Practical Top-down Resource Monitoring of a Kubernetes Cluster with Metrics Server
May 15, 2021 · 7 min read
You might have previously used observability tools such as Prometheus, Azure Monitor, AWS Container Insight, or commercial products such as Logic Monitor to monitor your Kubernetes cluster. Let’s probe the Kubernetes magic that makes the beautiful CPU and memory dials tick on the monitoring dashboards. Kubernetes has a built-in Metrics API (see spec.) and a simple CLI query, kubectl top (documentation), that you can use to fetch a snapshot of the CPU and memory consumption of a Kubernetes object.

Managing GitHub Organizations with GitHub GraphQL API
Feb 18, 2021 · 6 min read
I prefer using GraphQL over REST APIs wherever available, primarily because I can avoid overfetching and underfetching data while still enjoying the benefits of contract-based development. For this exercise, assume that you are the DevOps lead of an organization/open-source community that uses GitHub to manage its projects under a GitHub Organization. GitHub Organizations are shared accounts consisting of members and projects with sophisticated security and administrative features. You have been asked to ensure that your organization’s repositories are healthy such that there are no PRs in an unmerged state for more than one week, and every issue is either resolved or updated in 12 hours.

If you scroll to my website’s footer section, you will find GitHub and Netlify badges that display the status of the latest build and deployment. I use them to quickly check whether everything is fine with the world without navigating to their dashboards.

With KEDA (Kubernetes-based Event-Driven Autoscaling), you can host Azure Functions on Kubernetes. KEDA allows you to scale pods based on configurable rules that rely on metrics from data sources such as Azure Queue. The Microsoft documentation outlines how you can use the Prometheus scaler to scale HTTP triggered Azure functions. However, it does not discuss the the security of the transport channel in detail. This quick tip will demonstrate how you can expose your HTTP triggered Azure Functions over TLS/SSL (HTTPS endpoint).
