Deployment pipelines (dev, staging, prod) in Jenkins - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a deployment pipeline in Jenkins?

A deployment pipeline in Jenkins is a series of automated steps that take code from development through testing and finally to production. It helps deliver software quickly and safely.

beginner

Why use separate environments like dev, staging, and prod in deployment pipelines?

Separate environments help test code safely. Dev is for initial development, staging mimics production to catch issues, and prod is the live environment users see.

intermediate

What Jenkins feature helps automate deployment steps across dev, staging, and prod?

Jenkins Pipelines use code (Jenkinsfile) to automate deployment steps, making it easy to manage and repeat deployments across environments.

How can you ensure only tested code reaches production in a Jenkins pipeline?

By adding automated tests and manual approval steps in the pipeline before deploying to production, you ensure only safe code is released.

beginner

What is the role of the 'staging' environment in a deployment pipeline?

Staging is a safe copy of production where final tests happen. It helps catch bugs before code goes live, reducing risks.

What is the first environment code usually goes to in a deployment pipeline?

A Development (dev)

B Production (prod)

C Staging

D Testing

Code is first deployed to the development environment for initial testing and changes.

Which Jenkins file defines the steps of a deployment pipeline?

A Dockerfile

B Jenkinsfile

C Pipeline.yaml

D Config.xml

Jenkinsfile is the script that defines pipeline stages and steps.

What is the main purpose of the staging environment?

A Backup storage

B Writing new code

C Final testing before production

D User training

Staging is used to test the application in an environment similar to production.

How can Jenkins pipelines help reduce errors in production?

A By deploying directly to production

B By skipping tests to save time

C By manual copying of files

D By automating tests and approvals before deployment

Automation ensures consistent testing and approvals, reducing human errors.

Which environment is usually the live system users interact with?

A Production (prod)

B Development (dev)

C Staging

D Testing

Production is the live environment where users access the application.

Explain the purpose of dev, staging, and prod environments in a Jenkins deployment pipeline.

Think about how software moves from writing code to being used by people.

Describe how Jenkins pipelines automate deployment across multiple environments.

Consider how automation replaces manual work in deployment.
