DevOps Complete Course - Why Do We Need Branches on Git

The video tutorial discusses the importance of branches in code management, explaining how the default master branch is used and the benefits of creating additional branches. It outlines a typical DevOps workflow, highlighting the role of source code management, build tools, and deployment processes. The tutorial emphasizes the challenges of using only the master branch for deployments, such as potential bugs and system downtime. It advocates for using separate branches to ensure only working code is deployed, thus maintaining system stability and allowing for continuous updates. The video concludes with a teaser for the next tutorial on branching strategies.

What is the default branch created when a new repository is initialized?

• Release

• Master

• Feature

• Development

In a typical DevOps workflow, what is the purpose of creating artifacts?

• To manage user access

• To store raw code

• To delete unnecessary files

• To compile code into executable files

What is the role of deployment tools in the DevOps workflow?

• To write new code

• To test code quality

• To deploy artifacts to the server

• To manage user permissions

Why might relying solely on the master branch for deployments be problematic?

• It increases the number of branches

• It can lead to deploying unstable code

• It complicates the code review process

• It requires more storage space

What happens to the application when non-working code is pushed to the master branch?

• The application becomes more secure

• The application is automatically updated

• The application may break

• The application runs faster

How do branches help in maintaining system stability during deployments?

• By reducing the number of developers

• By allowing only stable code to be deployed

• By increasing the number of commits

• By simplifying the codebase

What is a key advantage of using branches in a DevOps workflow?

• Simplified user interface

• Easier bug tracking

• Ensuring only tested code is deployed

• Faster code compilation
