Adding better monitoring for applications running in my k8s cluster using Prometheus.


10 minute read

It’s been a while since I learned of the wonders (and cleared up my misconceptions) of dedicated hosting and set up a “Baremetal” CoreOS single-node k8s cluster. For a while now I’ve maintained a single large (by my standards) machine that has been running Kubernetes, and purring right along – outside of the occasional restart or operator error, it hasn’t gone down and has kept my applications running.

I recently ran into a bit of trouble using JSPM from the Gitlab CI build for one of my projects – in particular, I’ve started separating my shared frontend UI code (projects like vue-component-library, a small collection of homegrown, badly designed UI components), and reusing across projects.

Turns out jetstack/kube-lego is pretty simple and *just works* which is amazing, props to the team over at jetstack and as always the kubernetes team, for making this more intelligent automation possible.
