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_v4_api_url: Optional. If you use a non-public GitHub deployment then you can set your API URL for graphql calls 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, check detects final releases and put publishes final releases (as opposed to pre-releases). If false, check will ignore final releases, and put will publish pre-releases if pre_release is set to true
pre_release: Optional. Default false. When set to true, check detects pre-releases, and put will produce pre-releases (if release is also set to false). If false, only non-prerelease releases will be detected and published.

note: if both release and pre_release are set to true, put produces final releases and check detects both pre-releases and releases. In order to produce pre-releases, you must set pre_release to true and release to false.
note: if both release and pre_release are set to false, put will still produce final releases.
note: releases must have semver compliant tags to be detected.
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.
semver_constraint: Optional. If set, constrain the returned semver tags according to a semver constraint, e.g. "~1.2.x", ">= 1.2 < 3.0.0 || >= 4.2.3". Follows the rules outlined in https://github.com/Masterminds/semver#checking-version-constraints.
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.
order_by: Optional. One of [version, time]. Default version. Selects whether to order releases by version (as extracted by tag_filter) or by time. See check behavior described below for details.

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
    generate_release_notes: true

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.

Lists releases, sorted either by their version or time, depending on the order_by source option.

When sorting by version, the version is extracted from the git tag using the tag_filter source option. Versions are compared using semver semantics if possible.

When sorting by time and a release is published, it uses the publication time, otherwise it uses the creation time.

The returned list contains an object of the following format for each release (with timestamp in the RFC3339 format):

{
    "id": "12345",
    "tag": "v1.2.3",
    "timestamp": "2006-01-02T15:04:05.999999999Z"
}

When check is given such an object as the version parameter, it returns releases from the specified version or time on. Otherwise it returns the release with the latest version or time.

`in`: Fetch assets from a release.

Fetches artifacts from the requested release.

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.
timestamp containing the publish or creation timestamp for the release in RFC 3339 format.
commit_sha containing the commit SHA the tag is pointing to.
url containing the HTMLURL for the release being fetched.

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.
generate_release_notes: Optional. Causes GitHub to autogenerate the release notes when creating a new release, based on the commits since the last release. If body is specified, the body will be pre-pended to the automatically generated notes. Has no effect when updating an existing release. Defaults to false.

Development

Prerequisites

golang is required - version 1.15.x is tested; earlier versions may also work.
docker is required - version 17.06.x is tested; earlier versions may also work.

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 --target tests --build-arg base_image=concourse/resource-types-base-image-static:latest .
