Task 03 - Cleanup GitHub artifacts

Introduction

As part of this training, you created GitHub secrets, variables, workflows, issues and pull requests that you may not want to retain in your organization or repository going forward. In particular, any secrets or variables could post a security concern if they were able to be misused. You can remove all of these artifacts to restore your organization and repository to a cleaner pre-lab state.

Description

In this task, you will remove GitHub secrets, variables, workflows, issues, pull requests, and other artifacts created during the lab exercises. This ensures your GitHub repository and organization are clean.

NOTE As you executed Copilot instructions during this lab, you may have different results for the names of credentials, variables and other artifacts. You will have to apply your actual names to the instructions below.

Success Criteria

You have removed all GitHub secrets
You have removed all GitHub variables
You have cleaned up all workflow runs (optional)
You have closed all lab-related issues
You have closed or merged all pull requests

Key Tasks

01: Remove GitHub Secrets

Remove all secrets that were created for the lab.

Expand this section for detailed steps

NOTE The secrets to remove are your service principal credentials such as:

AZURE_CREDENTIALS

From the command line

From Terminal in Visual Studio Code, run the following commands:

 # Using GitHub CLI (recommended)
 gh secret delete AZURE_CREDENTIALS

 # If you have multiple secrets, list them first
 gh secret list

 # Delete each secret
 gh secret delete <secret-name>

From GitHub UI

Navigate to your repository in your GitHub organization.
Go to Settings → Secrets and variables → Actions.
Under Secrets, click on each secret.
Click Delete and confirm.

02: Remove GitHub Variables

Remove all variables that were created for the lab.

AZURE_CONTAINER_REGISTRY_NAME

AZURE_APP_SERVICE_NAME

AZURE_RESOURCE_GROUP (if created)

AZURE_LOG_WORKSPACE_ID or LOG_WORKSPACE_ID

From the command line

From Terminal in Visual Studio Code, run the following commands:

 # Using GitHub CLI
 gh variable list

 # Delete each variable
 gh variable delete AZURE_CONTAINER_REGISTRY_NAME
 gh variable delete AZURE_APP_SERVICE_NAME
 gh variable delete AZURE_RESOURCE_GROUP
 gh variable delete AZURE_LOG_WORKSPACE_ID
 gh variable delete LOG_WORKSPACE_ID

From GitHub UI

Navigate to your repository.
Go to Settings → Secrets and variables → Actions.
Under Variables, click on each variable.
Click Delete and confirm.

03: Clean Up GitHub Actions Workflows

Delete workflow files or disable them and keep them for reference.

Delete workflow files (recommended for cleanup)

From the Terminal window in Visual Studio Code, navigate to the root of your repository.

Run the following commands to delete workflow files:

 # Delete workflow files
 git rm .github/workflows/*.yml
 git commit -m "Remove lab workflow files"
 git push

NOTE: The .github/workflows/jekyll-gh-pages.yml file is for GitHub Pages and should be kept if you’re using GitHub Pages.

Keep workflow files but disable them

Open the YAML file and comment out the triggers:

 # Comment out the triggers in your workflow file
 # on:
 #   push:
 #     branches: [ main ]
 #   pull_request:
 #     branches: [ main ]

04: Clean Up Workflow Runs (Optional)

Delete individual workflow runs from the command line or from GitHub UI.

NOTE: Workflow runs are automatically deleted after 90 days. Manual deletion is optional.

From the command line

List workflow runs:
```
 gh run list
```
Delete a specific workflow run:
```
 gh run delete <run-id>
```

From GitHub UI

Navigate to your repository.
Go to Actions tab.
Click on a workflow run.
Click the … menu → Delete workflow run.

Expand this section for detailed steps

The issues to close or delete include:

Infrastructure provisioning issue (Exercise 2)
.NET upgrade issue (Exercise 5)
Chat feature issue (Exercise 5)
Any vulnerability tracking issues (Exercise 4)

From the command line

List all open issues:
```
 gh issue list --state open
```
Close an issue:
```
 gh issue close <issue-number>
```
Delete an issue (requires repository admin permissions):
```
 gh issue delete <issue-number>
```

From GitHub UI

Navigate to your repository.
Go to Issues tab.
Open each issue.
Click Close issue or Delete (if you have permissions).

06: Close Pull Requests

Close any open pull requests created during the lab from the command line or from GitHub UI.

Expand this section for detailed steps

Navigate to your repository.
Go to Pull requests tab.
Open each PR.
Click Close pull request or Delete (if you have permissions).

07: Verification

Verify that all GitHub artifacts have been removed.

Expand this section for detailed steps

Run the following verification commands:

 # Verify no secrets remain
 gh secret list

 # Verify no variables remain
 gh variable list

 # Verify no open issues remain
 gh issue list --state open

 # Verify no open PRs remain
 gh pr list --state open

 # List workflow files
 ls .github/workflows/
