As I am going to be doing some talks around next-gen applications at this year’s VMworld event, I took the opportunity to revisit Pivotal Container Services (PKS) to take a closer look at how we can set persistent volumes on container based applications. Not only that, but I also wanted to leverage the vSphere Cloud Provider feature which is part of our Project Hatchway initiative. I’ve written about Project Hatchway a few times now, but in a nutshell this allows us to create persistent container volumes on vSphere storage, and at the same time set a storage policy on the…
This post will walk you through a simplified PKS (Pivotal Container Service) deployment in my lab. The reason why I say this is simplified is because all of the components will be deployed on a single flat network. PKS has a number of network dependencies. These include the bosh agents deployed on the Kubernetes (K8s) VMs being able to reach the BOSH Director, as well as the vCenter server. Let’s not get too deep into the components just yet – these will be explained over the course of the post. So rather than trying to set up routing between multiple…
Regular readers will have noticed that I have been doing a bit of work recently with docker swarm, and what you need to do to get it to work on VMs running on vSphere. The reason why I had taken such an interest is because I wanted to look at a new product that our Project Hatchway team have been cooking up, namely vFile. In a nutshell, vFile provides simultaneous, persistent volume access between nodes in the same Docker Swarm cluster. In some ways, it can be thought of as an extension to vDVS, the vSphere Docker Volume Service (from…
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…
