You can find APIs and Integrations in their own sections in the horizontal menu bar at the top of the page.
Plugins can be used in pipeline command steps to access a library of commands or perform actions.
To add a plugin to a command step, use the
plugins attribute. The
plugins attribute accepts an array, so you can add multiple plugins to the same step.
When multiple plugins are listed in the same step, they will run in the order of the hooks, and within each hook, in the order they were listed in the step.
steps: - command: yarn install && yarn run test plugins: - shellcheck#v1.1.2: files: scripts/*.sh - docker#v3.3.0: image: node workdir: /app
Always specify a tag or commit (for example,
v1.2.3) to prevent the plugin changing unexpectedly, and to prevent stale checkouts of plugins on your agent machines.
Not all plugins require a
command attribute, for example:
steps: - plugins: - docker-login#v2.0.1: username: xyz - docker-compose#v3.0.3: build: app image-repository: index.docker.io/myorg/myrepo
Although there's no
command attribute in the above example, this is still
considered a command step, so all command attributes are available for use.
It is possible to define multiple hooks of the same type in both a plugins and the agent hooks location. See job lifecycle hooks for the overall order of hooks, and the relative order of invocation for each location.
Plugins are configured using attributes in your pipeline YAML configuration. The simplest plugin is one that accepts no configuration, such as the Library Example plugin:
steps: - label: ":books:" plugins: - library-example#v1.0.0: ~
More commonly, plugins accept various configuration options. For example, the Docker plugin requires the attribute
image, and we have also included the optional
steps: - command: yarn install && yarn run test plugins: - docker#v3.3.0: image: node workdir: /app
More advanced plugins, such as Docker Compose plugin, are designed to be used multiple times in a pipeline, using the build's meta-data store to share information from one step to the next. This means that you can build a Docker image in the first step of a pipeline and refer to that image in subsequent steps.
steps: # Prebuild the app image, upload it to a registry for later steps - label: ":docker: Build" plugins: - docker-compose#v3.0.3: build: app image-repository: index.docker.io/org/repo - wait # Use the app image built above to run concurrent tests - label: ":docker: Test %spawn" command: test.sh parallelism: 25 plugins: - docker-compose#v3.0.3: run: app
See each plugin's readme for a list of which options are available.
There are three main sources of plugins:
- Buildkite-maintained plugins
- Non-Buildkite plugins hosted on GitHub
- Local, private, and non-GitHub plugins
Buildkite-maintained plugins can be found in the Buildkite Plugins GitHub organization. When using these plugins, you can refer to them using only the name of the plugin, for example:
steps: - command: yarn install && yarn run test plugins: # Resolves to https://github.com/buildkite-plugins/docker-buildkite-plugin - docker#v3.3.0: image: node workdir: /app
Non-Buildkite plugins hosted on GitHub require you to include the organization name as well as the plugin name, for example:
steps: - command: yarn install && yarn run test plugins: # Resolves to https://github.com/my-org/docker-buildkite-plugin - my-org/docker#v3.3.0: image: node workdir: /app
Local, private, and non-GitHub plugins can be used by specifying the fully qualified Git URL, for example:
steps: - command: yarn install && yarn run test plugins: - https://bitbucket.com/my-org/my-plugin.git#v1.0.0: ~ - ssh://email@example.com/my-org/my-plugin.git#v1.0.0: ~ - file:///a-local-path/my-plugin.git#v1.0.0: ~
To avoid a plugin's git tag contents being changed, you can use the commit SHA of the tag, for example using
docker-compose#287293c4 in the following example:
steps: - command: echo 'Hello World' plugins: - docker-compose#287293c4: run: app
To test plugins you can reference the branch, for example:
steps: - command: echo 'Hello World' plugins: - docker-compose#feature/add-new-feature: run: app
