Setting up an ODROID N2
I wanted a machine with more memory to be the master node for my ARM k3s cluster. I had an Odroid N2 with 4GB of RAM, sitting around, so here’s the log of getting it installed and running. ...
Backing Up the Cluster with Duplicacy
Motivation I wanted to ensure any data I put into my ARM k3s cluster is backed up to prevent data loss. I no longer recommend duplicacy. Instead, read my article on restic backups on TrueNas instead. ...
Growing EBS Volumes in Place
Yesterday I had to grow a live filesystem on a server in EC2, without downtime. I do this just infrequently enough to not quite remember all the details without poking around the internet, so I’m documenting it all in one place. ...
Trying K3s on ARM, Part 1
Why k3s and not stick with k8s? I wanted to experiment with k3s. They package everything you need in a single binary, don’t package in deprecated parts of k8s, and it works on Intel, ARMv7 and ARM64. It seemed like it’d be a less painful way to runn Kubernetes on my ARM cluster. ...

Get your money from the Equifax settlement regarding the 2017 security breach. ...
Adding a Distributed Filesystem to the Cluster
One of the reasons I set up my cluster was that I’m running out of space on my NAS. I don’t want to buy a whole new chassis, and while I could have put individual file shares on each cluster node, that would be both inconvenient and not provide any data redundancy without a lot of brittle home-rolled hacks to rsync data from node to node. And since distributed file systems are a thing, I’d rather not resort to hacks. ...
Things I Learned About Docker Mac
I had a bunch of cruft in start scripts that would determine the IP of my laptop and set it as an environment variable to pass to docker-compose and it turns out that with Docker for Mac you don’t have to do all that work - just use docker.for.mac.localhost as a hostname.
Fix macOS Captive WIFI Portal Issue
I’m not sure if this is just macOS Mojave being flaky or some interaction with the security malware installed on my work laptop, but it refuses to connect to some captive portals. ...
Parts list for the ARM cluster
I realized I forgot to include a parts list for the cluster in my ARM cluster post (all prices are as of March 3rd, 2019), so here we go. ...
Getting an ARM kubernetes cluster up and running
I recently decided to set up a Kubernetes cluster in my basement, partly because I’d never set a cluster up from scratch by myself, and partly because my existing NAS was beginning to run out of headroom. ...
