Learn Jenkins From The Scratch and prepare for Job Interview

Learn how to create a Jenkins job, name it, and choose between freestyle and pipeline, then explore configuration options, workspace basics, and how to run builds.

Learn to configure Jenkins jobs with thorough descriptions, build discard strategies, and artifact retention. Explore parameterized builds, GitHub project, and concurrency controls for reliable, traceable ci.

Explore configuring source code management in Jenkins jobs with Git, including selecting repositories and branches, adding SSH key credentials, managing labels, and tuning advanced checkout, clone, and build trigger options.

Trigger builds remotely via a predefined URL with a token for scripts. Configure downstream and periodic triggers, GitHub hook triggers, and build-blocking rules to manage jobs.

Set up a clean Jenkins build environment by deleting the workspace and using secret credentials for shell tasks. Monitor build logs with timestamps and explore Gradle build scans for troubleshooting.

Configure a Jenkins job build by executing Unix shell or Windows batch commands and Maven targets, manage exit codes, and set build status from GitHub commits for deployments.

Configure Jenkins to aggregate downstream test results and archive artifacts after builds. Publish unit test results, enable GitHub commit status, and notify teams via email or Slack for build outcomes.

Learn how to organize Jenkins jobs using views, create list views, and select which jobs appear, with custom filters, columns, and statuses for staging, production, and development.

Explore the system information in manage Jenkins to review system properties, version details, the executable war path, Java home, Jenkins home, and plugins memory usage.

Explore Jenkins system logs, view records, and create a log recorder to capture environment variables, log messages, and log levels for troubleshooting.

Configure the global tool settings, including JDK, Git, Gradle, and Maven versions, with automatic installation and default settings. Apply and save to enable tools across all projects.

Configure the Jenkins system by setting home directory, system messages, executables, labels, and queue behavior; manage global properties, environment variables, tools, and SMTP notifications.

Explore managing Jenkins plugins, including installation, uninstallation, and dependency handling, with advanced proxy settings and site updates. Learn to configure Slack notification plugins, install without restart, and test post-build actions.

Create and manage Jenkins users by adding new accounts and configuring details such as full name, description, email, API token, and time zone.

Configure global security in Jenkins by selecting an authentication method (Jenkins user database, LDAP, servlet, or UNIX) and applying matrix-based or project-based authorization to control access.

Learn to manage Jenkins credentials by creating global and domain scopes, organize for DevOps and QA teams, and add username/password, private keys, secret texts, and certificates for GitHub and nodes.

Learn how to set up Jenkins master and slave nodes, configure executors, labels, launch methods, credentials, and connectivity to run jobs on designated nodes.

Build an AWS VPC with public and private subnets, internet gateway, and add gateway, then install Jenkins, configure its URL to the IP, and integrate with GitHub to trigger jobs.

Create a vpc named cyclops dash bbc with IPv4 10.0.0.0/16 and no IPv6. Create two subnets inside it: a public subnet 10.0.0.0/24 and a private subnet 10.1.2.0/24.

Learn how to set up internet gateway and nat gateway in a vpc, create public and private subnets, and configure route tables and elastic ips for internet access.

Install and configure a VB VPN server on an Ubuntu 18.x instance, including security group setup and MongoDB backend. Create organizations, servers, and user configurations for VPN access.

Set up the vpn, create an organization and users, attach a server, and configure security groups to enable private subnet access via vpn keys.

Learn how to install and configure Jenkins on a private cloud instance, including setting up Java 8, VPN access, secured security groups, and initial Jenkins setup with port 8080.

Set up Jenkins behind nginx as a reverse proxy to port 8080, configure a private Route 53 hosted zone, and map a private domain to Jenkins via vpn.

Explore integrating Jenkins with GitHub to trigger builds on push and pull request events, configure GitHub webhooks, and run a freestyle Jenkins project from a GitHub repository.

Learn how to configure Jenkins to automatically build on GitHub events (push and PRs) using webhooks and the GitHub Pull Request Builder plugin, including troubleshooting branch names and deployment flow.

Explore Jenkins fundamentals for interview prep, covering what Jenkins is, its features, groovy scripting, installation steps, pipelines, and CI/CD concepts.

Discover how to create a freestyle Jenkins job, configure it, meet requirements like a Git repository and a Maven build, explore essential plugins, backups, and moving Jenkins across servers.

Master Jenkins interview essentials, including what a Jenkinsfile defines and its role in pipelines. Compare Jenkins with Bamboo and Hudson, and learn integration with git, selenium, Kubernetes, and job DSL.

Explore practical Jenkins interview topics from building pipelines to multi-branch deployments, parameterization, agent configuration, and authentication, including plugin deployment, backup, and triggers.
