Over the last few weeks I was setting up Kubernetes in the lab. One thing I quickly learned was managing and editing yaml files for deployments, services and persistent volume claims became confusing and hard. Even when I had things commited in github sometimes I would make edits then not push them then rebuild my […]

Using Snapshots with the Pure Storage Plugin for Kubernetes
One request from customers is not only provision persistent storage for Kubernetes but also integrate into workflows that may need to snap and copy the data for different environments. Much like we do this with powershell or python for SQL and Oracle environments to accelerate development or QA. Pure has enabled snapshots using the Pure […]
Kubernetes and the Pure Storage FlexVolume Plugin
First, if you are using Pure Storage and Kubernetes make life easier and take a look at our plugin. Now version 1.2.2 and GA. https://hub.docker.com/r/purestorage/k8s/ Make sure the follow the directions on the page to pull and install the plugin. If you are using Openshift pay special attention to the Readme. I will post more […]
Four Resources that Got Me Started with Kuberenetes
In the last post I mentioned there are resources that have already gone through that do a better job than me in helping you understand containers and Kubernetes. So if you are a virtualization admin like me and want to make 2018 the year you know enough to be dangerous I suggest the following resources. […]
Anaconda with Jupyter Notebooks on Kubernetes
WARNING: YAML Heavy post. Sorry. So I have been internally debating the best way to share this latest little thing I was working on/ learning. My goal over 2018 is to post more on migrating applications from virtual to containers managed by K8s. That transition isn’t for everything and has definetley required diving more into […]
vSphere Container Hosts Storage Networking
In the last couple of days I had a couple of questions from customers implementing some kind of container host on top of vSphere. Each was doing it to make use of either Kubernetes or Docker Volume Plugin for Pure Storage. First, there was a little confusion if the actual container needs to have iSCSI […]
Thank You – Play with Docker!
At Kubecon in Austin I was talking with my good friend Jonas Rosland about how I was getting to train a group of new Pure SE’s on Cloud Native Apps and planned on doing labs with installing docker and running apps in containers. I was going to get every student a vm and let them […]

Deploying Persistent Storage in Docker Swarm using Pure Storage Whitepaper
Spreading the word about a new paper published by Simon Dodsley on Deploying Persistent Storage in Docker Swarm. In this paper, Simon uses the Pure Docker Volume Plugin to create persistent storage for CockroachDB. That is all well and good if you want to play with CockroachDB, but also shows the foundation for you to […]
CockroachDB with Persistent Data
There IS an Official Whitepaper! While I was writing this post the awesome Simon Dodsley was writing a great whitepaper on Persistent storage with Pure. As you can see there is some very different ways to deploy CockroachDB but the main goal is to keep your important data persistent no matter what happens to the […]
