Now that I've got everything in order I can start the install. A lot of experimentation on my part confirmed the sad news about the USB ports: of the four USB ports, only the top-right USB2 port works reliably for me. So I connect my ~~USB NIC+hub to that port, and plug in my 256GB drive to the hub~~[^v1.10] 256GB USB drive there. This isn't ideal from a performance aspect, of course, but slow storage is more useful than no storage.

On that note, remember what I mentioned earlier about how the ESXi installer would want to fill up ~128GB worth of whatever drive it targets? The ESXi ARM instructions say that you can get around that by passing the `autoPartitionOSDataSize` advanced option to the installer by pressing `[Shift] + O` in the ESXi bootloader, but the Quartz64-specific instructions say that you can't do that with this board since only the serial console is available... It turns out this is a (happy) lie.

|

I hooked up a monitor to the board's HDMI port and a USB keyboard to a free port on the hub and verified that the keyboard let me maneuver through the BIOS menu. From here, I hit the **Reset** button on the Quartz64 to restart it and let it boot from the connected USB drive. When I got to the ESXi pre-boot countdown screen, I pressed `[Shift] + O` as instructed and added `autoPartitionOSDataSize=8192` to the boot options. This limits the size of the new-for-ESXi7 ESX-OSData VMFS-L volume to 8GB and will give me much more space for the local datastore.

I've [written in the past](/3d-modeling-and-printing-on-chrome-os) about the Linux setup I've been using on my Pixel Slate. My Slate's keyboard stopped working over the weekend, though, and there don't seem to be any replacements (either Google or Brydge) to be found. And then I saw that [Walmart had the 64GB Lenovo Chromebook Duet temporarily marked down](https://twitter.com/johndotbowdre/status/1320733614426988544) to a mere $200 - just slightly more than the Slate's *keyboard* originally cost. So I jumped on that deal, and the little Chromeblet showed up today.

### A real workload - phpIPAM
|
||||
Demos are all well and good, but how about a real-world deployment to tie it all together? I've been using a [phpIPAM instance for assigning static IP addresses for my vRealize Automation deployments](/integrating-phpipam-with-vrealize-automation-8/), but have *only* been using it to monitor IP usage within the network ranges to which vRA will provision machines. I recently decided that I'd like to expand phpIPAM's scope so it can keep an eye on *all* the network ranges within the environment. That's not a big ask in [my little self-contained homelab](/vmware-home-lab-on-intel-nuc-9/), but having a single system scanning all the ranges of a large production network probably wouldn't scale too well.
|
||||
|
||||
Fortunately the phpIPAM project provides a [remote scanning agent](https://github.com/phpipam/phpipam-agent) which can be used for keeping an eye on networks and reporting back to the main phpIPAM server. With this, I could deploy an agent to each region (or multiple agents to a region!) and divide up the network into chunks that each agent would be responsible for scanning. But that's a pretty lightweight task for a single server to manage, and who wants to deal with configuring multiple instances of the same thing? Not this guy.

But that's a pretty lightweight task for a single server to manage, and who wants to deal with configuring multiple instances of the same thing? Not this guy.
|
||||
|
||||
So I set to work exploring some containerization options, and I found [phpipam-docker](https://github.com/phpipam-docker/phpipam-docker). That would easily replicate my existing setup in a trio of containers (one for the web front-end, one for the database back-end, and one with `cron` jobs to run scans at regular intervals)... but doesn't provide a remote scan capability. I also found a [dockerized phpipam-agent](https://github.com/pierrecdn/phpipam-agent), but this one didn't quite meet my needs. It did provide me a base to work off of though so a few days of [tinkering](https://github.com/jbowdre/phpipam-agent-docker) resulted in me publishing my first [Docker image](https://github.com/jbowdre/phpipam-agent-docker/pkgs/container/phpipam-agent). I've still some work to do before this application stack is fully ready for production but it's at a point where I think it's worth doing a test deploy.

### Conclusion
|
||||
I still need to do more work to the containerized phpIPAM stack ready for production, but I'm feeling pretty good for having deployed a functional demo of it at this point! And working on this was a nice excuse to get a bit more familiar with Tanzu Community Edition specifically, Kubernetes in general, and Docker (I learned a ton while assembling the `phpipam-agent` image!). I find I always learn more about a new-to-me technology when I have an actual project to do rather than just going through the motions of a lab exercise. Maybe my notes will be useful to you, too.
