These days, many operators use tools like Puppet, Salt Stack or Ansible to ensure there is no configuration drift on servers. The next step, is to create static server images with applications already installed and there is no need for change at all: Immutable Servers.
In this meetup, we'll experiment with Packer as a tool for creating static images with everything readily installed. And we'll play around with Consul as a clever tool for managing server configurations without modifying the image. We use Docker as infrastructure because it easily runs on a laptop.
