VMware has just officially announced Photon OS 1.0. This follows on from the RC (Release Candidate) announcement back in late April. For those of you who are not familiar with Photon OS, this is a minimal Linux container host (in the form of a Virtual Machine), optimized to run on VMware products such as ESXi. It can run containers which adhere to Docker, rkt, and the Pivotal Garden container specifications.
In some earlier post, I provided instructions on how one could deploy Kubernetes (K8S) on Photon Controller using the built-in photon controller CLI. In this next post, I want to show you how Kubernetes can be deployed natively, using kube-up and kube-down, on Photon Controller v0.9. In this example I am using Photon OS, a minimal Linux container host, optimized to run on vSphere (and other VMware products). Now in order to deploy K8S, a number of additional tooling needs to be added to Photon OS. The requirements are highlighted in this earlier blog post. Once all the necessary components…
I took another opportunity this week to look at our new Docker Volume Driver for vSphere which is currently in tech preview. This time I wanted to see how it behaved on Virtual SAN (VSAN). What I wanted to do is query the layout of the VMDK storage object on VSAN, and how an administrator can query its layout from vCenter server, but also from RVC, the Ruby vSphere Console. There might be a situation where you need to to query this information. My colleague, Wiliam Lam, has already added some information about how you can deploy volumes with different…
With the release of Photon Controller v0.9, there were a lot of nice new features. My colleague Sarge has a good bit of detail on the new features in his blog post. One of the interesting additions, in my opinion, is the introduction of support for kube-up and kube-down for deploying Kubernetes frameworks (I will have a blog post on this ready to go shortly). If you are a regular reader, you might remember that we had another, more photon controller-centric way of rolling out K8S on Photon Controller that I wrote about here. That was using the “cluster” concept…
I created a short, 5 minute video to highlight the different parts of the docker volume driver for vSphere “tech preview” to accompany the blog post I created earlier. It will show what is needed on the ESXi host, and on the VM running containers. Hope you find it useful.
Another container framework that VMware customers can evaluate on Photon Controller is Kubernetes, developed by Google and now open-sourced. Kubernetes is another popular framework that allows customers to automate, manage and scale containers. Just like my previous article on Mesos and Docker Swarm, the Photon Controller and Kubernetes deployment steps are very similar. While I will show the additional steps required to get Kubernetes deployed, I wanted to focus once again on the “what do I do now?” question as this is pretty much the most common question from folks who have gone through the deployment of the Photon Controller…
This 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: Install the docker volume plugin on ESXi host. I was running ESXi…
