To deploy your code, you’ll need to trigger Code Manager by hitting a web endpoint. You can do this either through a webhook or a custom script. Either way, you’ll also need to set up authentication and create a custom URL.

The webhook, described on this page, is the simplest way to trigger Code Manager. Custom scripts are a good alternative if you have requirements such as existing continuous integration systems, privately hosted Git repos, or custom notifications. See Creating custom scripts for information about writing a script to trigger Code Manager.

This page assumes that you have already enabled and configured Code Manager.

Code Manager supports webhooks for GitHub, Bitbucket Server (formerly Stash), Bitbucket, and Team Foundation Server. The Code Manager webhook must only be used by the control repository. It can’t be used by any other repository (for example, other internal component module repositories).

Create a webhook

To set up the webhook to trigger Code Manager to deploy your environments:

  1. Create a custom URL that triggers Code Manager.
  2. Set up the webhook.

Create a custom URL

To trigger Code Manager, you’ll need a custom URL composed of:

  • The name of the Puppet master server (for example, code-manager.example.com)
  • The Code Manager port (for example, 8170)
  • The endpoint (/code-manager/v1/webhook/)
  • Any relevant query parameters (for example, type=github)
  • The authentication token you generated earlier (token=<TOKEN>)

Note to GitLab users: Prior to GitLab 8.5.0, GitLab had a character limit on webhooks, so the entire authentication token could not be passed. If you are using a GitLab version earlier than 8.5.0, either upgrade to the current GitLab version or turn off Code Manager webhook authentication via Hiera with the authenticate_webhook parameter.

Webhook endpoint

The webhook endpoint triggers environment deployments that are based on version control system webhooks from the control repo. Pass the authentication token with the token query parameter. To use the Github webhook with the Puppet signed cert, disable SSL verification.

Code Manager supports webhooks for GitHub, Bitbucket Server (formerly Stash), Bitbucket, and Team Foundation Server (TFS).

Query parameters

  • type: Required. Specifies which type of post body to expect. Accepts:
    • github: GitHub
    • gitlab: GitLab
    • stash: Bitbucket Server (Stash)
    • bitbucket: Bitbucket
    • tfs-git: Team Foundation Server (resource version 1.0 is supported)
  • prefix: Specifies a prefix for converting branch names to environments.
  • token: Specifies the entire PE authorization token.

So, a URL for a GitHub webhook might look like this:

https://code-manager.example.com:8170/code-manager/v1/webhook?type=github&token=<TOKEN>

The URL for a Stash webhook might look something like this:

https://code-manager.example.com:8170/code-manager/v1/webhook?type=stash&prefix=dev&token=<TOKEN>

With the complete token attached, a GitHub URL looks something like this:

https://code-manager.example.com:8170/code-manager/v1/webhook?type=github&token=eyJhbGciOiJSUzUxMiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJkZXBsb3kiLCJpYXQiOjE0NDY2NjQ1OTAsImV4cCI6MTQ3ODI4Njk5MCwic3ViIjp7ImlkIjoiZWNmOTJlYzYtMjg1Zi00NzExLWI0MDktMzFmMGYzMGIzOGUwIiwibG9naW4iOiJkZXBsb3kifX0.OdEIA-HGRC0r2J87Pj2sDsyz-EMK-7sZalBTswy2e3uSv1Z6ulXaIQQd69PQnSSBExQotExDgXZInyQa_le2gwTo4smjUaBd6_lnPYr6GJ4hjB4-fT8dNnVuvZaE5WPkKt-sNJKJwE9LiEd4W42aCYfse1KNgPuXR5m77SRsUy86ymthVPKHqqexEyuS7LGeQJvyQE1qEejSdbiLg6znlJXhglWic6ZEpHcYBrFFE4aNwuOYXM4yIL803yIMviBwXRtt9HxbtUBZ8D4ag14ELMefQTlqrKvepKXd29oJG06FwkKcWV9PWiQ0Q-NrE17oxrrNkU0ZxioUgDeqGycwvNIaMazztM9NyD-dWmZc4dKJsqm0su0CRkMSWcYPPaeIcsYFI7XSaeC65N4RLIKhUfwIxxE-uODEhcl3mTr9rwZGnVMu3WrY7t6wlbDM9FomPejGM2aJoZ05PinAIYvX3oH5QJ9fam0pVLb-mI3bvkKm2wKAgpc4Dh1ut9sqLWkG8-AwMA4r_oEvLwFzf8clzk34zNyPG7BvlnPle99HjQues690L-fknSdFiXyRZeRThvZop0SWJzvUSR49etmk-OxnMbQE4tCBWZr_khEG5jUDzeKt3PIiXdxmUaaEPHzo6Vl9XIY5

Set up the webhook

Enter the URL you created above into your Git server’s webhook form as the payload URL. Exactly how you do this varies, depending on where your Git repos are hosted. For example, in your Github repo, click on Settings > Webhooks & services to enter the URL.

The content type for webhooks is JSON.

Testing and troubleshooting

To test and troubleshoot your webhook, review the webhook runs logged by your repository host. Each of the major repository hosting services (such as GitHub or Bitbucket) provides a way to review your webhook runs, so check their documentation for instructions.

For other issues, check the Code Manager troubleshooting for some common problems and troubleshooting tips.

Next steps

At this point, your Code Manager setup is complete. Code Manager is ready to deploy your new code into your environments. Commit new code and push it to your control repo. The webhook triggers Code Manager, and your code is deployed.
