Visualize your GitHub identity and access management

This guide demonstrates how to set up a monitoring solution to get insights into your GitHub Identity and Access Management (IAM) using Port's GitHub integration. Understanding your organization's IAM structure helps you audit permissions, improve security, and manage access efficiently.

Common use cases

• Understand your organization's IAM structure
• Audit GitHub organization members and their roles

Prerequisites

This guide assumes the following:

• You have a Port account and have completed the onboarding process.
• Port's GitHub app is installed in your account.

Set up data model

When installing Port's GitHub app, the Repository blueprint is created by default.
However, the GitHub User and GitHub Team blueprints are not created automatically, so we will need to create them manually.

Create the Github user blueprint

Skip to the update data source mapping section if you already have the blueprint.

1. Go to the Builder page of your portal.

2. Click on + Blueprint.

3. Click on the {...} button in the top right corner, and choose Edit JSON.

4. Add this JSON schema:

   GitHub user blueprint (Click to expand)

   {
       "identifier": "githubUser",
       "title": "Github User",
       "icon": "Microservice",
       "schema": {
           "properties": {
           "email": {
               "title": "Email",
               "type": "string"
           }
           },
           "required": []
       },
       "mirrorProperties": {},
       "calculationProperties": {},
       "aggregationProperties": {},
       "relations": {}
   }

5. Click Save to create the blueprint.

Create the Github team blueprint

Skip to the update data source mapping section if you already have the blueprint.

1. Go to the Builder page of your portal.

2. Click on + Blueprint.

3. Click on the {...} button in the top right corner, and choose Edit JSON.

4. Add this JSON schema:

   GitHub team blueprint (Click to expand)

   {
       "identifier": "githubTeam",
       "title": "GitHub Team",
       "icon": "Github",
       "schema": {
           "properties": {
           "slug": {
               "title": "Slug",
               "type": "string"
           },
           "description": {
               "title": "Description",
               "type": "string"
           },
           "link": {
               "title": "Link",
               "icon": "Link",
               "type": "string",
               "format": "url"
           },
           "permission": {
               "title": "Permission",
               "type": "string"
           },
           "notification_setting": {
               "title": "Notification Setting",
               "type": "string"
           }
           },
           "required": []
       },
       "mirrorProperties": {},
       "calculationProperties": {},
       "relations": {}
   }

5. Click Save to create the blueprint.

Update data source mapping

1. Go to the Data Sources page of your portal.

2. Select the GitHub integration.

3. Add the following YAML block into the editor to ingest data from GitHub:

   GitHub integration configuration (Click to expand)

   resources:
   - kind: repository
       selector:
       query: 'true'
       port:
       entity:
           mappings:
           identifier: .name
           title: .name
           blueprint: '"githubRepository"'
           properties:
               readme: file://README.md
               url: .html_url
               defaultBranch: .default_branch
               visibility: .visibility
   
   - kind: team
       selector:
       query: "true"
       port:
       entity:
           mappings:
           identifier: ".id | tostring"
           title: .name
           blueprint: '"githubTeam"'
           properties:
               name: .name
               slug: .slug
               description: .description
               link: .html_url
               permission: .permission
   - kind: user
       selector:
       query: "true"
       port:
       entity:
           mappings:
           identifier: .login
           title: .login
           blueprint: '"githubUser"'
           relations:
               user: .email

4. Click Save & Resync to apply the mapping.
