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…
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…
Another framework that can be very quickly stood up on Photon Controller is Mesos. Apache Mesos is yet another cluster framework for container orchestration and availability (yes, there are many). The steps for deploying the Photon Controller Installer, deploying Photon Controller and creating the tenants, resource tickets and projects are identical to those outlines in steps 1,2 and 3 of my Docker SWARM on Photon Controller post. There is no point in repeating all of the steps here. I will highlight some of the other steps involved in deploying Mesos on Photon Controller, but I don’t really want to focus…
Every week, the VMware Storage and Availability Tech Marketing team (John Nicholson and Pete Fletcha) run a podcast show called the Virtually Speaking Podcast. This week I am a guest on their show, alongside Rich Peterson of FlashSoft. We spoke about VAIO, the new vSphere APIs for I/O Filters. While I described some basic features on VAIO, Rich describing the Cache Acceleration VAIO implementation for FlashSoft 4.0, created by the FlashSoft team over at SanDisk. This is the first fully certified VAIO implementation and I wrote an article about it last month that you can read here if you wish.…
I spent the last 10 days in the VMware HQ in Palo Alto, and had lots of really interesting conversations and meet-ups, as you might imagine. One of those conversations revolved around the minimum VSAN configurations. Let’s start with the basics. 2-node: There are two physical hosts for data and a witness appliance hosted elsewhere. Data is placed on the physical hosts, and the witness appliance holds the witness components only, never any data. 3-node: There are three physical hosts, and the data and witness components are distributed across all hosts. This configuration can support a number of failures to…
