Spring Cloud Config ​

A Spring Cloud Config Server container, ready-checked via its actuator health endpoint.

Default image: hyness/spring-cloud-config-server:latestExposed port: 8888Wait strategy: Wait.forHttp("/actuator/health").forPort(8888)Memory: withMemoryLimit(1024) by default

MemberReturns
SpringCloudConfigContainer.start(image?)Promise<SpringCloudConfigContainer> — boots the container
.uriThe config server's base URL

Example ​

ts
import { SpringCloudConfigContainer } from "rightsize/modules";

await using config = await SpringCloudConfigContainer.start();
console.log(await (await fetch(`${config.uri}/actuator/health`)).json());

Backend notes ​

Compatibility check: the constructor only accepts images whose repository is hyness/spring-cloud-config-server (registry host, tag, and digest stripped). A different repository throws IncompatibleImageError before any backend call; override with DockerImageName.parse(image).asCompatibleSubstituteFor("hyness/spring-cloud-config-server") for a verified compatible fork or mirror.

The 1024MB memory floor is required on microsandbox, not optional. Paketo's memory calculator sizes this JVM image's fixed regions (measured around 705MB) above microsandbox's default microVM RAM (~450MB) — without withMemoryLimit(1024), the container never becomes ready on microsandbox (times out around 180s); with it, boot completes in roughly 19s. This is set by the module by default; you don't need to configure it, and it's harmless on Docker.
