Concourse Github Issue Resource

A concourse-ci resource for interacting with Github Issues.

This resource's container image is currently hosted at matthewschuchard/concourse-github-issue-resource for usage within Concourse.

This repository and project is based on the work performed for MITODL, and now serves as an upstream for the project hosted within that organization. Accordingly it maintains the BSD-3 license with copyright notice.

Behavior

source: designates the Github repository, issue number, and personal access token

parameters

• pat: required/optional The personal access token for authentication and authorization. If anonymous read and write for Issues is permitted, then this is optional for the check and out steps. Otherwise it is required for private repos, or any other situation where anonymous read and write for Issues is not authorized.

• owner: required The owner of the target repository expressed as either a user or organization.

• repo: required The Github repository with the issue tracker in which to read and/or write issues.

• skip_check: optional A boolean that signifies whether to skip the check step or not. This is primarily useful for situations where it is known that a specified issue does not exist, and instead must be created during out.

• number: optional/required The issue number to read during the check step for triggering Concourse pipelines based on the issue state, or for updating during the out step. If this is omitted then instead a list operation with filters (i.e. "search") occurs to determine the issue during the check step, and a create operation during the out step. Therefore this is implicitly required if an issue update is desired as a new issue creation attempt will occur during out otherwise.

The following parameters are for filtering from a list of issues to one issue (i.e. "search") during the check step, and therefore their values are ignored when an input value is specified for the number parameter.

• state: optional The current state of the searched issue. This can be either open, closed, or all.

• milestone: optional The numeric ID of the milestone associated with the searched issue.

• assignee: optional The user name of the assignee for the searched issue.

• labels: optional (value currently ignored) The list of labels for the searched issue.

version: designates the Github issue state

parameters

• version: optional The state of the issue specified in the source expressed as the enum closed or open (note the states' serialization is implemented by Octocrab to be lowercase strings). This is an output only and is ignored as an input parameter.

version:
  state: <issue state>

check: returns size two list for closed Github issues and size one list for open Github issues

The check step determines the state of the specified Github issue. If the state is closed then the returned list of versions is size two. If the state is open then the returned list of versions is size one. This is specifically to trigger pipelines based on the issue state (closed triggers and open does not trigger) because it simulates a delta of versions for closed and not open. The actual returns are the following (note the states' serialization is implemented by Octocrab to be lowercase strings):

closed:

[{"state":"open"},{"state":"closed"}]

open:

[{"state":"open"}]

in: currently unused

This ignores any inputs and quickly dummies outputs, and therefore is primarily useful for executing an efficient check step with minimal overhead.

out: creates a Github issue

The out step updates or creates a Github issue according to the input parameters below. The number of the created Github issue is written to a file at /opt/resource/issue_number.txt so that it can be re-used later in the build (especially for a subsequent check step to trigger Concourse steps based on the status of the Github issue created during this step).

Recall that the parameter which determines whether a create or update operation occurs during this step is source.number.

The metadata output from this step contains the number, url, title, state, labels, assignees, milestone, created time, and last updated time for the issue.

• title: optional/required The title of the written Github issue (required for new issue).

• body: optional The body of the written Github issue.

• labels: optional (value currently ignored for update) The list of labels for the written Github issue.

• assignees: optional (value currently ignored for update) The list of assignees for the written Github issue.

• milestone: optional The milestone numeric ID to associate with the written Github issue.

• state: optional The desired state of the updated issue. This can be either open or closed.

Metadata

Below is the general structure of the generated Concourse metadata. Note that the labels and assignees keys will not exist if their value is empty, and the milestone key will not exist if its value is null.

{
  "number": "issue number",
  "url": "issue url",
  "title": "issue title",
  "state": "open|closed",
  "labels": ["issue labels (see below doc link)"],
  "assignees": ["issue assignees (see below doc link)"],
  "milestone": "issue milestone (see below doc link)",
  "created": "issue creation time",
  "updated": "issue updated time"
}
