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.
its Docker image is full of security vulnerabilities, wt ... i already tried even the alpine tag, still have around 20 vulnerabilities and some of them critical
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 TH-cam. Thanks👍
Literally this was the best video on Jenkins that I've ever seen 🔥 I loved the way of your explaning concepts and giving demonstration 🤩 Thank you so much ♥ Love and Support from India 🇮🇳
Really great video. It just took me some time to understand that either using the socket container or localhost as Docker Host URI eventually the agent will run on the same daemon - as I created the Jenkins container with bind mounting the docker binaries (I am using Ubuntu as wsl)
This is a top tier video. Covers the essentials well and also went over the background of how to set up agents and a jenkins master node. Look forward to your other videos.
Thank you so much! This tutorial is basic and that makes it great! I followed it using vm with centos and aws free tier account, worked both times flawlessly.
so for this was the best video on Jenkins that I've ever seen. the way u explained everything i understood on point. thanks for the video. subscribed to ur channel
just suddesting to add docker-compose.yml to your repo Example of what am using on my computer below version: '3' volumes: jenkins-data: jenkins-docker-certs: services: jenkins: image: jenkins-local:latest container_name: jenkins_server_container restart: on-failure ports: - 8080:8080 - 50000:50000 environment: - DOCKER_CERT_PATH:"/certs/client" - DOCKER_TLS_VERIFY:1 - DOCKER_HOST:"tcp://docker:2376" volumes: - jenkins-docker-certs:/certs/client:ro - jenkins-data:/var/jenkins_home
Thank you for this video. You covered all that I needed to know about Jenkins in just an hour. You're an excellent teacher and have earned my subscription :)
43:39 whats the correct jdk version for ARM ? im getting an error: **com.github.dockerjava.api.exception.DockerClientException: Could not pull image: no matching manifest for linux/arm64/v8 in the manifest list entries**
Very well and detailed explanation in simple words.. I'm glad I get this video..now my almost 70% concepts are cleared with these videos.. Thanks DevOps Journey!!
Well, my company's pipeline is a scripted pipeline, they asked me to do error handling, i had never seen jenkins before, i saw your video, and i still don't understand it. Your video was great and i now understand the basics of Jenkins. Now i just need to understand my company's Jenkinsfile.
Very nice video! However, since I do not know what are Docker cloud agents, I need to spend some time studying that. The topic at 00:33:40 jumped too fast for me. At 00:41:11, what is jenkins/agent-alpine-jdk11, I do not have one. Should I create on on dockerhub, a image with python and nothing else?
Jenkins UI has updated since this video so there may be small differences in how your Jenkins looks vs mine. If you are running into issues with the docker build - you can pull the image I used from my registry. github.com/devopsjourney1/jenkins-101/blob/ebc93f5c71af49427149d6f1a29d94a2520b1bb6/readme.md?plain=1#L14
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
Jenkins has updated their image and python is no longer installed on it. What you could do is docker exec into the container and install python. You can also setup the dockerfile to install python and create a new image. I'll see if I can update the dockerfile to do that
@@DevOpsJourney docker exec into the container and installing python does not work, because it requires root user password . Since default user is jenkins and not the root. Would be great if you could check that!
@@dineshm3309hey there, if you specify -u 0 it logs you into the container as root. You can try the below command: docker exec -u 0 jenkins-blueocean apt install python3-pip -y I also updated the Dockerfile to install python if you rebuild the image.
@quicknik107 I updated the dockerfile, Python is now included when you build the image. You can also go inside the container and install python. This command should work: docker exec -u 0 jenkins-blueocean apt update docker exec -u 0 jenkins-blueocean apt install python3-pip -y
Thank you! This is a nice comprehensive tutorial. I have one question: what if my jenkins master runs on a server and I want to install the docker agent on my local machine? How could I connect the local docker agent to the server instance in this case?
Thank you very much. This was extremely beneficial and straight to the point. Could you please cover the topics of parameters and multi-branch pipelines in Jenkins?
Thank you so much, you teach really well. Almost done with this, had to check if you had anything on Ansible too, yay! there is.... I let the ads run fully too as my little way of saying thank you....
Merci pour la vidéo , c est un cours complet de jenkins ça m'a aidé à comprendre en gros le principe et les manipulations que je pouvais faire dessus !!
After creating the container for the agent, it starts and then stops and restarts in a loop. I can see the following output but have no clue why? socat[1] E exactly 2 addresses required (there are 3); use option "-h" for help Edit : fixed it, was a typo
Really good tutorial, everything works and goes smoothly as you explained. However in RHEL I had to install docker-podman to use docker as podman and crun package so when creating the container instead of using docker run i had to use docker run --runtime /usr/bin/crun or when using the Docker file i had run : docker build --runtime /usr/bin/crun -t
44:09 So the Cloud container is like using a different user on the local machine if I intended to build this way? So, after the build is complete it will copy the builded file to the deploy container?
Hi Brad, really thanks for such an amazing course, and It's true guys when he said this is one of the most comprehensive course on TH-cam. I have one question brad, could you tell me the website you've shown at the beginning to find Jobs ?
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!
Thank you! Best practice is the master is reserved for scheduling jobs and agents do the actual builds. In our case - the master server is running inside a docker container already. While running a docker container from within a docker container is possible it can present many problems. I hope that makes sense.
@@DevOpsJourney Just to make sure I got things right, let's say the master server is running on a VM or in a dedicated server. Then it is possible to run docker agents within the Jenkins master. Right?
thanks, i got an idea of how the Jenkins work and other part of plugins to connect the server or clouds with-in, pipeline setup stages, new project and source management with configuration of docker image as an agent is good..
Hello @DevOps Journey, Thank you very much for the course. On the other hand, I wanted to know your opinion on using Pipeline's in built support for the usage of Docker, compared to creating the Docker cloud agent manually. Provided that the Docker and the Jenkins are running on the same server, is it is really required to create Docker cloud agent manually OR using Pipeline's in built support is enough? OR, in which situation, it is needed to create Docker cloud agent? Thank you.
Hi Brad, great video. I did have a doubt. The part where you run Jenkins in Docker on your personal machine sort of flew over my head (especially the StackOverflow article). I was able to complete the tutorial by following along, but I did not understand why we do this and the logic behind it. Could you please elaborate on that part?
How do we decide what goes in the dockerfile vs the docker run command? We can add environment variables and the volumes to the dockerfile instead couldn't we?
Very informative material and one of the few devops videos where I understand the accent. The only minus is the video skips some critical set up steps especially for a beginner so you spend more time pausing trying to google or research the missing steps
