GitHub Action - Octopus Build Information

This GitHub Action (written in JavaScript) generates a JSON build information file for Octopus Deploy. Optionally, it can also query the Octopus Deploy API to detect the previously-deployed release and push the generated build information to the Octopus Deploy server.

Usage

Inputs

All inputs are optional (or have reasonable default values). However, without inputs, the action does nothing. Enable features by providing the appropriate input. Also, an octopus_api_key and octopus_server URL are required when either octopus_project or push_package_ids is set, and push_version is required when push_package_ids is set.

• github_token: GitHub personal access token. Used get commit history from the repository. Defaults to the token provided by the workflow run.
• octopus_api_key: Authentication key for the Octopus Deploy API. Can also be set via the environment variable OCTOPUS_CLI_API_KEY.
• octopus_server: URL of the Octopus Deploy server. Can also be set via the environment variable OCTOPUS_CLI_SERVER.
• octopus_query_string: Query String to send to the Octopus Deploy Server. E.g., take=50. REST API Documentation via Swagger.
• octopus_environment: Use the previous release deployed to this environment to generate commit history. Defaults to "Production" or, if there is no such environment, to the last environment in the space. Can also be set via the environment variable OCTOPUS_ENVIRONMENT.
• octopus_project: Name of the Octopus Deploy project to query for the previous deployment. Omit to skip querying Octopus Deploy and generating commit history. Can also be set via the environment variable OCTOPUS_PROJECT.
• octopus_space: Name of the Octopus Deploy space that contains octopus_project. Defaults to the default space. Can also be set via the environment variable OCTOPUS_SPACE.
• output_path: The path to an output directory. When present, this action writes these files:
  • ${output_path}/buildInformation.json: the build information JSON.
  • ${output_path}/buildInformationMapped-${package_id}.json: the full, mapped build information returned by the Octopus Deploy server after pushing build information for ${package_id}.
• push_overwrite_mode: Action to take when pushing build information that already exists: FailIfExists, IgnoreIfExists, or OverwriteExisting. Defaults to FailIfExists.
• push_package_ids: Whitespace-separated list of package IDs. Omit to skip pushing the discovered build information to the Octopus Deploy server.
• push_version: Version of the package(s) listed in push_package_ids. When the workflow run was triggered by a tag, you may pass the github.ref, and the prefix refs/tags/${version_tag_prefix} will be stripped.
• version_tag_prefix: Prefix for release version tags, used to probe for a GitHub release tag when the previous Octopus Deploy deployment metadata contains a version number but not a commit SHA. Defaults to v.

The inputs octopus_environment, octopus_project, and octopus_space accept names ("My Project"), slugs ("my-project"), and hyphenated Octopus IDs ("Projects-1").

Outputs

• output_file: The full path to ${output_path}/buildInformation.json.
• previous_release_sha: The commit SHA of the previous release, if one was detected by querying Octopus Deploy for the previous deployment.
