Monitoring & Scaling Laravel on Kubernetes

In this episode, we'll take a look at auto-scaling our Laravel application based on metrics.
Please be aware, we couldn't find a working Prometheus library for Laravel that worked. We did successfully get external request metrics with Linkerd sidecar, but not custom metrics instrumented in PHP.

Kubernetes

Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, that facilitates both declarative configuration and automation. It has a large, rapidly growing ecosystem. Kubernetes services, support, and tools are widely
available.
The name Kubernetes originates from Greek, meaning helmsman or pilot. Google open-sourced the Kubernetes project in 2014. Kubernetes combines over 15 years of Google's experience running production workloads at scale with best-of-breed ideas and practices from the community.
Designed on the same principles that allows Google to run billions of containers a week, Kubernetes can scale without increasing your ops team.
Whether testing locally or running a global enterprise, Kubernetes flexibility grows with you to deliver your applications consistently and easily no matter how complex your need is.
Kubernetes is open source giving you the freedom to take advantage of on-premises, hybrid, or public cloud infrastructure, letting you effortlessly move workloads to where it matters to you.
