Hybrid CI/CD approaches in Jenkins - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a Hybrid CI/CD approach?

A Hybrid CI/CD approach combines both centralized and decentralized pipelines to leverage the strengths of each, allowing flexibility and scalability in software delivery.

Why use a Hybrid CI/CD approach in Jenkins?

It allows teams to use shared centralized pipelines for common tasks while enabling individual teams to customize their own pipelines, improving efficiency and collaboration.

beginner

Name two benefits of Hybrid CI/CD approaches.

1. Flexibility to adapt pipelines per team needs. 2. Better resource management by sharing common pipeline components.

intermediate

How can Jenkinsfiles be used in Hybrid CI/CD?

Jenkinsfiles can be stored in each project repository for team-specific pipelines, while shared libraries provide reusable pipeline code for centralized tasks.

advanced

What is a common challenge when implementing Hybrid CI/CD?

Maintaining consistency and avoiding duplication between centralized and decentralized pipelines can be challenging without clear governance and communication.

What does a Hybrid CI/CD approach combine?

A Centralized and decentralized pipelines

B Manual and automated testing only

C Only cloud-based pipelines

D Only on-premise pipelines

A Hybrid CI/CD approach combines centralized and decentralized pipelines to balance control and flexibility.

In Jenkins, where are team-specific pipeline definitions usually stored in a Hybrid CI/CD setup?

A In each project repository as Jenkinsfiles

B Only in the Jenkins master server

C In external cloud storage unrelated to the project

D In a shared database

Team-specific Jenkinsfiles are stored in each project repository to allow customization.

What is a key benefit of using shared libraries in Jenkins Hybrid CI/CD?

A Replacing all Jenkinsfiles

B Running pipelines only manually

C Eliminating the need for pipelines

D Reusing common pipeline code across projects

Shared libraries help reuse common pipeline code, reducing duplication.

Which is a common challenge in Hybrid CI/CD approaches?

A Only using one programming language

B Lack of any automation

C Maintaining consistency between pipelines

D No need for version control

Maintaining consistency and avoiding duplication is a common challenge.

Why might teams prefer Hybrid CI/CD over fully centralized pipelines?

A To use only manual deployments

B To allow customization and faster iteration

C To remove automation completely

D To avoid using Jenkins

Hybrid CI/CD allows teams to customize pipelines and iterate faster.

Explain how Jenkins supports Hybrid CI/CD approaches with Jenkinsfiles and shared libraries.

Think about where pipeline code lives and how teams share common parts.

Describe the main benefits and challenges of adopting a Hybrid CI/CD approach.

Consider what makes hybrid useful and what problems it might cause.
