HOWTO

• Configure agents  https://www.howtoforge.com/tutorial/ubuntu-jenkins-master-slave/
• Agent x node https://stackoverflow.com/questions/42050626/jenkins-pipeline-agent-vs-node
  
• Declarative pipeline syntax https://www.jenkins.io/doc/book/pipeline/syntax/
  
• Pipeline example https://www.jenkins.io/doc/pipeline/examples/
• https://www.jenkins.io/doc/book/pipeline/jenkinsfile/#using-multiple-agents

Configure Jenkins agent

agent

label 

  

   Execute the Pipeline, or stage, on an agent available in the Jenkins environment with the provided label. For example: agent { label 'my-defined-label' }

node

agent { node { label 'labelName' } } behaves the same as agent { label 'labelName' }, but node allows for additional options (such as customWorkspace).

Multiple agents

pipeline {
    agent none
    stages {
        stage('Build') {
            agent any
            steps {
                checkout scm
                sh 'make'
                stash includes: '**/target/*.jar', name: 'app'
            }
        }
        stage('Test on Linux') {
            agent { 
                label 'linux'
            }
            steps {
                unstash 'app'
                sh 'make check'
            }
            post {
                always {
                    junit '**/target/*.xml'
                }
            }
        }
        stage('Test on Windows') {
            agent {
                label 'windows'
            }
            steps {
                unstash 'app'
                bat 'make check'
            }
            post {
                always {
                    junit '**/target/*.xml'
                }

Authenticate to Azure using service principal variables

https://docs.microsoft.com/en-us/azure/developer/terraform/get-started-cloud-shell#authenticate-via-azure-service-principal

Get values for service principal and store them into env vars ARM_* 

A Service Principal is an application within Azure Active Directory whose authentication tokens can be used as the client_id, client_secret, and tenant_id fields needed by Terraform (subscription_id can be independently recovered from your Azure account details).

Set subscription to use with Terraform

https://docs.microsoft.com/en-us/azure/developer/terraform/get-started-cloud-shell#set-the-current-azure-subscription

az account set --subscription="<subscription_id>"

Export Azure principle secrets variables

- Finding latest version of hashicorp/tls...

- Installing hashicorp/azurerm v2.36.0...
- Installed hashicorp/azurerm v2.36.0 (signed by HashiCorp)

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, we recommend adding version constraints in a required_providers block
in your configuration, with the constraint strings suggested below.

* hashicorp/azurerm: version = "~> 2.36.0"
* hashicorp/tls: version = "~> 3.0.0"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
