Container Images

Dockerfiles live here (one folder per target runtime) instead of inline string literals in code, so they get proper syntax highlighting, linting, and diffs.

Who uses what?

File	Used by	Build context	Inputs it expects
docker/quarkus/Dockerfile	docker-compose.yml (service confapi)	repo root	full source tree (does its own mvn package)
docker/quarkus/Dockerfile.dev	docker-compose.yml (service confapi-dev, profile dev)	repo root	source bind-mounted at runtime (runs mvn quarkus:dev)
docker/quarkus/Dockerfile.it	ConfApiContainer (IT tests)	a temp dir assembled by Testcontainers	target/quarkus-app/
docker/liberty/Dockerfile.it	ConfApiContainer (-Druntime.profile=liberty)	temp dir	target/confapi.war + src/main/liberty/config/server.xml
docker/helidon/Dockerfile.it	ConfApiContainer (-Druntime.profile=helidon)	temp dir	target/confapi.jar
