Continue in lesson order.
Create the First Jenkins Job and Read Build Evidence
Create a first Jenkins job, compare Freestyle and Pipeline execution, and learn to interpret queue, workspace, logs, tests and artifacts.
Pipeline Types, Declarative and Scripted Jenkinsfiles
Learn which Jenkins job and Pipeline model to use, how Declarative and Scripted syntax differ, and how agents, stages, parameters, conditions, parallel, matrix and libraries fit together.
Secure the Jenkins Controller, Authentication and Authorization
Secure Jenkins authentication, authorization, HTTPS, folders, agents and recovery.
Configure Linux, Windows, SSH and WebSocket Agents
Build an isolated Jenkins controller and connect Linux and Windows agents with labels, least privilege, SSH or WebSocket, and practical diagnostics.
Connect GitHub, Webhooks and Multibranch Pipelines
Connect Jenkins to GitHub with a least-privilege GitHub App, signed webhooks, Multibranch Pipeline discovery, pull-request controls and diagnostics.
Manage Jenkins Credentials Without Leaking Secrets
Store and use Jenkins credentials without hardcoding them, select the correct credential type and scope, prevent log and workspace exposure, and design safe pull-request boundaries.
Control Workspaces, Stash, Artifacts and Build Retention
Understand Jenkins workspaces, prevent cross-build contamination, clean safely, move data between agents and diagnose disk and permission failures.
Manage Plugins, Dependencies and Safe Upgrades
Manage Jenkins plugins as controlled code dependencies: inventory, evaluate, install, update, remove, back up, test and recover safely.
Configure Jenkins with JCasC and Reproducible Bootstrap
Configure Jenkins reproducibly with JCasC, pinned plugins and external secrets.
Back Up, Restore and Rehearse Jenkins Disaster Recovery
Build and test a Jenkins controller backup, restore and disaster-recovery procedure.
Monitor Jenkins, Audit Changes and Plan Build Capacity
Monitor Jenkins queues, executors, agents, controller health, audit events and capacity.
Build, Test and Package Node.js with Jenkins
Build a reproducible Node.js Jenkins Pipeline with pinned runtimes, npm ci, lockfiles, tests, coverage, caching boundaries and deployable artifacts.
Build, Test and Package Java with Maven and Jenkins
Build, test and package Java with Maven in a reproducible Jenkins Pipeline.
Design Preflight, Post Actions, Timeouts and Recovery
Design reusable preflight and post-build scripts with Declarative Pipeline post conditions, timeouts, retries, cleanup, reports and failure-safe notifications.
Create Tested and Versioned Jenkins Shared Libraries
Create, test, secure and version Jenkins Shared Libraries for reusable Pipelines.
Run Kubernetes Agents and Safe Terraform Pipelines
Run Terraform on ephemeral Kubernetes agents, preserve the reviewed plan, add policy scans and approvals, route monorepo changes, and avoid privileged-agent and plan/apply drift.
Deploy Immutable Releases Through SSH
Deploy a tested artifact from Jenkins over SSH using scoped keys, verified host identities, atomic release links, health checks and rollback.
Deploy Git Tags and Roll Back to a Previous Release
Build and deploy verified Git tags, map each tag to an immutable artifact, safely select a previous release, redeploy without rebuilding, and roll back after failed health checks.
Complete Jenkins CI/CD Capstone from Commit to Recovery
Assemble GitHub discovery, isolated agents, tests, security checks, immutable artifacts, approval, SSH deployment, health checks, evidence and rollback.
