Vagrant provision11/21/2023 ![]() This provisioner allows us to provision our guest machine (VM), using an Ansible Playbook, effectively combining the power of the 2 tools. For example, it provides a file provisioning module, which allows to upload a file or directory from the host machine to guest machine (VM), and a shell provisioning module, which allows to upload and execute a shells script on the guest machine.Īnother provisioning module it provides is the Ansible Provisioner. 2 Vagrant provides a number of different provisioning modules. Let's discuss the topic of provisioning. Provisioning is the concept of preparing and equipping a machine to allow it to provide (new) services to its users. Using the roles concept, we have a modular approach to system provisioning, allowing us to re-use provisioning tasks, and define the layout of a system by simply applying the required role or set of roles. Or we can create a role "JBoss BPM Suite", which depends on the role "JBoss EAP", which will provision JBoss BPM Suite on top of JBoss EAP on the target machine. we can create a role for a "JBoss EAP" server, which will provision JBoss Enterprise Application Platform on the target machine. The roles concept allows us to modularise the provisioning tasks, depending on the functionality that is provided. A Playbook is simply a text-file that defines which roles get assigned to which machines. However, being a very light-weight, agentless platform, it's also very well suited to run on a simple laptop to provision and configure, for example, development VMs.Īnsible works with the concept of a Playbook. It's targeted at managing large IT deployments, allowing to easily provision and configure a vast array of machines and their configurations. 1Īnsible allows us to define and orchestrate the provisioning of our systems. It uses no agents and no additional custom security infrastructure, so it's easy to deploy - and most importantly, it uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to describe your automation jobs in a way that approaches plain English. AnsibleĪnsible is a radically simple IT automation engine that automates cloud provisioning, configuration management, application deployment, intra-service orchestration, and many other IT needs. When we want to create a VM on another development environment, we simply run vagrant up to recreate the VM. Instead of having to save a large, fully pre-defined, VM image, we simply checkin our Vagrantfile in our version control system. One of the powers of Vagrant is that it allows you to store your entire VM definition in just a single file from which the same VM can be created and re-created over and over again. To stop the VM, we simply execute the command: ![]() ![]() Once Vagrant has been run, the VM will be fully defined, configured, up-and-running and ready for use. This will automatically configure a new virtual machine (in my case in VirtualBox), download the base-box (if it has not been downloaded already), and provision the virtual machine (more about provisioning later). Once configured we can start our VM by simply executing the command: We can describe what base-box we want to use for our virtual machine (a base-box is a minimal virtual machine with a minimal set of tools on which we use as a base on top of which we will build our own environment), the number of CPUs we want to assign to the VM, the amount of RAM, the network configuration, etc. It's a lightweight toolset that allows to define and describe the layout and structure of a virtual machine in a single file, the Vagrantfile. Vagrant is my tool of choice when it comes to creating and managing my virtual machine (VM) development boxes. Say hello to Vagrant and Ansible! Vagrant Hence, we want to have an automated solution in which we can (declaratively) define the layout and configuration of our virtual machine. Manual work is error prone, hard to reproduce and definitely hard to version control. Obviously this can done by hand, but what's the fun in that?! This means that I need to create, install, provision and deploy a virtual machine that contains all the required tools and code to successfully run the lab sessions. The lab-sessions require a pre-installed and pre-provisioned virtual machine, which contains all the material required to run the lab. One part of the workshop is a four-hour lab that guides the attendees through the development of JBoss BPM Suite 6.x processes, rules and applications (note that this workshop is available to our customers, please contact your Red Hat account manager or local Red Hat sales representative for more information), but I'm going to be sharing part of the story with you today. Over the last couple of weeks, I've been working on some Red Hat JBoss BPM Suite workshop material.
