Quick Salt State to Deploy Netdata

As a follow-up to my recent explorations with using Tailscale Serve to make netdata monitoring readily available on my tailnet, I wanted a quick way to reproduce that configuration across my handful of systems. These systems already have Tailscale installed and configured, and they're all managed with Salt. So here's a hasty Salt state that I used to make it happen. It simply installs netdata using the handy-dandy kickstart script, and then configures Tailscale to Serve the netdata instance (with a trusted cert!

Download Web Folder Contents with Powershell (wget -r replacement)

We've been working lately to use HashiCorp Packer to standardize and automate our VM template builds, and we found a need to pull in all of the contents of a specific directory on an internal web server. This would be pretty simple for Linux systems using wget -r, but we needed to find another solution for our Windows builds. A coworker and I cobbled together a quick PowerShell solution which will download the files within a specified web URL to a designated directory (without recreating the nested folder structure):

Bulk Import vSphere dvPortGroups to phpIPAM

I recently wrote about getting started with VMware's Tanzu Community Edition and deploying phpIPAM as my first real-world Kubernetes workload. Well I've spent much of my time since then working on a script which would help to populate my phpIPAM instance with a list of networks to monitor. Planning and Exporting The first step in making this work was to figure out which networks I wanted to import. We've got hundreds of different networks in use across our production vSphere environments.

Using PowerCLI to list Linux VMs and Datacenter Locations

I recently needed to export a list of all the Linux VMs in a rather large vSphere environment spanning multiple vCenters (and the entire globe), and I wanted to include information about which virtual datacenter each VM lived in to make it easier to map VMs to their physical location. I've got a Connect-vCenters function that I use to quickly log into multiple vCenters at once. That then enables me to run a single query across the entire landscape - but what query?

Automatic unattended expansion of Linux root LVM volume to fill disk

While working on my vRealize Automation 8 project, I wanted to let users specify how large a VM's system drive should be and have vRA apply that without any further user intervention. For instance, if the template has a 60GB C: drive and the user specifies that they want it to be 80GB, vRA will embiggen the new VM's VMDK to 80GB and then expand the guest file system to fill up the new free space.

Using PowerShell and a Scheduled Task to apply Windows Updates

In the same vein as my script to automagically resize a Linux LVM volume to use up free space on a disk, I wanted a way to automatically apply Windows updates for servers deployed by my vRealize Automation environment. I'm only really concerned with Windows Server 2019, which includes the built-in Windows Update Provider PowerShell module. So this could be as simple as Install-WUUpdates -Updates (Start-WUScan) to scan for and install any available updates.

Auto-connect to ProtonVPN on untrusted WiFi with Tasker [Update!]

[Update 2021-03-12] This solution recently stopped working for me. While looking for a fix, I found that OpenVPN had published some notes on controlling the official OpenVPN Connect app from Tasker. Jump to the Update below to learn how I adapted my setup with this new knowledge. I recently shared how I use Tasker and Home Assistant to keep my phone from charging past 80%. Today, I'm going to share the setup I use to automatically connect my phone to a VPN on networks I don't control.

Safeguard your Android's battery with Tasker + Home Assistant

A few months ago, I started using the AccuBattery app to keep a closer eye on how I'd been charging my phones. The app has a handy feature that notifies you once the battery level reaches a certain threshold so you can pull the phone off the charger and extend the lithium battery's service life, and it even offers an estimate for what that impact might be. For instance, right now the app indicates that charging my Pixel 5 from 51% to 100% would cause 0.

Logging in to Multiple vCenter Servers at Once with PowerCLI

I manage a large VMware environment spanning several individual vCenters, and I often need to run PowerCLI queries across the entire environment. I waste valuable seconds running Connect-ViServer and logging in for each and every vCenter I need to talk to. Wouldn't it be great if I could just log into all of them at once? I can, and here's how I do it. The Script The following Powershell script will let you define a list of vCenters to be accessed, securely store your credentials for each vCenter, log in to every vCenter with a single command, and also close the connections when they're no longer needed.
