Deployment with Docker

Basics

The standard layout for a project is usually split into roles that define functionality slices with the rest of the configurations basically just supporting those roles. The basic file structure of Ansible projects looks something like this (though more complex setups are often needed):

• group_vars/all: This file is used to define variables that are used for all of your playbooks. These can be used in playbooks and templates ...
