Installation

Build the Jenkins BlueOcean Docker Image (or pull and use the one I built)

docker build -t myjenkins-blueocean:2.414.2 .

#IF you are having problems building the image yourself, you can pull from my registry (It is version 2.332.3-1 though, the original from the video)

docker pull devopsjourney1/jenkins-blueocean:2.332.3-1 && docker tag devopsjourney1/jenkins-blueocean:2.332.3-1 myjenkins-blueocean:2.332.3-1

Create the network 'jenkins'

docker network create jenkins

Node affinity conflict

Hi,
I get the following error during deploying jenkins to minikube: 1 node(s) had volume node affinity conflict minikube. My volume data:

kubectl get pvc -n devops-tools
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
jenkins-pv-claim Bound jenkins-pv-volume 10Gi RWO local-storage 25m

kubectl get pv jenkins-pv-volume
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
jenkins-pv-volume 10Gi RWO Retain Bound devops-tools/jenkins-pv-claim local-storage 25m

Any idea?

[Discussion] Getting `jenkins` communication issue with docker daemon

Hi @devopsjourney1! I have hard finding about setting up jenkins pipeline with docker agent. Since I have followed these steps from the docs here, but when I try to follow the steps from ur video, I am failing to create a label docker agent.

Is it necessary to install jenkins through docker to establish connection b/w docker host and jenkins server?

When I skip the docker installation as I have done through kubernetes and follow the docker socket connection like this docker network create jenkins and docker run -d --restart=always -p 127.0.0.1:2376:2375 --network jenkins -v /var/run/docker.sock:/var/run/docker.sock alpine/socat tcp-listen:2375,fork,reuseaddr unix-connect:/var/run/docker.sock, I still fail to make the connection successful. Any thoughts here plz?
