Tutorial: Migration 101: From VMs to Kubernetes

on YouTube ↗01h 25m

" summary

Step‑by‑step migration that actually builds and runs: Dockerizing the API into a local image, loading it into kind load or pushing to Docker Hub, then applying Kubernetes YAML for Pod → Deployment → Service → Ingress (nginx) and swapping DNS (/etc/hosts) for a true no‑downtime migration without restarting the web tier. Adds logging with Fluentd → Elasticsearch → Kibana and metrics with Prometheus + Grafana, runs on a laptop but recommends ~16 GB RAM and 6 CPUs, and demonstrates a Consul service mesh adding mTLS and retries to mask a simulated 50% error rate.
