Use of --ask-vault-pass on Jenkins pipeline

Question

I am using ansible-vault in a playbook and I want to call it from Jenkinsfile. I have read that you can have the password in a file and just call it like that but I want to do it using the --ask-vault-pass.

I created the credential (secret text) on Jenkins and I want to use it but I don't know how. Been searching around the internet but all I see are questions regarding the usage of the ansible-vault password in a file.

This would be the code:

pipeline {
    agent none

    environment {
        ANSIBLE_VAULT=credentials('ansiblevault')
    }

    stages {
        stage ('Start docker node via Ansible') {
            agent { label 'ansible_slave' } 
            steps {
                sh 'ansible-playbook /etc/ansible/instance_start_stop.yml --ask-vault-pass -i hosts --user user1 --key-file /home/user1/.ssh/id_rsa'
            }
        }
    }
}

How could I use the credential in this case? Thanks!
