Workaround to deploy vSphere Integrated Containers 1.1 OVA using PowerCLI (SHA256 not supported)

06.19.2017 by William Lam // 2 Comments

Last week I had noticed several folks were having issues deploying the latest vSphere Integrated Containers (vIC) 1.1 OVA using PowerCLI. The following error message was observed when using the Get-OvfConfiguration cmdlet which is needed before importing an OVF/OVA:

PowerCLI doesn't support SHA256 hash codes in OVF manifest

As you probably have guessed, the issue is that PowerCLI currently does not support the SHA256 hashing algorithm, which the latest vIC OVA was generated with. I suspect this is probably related to the change with OVFTool 4.2 which now defaults to SHA256 which also has some implications on which vSphere UI you can use to import OVF/OVAs which I had written about here. As of today, PowerCLI currently only supports SHA1 and anything greater will not work. I have already reported this to Jake Robinson who is the PM for PowerCLI and hopefully this will get addressed in a future update.

In the meantime, you can deploy vIC using either the vSphere Web Client and/or ESXi Embedded Host Client, both support SHA256. If you wish to Automate the deployment of vIC, the only option right now is to convert the OVA from SHA256 to SHA1. You can easily do this by using OVFTool which is available on all OS platforms. If you already have downloaded the vCenter Server Appliance (VCSA) ISO, you can even make use of its bundled OVFTool in case you did not want to install OVFTool (You can find it under vcsa/ovftool in extracted ISO).

To convert the hashing algorithm, we just need to pass in our desire hash to the --shaAlgorithm parameter.

ovftool.exe --shaAlgorithm=SHA1 C:\Users\primp\Desktop\vic-v1.1.1_56a309fb.ova C:\Users\primp\Desktop\vic-v1.1.1_56a309fb-SHA1.ova

Once the conversion is done, you can delete the original vIC OVA and then use PowerCLI to import the new OVA just like you would with any other OVF/OVA!

Test driving ContainerX on VMware vSphere

06.20.2016 by William Lam // 2 Comments

Over the weekend I was catching up on some of my internet readings, one of which is Timo Sugliani's excellent weekly Tech Links (highly recommend a follow). In one of his non-VMware related links (which funny enough is related to VMware), I noticed that the recent Container startup ContainerX has just made available a free version of their software for non-production use. Given part of the company's DNA included VMware, I was curious to learn more about their solution and how it works, especially as it relates to VMware vSphere which is one of the platforms it supports.

For those not familiar with ContainerX, it is described as the following:

ContainerX offers a single pane of glass for all your containers. Whether you are running on Bare Metal or VM, Linux or Windows, Private or Public cloud, you can view your entire infrastructure in one simple management console.

In this article, I will walk you through in how to deploy, configure and start using ContainerX in a vSphere environment. Although there is an installation guide included with the installer, I personally found the document to be a little difficult to follow, especially for someone who was only interested in a pure vSphere environment. The mention of bare-metal at the beginning was confusing as I was not sure what the actual requirements were and I think it would have been nice to just have a section that covered each platform from start to end.
