Ansible Role: Deployment

An Ansible role that deploy your application just the same way like Capistrano.

What means Capistrano way?

Capistrano is software written in Ruby, which allows you to deploy your application on remote node.
Here is how it works:

1. On remote node you should have in project workdir directories /shared, /repository and /deployments.
2. In /repository directory there is a copy of your source repo (GIT/SVN etc.)
3. When you do deploy, capistrano copies repository directory into /deployments dir.
   Name of copied directory is different - it’s always current timestamp (like /deployments/20171108123453).
4. Next step is to make symlinks of all directories/files from /shared directory into the new deployment directory.
   It allows you to share upload dir or logs directory between deployments.
5. Last step is to create or change symlink /current to point to the latest deployment from /deployments
