Jenkins Shared Library return executable docker command

Question

Is it possible to get a shared library to retune a docker run command?

I have the following,

scr/docker_run.groovy

def ubuntu() {
  echo "docker run --rm " +
         '--env APP_PATH="`pwd`" ' +
         '--env RELEASE=true ' +
         "-v \"`pwd`:`pwd`\" " +
         "-v /var/run/docker.sock:/var/run/docker.sock " +
         "ubuntu" 
}

Jenkinsfile

@Library('pipeline-library-demo') _

pipeline {
    agent {
        node {
            label params.SLAVE
        }
    }

    parameters {
        string(name: 'SLAVE', defaultValue: 'so_slave')
    }

    stages {
        stage('ubuntu') {
            steps {
                script {
                    sh docker_run.ubuntu ls -lah
                }
            }
        }
    }
}

I have tried different things inside the groovy file, such as echo, sh, call, all returning errors.

Any help would be great

If you are using DSL style pipeline you should define Steps in your shared library not directly a function in the src/ directory. Should follow the directory structure defined here https://jenkins.io/doc/book/pipeline/shared-libraries/ Then you can define a Step like

vars/mystep.groovy

def call() {
    this.sh("docker_run.ubuntu ls -lah");
}

And calling from you pipeline as:

@Library('pipeline-library-demo') _

pipeline {
    agent {
        node {
            label params.SLAVE
        }
    }

    parameters {
        string(name: 'SLAVE', defaultValue: 'so_slave')
    }

    stages {
        stage('ubuntu') {
            steps {
                mystep
            }
        }
    }
}
