Question

我在docker-compose.yml之后使用容器：rc_db，rc_queue，rc_ui，rc_service； rc_ui取决于rc_db和rc_queue； rc_service取决于rc_queue。它们全部位于rc-network中。我已验证rc_db和rc_queue位于rc-network中，但是rc_ui和rc_service仍未附加@@。

似乎没有达到网络限制（即1024个容器？），所以我不知道为什么。

Answer 1

这与启动顺序无关。我认为设置环境变量的方式是错误的：

他们不应该是：

public function index()
{
    return view('adduser');
}

public function create_user(Request $request)
{
    return User::create(['input' => '$request->input']);
}

但是（（没有environment: - MONGO_HOST='rc_db' - MONGO_PORT=27017 - MONGO_ROOT_USERNAME='root' - MONGO_ROOT_PASSWORD='1234@5678' - AMQP_ADDRESS='rc_queue'，AMQP_ADDRESS在代码中使用URL地址，因此总是'错误）：

no route to host

Docker-compose不将容器连接到网络
