Stateless Instances

To simply proxy requests to one of multiple instances of a container, you can use the getRandom function:

import { Container, getRandom } from "@cloudflare/containers";

const INSTANCE_COUNT = 3;

class Backend extends Container {
	defaultPort = 8080;
	sleepAfter = "2h";
}

export default {
	async fetch(request: Request, env: Env): Promise<Response> {
		const containerInstance = await getRandom(env.BACKEND, INSTANCE_COUNT);
		return containerInstance.fetch(request);
	},
};
