调研方向
Start with packages/testcontainers/src/test-containers.ts and packages/testcontainers/src/testcontainers-runtime/strategies/utils/config.ts, then trace the listed process.env reads in the reaper, port forwarder, image name, generic container and auth paths. Define how configuration is resolved alongside environment variables and the properties file, including precedence and changes after runtime initialization. Done means TestContainers.configure() and getConfiguration() provide typed effective settings while existing configuration sources continue to work.

描述
What happens
Configuration comes only from environment variables and .testcontainers.properties, and each setting is read where it is used. Fourteen variables are read through process.env across packages/testcontainers/src (Ryuk image, port, privileged, verbose and disabled flags, the SSHD image and port, the hub image prefix, reuse, Docker auth config and others), plus the Docker host settings in the strategy config.
- Changing a setting from code means assigning to
process.envbefore the first container starts. - Nothing is typed or validated. A misspelt variable is silently ignored.
- There is no way to read the effective configuration.
Expected
A typed configuration object with one place that resolves it:
TestContainers.configure({
ryuk: { disabled: false, privileged: true },
hubImageNamePrefix: "registry.example.com/mirror",
reuse: { enabled: true },
});
- Environment variables and the properties file keep working, with a documented precedence.
TestContainers.getConfiguration()returns what is in effect.

Notes
- Java centralises this in
TestcontainersConfiguration. - Configuration must be set before the runtime client and Ryuk are created. Decide what happens when it is changed afterwards.
Dependencies
- Nothing blocks this. It can start now.
- Coordinate with #1568: the logger is a natural configuration setting.
