Run job inside docker container in specific agent Jenkins

Question

I am trying to run the Jenkins pipeline steps in the Docker container in a specific agent. I could use docker to run it but the container will run in a random agent but i need it to run in specific agent.

Here's what i tried:

pipeline {
    agent { label 'agent-007' }

    stages {            
        stage("Unit Tests") {
          agent { docker 'image-name' }
          steps {
            sh 'pwd'
            sh 'hostname'
          }
        }
    }
    
}

In the documentation Specifying a Docker Label it says that in the configuration for your Jenkins job, you can specify which agent you want docker to run on. In your case, you could set "Docker Label" to "agent-007" in your job configuration. You can also specify which docker registry you want to pull from which is really handy if you use Artifactory, for instance.
