Apply Dependency Update in Azure Pipelines

B

DependaBot is a useful tool to regularly check for dependency updates. By helping to keep your project up to date, DependaBot can reduce technical debt and immediately apply security vulnerabilities when patches are released. How does DependaBot work?

1. DependaBot regularly checks dependencies for updates

2. If an update is found, DependaBot creates a new branch with this upgrade and Pull Request for approval

3. You review the new Pull Request, ensure the tests passed, review the code, and decide if you can merge the change

When Dependabot detects a dependency in App1 that requires an update, the first step to apply the update is to create a branch. Therefore, the correct answer is option C, "Create a branch."

Here's why:

Azure Pipelines is used to manage build pipelines. When a change is made to the source code in GitHub, the pipeline will be triggered, and the pipeline will build and deploy the app. The pipeline can be configured to automatically deploy changes to the production environment or to require approval before deploying.

Dependabot is a GitHub feature that automatically detects and updates dependencies in your code. When Dependabot detects a dependency in App1 that requires an update, it creates a pull request (option A). However, creating a pull request is not the first step to apply the update.

Before making any changes, it is always a good practice to create a branch (option C). The branch is a copy of the code that can be modified without affecting the original code. Once the branch is created, Dependabot will create a pull request to update the dependency. The pull request will contain the changes to the code required to update the dependency.

After the pull request is created, it needs to be approved (option B) by a reviewer. The reviewer will review the changes and either approve or reject the pull request. If the pull request is approved, the changes will be merged into the main branch, and the pipeline will be triggered to build and deploy the app.

Finally, when the changes are merged into the main branch, a commit (option D) will be made to the repository, and the updated dependency will be included in the next build and deployment.
