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.
