Do it by hand
You could do this at least once - a useful learning experience (especially for when things go wrong).

Automate it!
I'm probably preaching to the converted here :)

Infrastructure with Terraform
Declarative configuration for infrastructure
» Multi-cloud / multi-provider
» Repeatable
» Easy to consistently create / destroy / re-create infrastructure
But Terraform is only half the story. Once the infrastructure has been created, how do you get Docker itself deployed and configured?
![Page 62: The cloud is my laboratory, Adam Friedman](https://reader034.fdocuments.net/reader034/viewer/2022042907/5877a8d01a28ab826e8b682d/html5/thumbnails/62.jpg)
Software with Ansible
» Hardly the only option out there, but if you're experimenting with throw-away systems then it's a good choice because it's just SSH (no master / agents to deploy)
» Chef Solo (or Chef Zero) is an alternative, but may still require more work to bootstrap each node
» Quick to get started (just run commands or modules on target machines)
» Scales up to Roles + Playbooks for repeatability
» Not great for managing large numbers of machines
![Page 63: The cloud is my laboratory, Adam Friedman](https://reader034.fdocuments.net/reader034/viewer/2022042907/5877a8d01a28ab826e8b682d/html5/thumbnails/63.jpg)
Software with Ansible
» Can be run from Terraform (via a plug-in provisioner) but it's a lot easier to run it separately while you're experimenting.
» There are Ansible inventory plugins that can read a Terraform state file (so it knows server roles, host names, IP addresses, etc).
» Ansible Galaxy has modules for everything, including Docker (hint, hint)
» Beware if you are deploying an OS with only Python 3.x (Ansible needs 2.x)

A quick detour: Docker from simple to complex» Stand-alone
» Docker
» Orchestrated
» Local
» Docker Compose
» Clustered
» Docker Swarm
» Clustered with GUI
» Cattle / Rancher
» Kubernetes
» Mesos / Marathon
» Kitchen Sink
» Mantl
Note that simple and easy-to-use are not the same thing :)
![Page 65: The cloud is my laboratory, Adam Friedman](https://reader034.fdocuments.net/reader034/viewer/2022042907/5877a8d01a28ab826e8b682d/html5/thumbnails/65.jpg)
Cisco Mantl
» Mantl is a microservices platform based on Docker, Mesos / Marathon, Consul, Traefik, Kubernetes, Calico, Contiv, etc (pretty much everything but the kitchen sink).
» Because it already includes several popular systems that extend / orchestrate Docker, it’s a useful starting point if you’re stuck trying to work out how to deploy or integrate a particular component

Cisco Mantl
» Mantl is deployed using Terraform with Ansible, and can therefore be deployed on a variety of clouds by swapping out Terraform modules as required.
» Their Ansible inventory plugin understands which cloud provider was used to create the infrastructure and so Ansible playbooks can adjust their behaviour to suit (if required).

» Digital Ocean is fast Add Terraform and you can repeatedly create and destroy environments in seconds, rather than minutes.
» Obviously you can use AWS / Azure, too (or Dimension Data Cloud Control) but for quick-and-dirty experiments I prefer the simplest thing that works).
» Create an Ansible playbook to install Docker
» Start small - put everything in a single playbook and then move stuff out to separate reusable roles when needed
