GitHub Releases Resource

Fetches and creates versioned GitHub resources.

If you're seeing rate limits affecting you then please add a token to the source configuration. This will increase your number of allowed requests.

Source Configuration

• owner: Required. The GitHub user or organization name for the repository that the releases are in.

• repository: Required. The repository name that contains the releases.

• access_token: Optional. Used for accessing a release in a private-repo during an in and pushing a release to a repo during an out. The access token you create is only required to have the repo or public_repo scope.

• github_api_url: Optional. If you use a non-public GitHub deployment then you can set your API URL here.

• github_uploads_url: Optional. Some GitHub instances have a separate URL for uploading. If github_api_url is set, this value defaults to the same value, but if you have your own endpoint, this field will override it.

• insecure: Optional. Default false. When set to true, concourse will allow insecure connection to your github API.

• release: Optional. Default true. When set to true, put produces release and check detects releases. If false, put and check will ignore releases. Note that releases must have semver compliant tags to be detected.

• pre_release: Optional. Default false. When set to true, put produces pre-release and check detects prereleases. If false, only non-prerelease releases will be detected and published. Note that releases must have semver compliant tags to be detected. If release and pre_release are set to true, put produces release and check detects prereleases and releases.

• drafts: Optional. Default false. When set to true, put produces drafts and check only detects drafts. If false, only non-draft releases will be detected and published. Note that releases must have semver compliant tags to be detected, even if they're drafts.

• tag_filter: Optional. If set, override default tag filter regular expression of v?([^v].*). If the filter includes a capture group, the capture group is used as the release version; otherwise, the entire matching substring is used as the version.

Example

- name: gh-release
  type: github-release
  source:
    owner: concourse
    repository: concourse
    access_token: abcdef1234567890

- get: gh-release

- put: gh-release
  params:
    name: path/to/name/file
    tag: path/to/tag/file
    body: path/to/body/file
    globs:
    - paths/to/files/to/upload-*.tgz

To get a specific version of a release:

- get: gh-release
  version: { tag: 'v0.0.1' }

To set a custom tag filter:

- name: gh-release
  type: github-release
  source:
    owner: concourse
    repository: concourse
    tag_filter: "version-(.*)"

Behavior

check: Check for released versions.

Releases are listed and sorted by their tag, using semver semantics if possible. If version is specified, check returns releases from the specified version on. Otherwise, check returns the latest release.

in: Fetch assets from a release.

Fetches artifacts from the given release version. If the version is not specified, the latest version is chosen using semver semantics.

Also creates the following files:

• tag containing the git tag name of the release being fetched.
• version containing the version determined by the git tag of the release being fetched.
• body containing the body text of the release.
• commit_sha containing the commit SHA the tag is pointing to.

Parameters

• globs: Optional. A list of globs for files that will be downloaded from the release. If not specified, all assets will be fetched.

• include_source_tarball: Optional. Enables downloading of the source artifact tarball for the release as source.tar.gz. Defaults to false.

• include_source_zip: Optional. Enables downloading of the source artifact zip for the release as source.zip. Defaults to false.

out: Publish a release.

Given a name specified in name, a body specified in body, and the tag to use specified in tag, this creates a release on GitHub then uploads the files matching the patterns in globs to the release.

Parameters

• name: Required. A path to a file containing the name of the release.

• tag: Required. A path to a file containing the name of the Git tag to use for the release.

• tag_prefix: Optional. If specified, the tag read from the file will be prepended with this string. This is useful for adding v in front of version numbers.

• commitish: Optional. A path to a file containing the commitish (SHA, tag, branch name) that the release should be associated with.

• body: Optional. A path to a file containing the body text of the release.

• globs: Optional. A list of globs for files that will be uploaded alongside the created release.

Development

Prerequisites

• golang is required - version 1.9.x is tested; earlier versions may also work.
• docker is required - version 17.06.x is tested; earlier versions may also work.
• godep is used for dependency management of the golang packages.

Running the tests

The tests have been embedded with the Dockerfile; ensuring that the testing environment is consistent across any docker enabled platform. When the docker image builds, the test are run inside the docker container, on failure they will stop the build.

Run the tests with the following command:

docker build -t github-release-resource .
