#### Instance Deployment
I started by logging into my Google Cloud account at https://console.cloud.google.com, and proceeded to create a new project (named `wireguard`) to keep my WireGuard-related resources together. I then navigated to **Compute Engine** and [created a new instance](https://console.cloud.google.com/compute/instancesAdd) inside that project. The basic setup is:

I click the circle-arrows icon at the right edge of the _Private key_ field, and that automatically generates this peer's private and public key pair. Simply clicking on the _Public key_ field will automatically copy the generated key to my clipboard, which will be useful for sharing it with the server. Otherwise I fill out the **Interface** section similarly to what I've done already:

`sshHost` is my new `win02` server that I'm going to connect to via SSH, and `sshUser` and `sshPass` should explain themselves. The `dnsServer` array will tell the script which DNS servers to try to create the record on; this will just be a single server in my lab, but I'm going to construct the script to support multiple servers in case one isn't reachable. And `supported domains` will be used to restrict where I'll be creating records; again, that's just a single domain in my lab, but I'm building this solution to account for the possibility where a VM might need to be deployed on a domain where I can't create a static record in this way so I want it to fail elegantly.

So this weekend I started exploring how I could do that for my [Hugo](https://gohugo.io) site[^site].
During my search, I came across a few different approaches using external services or additional scripts to run at build time, but I was hoping for a way to do this with Hugo's built-in tooling. I eventually came across a tremendously helpful post from Aaro titled [Generating OpenGraph images with Hugo](https://aarol.dev/posts/hugo-og-image/). This solution was exactly what I was after, as it uses Hugo's [image functions](https://gohugo.io/functions/images/filter/) to dynamically create a share image for each page.

This solution was exactly what I was after, as it uses Hugo's [image functions](https://gohugo.io/functions/images/filter/) to dynamically create a share image for each page.
I ended up borrowing heavily from Aaro's approach while adding a few small variations for my OpenGraph images.
- When sharing the home page, the image includes the site description.
- When sharing a post, the image includes the post title.
- ... but if the post has a thumbnail[^thumbnail] listed in the front matter, that gets overlaid in the corner.

[^thumbnail]: My current theme doesn't make use of the thumbnails, but a previous theme did so I've got a bunch of posts with thumbnails still assigned. And now I've got a use for them again!
Here's how I did it.
### New resources
Based on Aaro's suggestions, I used [GIMP](https://www.gimp.org/) to create a 1200x600 image for the base. I'm not a graphic designer[^web] so I kept it simple while trying to match the theme, font, and colors used on the site.

As I mentioned earlier, I wanted to have three slightly-different recipes for baking my OG images: one for the homepage, one for standard posts, and one for posts with an associated thumbnail. They all use the same basic code, though, so I wanted to be sure that my setup didn't repeat itself too much.

I'll need to use the Quartz64 serial console interface and ["Woodpecker" edition console USB adapter](https://pine64.com/product/serial-console-woodpecker-edition/) to interact with the board until I get ESXi installed and can connect to it with the web interface or SSH. The adapter comes with a short breakout cable, and I connect it thusly:

As a gentle reminder, Oracle's `iptables` configuration inserts a `REJECT all` rule at the bottom of each chain. I needed to make sure that each of my `ALLOW` rules get inserted above that point. So I used `iptables -L INPUT --line-numbers` to identify which line held the `REJECT` rule, and then used `iptables -I INPUT [LINE_NUMBER] -m state --state NEW -p [PROTOCOL] --dport [PORT] -j ACCEPT` to insert the new rules above that point.

#### Overview
My home network uses the generic `192.168.1.0/24` address space, with internet router providing DHCP addresses in the range `.100-.250`. I'm using the range `192.168.1.2-.99` for statically-configured IPs, particularly those within my lab environment. Here are the addresses being used by the lab so far:
| IP Address | Hostname | Purpose |
| ---- | ---- | ---- |
| `192.168.1.1` | | Gateway |
| `192.168.1.5` | `win01` | AD DC, DNS |
| IP Address | Hostname | Purpose |
|----------------|-----------|--------------------|
| `192.168.1.1` | | Gateway |
| `192.168.1.5` | `win01` | AD DC, DNS |

| `192.168.1.12` | `vcsa` | vCenter Server |
| `192.168.1.12` | `vcsa` | vCenter Server |
Of course, not everything that I'm going to deploy in the lab will need to be accessible from outside the lab environment. This goes for obvious things like the vMotion and vSAN networks of the nested ESXi hosts, but it will also be useful to have internal networks that can be used by VMs provisioned by vRA. So I'll be creating these networks:
| VLAN ID | Network | Purpose |
| ---- | ---- | ---- |
| 1610 | `172.16.10.0/24` | Management |
| 1620 | `172.16.20.0/24` | Servers-1 |

| 1698 | `172.16.98.0/24` | vSAN |
| 1699 | `172.16.99.0/24` | vMotion |
#### vSwitch1
I'll start by adding a second vSwitch to the physical host. It doesn't need a physical adapter assigned since this switch will be for internal traffic. I create two port groups: one tagged for the VLAN 1610 Management traffic, which will be useful for attaching VMs on the physical host to the internal network; and the second will use VLAN 4095 to pass all VLAN traffic to the nested ESXi hosts. And again, this vSwitch needs to have its security policy set to allow Promiscuous Mode and Forged Transmits. I also set the vSwitch to support an MTU of 9000 so I can use Jumbo Frames on the vMotion and vSAN networks.

Deploying the virtual appliances is just like any other "Deploy OVF Template" action. I placed the VMs on the `physical-cluster` compute resource, and selected to thin provision the VMDKs on the local datastore. I chose the "Isolated" VM network which uses VLAN 4095 to make all the internal VLANs available on a single portgroup.

Anyhoo, each of these VMs will need to be resolvable in DNS so I started by creating some A records:
|FQDN|IP|

| `vra.lab.bowdre.net` | `192.168.1.42` |
I then attached the installer ISO to my Windows VM and ran through the installation from there.

As a quick recap, I've got five networks available for vRA, split across my two sites using tags:
|Name |Subnet |Site |Tags |
| --- | --- | --- | --- |
| d1620-Servers-1 | 172.16.20.0/24 | BOW | `net:bow` |
| d1630-Servers-2 | 172.16.30.0/24 | BOW | `net:bow` |
| d1640-Servers-3 | 172.16.40.0/24 | BOW | `net:bow` |
| d1650-Servers-4 | 172.16.50.0/24 | DRE | `net:dre` |
| d1660-Servers-5 | 172.16.60.0/24 | DRE | `net:dre` |
| Name | Subnet | Site | Tags |
|-----------------|----------------|------|-----------|
| d1620-Servers-1 | 172.16.20.0/24 | BOW | `net:bow` |
| d1630-Servers-2 | 172.16.30.0/24 | BOW | `net:bow` |
| d1640-Servers-3 | 172.16.40.0/24 | BOW | `net:bow` |
| d1650-Servers-4 | 172.16.50.0/24 | DRE | `net:dre` |
| d1660-Servers-5 | 172.16.60.0/24 | DRE | `net:dre` |
I'm going to add additional tags to these networks to further define their purpose.
|Name |Purpose |Tags |
| --- | --- | --- |
| d1620-Servers-1 |Management | `net:bow`, `net:mgmt` |
| d1630-Servers-2 | Front-end | `net:bow`, `net:front` |
| d1640-Servers-3 | Back-end | `net:bow`, `net:back` |
| d1650-Servers-4 | Front-end | `net:dre`, `net:front` |
| d1660-Servers-5 | Back-end | `net:dre`, `net:back` |
| Name | Purpose | Tags |
|-----------------|------------|------------------------|
| d1620-Servers-1 | Management | `net:bow`, `net:mgmt` |
| d1630-Servers-2 | Front-end | `net:bow`, `net:front` |
| d1640-Servers-3 | Back-end | `net:bow`, `net:back` |
| d1650-Servers-4 | Front-end | `net:dre`, `net:front` |
| d1660-Servers-5 | Back-end | `net:dre`, `net:back` |
I *could* just use those tags to let users pick the appropriate network, but I've found that a lot of times users don't know why they're picking a certain network, they just know the IP range they need to use. So I'll take it a step further and add a giant tag to include the Site, Purpose, and Subnet, and this is what will ultimately be presented to the users:
|Name |Tags |
| --- | --- |
| d1620-Servers-1 | `net:bow`, `net:mgmt`, `net:bow-mgmt-172.16.20.0` |
| Name | Tags |

| d1640-Servers-3 | `net:bow`, `net:back`, `net:bow-back-172.16.40.0` |
