CI/CD pipeline mental model in Jenkins - 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 codebase 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 software updates to users quickly and safely.

beginner

In Jenkins, what is a pipeline?

A Jenkins pipeline is a set of automated steps defined in code that build, test, and deliver software. It helps teams automate their CI/CD process.

beginner

Why is automation important in CI/CD pipelines?

Automation reduces manual work, speeds up software delivery, and lowers the chance of human errors. It helps teams deliver better software faster.

beginner

Name three common stages in a CI/CD pipeline.

Common stages include: 1) Build - compiling code, 2) Test - running automated tests, 3) Deploy - releasing the software to users or servers.

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

A Run user acceptance tests

B Deploy to production

C Build the code

D Monitor application performance

The first step is usually to build the code to make sure it compiles and is ready for testing.

Which tool is commonly used to automate CI/CD pipelines?

A Photoshop

B Jenkins

C Excel

D Slack

Jenkins is a popular automation server used to create and run CI/CD pipelines.

What does Continuous Deployment mean?

A Automatically releasing every change to users

B Manually testing software before release

C Writing code without testing

D Deploying software once a year

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

Why do we run automated tests in a CI/CD pipeline?

A To catch bugs early and ensure quality

B To slow down the pipeline

C To confuse developers

D To avoid writing code

Automated tests help find problems early so they can be fixed before release.

Which stage comes after testing in a CI/CD pipeline?

A Designing

B Coding

C Planning

D Deployment

After tests pass, the software is deployed to users or servers.

Explain the mental model of a CI/CD pipeline and why it is useful.

Think about how software moves from code to users automatically.

Describe how Jenkins helps implement a CI/CD pipeline.

Imagine Jenkins as a helpful robot that runs your software steps.
