How To Deploy Kubernetes With NetApp Trident Persistent Storage

As folks adopt DevOps principals they are using common applications to help them get there. One of those is Docker and usually in the same sentence Kubernetes is mentioned next. To review, Docker is essentially a wrapper for Linux containers (LXC), which similar to FreeBSD jails or Solaris Zones, provides a method for applications (and their dependencies) to be isolated in separate namespaces all while sharing the host system’s kernel. Docker containers are extremely portable as they just need the host server to have a LXC-compatible kernel and the Docker application installed. Kubernetes takes this concept to the next level by automating deployment, scaling, and management of containerized applications. It groups containers that make up an application into logical units for easy management and discovery. For a more detailed intro on what Kubernetes is check out the “Sources” section below. Now to the meat of the post, what is NetApp Trident and where does it fit in to the Docker/Kubernetes equation? Well according to NetApp Trident’s GitHub page, “Trident provides storage orchestration for Kubernetes, integrating with its Persistent Volume framework to act as an external provisioner for NetApp ONTAP, SolidFire, and E-Series systems. Additionally, through its REST interface, Trident can also provide storage orchestration for non-Kubernetes deployments.” In other words, Trident allows one to attach persistent storage from NetApp FAS, E-Series, or SolidFire system(s) to containers allowing applications such as databases to easily operate in a containerized environment. Below are the steps I compiled needed to not only stand up a small 3-node Kubernetes cluster but also to deploy the NetApp Trident plugin: ...
