- Two Microservices service-one and service-two with their respective manifests file and cloud build file to build that specific microservice.
Once the CloudBuild is Triggered, The CloudBuild first identifies the directory changes from a git diff and writes to a local text file to pass on the next step.
In the next step, the Text file is read and the cloudbuild file path is built with the format as /cloudbuild.yaml. Then the builds are submitted via gcloud Options which would then do a build for each of the specific Microservice.
