From Docker Build to Kubernetes Deploy on Ubuntu: The Image Workflow That Never Changed

From Docker Build to Kubernetes Deploy on Ubuntu: The Image Workflow That Never Changed

Short summary

A practical end-to-end guide for building Docker images and deploying them to Kubernetes on Ubuntu. Covers multi-stage builds with distroless images, multi-arch builds with buildx, immutable tagging, Kubernetes deployment manifests with readiness/liveness probes, image pull secrets, and rollback workflows. The core message: Docker as build tool and Kubernetes as runtime never changed despite dockershim drama.

  • •Multi-stage Docker builds with distroless images minimize attack surface on Kubernetes
  • •Immutable tags and readiness probes prevent rollback failures and intermittent 502s
  • •Docker build + Kubernetes runtime workflow remains unchanged despite dockershim removal

Generated with AI, which can make mistakes.
