containers

Four inspections before you delete a failing container: ps, logs, inspect, and port. Docker client 29.8.2 and Compose v5.5.1 on 11 October 2026.

EKS Kubernetes 1.36 is available with user namespaces GA and mutating admission policies. Since July 2026 you can roll back an in-place control-plane upgrade within 7 days at no extra charge — but only N→N-1, and Fargate or strict PDBs can block you.

AWS shipped ECS Express Mode on November 21, 2025 — three inputs (image + two IAM roles) and Express Mode provisions Fargate, ALB, HTTPS, auto scaling, and a *.ecs.*.on.aws URL. Up to 25 services can share one ALB. No Express Mode surcharge.

ECR storage is $0.10/GB-month — twice S3 Standard. Cross-region replication doubles or triples that. Enhanced scanning bills $0.09 per image scanned, on every push. Pull-through caches for Docker Hub and ECR Public add storage plus data-transfer-in. A 200-service organization with 10 environments and 3 regions can spend more on ECR than on the EKS clusters pulling from it.

Pick runtimes by ECS density and team skills — not synthetic RPS. July 2026: FrankenPHP worker vs PHP-FPM, Node, Go memory bands + density matrix.

A deep technical guide to running PHP, Python, and Node.js applications on Amazon ECS in production — covering Fargate vs EC2, FrankenPHP vs Nginx+FPM, multi-container task patterns, zero-downtime deployments, and observability.

ECS is "AWS-native containers." EKS is "Kubernetes, but you're still on the hook for everything Kubernetes." A decision guide for picking between ECS and EKS based on team Kubernetes experience, operational complexity, and the cost gap at production scale.
