Jenkins is an open source automation server which enables you to reliably build, test, and deploy your software. It is one of the most sought over skills for a DevOps Engineer to have. There are many other 'newer' CI/CD solutions like CircleCI and Github Actions but Jenkins still has the largest footprint in the CI/CD space. Knowing how to setup and manage a Jenkins Infrastructure as well as how to setup and troubleshoot Freestyle builds and Groovy Pipelines is something you that will help you grow your Career as an Engineer.

In this video we go over what is Jenkins, and how we can install Jenkins and create CI/CD Pipelines.

No one can be told what Jenkins really is, you have to see it for yourself

I had answered couple of questions under this video and I had posted a question of my own. But I can't find them. Is it being removed? Am I violating any rules of this channel? Please let me know so that I can correct that.

Thank you.

Hi sir, why at 54:04 whenever i build the project, it always have error and when i check the logout console, i see message 'Still waiting to schedule task
‘Jenkins’ doesn’t have label ‘docker-agent-py’' although the label of agent is correct. Help me with this, sir. Thank you so much!

Watched a ton of "Jenkins" videos this weekend and this one was the absolute best ! Presentation + content were both awesome.

What do you think of Jenkins? It's not the 'latest' CI/CD tool out there but in the industry it's still seen as a tried, tested and true solution. Many companies are still dependent on their Jenkins infrastructure, and will be for many more years to come.

For anyone using this on Arm architecture like a Raspberry Pi for example: change the Dockerfile first line from:
FROM jenkins/jenkins:2.332.3-jdk11

to:
FROM jenkins4eval/jenkins

Otherwise it won't build!

43:39 whats the correct jdk version for ARM ? im getting an error: Could not pull image: no matching manifest for linux/arm64/v8 in the manifest list entries**

Hi, very cool so far thx!! However, at about 31:40 I get stock when it is about running python. I'm running jenkins-docker impage (jenkins/jenkins:lts-jdk11). However, I'm unable to recognize "python", "python3", ... (whatever) in the container shell. I added the python plugin (as one existed), but didn't help. How did you manage to have python running on your container?
Cheers

38:49 did troubleshooting for about 4-5 hrs couldn't solve issue it's just not working man.

This should be the top video when looking for a beginners Jenkins guide!

Hi Brad, great course on Jenkins. I like how you went thorough the steps of explaining Jenkins concepts to setup of Jenkins and agents with Docker. One of the best videos on the Jenkins on YouTube. Thanks👍

[duonginhxuan]

I used docker cloud as jenkins agent node (docker-agent-alpine). How to build image on it (docker-agent-alpine) and push image to docker hub ?

[justinburgess]

Very helpful. Thank you!

Btw, the name is 'perMaNent agent', not 'perNaMent agent.' A small, but important detail.

I thought it might be a typo at first, but the instructor continues to use the incorrect spelling and pronunciation of this name throughout the video.

Hi, it is a great tutorial thank you so much! I tried to install the Jenkins but when i give the password the next page is 404 not found. What should the problem? Thank you your help!

[pala]

34:06 and 34:18 it's perMaNent, not pernament 😊

32:25 Hell world --- nice freudian slip, but quite accurate! 😅

[seanfang]

This is an amazing tutorial, very informative and concise! Thank you so much ♥
