From Kubernetes to a Self-Healing, Low-Cost Infrastructure

Short summary

Author migrated a background project from $150/month GKE to $40/month using Spot VMs with Stateful MIG, preserving auto-recovery capabilities. The setup uses Docker Compose both locally and on the VM for consistency, with Traefik replacing the managed ingress. Includes detailed breakdown of stateful disk attachment, automated bootstrap, and edge cases like preemption vs. scale-down.

• •Reduced infrastructure cost from $150 to $40/month by migrating from GKE to Spot VMs with Stateful MIG
• •Automated self-healing recovery on preemption with persistent storage and static IP attachment
• •Docker Compose provides local/remote consistency; Traefik replaces managed ingress with Let's Encrypt TLS
