Dockerfile based agents was the biggest game changer for Jenkins for me.

Excellent narrative style. Really appreciate your efforts ❤

[basamnath]

Amazing teaching. Just awesome and thank you

[staj]

Brilliantly done. Great Information. Thanks.

Great video! Automated deployment on a box that only exists while Jenkins is building. Surreal :)

Hi Darin

You and your videos are awesome and very informative as always. But could you please make a video on how to use docker as dynamic slave agents by building a custom docker image and use that whenever there is requirement in the job.

Thanks
Mithun

Thanks for this awesome video. Keep sharing more! One question: What if I want to use Jenkinsfile-3 with node image, curl and git but I also want to have docker installed on this image? What would be the dockerfile code like? Thanks in the advance. :D

This seems fantastic. One question : If we have Jenkins running as a docker image. Is there any problem or consideration with the setup?

[sambasivam]

how does it run at agent? is there any additional config settings missing? Everytime I run it will execute in master and throw error docker not found. any help?

[anthonywhitehead]

Hi Darin, I've been following your examples, thank you. I'm not sure if you answer questions here, but I've got a docker-compose setup with nginx and the blueocean jenkins container (created from ansible) working nicely, along with configuration as code. I'm trying to create a build agent but am stuck with and haven't been able to resolve 'got permission denied while trying to connect to the docker daemon socket'. I'd like the agent to be another docker container in docker-compose based on the inbound-agent container. Am I going around this ok, or should I just give in and create a real vm as an agent rather than a docker one?

HI Darin,

I have my Jenkins running on docker so how do i create the docker build agents. Could you please share what additional configurations are required for that

[scribblespoon]

Docker was not found. I'm guessing there are some other prerequisits other than the plugins. The documention of the docker pipeline plugin didn't help me as well.

[pazfelipe]

Hi Darin. Could you make a video showing how to execute these steps inside a jenkins docker image?

[sathishsubramanian]

Hi Darin, I have a doubt that for building docker image should we need to run jenkins inisde docker container or from war file we can use jenkins?

[master]

What if the docker host is out there on network as opposed to on Jenkins host?

[vijjisanthi]

Hello Darin currently iam running jenkins from ec2 is there any possibility to move from ec2 to ecs without loosing my data and configuration

[lalitshukla]

Thanks Sir.. Can we use a Jenkins upstream job to create multiple slaves ? if yes please explain.

[usucyev]

Hi Darren, just wondering if agent1 is running inside a docker container as I am currently seeing errors when trying to follow the guide you made in here?

[yashhirulkar]

sir i am getting this error while using docker as agent .What shud i do please?

Hey how do I setup windows server which contains docker deamon running in it as agent.. so that I can run my groovy pipeline script in dynamically created container on agent ?
