Kubernetes on vSphere

kubernetesI’ve talked a lot recently about the various VMware projects surrounding containers, container management, repositories, etc. However one of the most popular container cluster managers is Kubernetes (originally developed by Google). To use an official description, Kubernetes (or K8S for short) is a “platform for automating deployment, scaling, and operations of application containers across clusters of hosts”. So this begs the question about how easy is it to deploy K8S on vSphere. I have already documented how K8S can be deployed on Photon Platform. But can you easily deploy Kubernetes on a vSphere infrastructure. The answer now is that it is relatively easy. This necessary scripts are now included in K8S version 1.4.5, which went live recently (October 29th). Let’s look at the steps involved in deploying Kubernetes on vSphere in more detail.

What’s new in vSphere 6.5 Core Storage

Hello from VMworld EMEA in Barcelona. Well, we can finally talk about vSphere 6.5 today. In this post, I want to highlight a number of new and enhanced features that you will find in vSphere 6.5 related to core storage. I am not going to discuss Virtual SAN (VSAN), Virtual Volumes (VVols) or I/O Filter enhancements (VAIO) specifically in this post, although you will no doubt see some new features tie directly into the latter. Instead, I want to talk about those features that are specific to core storage.

Some nice enhancements to Docker Volume Driver for vSphere v0.7

dockerThis week I am over at our VMware HQ in Palo Alto. I caught up with the guys in our storage team who are working on our docker volume driver for vSphere to find out what enhancements they have made with version 0.7. They have added some cool new enhancements which I think you will like.

First, this has been designed specifically for docker version 1.12. So the first thing you will have to do is to make sure that your docker is at this latest version. For most distros, this is quite a simple thing to do. But since I predominantly use our Photon OS distro, which ships with docker version 1.11 currently, there are a few additional steps to consider. To update the version of docker on Photon OS, you can use the following steps:

Container Volumes in VIC v0.4.0

I mentioned yesterday that VMware made vSphere Integrated Containers (VIC) v0.4.0 available. Included in this version is support for container volumes. Now, as mentioned yesterday, VIC is still a work in progress, and not everything has yet been implemented. In this post I want to step you through some of the enhancements that we have made around docker volume support in VIC. This will hopefully provide you with enough information so that you can try this out for yourself.

Getting Started with vSphere Integrated Containers v0.4.0

I’ve been working very closely with our vSphere Integrated Container (VIC) team here at VMware recently, and am delighted to say that v0.4.0 is now available for download from GitHub. Of course, this is still not supported in production, and is still in tech preview. However for those of you interested, it gives you an opportunity to try it out and see the significant progress made by the team over the last couple of months. You can download it from bintray. This version of VIC is bringing us closer and closer to the original functionality of “Project Bonneville” for running containers as VMs (not in VMs) on vSphere. The docker API endpoint now provides almost identical functionality to running docker anywhere else, although there is still a little bit of work to do. Let’s take a closer look.

Docker Volume Driver for vSphere

dockerThis is a really cool development. There is now a docker volume driver for vSphere which we just made public last night, and is now available for tech preview. This will allow customers to address persistent storage requirements for Docker containers in vSphere environments. Basically, it allows you to create a VMDK, and use this VMDK as a persistent storage volume for containers. In the following posts, I will outline the steps involved in getting started with Docker Volume Driver for vSphere. In essence, there are 4 steps:

  1. Install the docker volume plugin on ESXi host. I was running ESXi 6.0U2.
  2. Deploy Photon OS VM (although you can also use Ubuntu)
  3. Install the docker VMDK plugin on VM
  4. Create docker volume and run container to consume it

All the pieces to get you started are available on github here.
