![]() In addition we need to install a plugin that manages the hosts file in guest machine. Installing Vagrant is easy, check out the download page and follow the instructions. Expose the HelloWorld endpoint to the host from VM.Run Vagrant VM, provision it with Ansible using Docker container as a provider.Write a docker image to be used as provider for Vagrant.Package, build and deploy an application using Ansible.Write a RESTfull API which exposes resource to say hello to the world.The great thing about Vagrant is that you can use all modern provisioning tools (e.g Chef, Puppet, Ansible) to install and configure software on the virtual machine. It is easy to configure, and by default comes with support of the providers such as Docker, VirtualBox and VMware. In fact, if you want to use Docker on your. But different because Vagrant gives you Virtual Machines in minutes and Docker gives you Linux Containers in milliseconds. So they are similar because they both take a config file. It comes with a great CLI which makes interaction with Docker engine really easy and supports versioning of the images. Docker is Linux-only tool that lets you specify Linux Containers ( as a Dockerfile) to deploy to any host running Docker. It shares the same kernel and filesystem of the machine where it is hosted. It’s important to understand that Docker is not a VM. Dockerĭocker is a nice toy to build and deploy any kind of application into lightweight Linux containers. ![]() Resources required Another fundamental difference is the number of resources that both platforms require to cope with the task of deploying a virtual environment. In practice, you can pass your Ansible Playbooks to a third person and in couple of minutes he/she will have an idea how you manage provisioning for your product. While Vagrant allows you to create an entire virtual machine, Docker packages your applications into miniature containers deployed in a predictable scenario. With Ansible it is possible to automate provisioning, orchestration, configuration management and deployment of applications.Īnsible Playbooks are written using YAML syntax, so that you have it in human-readable format and no complex knowledge is required to understand what it does. Here is a quick overview about the tools we are going to use: AnsibleĪnsible is an IT automation engine written in Python. Having the setup it will be possible to run the application in any environment where the prerequisites are installed. In the following article we’ll see how Ansible, Docker and Vagrant can be used to provision and install necessary software on environment where you can build and deploy an application. Fortunately there are tools and engines coming for help. This docker vs vagrant table shows the main differences between both virtual systems: For people that want to collaborate with other users, Docker is the better option. Giving the challenges of building and maintaining a complex software it’s really hard to manage the provisioning, orchestration, build and deployment of applications easily. ![]()
