Fun with PKS, K8s, VCP, StatefulSets and Couchbase

After just deploying the newest version of Pivotal Container Services (PKS) and rolling out my first Kubernetes cluster (read all about it here), I wanted to try to do something a bit more interesting than just create another persistent volume claim to test out our vSphere Cloud Provider since I had done this  a number of times already. Thanks to some of the work I have been doing with our cloud native team, I was introduced to StatefulSets. That peaked my interest a little, as I had not come across them before.

Project Hatchway hitting the mainstream – persistent storage for containers

Regular readers will be aware that I “dabble” from time to time in the world of Cloud Native Apps. For me, a lot of this dabbling is trying to figure out how I can go about providing persistent storage to container based applications. Typically this in the shape of container volumes that are carved out of the underlying storage infrastructure, whether that is VMFS, NFS, vSAN or even Virtual Volumes. VMware Project Hatchway has enabled me to do this on multiple occasions. Project Hatchway was officially announced at VMworld 2017, but I’ve been working with this team since the early…

Project Hatchway – VMware Persistent Storage for Containers

Earlier yesterday, I had the opportunity to sit in on a VMworld 2017 session delivered by one of my colleagues, Tushar Thole. Tushar presented “Project Hatchway” to the audience, and like the description of this post suggests, this is all about providing VMware persistent storage to containers. In a nutshell, volumes can now be created on VMFS, NFS and on vSAN in the form of VMDKs, and these volumes can now be consumed by containers instantiated within a container host, i.e. a virtual machine. But there have been some interesting new enhancements which Tushar shared with us in the session.
