The certified Kubernetes distribution built for IoT & Edge computing

This guide shows how to provision and manage remote Docker Hosts with Docker Machine on your OpenNebula cloud.

Infrastructure as Code (IaC) is changing the way that we’re doing things. Some people think that it’s the motorway that we have to follow and be aligned with business, as a resume they want us to be agile.

The arrival of tools such as Ansible, Puppet, SaltStack, and Chef, have enabled sysadmins to maintain modular, automatable infrastructure. This time I would like to introduce the Terraform tool.

Terraform is a provisioning declarative tool that is based on the Infrastructure as Code paradigm. Terraform is a multipurpose composition tool: it composes multiple tiers (SaaS/PaaS/IaaS).

Terraform is not a cloud agnostic tool, but in combination with OpenNebula, it can be amazing. By taking advantage of the template concept it will allow us to deploy vm’s agnostically in different cloud providers, such as AWS, Azure or on premise cloud infrastructure.

Containers are a great solution for consistent software deployments. When you start using containers in your environment, you and your team will quickly realise that you need a system which allows you to automate container operations. You need a system to keep your containers running when stuff breaks (which always happens, expect failure!), be able to scale up and down, and which is also extensible, so you can interact with it or built upon it to get the functionality you need. The most popular system for deploying, scaling and managing containerized applications is Kubernetes.
