Upcoming VMUG Conferences

Speaking to customers and public speaking is something I have come to really enjoy the past few years. The opportunity to share experiences, issues and resolutions really resonates with me, so I am grateful I have had opportunity to present in several VMUG webinars the past two years. Now I have the opportunity to speak, in-person, at two upcoming VMUG conferences — Phoenix, AZ in June and Indianapolis, IN in July.

I will be speaking on vSphere 6.7, including NSX, and how the VMware internal private cloud team leverages the SDDC to provide a variety of workload capacities to the internal R&D teams. I will be covering best practices and lessons learned for the SDDC stack with 6.7 and how to upgrade successfully to the latest releases from vSphere 6.0 and vSphere 6.5

CoreOS Fest 2017 Synopsis

I had the opportunity to attend the CoreOS Fest 2017 in San Francisco for a day this past week. There are lots of exciting things happening in the cloud native space, and CoreOS, with its heavy influence with Kubernetes is at the forefront of much of the innovation. The conference itself was on the smaller side, but the amount of emerging technology focused sessions was impressive — I will be excited to see how it grows over the coming years. While there, I was able to attend the session by one of Adobe’s Principle Architects — Frans van Rooyen. (Frans and I worked together from 2012 – 2014 at Adobe.)

In his session, he spoke about several fundamental architecture principles and how they have been applied in the new multi-cloud initiative at Adobe. The platform they have built over the past two years is capable of being deployed inside a data center, inside AWS, inside Azure and even locally on a developers laptop — while providing the same experience to the developer or operations engineer.

The platform is based on CoreOS and uses the Ignition project to provide the same level of provisioning regardless of which cloud platform the workload is deployed on. I hadn’t heard of Ignition or how it operated to provide the level of provisioning it does and will be a technology I investigate further into now. If you are interested in learning more, I encourage you to reach out to Frans over Twitter.

Frans has also spoken about the multi-cloud platform at Mesoscon, focusing on the inclusion of Apache Mesos — the session can be watched on YouTube.



Install VMware Integrated OpenStack on VCF

I am currently pursuing my VCDX certification and the design I have submitted is based on VMware Cloud Foundation and VMware Integrated OpenStack. As part of the required documentation, I included a deployment guide — unfortunately, it is not as simple as laying down the SDDC components and the VIO vApp for the deployment.

This blog post will cover a couple items that are needed to get the two pieces playing together.

Shared Edge & Workload Cluster

The VCF architecture currently has a limitation that a vCenter Server can only have a single vSphere cluster — it’s a 1:1 relationship. VMware Integrated OpenStack requires either 3 clusters in a single vCenter Server or a management cluster in one vCenter Server instance and two clusters in a second vCenter Server. Neither of these options are compatible with VMware Integrated OpenStack.

In order to make it work, we are going to use a two vCenter Server deployment of VMware Integrated OpenStack and modify the OMS server to combine the NSX Edge and Workload Clusters into one. We do this by editing a single configuration file and restarting the oms service running on the VIO vApp Management (OMS) VM.

$ cd /opt/vmware/vio/etc
$ sudo vim moms.properties

Add the following line to the end of the file:
oms.allow_shared_edge_cluster = true

$ sudo restart oms

VMware Integrated OpenStack can now be deployed on top of VMware Cloud Foundation.

VXLAN-backed External Network

This one is a bit trickier and is an obstacle whether or not you are using VMware Cloud Foundation as the infrastructure layer.

Logically, the end result for the OpenStack external network is to attach to a VXLAN port group created by NSX. The NSX logical switch network is attached to the internal interface on a NSX Distributed Logical Router.

The following is the logical diagram for the architecture.

external openstack

The issue is that during the deployment of an OpenStack instance using VMware Integrated OpenStack, you have to specify an external network. However, VMware Integrated OpenStack will not allow a vSphere Administrator to select a VXLAN port group during the deployment. I got around this by creating a non-VXLAN port group on the DVS used only for the deployment.

Once the OpenStack deployment is complete, I needed to attach the actual VXLAN-backed port group as the external network.

SSH to the OMS server
$ ssh -l viouser oms.domain.local

SSH to an OpenStack controller VM
$ ssh controller01
$ sudo cp /root/cloudadmin_v3.rc .
$ source cloudadmin_v3.rc
$ neutron

(neutron) net-list
(neutron) net-create --provider:network_type=portgroup --provider:physical_network=virtualwire-XX vio-external-network
(neutron) net-list

The network will now appear in the OpenStack network list. Go ahead and create your subnet for the external IP addresses, based on the network assignment in your environment.

If you have questions or issues with implementing these changes in your environment, please reach out.

vDM30in30 Wrap-up


The vDM30in30 challenge is complete! It was an amazing challenge to post almost every single day over the course of the month of November. I feel good about the quality of posts I put out, especially some of the VCDX related posts.

I found that I posted about OpenStack and VMware NSX far more than I had initially intended. I also did not have any posts related to Photon Platform, Mesosphere or Docker, which is a bit disappointing. However, I learned that most of the posts came from what I was involved in at work during the day.

There are a few outstanding topics I still want to write out before the end of the year, including:

  • VMware Integrated Containers
  • Network Link-State Tracking
  • NSX ECMP Edges with OSPF Dynamic Routing

Having worked at Adobe in the Digital Marketing business unit previously, I’ve learned how important analytics are. Looking at the analytics for the month, I drove visits and read posts significantly for the site over the month. The top 5 posts over the course of the month were:

  1. IGMP, Multicast and learning a lesson – 128 views
  2. Multi-tenant OpenStack with NSX – Part 1 – 91 views
  3. NSX DLR Designated Instance – 89 views
  4. OpenStack Alert Definitions in vRealize Operations – 83 views
  5. VMware Storage I/O Control (SIOC) Overview – 78 views

Well, until next year. Enjoy.

VMware has a lot of products that compose the SDDC stack. Out of all of them — after the foundational ESXi — vRealize Log Insight had become my absolute favorite product. It is one of the first things I deploy inside any new environment, as soon as vCenter Server is online and sometimes before. It’s ability to parse, collect and search log messages throughout the stack, while providing easy-to-use dashboards make it so much more powerful than some of its competitors.

Steve Flanders blogs about several VMware-related topics, and the Log Insight posts are the highlight of his site. Oftentimes his site is my first stop when I have a question — even before the documentation.

Steve has a quick reference for his Log Insight posts, which can be found here.

The power of Log Insight can easily be realized within any environment and becomes even more powerful with the installation of the Content Packs. Content Packs can be downloaded through the UI interface directly and include components for both VMware products and industry products.

Some of the Content Packs I find myself relying on include:

  • VMware NSX
  • OpenStack
  • Synology (for the home lab users out there)
  • Nginx
  • vRealize Operations

There are dozens more and it is possible to even write your own content packs. The VMware Developer Center provides information on how to do so.

If you are thinking about using Log Insight or just looking for new information to learn how to better utilize it in your environment, I highly encourage you head over to SFlanders.net and check out all the resources there. Also give Steve a follow over on Twitter.
