Jenkins Pipeline is the way to go. Have a look at this blog: https://www.edureka.co/blog/jenkins-pipeline-tutorial-continuous-delivery

@Sirajul's explanation is really good.

Jenkins Pipeline is designed to easily use Docker images as the execution environment for a single Stage or the entire Pipeline. Meaning that a user can define the tools required for their Pipeline, without having to manually configure agents. 

Practically any tool which can be packaged in a Docker container, can be used with ease by making only minor edits to a Jenkinsfile.

Jenkinsfile (Declarative Pipeline)

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

Jenkinsfile (Scripted Pipeline)

node {
    /* Requires the Docker Pipeline plugin to be installed */
    docker.image('node:7-alpine').inside {
        stage('Test') {
            sh 'node --version'
        }
    }
}

When the Pipeline executes, Jenkins will automatically start the specified container and execute the defined steps within it:

[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] sh
[guided-tour] Running shell script
+ node --version
v7.4.0
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
