ansible-dev is a simple CLI tool that integrates with Vagrant to enable users to define, develop, and test Ansible playbooks, roles, and modules. It allows users to define and manage infrastructure resources and uses the providers automation engine to provision and run plays.
By utilizing Ansible's playbooks, roles, and modules, developers can automate the deployment of software applications across multiple hosting providers, reducing the time and effort required to manage complex infrastructure environments. These playbooks, roles, and modules enable developers to create, manage, and provision infrastructure resources like virtual machines, load balancers, and databases.
