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 was doing some work in the lab with Storage Policy Based Management recently. I was using both vSAN and a Virtual Volume array from Nimble Storage. While I was able to create independent policies for both vSAN and VVols, I was curious to see if I could create a policy where I could be offered both datastore types for the initial placement of a VM. For example, if I wanted to ensure my VM was encrypted, could I have a policy which would be compliant with both vSAN datastore and the Virtual Volume datastore, so long as they both…
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…
In my last post, I showed some of the new command line functionality associated with deploying out a new Virtual Container Host (VCH) with vSphere Integrated Containers (VIC). I also highlighted how VIC now includes both Admiral for container orchestration via templates and the harbor registry is used for storing docker images. Harbor hosts docker images and Admiral hosts templates. An Admiral template describes how docker images hosted on Harbor gets instantiated (Kudos again to Massimo for this explanation). In my last post, I showed how I finally managed to deploy my VCH. Now the idea was that I should…
VMware recently release vSphere Integrated Containers v1.1. I got an opportunity recently to give it a whirl. While I’ve done quite a bit of work with VIC in the past, a number of things have changed, especially in the command line. What I’ve decided to do in the post is highlight some of the new command line options that are necessary to deploy the VCH, the Virtual Container Host. Once the VCH is deployed, at that point you have the docker API endpoint to start deploying your “containers as VMs”. Before diving into that however, I do want to clarify…
