How to run a pipeline step only when pushing to a new branch?
2021-01-07
GitHub sends push hook when pushing to a new branch and merging a PR. How can we distinguish between them?
We are running integration test by triggering a downstream build when a PR is merged into specific branches. In the downstream repository, we pull all the docker images which has been built and pushed from upstream. The thing is we also used the drone-convert-pathschanged to only publish what modules has been changed.
So, what happens when pushing to a new release-*
branch?
How to trigger build steps based on modified directory?

Using monorepo with multiple micro services, every single commit will trigger a full lint/test/build/publish for every service. What can I do to limit the scope?
To do that, we can use git diff
to show changes between commits:
1 if [[ -n "${DRONE_PULL_REQUEST}" ]]; then 2 most_recent_before="origin/${DRONE_TARGET_BRANCH}" 3 elif [[ "${DRONE_BUILD_EVENT}" = "push" && ("${DRONE_COMMIT_BRANCH}" = "master" || "${DRONE_COMMIT_BRANCH}" = "release-"*) ]]; then 4 if [[ "${DRONE_COMMIT_BEFORE}" = "$zero" ]]; then 5 exit 0 6 else 7 most_recent_before="${DRONE_COMMIT_BEFORE}" 8 fi 9 fi 10 modified_files=$(git --no-pager diff --name-only "${DRONE_COMMIT_SHA}".."${most_recent_before}");
