BUG | MCP can't find localStack container, expects a constant name

I've started working with localStack this week, after setting it up in a docker-compose file.
all the containers get a prefix name.

when I tried using the mcp, it couldn't find the running container.
after digging a bit and asking chat, it seems the issue is that the expected container name is hardcoded to be "localstack-main", and once I set the container name to that, the mcp had no issues.

file in question: src/lib/docker/docker.client.ts

  async findLocalStackContainer(): Promise<string> {
    const running = (await (this.docker.listContainers as any)({
      filters: { status: ["running"] },
    })) as Array<{ Id: string; Names?: string[] }>;

    const match = (running || []).find((c) =>
      (c.Names || []).some((n) => {
        const name = (n || "").startsWith("/") ? n.slice(1) : n;
        return name === "localstack-main";
      })
    );

    if (match) return match.Id as string;

    throw new Error("Could not find a running LocalStack container named 'localstack-main'.");
  }

this should be a configurable option.

Commencez dans src/lib/docker/docker.client.ts, au niveau de findLocalStackContainer, et suivez la manière dont le serveur MCP reçoit sa configuration. Remplacez l’attente fixe de localstack-main par un nom de conteneur configurable, tout en préservant la prise en charge des préfixes Docker Compose. C’est terminé lorsque le MCP peut trouver un conteneur LocalStack en cours d’exécution sans exiger exactement ce nom.
