CI/CD pipeline basics in Django - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does CI stand for in DevOps?

CI stands for Continuous Integration. It means automatically combining code changes from many developers into a shared main branch frequently.

beginner

What is the main goal of a CD pipeline?

CD stands for Continuous Delivery or Continuous Deployment. Its goal is to automatically prepare and release code changes to production or staging environments safely and quickly.

Name three common stages in a CI/CD pipeline.

Common stages include: 1) Build - compiling and preparing code, 2) Test - running automated tests, 3) Deploy - releasing code to an environment.

Why is automated testing important in CI/CD?

Automated tests quickly check if new code breaks anything. This helps catch errors early and keeps the software reliable.

How does a CI/CD pipeline help a Django project?

It automates building, testing, and deploying Django code. This saves time, reduces mistakes, and delivers updates faster to users.

What is the first step in a typical CI/CD pipeline?

A Build the code

B Deploy to production

C Run automated tests

D Write documentation

The pipeline usually starts by building the code to prepare it for testing and deployment.

Which of these is NOT a benefit of CI/CD?

A Faster delivery of features

B Manual error-prone deployments

C Early detection of bugs

D Consistent software releases

CI/CD reduces manual deployments, which are error-prone. So manual error-prone deployments are not a benefit.

In a Django project, what tool might you use to run tests in a CI pipeline?

A npm install

B docker build

C pytest or Django's test runner

D git commit

pytest or Django's built-in test runner are used to run tests in Django projects.

What does Continuous Deployment mean?

A Automatically releasing every change to production

B Manually deploying code after testing

C Only building code without testing

D Writing code continuously

Continuous Deployment means every change that passes tests is automatically released to production.

Which stage ensures code changes do not break existing features?

A Committing

B Building

C Deploying

D Testing

Testing runs automated checks to make sure new code does not break existing features.
