Concourse Bitbucket Pull Request Resource

Tracks pull requests made to a Bitbucket repository. A status of pending, success, or failure will be set on the pull request, which must be explicitly defined in your pipeline.

Currently only basic username/password authentication offers full functionality. Private key allows scanning for pull requests because this is pure git, but verifying merge status and setting status on pull requests is done through the Bitbucket REST Api for which SSL hasn't been tested yet.

Installing

Use this resource by adding the following to the resource_types section of a pipeline config:

---
resource_types:
- name: concourse-bitbucket-pullrequest
  type: docker-image
  source:
    repository: laurentverbruggen/concourse-bitbucket-pullrequest-resource

See concourse docs for more details on adding resource_types to a pipeline config.

Source Configuration

• uri: Required. The location of the repository.

• private_key: Optional. Private key to use when pulling/pushing. Example:

  private_key: |
    -----BEGIN RSA PRIVATE KEY-----
    MIIEowIBAAKCAQEAtCS10/f7W7lkQaSgD/mVeaSOvSF9ql4hf/zfMwfVGgHWjj+W
    <Lots more text>
    DWiJL+OFeg9kawcUL6hQ8JeXPhlImG6RTUffma9+iGQyyBMCGd1l
    -----END RSA PRIVATE KEY-----
  

• username: Optional. Username for HTTP(S) auth when pulling/pushing. This is needed when only HTTP/HTTPS protocol for git is available (which does not support private key auth) and auth is required.

• password: Optional. Password for HTTP(S) auth when pulling/pushing.

• skip_ssl_verification: Optional. Skips git ssl verification by exporting GIT_SSL_NO_VERIFY=true.

• git_config: Optional. If specified as (list of pairs name and value) it will configure git global options, setting each name with each value.

  This can be useful to set options like credential.helper or similar.

  See the git-config(1) manual page for more information and documentation of existing git options.

• only_for_branch: Optional. If specified only pull requests which target those branches will be considered. It will accept a regular expression as determined by egrep.

• only_without_conflicts: Optional (default: true). If enabled only pull requests which are not in a conflicted state will be built.

• only_when_mergeable: Optional (default: false). If enabled only pull requests which are mergeable (all tasks done, required number of approvers reached, ...) will be built.

• only_when_asked: Optional (default: false). Only build pull request when explicitly asked for, using rebuild_phrase.

• rebuild_when_target_changed: Optional (default: false). Rebuild pull requests when target branch changed instead of only when source branch changed.

• rebuild_phrase: Optional (default: test this please). Regular expression as determined by egrep will match all comments in pull request overview. If a match is found the pull request will be rebuilt.

Behavior

check: Search for pull requests to build.

Check will return a version for every pull request that matches the criteria defined in source configuration.

in: Clone the repository, at the given pull request merge ref

Clones the repository to the destination, and locks it down to a given ref.

** IMPORTANT ** It is essential that you set the version to every on the get step of your job configuration. It will allow you to build all versions instead of only the latest.

Submodules are initialized and updated recursively.

Parameters

• depth: Optional. If a positive integer is given, shallow clone the repository using the --depth option. Using this flag voids your warranty. Some things will stop working unless we have the entire history.

• submodules: Optional. If none, submodules will not be fetched. If specified as a list of paths, only the given paths will be fetched. If not specified, or if all is explicitly specified, all submodules are fetched.

• disable_git_lfs: Optional. If true, will not fetch Git LFS files.

GPG signature verification

If commit_verification_keys or commit_verification_key_ids is specified in the source configuration, it will additionally verify that the resulting commit has been GPG signed by one of the specified keys. It will error if this is not the case.

out: Update the status of a pull request

Set the status message on specified pull request.

Parameters

• path: Required. The path of the repository to reference the pull request.

• status: Required. The status of success, failure or pending.

  • on_success and on_failure triggers may be useful for you when you wanted to reflect build result to the pull request (see the example below).
