This plugin will assist you in triggering pipelines by watching folders in your monorepo.
Check out this post to learn How to set up Continuous Integration for monorepo using Buildkite.
If the version number is not provided then the most recent version of the plugin will be used. Do not use version number as master or any branch names.

wait: trueThis will run the script provided to determine the folder changes. Depending on your use case, you may want to determine the point where the branch occurs https://stackoverflow.com/questions/1527234/finding-a-branch-point-with-git and perform a diff against the branch point.

Default: git diff --name-only HEAD~1
diff: ./diff-against-last-successful-build.sh
#!/bin/bash
set -ueo pipefail
LAST_SUCCESSFUL_BUILD_COMMIT="$(aws s3 cp "${S3_LAST_SUCCESSFUL_BUILD_COMMIT_PATH}" - | head -n 1)"
git diff --name-only "$LAST_SUCCESSFUL_BUILD_COMMIT"diff: ./diff-against-last-built-tag.sh
#!/bin/bash
set -ueo pipefail
LATEST_BUILT_TAG=$(git describe --tags --match foo-service-* --abbrev=0)
git diff --name-only "$LATEST_TAG"This controls the pipeline interpolation on upload, and defaults to true.
If set to false it adds --no-interpolation to the buildkite pipeline upload,
to avoid trying to interpolate the commit message, which can cause failures.
The object values provided in this configuration will be appended to env property of all steps or commands.
Add log_level property to set the log level. Supported log levels are debug and info. Defaults to info.
steps:
- label: "Triggering pipelines"
plugins:
- chronotc/monorepo-diff#v2.1.1:
diff: "git diff --name-only HEAD~1"
log_level: "debug" # defaults to "info"
watch:
- path: "foo-service/"
config:
trigger: "deploy-foo-service"Declare a list of
- path: app/cms/
config: # Required [trigger step configuration]
trigger: cms-deploy # Required [trigger pipeline slug]
- path:
- services/email
- assets/images/email
config:
trigger: email-deployIf the path specified here in the appears in the diff output, a trigger step will be added to the dynamically generated pipeline.yaml
A list of paths can be provided to trigger the desired pipeline. Changes in any of the paths will initiate the pipeline provided in trigger.
A path can also be a glob pattern. For example specify path: "**/*.md" to match all markdown files.
Configuration supports 2 different step types.
The configuration for the trigger step https://buildkite.com/docs/pipelines/trigger-step
By default, it will pass the following values to the build attributes unless an alternative values are provided
- path: app/cms/
config:
trigger: cms-deploy
build:
commit: $BUILDKITE_COMMIT
branch: $BUILDKITE_BRANCHDefault: true
By setting wait to true, the build will wait until the triggered pipeline builds are successful before proceeding
Currently supports a list of commands you wish to execute after the watched pipelines have been triggered
hooks:
- command: upload unit tests reports
- command: echo successsteps:

plugins:
- chronotc/monorepo-diff#v2.1.1:

watch:

config:
command: "netlify --production deploy"
label: ":netlify: Deploy to production"
agents:
queue: "deploy"
env:
- FOO=barThere is currently limited support for command configuration. Only the command property can be provided at this point in time.
Using commands, it is also possible to use this to upload other pipeline definitions
- path: frontend/
config:
command: "buildkite-agent pipeline upload ./frontend/.buildkite/pipeline.yaml"
- path: infrastructure/
config:
command: "buildkite-agent pipeline upload ./infrastructure/.buildkite/pipeline.yaml"
- path: backend/
config:
command: "buildkite-agent pipeline upload ./backend/.buildkite/pipeline.yaml"Please read contributing guide.
