Jenkins 2 has pipelines has a first class citizen. However, in the examples the tasks seem to be executed as a single sequence:

node {
   // Mark the code checkout 'stage'....
   stage 'Checkout'

   // Get some code from a GitHub repository
   git url: 'git@github.com:elifesciences/elife-bot.git'

   // Mark the code build 'stage'....
   stage 'Build'
   echo "Unit tests will run here"

   stage "Production"
   echo "Deploying to production environment"
}

For deployment into production system it's often useful to require manual approval; is there a way to insert a manual button to press inside a pipeline?

I have been looking for possible steps to accomplish this on the docs, to no avail.

input is the option you are looking for. Here is the way I'm using it. It's important to have the step outside a node, otherwise jenkins will hold an agent waiting for the next step. Keep in mind the second node may not use the same workspace as the first.

node {
    stage('build'){
        echo "building"
    }
}
stage('Deploy approval'){
    input "Deploy to prod?"
}
node {
    stage('deploy to prod'){
        echo "deploying"
    }
}

I did in as shown below way by reading this docs https://jenkins.io/doc/book/pipeline/syntax/

pipeline {
environment {
    BRANCH_NAME = "${env.BRANCH_NAME}"
}
agent any
stages{
    stage('Build-Initiator-Info'){
            steps{
                sh 'echo "Send Info"'
            }
    }
    stage('Build') {
        steps{
             catchError {
                sh 'echo "This is build"'
            }
         }
         post {
            success {
                echo 'Compile Stage Successful . . .'
            }
            failure {
                echo 'Compile stage failed'
                error('Stopping early…')

             }
    }
   }
  stage ('Deploy To Prod'){
  input{
    message "Do you want to proceed for production deployment?"
  }
    steps {
                sh 'echo "Deploy into Prod"'

              }
        }
  }
   }

Additionally, You can also add auto-timeout like below

        stage('build') {
        steps {
            sh  """
                # Some commands
                """
            script {
              timeout(time: 10, unit: 'MINUTES') {
                input(id: "Deploy Gate", message: "Deploy ${params.project_name}?", ok: 'Deploy')
              }
            }
        }
    }

    stage('deploy') {
        when {
            branch 'master'
        }
        steps {
            sh  """
                # some commands
                """
        }
    }

If you look it up you can also bind the jenkins input to credentials of users accessing Jenkins if you only wish to permit specific individuals to be capable of answering - it also is underpinned by the fact that your Git controls are sufficient too.

In the end I created separate test-project and prod-project pipelines, where at the end of test-project the code is merged into an approved branch.

Then, the prod-project pipeline can be set up not to trigger for every new commit so that it can be deployed on-demand.

This is just a simple example but you can trigger it however you need.

stage{
    script{
        input "Continue?"
        ...enter code here
        ...
    }
}
