rsync Buildkite Plugin

A Buildkite plugin for performing file transfers via rsync. The plugin invokes rsync in the pre or post command phase to provide an artifact-like upload and download capacity.

Examples

Upload a build product directory into a build-specific output directory on a remote store:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post: "-Rrv bin remote:/build/${BUILDKITE_BUILD_NUMBER}"

Upload a glob of files, note that artifact-path extended globbing (eg. path/**/*.log) is not supported:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post: "-Rrv log/*/*.log remote:/build/${BUILDKITE_BUILD_NUMBER}"

${VAR} is interpolated at pipeline-upload time, not step evaluation time. Use $${VAR} to perform step-time interpolation of environment variables:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post: "-Rrv bin remote:/build/$${BUILDKITE_JOB_ID}"

Upload via multiple invocations:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post:
           - "-Rrv bin remote:/build/${BUILDKITE_BUILD_NUMBER}"
           - "-Rrv logs/*/*.txt remote:/build/${BUILDKITE_BUILD_NUMBER}/$${BUILDKITE_JOB_ID}"

Download before a command executes via the pre step:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          pre: "-rv remote:/build/ccache ./ccache"

Ugly Hacks

From man rsync, "Rsync is a fast and extraordinarily versatile file copying tool [...] it offers a large number of options that control every aspect of its behavior and permit very flexible specification."

:trollface:

Rsync does not support creation of nested output directories. Create a nested output directory via repeated "no-op" copies:

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post:
            - "-Rrv --exclude=* . remote:/build/artifacts"
            - "-Rrv --exclude=* . remote:/build/artifacts/${BUILDKITE_BRANCH}"
            - "-Rrv --exclude=* . remote:/build/artifacts/${BUILDKITE_BRANCH}/${BUILDKITE_BUILD_NUMBER}"
            - "-Rrv bin remote:/build/artifacts/${BUILDKITE_BRANCH}/${BUILDKITE_BUILD_NUMBER}"

Create a nested output directory via the "rsync-path trick":

steps:
  - plugins:
      - uw-ipd/rsync#v0.1:
          post: "--rsync-path="mkdir -p /build/artifacts/${BUILDKITE_BRANCH}/${BUILDKITE_BUILD_NUMBER} && rsync" -Rrv bin remote:/build/artifacts/${BUILDKITE_BRANCH}/${BUILDKITE_BUILD_NUMBER}"

Configuration

pre

An rsync argument string, or array of rsync argument strings, to be executed before command.

post

An rsync argument string, or array of rsync argument strings, to be executed after command.
