VUM UMDS Docker Container for vSphere 6.5

by // Leave a Comment

Early last week, I had published an article on how to automate the deployment of VUM's Update Manager Download Service (UMDS) in vSphere 6.5 for an Ubuntu 14.04 distribution. The interesting backstory to that script is that it started from a Docker Container that I had initially built for the VUM UMDS. I found that being able to quickly spin up UMDS instance using a Docker Container purely from a testing standpoint was much easier than needing to deploy a full VM, especially as I have Docker running on my desktop machines. Obviously, there are limitations with using a Docker Container, especially if you plan to use UMDS for a longer duration and need persistence. However, for quick lab purposes, it may just fit the bill and even with Docker Containers, you can use Docker Volumes to help persist the downloaded content.

You can find the Dockerfile and its respective scripts on my Github repo here: https://github.com/lamw/vum-umds-docker

Below are the instructions on how to use the VUM UMDS Docker Container.

Automating the installation of VUM Update Manager Download Service (UMDS) for Linux in vSphere 6.5

by // 10 Comments

One of the most highly requested feature from customers with regards to the adoption of the vCenter Server Appliance (VCSA) is to have vSphere Update Manager (VUM) available as a Virtual Appliance. With the vSphere 6.5 release, this is now a reality as VUM is now embedded within the VCSA. The VUM service is also automatically enabled and associated with the vCenter Server instance which means from a customer standpoint, it is zero touch to get VUM up and running!

In addition to VUM being part of the VCSA 6.5, there is also the VUM Update Manager Download Service (UMDS) that can be installed on a separate Linux system. You can find the UMDS installer within the VCSA 6.5 ISO under the umds directory. To install UMDS, there are several pre-requisites that you must meet, some of which are documented here. The other requirements which are not documented are the additional OS package dependencies required to run the UMDS installer. While going through this by hand the first time, I found the following packages were required to install on an Ubuntu 14.04 distribution:

  • perl
  • tar
  • sed
  • psmisc
  • unixodbc
  • postgresql
  • postgresql-contrib
  • odbc-postgresql

For those of you who know me, if I have to perform something manually once, I might as well automate it for the future 🙂 I decided to create this quick shell script called install_umds65.sh which will allow you to easily deploy UMDS on an Ubuntu LTS 14.04 distribution. This can be useful for automated deployments or quickly standing up a lab environment.

Instant Clone community customization script repository

by // Leave a Comment

I am sure many of you are probably anxious to get your hands on the new VMFork aka Instant Clone PowerCLI Extensions Fling that was recently released! While using the Instant Clone cmdlets to help provide feedback and improvements, I have found that I spent the majority of my time on developing and fine-tuning the pre and post-customization scripts. Instead of having others hit similar issues that I ran into, I wanted to see how I could easily share some of the leanings but also incorporate collaboration?

After thinking about this for a bit, I realized this was a great opportunity to create a community Github repository of Instant Clone customization scripts that anyone can either use and/or contribute back to. I have already added a few OS customization scripts to the repo to start with like ESXi 6.0, Ubuntu 14.x and VMware Photon. To access the repository, simply visit https://github.com/lamw/vmfork-community-customization-scripts

The Instant Clone community customization script repository is broken up by series of OS directories which contain the relevent set of pre/post-customization scripts for that OS and any additional scripts that might be required. It may also contain further instructions on how to use the script as well as an example "driver" script which calls into the Instant Clone cmdlets demonstrating how to use the scripts.

Here is an example for ESXi 6.0 OS:

esxi60
├── post-esxi60.sh
├── pre-esxi60.sh
├── prep-esxi60.sh
└── vmfork-esxi60.ps1

For those that wish to contribute back, just fork the repository and send me a pull request. I am really looking forward to seeing what the community comes up with!
