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.
Super slick logging with PapertrailApp

Let’s be honest, basic logging is not hard. Watching logs scroll by is just a tail away. Even shipping most logs to other hosts isn’t hard. However when you start adding these things together, throw in a dash of web interface, a sprinkle of filtering and a heavy dollop of integration… it gets to be a rather large “hack”. So why hack it when you can use a ready-made solution for next to no cost? That’s what I found in Papertrail.
