Handler Plugin Template


handler-plugin-template is a template repository which wraps the Sensu Plugin SDK.
To use this project as a template, click the "Use this template" button from the main project page.
Once the repository is created from this template, you can use the Sensu Plugin Tool to
populate the templated fields with the proper values.


After successfully creating a project from this template, update the Config struct with any
configuration options for the plugin, map those values as plugin options in the variable options,
and customize the checkArgs and executeHandler functions in main.go.

When writing or updating a plugin's README from this template, review the Sensu Community
plugin README style guide for content suggestions and guidance. Remove everything
prior to # sensu-deregistration-handler from the generated README file, and add additional context about the
plugin per the style guide.

Releases with Github Actions

To release a version of your project, simply tag the target sha with a semver release without a v
prefix (ex. 1.0.0). This will trigger the GitHub action workflow to build and release
the plugin with goreleaser. Register the asset with Bonsai to share it with the community!
