My company has asked me to learn Jenkins, and I'm looking for recommendations for tutorials, documentation, or video playlists. I'd like to become comfortable enough to create basic CI/CD pipelines. For someone new to DevOps, how long should I expect that to take, and what topics should I focus on first?

Start with the official Jenkins documentation and then build a small lab on your own machine. Learn how to create jobs, connect a source-code repository, use Pipeline syntax, write a Jenkinsfile, configure credentials safely, run tests, and publish artifacts. A local installation with Docker, kind, k3s, or another lightweight environment is enough for practice. With a few focused hours each week, you can usually write simple pipelines in one or two weeks; becoming comfortable with administration, agents, plugins, security, and troubleshooting takes considerably longer.
A good learning project is a pipeline for a small application: check out the code, install dependencies, run linting and tests, build an artifact or container image, and deploy it to a temporary environment. Then deliberately break a stage and learn how to inspect logs and fix it. This hands-on approach will teach you more than watching a playlist without building anything.
Jenkins is older than some newer CI/CD services, but it is still widely used, especially by organizations that need self-hosting and control over their build agents. Don’t dismiss it if your employer relies on it. At the same time, it’s worth learning the general CI/CD concepts because many platforms use similar ideas even though their configuration and management differ.
Before investing too much time, ask whether your company expects you to use an existing Jenkins setup or maintain the server itself. Writing pipelines is manageable, but securing Jenkins, managing plugins and agents, handling credentials, and keeping upgrades reliable are separate responsibilities. If you only need pipeline skills, prioritize Pipeline syntax and the Jenkinsfile first.
That makes sense. I’m still new to DevOps, so I’ll focus on transferable concepts such as triggers, stages, agents, secrets, testing, artifacts, and deployment rather than memorizing every plugin.
