Docker Compose Validation Stacks#

Docker Compose validates multi-service architectures without Kubernetes overhead. It answers the question: do these services actually work together? Containers start, connect, and communicate – or they fail, giving you fast feedback before you push to a cluster.

This article provides complete Compose stacks for four common validation scenarios. Each includes the full docker-compose.yml, health check scripts, and teardown procedures. The pattern for using them is always the same: clone the template, customize for your services, bring it up, validate, capture results, bring it down.

Static Validation Patterns#

Static validation catches infrastructure errors before anything is deployed. No cluster needed, no cloud credentials needed, no cost incurred. These tools analyze configuration files – Helm charts, Kubernetes manifests, Terraform modules, Kustomize overlays – and report problems that would cause failures at deploy time.

Static validation does not replace integration testing. It cannot verify that a service starts successfully, that a pod can pull its image, or that a database accepts connections. What it catches are structural errors: malformed YAML, invalid API versions, missing required fields, policy violations, deprecated resources, and misconfigured values. In practice, this covers roughly 40% of infrastructure issues – the ones that are cheapest to find and cheapest to fix.
