Dear reader, if you are like me, you may only be getting to grips with containers and how they compare to the virtual machine approach of running applications. While there has been a lot of buzz around containers, I’ve heard some rumblings around Unikernels, but to be honest, haven’t really been paying too much attention to them. That was until my recent visit to Norway, where I was speaking at the Oslo VMUG. One of the sessions delivered at that VMUG was by Per Buer who is CEO of a company called IncludeOS. IncludeOS are one of a handful of…
This is a bit of a long post, but there is a lot to cover. In a previous post, I walked through the deployment of Photon Platform v1.2, which included the Photon Installer, followed by the Photon Controller, Load-Balancer and Lightwave appliances. If you’ve read the previous post, you will have read that Photon Platform v1.2 include the OVAs for these components within the Photon Installer appliance. So no additional download steps are necessary. However, because vSAN is not included, it will have to be downloaded separately from MyVMware. The other very important point is that Photon Platform is not…
The folks over at Infinio were kind enough to send me their latest Cache Accelerator I/O Filter so I could set it up in my lab. I must say, this seemed to be the most intuitive of the VAIO plugins (vSphere API for I/O Filters) that I have used to date. In this post, I just want to run run through the deployment of the filter, as opposed to looking at any of the potential performance benefits. If you want an overview of VAIO, have a read of the write-up that I did from VMworld 2014 here. I’ve also looked…
In this post, I wanted to play a little more with our registry product (Harbor) and how it integrated with vSphere Integrated Containers (VIC). The workflow that I am going to show you in this post is using Docker on MAC to pull an image from the docker hub, do whatever I need to do with that image/application, and then push out the updated version to my private Harbor registry. From my Harbor registry I am then going to pull that image down and run it on my production VCH (Virtual Container Host). The VCH provides my docker API endpoint…
I’ve been getting back into doing a bit of testing with vSphere Integrated Containers 1.1 (VIC for short) in my lab. One of the things that I am very interested in revisiting is how to do persistence of data with VIC and “Containers as VMs”. I did some work on this in the past, but a lot has changed since I last looked at it (which was VIC v0.4.0). In this post, we’ll download a nginx web server image and start it up. We’ll look at how you can make changes to the web server while it is running, but…
A very short post simply to bring an issue to your attention which a number of folks have pinged me about this week. With vSAN 6.6, there is a new feature called Configuration Assistant. As the name implies, it tries to highlight possible configuration issues with your vSAN infrastructure. A number of these checks are related to network configuration. Configuration Assistant checks to make sure that the vSAN network has availability by verifying that there are 2 or more physical NICs. For example, let me show you my setup. Here is my vSAN vmkernel port, and as you can see,…
I was looking into some behavior recently to assist one of our partners. He described a situation that they observed during proof-of-concept testing. I thought it would be of benefit to highlight this behavior in case you also observe it, and you are curious as to why it is happening. Let’s begin with a description of the test. The customer has a 7-node vSAN, and has implemented RAID-6 erasure coding for all VMs across the board. The customer isolated one host, and as expected, the VMs continued to run without issue. The customer was also able to clones virtual machine…
