¿How to configure an Agent jenkins/inbound-agent with docker installed?
To follow the course, I installed my jenkins with HELM in k8s.
I am struggling to set up an Agent with docker installed.
I want to set up this one https://github.com/jenkinsci/jnlp-agents/tree/master/docker
https://hub.docker.com/r/jenkins/jnlp-agent-docker
Anyone can help me to substitute jenkins/inbound-agent:4.11-1 for jenkins/jnlp-agent-docker so I can have docker in the Agent?

@Miguel_Angel have you considered using kubernetes agent which launches a pod (with jnlp embedded into it as a container in addition to actual job container).
Here is a sample Jenkinsfile (created from my existing pipeline, not tested)
FIle:
Jenkinsfile
pipeline { agent { kubernetes { yamlFile 'build-agent.yaml' defaultContainer 'alpine' idleMinutes 1 } } stages { stage('Sample Stage') { parallel { stage('this runs in a pod') { steps { container('alpine') { sh 'uptime' } } } } } } }
If you use configure above you would also have to add build agent config in its own file. For example,
file :
build-agent.yaml
apiVersion: v1 kind: Pod metadata: labels: app: xyz spec: containers: - name: alpine image: alpine command: - cat tty: true
Let me know if this could help.

more info.
I created this pipeline
pipeline {
agent { label 'docker' }
stages {
stage('Run docker') {
steps {
sh 'docker version'
}
}
}
}I added this agent
The agentpods get error
