Kubernetes 1.6 – Taints and Tolerances for monitoring your cluster
June 26, 2017
At the office we use Datadog for monitoring our production systems, so when I spun up a test Kubernetes cluster (running Tectonic) I wanted to monitor using the same tool. Unfortunately the initial deploy of the Datadog agent didn’t work quite as well I was hoping. While I used their stock Kubernetes YAML as prescribed by the knowledgebase, it did not cover monitoring the Master nodes. Datadog support suggested I go another route (or host on docker based monitoring) which would have worked — but wasn’t as slick as I hoped. Fortunately just a few days ago I discovered the solution: Taints and Tolerances.
CoreOS Fest 2017
June 13, 2017
Just a bit over a week ago I had the opportunity to attend CoreOS Fest 2017 at the lovely Pier 27 in San Francisco. You might remember this same structure from my cruise posts as Pier 27 serves double duty as event center and cruise ship terminal. Now that I’ve had a chance to see both sides of the building, I definitely recommend the cruise terminal portion. Not that I didn’t greatly enjoy CoreOS Fest… but vacation always wins. Anyways, enough about the building, let’s talk about Kubernetes — because it was definitely the highlight of the conference. While I don’t think the Fest is bigger than Kubecon, it certainly was no slouch.
