bosh-release-resource

license build dockerhub

A Concourse resource for working with versions of a BOSH release. Specifically focused on support for non-bosh.io releases, private release repositories, version constraints, dev releases, and finalize-release tasks.

Source Configuration

  • uri - location of the BOSH release git repository
  • branch - the branch to use (optional unless using out; uses default remote branch)
  • dev_releases - set to true to create dev releases from every commit
  • name - a specific release name to use (default is name from config/final.yml)
  • private_config - a hash of settings which will be serialized to config/private.yml for in/out
  • private_key - a SSH private key when using private git repositories
  • version - a supported version constraint (e.g. 2.x, >= 2.3.4, >2.3.2, <3)

Operations

check

Get the latest versions of the release.

When dev_releases is enabled, the version will be in the format of ((version))-dev.((commit-date-utc))+commit.((short-commit-hash)). The version number is an incremented patch from the latest final version (as of the referenced commit), followed by the commit-based, pre-release data. For example, if the last final release was 5.0.0 and the last commit was made on 2018-06-13 in dd7c33e1d... the version would be 5.0.1-dev.20180613T040837Z.commit.dd7c33e1d).

Version:

  • version - release version

in

Get a specific version of the release.

Parameters:

  • tarball - create a release tarball (default true)
  • tarball_name - file name to use for the tarball (default {{.Name}}-{{.Version}}.tgz)

Resource:

  • name - release name
  • release.tgz - source release tarball
  • version - release version

Metadata:

  • bosh - version of bosh CLI used to create the tarball
  • time - timestamp when the tarball was created

out

Create a new version of the release from an existing tarball or repository checkout.

Parameters:

  • repository - path to a repository checkout from which to create a release (one of repository or tarball must be configured)
  • tarball - path to an existing release tarball to finalize (one of repository or tarball must be configured)
  • version - path to the file with contents of a specific version to use
  • commit_file - path to the file with contents of a commit message (default message Version {version})
  • author_name - full name to use as commit author (default CI Bot)
  • author_email - email address to use as commit author (default ci@localhost)
  • rebase - enable automatic rebasing if there are conflicts on push (default false)
  • skip_tag - disable creating an annotated tag pointing to the commit the release tarball was created with (default false)

Metadata:

  • bosh - version of bosh CLI used to finalize the release
  • commit - commit reference where the new version was finalized

create-dev-release

The create-dev-release script may be used to create a release tarball from a clone in the current working directory. See create-dev-release.yml for an example task config.

Arguments:

  • Output directory - for creating the release tarball

load-release-notes

The load-release-notes script may be used to output release notes for a given release version from a clone in the current working directory. See load-release-notes.yml for an example task config. Release notes are checked in the following order...

  • locally-committed release notes in releases/{name}/{name}-{version}.md
  • GitHub release notes for tags v{version} or {version} (based on the clone's remote origin)

Arguments:

  • Output path - for writing the release notes contents
  • Release version - to lookup release notes (either literal version, or path to a file whose contents is the version)

Environment Variables:

  • GITHUB_TOKEN - a GitHub API OAuth authentication token
  • missing_ok - set to true to exit with success even if no release notes are found
  • skip_github - set to true to skip checking GitHub release notes
  • skip_local - set to true to skip checking local release notes

Usage

To use this resource type, you should configure it in the resource_types section of your pipeline.

- name: bosh-release
  type: docker-image
  source:
    repository: dpb587/bosh-release-resource

The default latest tag will refer to the current, stable version of this Docker image. For using the latest development version, you can refer to the master tag. If you need to refer to an older version of this image, you can refer to the appropriate v{version} tag.

Alternative to bosh-io-release

This resource is generally equivalent to the check/get behaviors of bosh-io-release.

If you originally used the bosh-io-release...

- name: concourse
  type: bosh-io-release
  source:
    repository: concourse/concourse

The equivalent bosh-release resource would be...

- name: concourse
  type: bosh-release
  source:
    uri: https://github.com/concourse/concourse.git

The release tarball is named {{.Name}}-{{.Version}}.tgz. If you were not using globs (e.g. release/*.tgz) you can retain the bosh-io-release behavior by configuring tarball_name. For example...

- get: stable-release
  params:
    tarball_name: release.tgz

Note that url and sha1 are not provided since tarballs are built locally.

Caveats

Subtle details you might care about...

  • This tags the commit from which the release tarball was created (commit_hash), not the commit which finalizes the release in the releases directory. This is primarily to ensure git tags match commit_hash and refer to the underlying source where changes between versions occur (as opposed to when it was finalized which may have a different set of files).
  • This uses annotated tags as opposed to lightweight tags. This enables additional metadata to be associated with when the release is published, as opposed to being restricted to when commit_hash occurred.
  • This requires that versions match semver conventions. If your release does not use a semver-compatible version, this may not work. This is primarily to encourage semver-like conventions. For releases where typical 3-tuple version numbers are not meaningful, date-based semver numbers may be a useful alternative.
  • This currently requires an externally-provided version file rather than supporting bosh's automatic major version-bumping strategy. This is primarily to encourage more explicit version management. If this becomes too burdensome, it may be worth supporting.

Development

Before committing, tests can be run locally with bin/test. After pushing, Travis CI should automatically run tests for commits and pull requests.
