⚙️ Jenkins Flashcards
⚙️ What is Jenkins?
Jenkins is an open-source automation server used for continuous integration (CI) and continuous delivery (CD).
🤖 What is a Jenkins Pipeline?
A Pipeline is a suite of plugins that enables CI/CD workflows, defined via Jenkinsfile or UI.
📜 What is a Jenkinsfile?
A Jenkinsfile is a text file that defines the pipeline as code using Groovy-based DSL.
🔌 What are Jenkins Plugins?
Plugins extend Jenkins’ functionality for SCM, build tools, containers, cloud services, and notifications.
📦 What are Jobs in Jenkins?
Jobs (or projects) define tasks that Jenkins executes, like building, testing, or deploying software.
🔗 What is a Build Trigger?
Build Triggers are events that start a job automatically, such as code commits, cron schedules, or webhook calls.
🌐 What is the Jenkins Master-Slave Architecture?
The master coordinates tasks, while slave (agent) nodes execute build steps in distributed environments.
🛠️ What are Declarative Pipelines?
Declarative Pipelines provide a simpler syntax to define stages and steps compared to scripted pipelines.
🔒 How does Jenkins handle security?
Jenkins supports role-based access, credential storage, and integrates with SSO solutions like LDAP and SAML.
📡 How does Jenkins integrate with Git?
Jenkins can pull code from Git repos, build and test it automatically, and trigger pipelines on commits via webhooks.
🚀 What is Blue Ocean in Jenkins?
Blue Ocean is a modern UI for Jenkins that simplifies pipeline visualization and monitoring.
💡 What are Shared Libraries?
Shared Libraries allow you to reuse pipeline code across multiple projects by storing common Groovy scripts.
