Ionic Framework push with Jenkins Declarative

This gist has been created to document one successful way I have found to use Declarative pipeline + nodeJS + Ionic Framework and preview the work through the Ionic SaaS Platform. More on this can be found on the Ionic website

Prerequisites

Jenkins/Jenkins:LTS
Amazon EC2 plugin:1.38
NodeJS Plugin:1.2.4
NodeJS 8.9.4

Env Setup

For this task, I am currently using Jenkins LTS docker image, runnning on an EC2 instance. No executors are being used on the master(BAD PRACTICE) I am currently using the EC2-Cloud plugin to create slaves from an AMI.

Jenkins Configuration

I am currently using a Multi-branch pipeline. I connect to my Bitbucket repositories and use segmented Declarative Pipeline based executions.

Variable Declaration

There are a number of variables that I used to parametrize and hide credentials or other attributes in Jenkins

environment{
//This is the unique identifier of your ionic project
IONIC_PROJECT = "abc12345"
//This is the credential object that Jenkins has to login to Ionic
IONIC = credentials("my_Ionic_user")
//This is a secret text file that I use to store the SSH key used to talk to Ionic
KEY = credentials("jenkins_Private_Key")
}

Jenkinfile Code

Below is the raw code for how we execute the upload to Ionic SaaS

//Define this stage as part of my pipeline
stage('IonicView Deploy') {
	//set where I am going to run the stage.
    agent { label 'jenkins_worker' }
        steps {
	    //Cleaning the workspace helps me know I start fresh
            cleanWs()
	    //checkout the code I want deployed to Ionic
            git branch: '$BRANCH_NAME', credentialsId: 'bitbucket_serviceaccount', url: "${GITHUB_URL}"
	    //Informs me of the repo layout when I download it. This is more error reporting.
            sh "ls -ltra"
			
	    /**Even though we will use shell, I always try to use this nodejs block to ensure node is installed
	    In this block I do a number of things. I make sure I have the Ionic framework installed, I reverify the linking 			    between my code and the Ionic project, and then I deal with connecting via SSH to Ionic.
			
	    Once that is all done, I push the code to Ionic
	    **/
