Jenkins: Scripted Pipeline – Production environment job confirmation step

By | 03/19/2019
 

We have jobs which have to be executed on a Dev and Production environments via a Scripted Pipeline.

In such jobs, there are tasks to execute CloudFormation upgrades on an infrastructure or Ansible playbooks to update servers configuration.

To avoid an accidental execution of a Production job I want to have some confirmation step before this job will be started and will do any changes in an environment.

Let’s use pipeline-input-step and its class BooleanParameterDefinition.

Add a verify() function:

def verify() {

    stage('Verify') {

        def userInput = input(
            id: 'userInput', message: 'This is PRODUCTION!', parameters: [
            [$class: 'BooleanParameterDefinition', defaultValue: false, description: '', name: 'Please confirm you sure to proceed']
        ])
        
        if(!userInput) {
            error "Build wasn't confirmed"
        }
    }
}

In the if(!userInput) condition here the userInput value will be check for true or false, by default the false will be set here.

Now add this function execution:

node {
    
    switch("${env.LIMIT}") {
        case "backend-production":
            verify()
            echo "Run job"
            break;
        default:
            echo "Dev deploy"
            break;
    }
    
}

Here we checking the LIMIT parameter value which can contain a backend-productionbackend-dev, or backend-test.

If its value will be equal to the backend-production – then the verify() first will be executed and only after it – other build/deploy steps.

If any other – then just tasks will be started.

Let’s check it – start a job:

User input request appeared:

Set mark, press Proceed:

And build is started:

Now let’s re-run it but at this time let’s “forget” to set a mark and just press Proceed:

Here the  if(!userInput) was applied and the result is the  error.

And last check – with the Abort:

Done.
