Scaffold BitBucket Repositories Using Cookiecutter

This example demonstrates how to quickly scaffold BitBucket repositories using a Cookiecutter Template via Port Actions.

In addition, as cookiecutter is an open-source project you can make your own project template, learn more about it here.

Example - scaffolding golang template​

Follow these steps to get started with the Golang template:

  1. Create the following as Jenkins Credentials:

    1. BITBUCKET_USERNAME - a user with access to the BitBucket Workspace and Project.
    2. BITBUCKET_APP_PASSWORD - an App Password with the Repositories:Read and Repositories:Write permissions permissions.
    3. PORT_CLIENT_ID - Port Client ID learn more.
    4. PORT_CLIENT_SECRET - Port Client Secret learn more.

  2. Create a Port blueprint with the following properties:

note

Keep in mind this can be any blueprint you would like and this is just an example.

{
  "identifier": "microservice",
  "title": "Microservice",
  "icon": "Microservice",
  "schema": {
    "properties": {
      "description": {
        "title": "Description",
        "type": "string"
      },
      "url": {
        "title": "URL",
        "format": "url",
        "type": "string"
      }
    },
    "required": []
  },
  "mirrorProperties": {},
  "calculationProperties": {},
  "relations": {}
}
  1. Create Port action using the following JSON definition:
note

Make sure to replace the placeholders for JENKINS_URL and JOB_TOKEN.

        },

      }
    }
  }
}

  1. Create a Jenkins Pipeline with the following configuration:

    1. Enable webhook trigger for a pipeline

    2. Define variables for a pipeline: Define the REPO_NAME, BITBUCKET_WORKSPACE_NAME, BITBUCKET_PROJECT_KEY and RUN_ID variables.

      Define Vars

    3. Token Setup: Define the token to match JOB_TOKEN as configured in your Port Action.

  2. Add the following content to the new pipeline:
