Run command in docker container not working

For example if you want to run tests in container.

This is the simple example:

pipeline {
    agent {
        docker { image 'node:7-alpine' }
    }
    stages {
        stage('Test') {
            steps {
                sh 'node --version'
            }
        }
    }
}

you will get this error:

How about create jenkins slave

Hi , How about create jenkins slave in k8s cluster.

questions

Hello.

I am following your guide, but here's some questions.

If I need update jenkins or jenkins plugin version or add some plugin,
is it possible to have all job's history and log?
Please explain(add to readme file) this case.

and please consider more production env. friendly.
You can assume there's 3 servers, (I guess one is for jenkins master, others for jenkins agent)
how to use/set kubernetes and
how to build at agent server.
This is related https://github.com/eldada/jenkins-pipeline-kubernetes
I see below lines in Jenkinsfile.
// In this example, all is built and run from the master agent { node { label 'master' } }

Thank you.
