Among the configuration administration instruments to be had, Ansible has a few detailed benefits - it is minimum in nature, you don't want to put in something in your nodes, and it has a simple studying curve. This sensible advisor exhibits you ways to be effective with this device fast, no matter if you are a developer deploying code to creation or a method administrator searching for a greater automation answer. writer Lorin Hochstein indicates you ways to put in writing playbooks (Ansible's configuration administration scripts), deal with distant servers, and discover the tool's actual energy: integrated declarative modules. you will find that Ansible has the performance you wish and the simplicity you want.

There are over 200 of these, and the official Ansible reference documentation on the modules is quite good. I only cover the basic features of the templating engine that Ansible uses, Jinja2, pri‐ marily because I find that I generally only need to use the basic features of Jinja2 when I use Ansible. If you need to use more advanced Jinja2 features in your tem‐ plates, I recommend you check out the official Jinja2 documentation. I don’t go into detail about some features of Ansible that are mainly useful when you are running Ansible on an older version of Linux.

Let’s look at an example: installing the nginx web server and configuring it for secure communication. j2 Some Preliminaries Before we can run this playbook against our Vagrant machine, we need to expose ports 80 and 443, so we can access them. As shown in Figure 2-1, we are going to configure Vagrant so that requests to ports 8080 and 8443 on our local machine are forwarded to ports 80 and 443 on the Vagrant machine. info the web server running inside Vagrant at http://localhost:8080 and https://localhost: 8443.
