### Tek Load Balancer - Çoklu Worker Container { #one-load-balancer-multiple-worker-containers }

- kubeadm: ensured that a variety of API server requests were retried during "init", "join", "upgrade", "reset" workflows. Prior to this change, some API server requests, such as creating or updating ConfigMaps, were "one-shot" - i.e., they could fail if the API server dropped connectivity for a very short period of time.

/// tip | 提示

用于 HTTPS 的**TLS 终止代理**组件通常也会是**负载均衡器**。

///

使用容器时，你用来启动和管理容器的系统本身就已有内部工具，将来自该**负载均衡器**（也可能是**TLS 终止代理**）的**网络通信**（例如 HTTP 请求）传递到你的应用容器中。

### 一个负载均衡器 - 多个 worker 容器 { #one-load-balancer-multiple-worker-containers }

在 **Kubernetes** 等分布式容器管理系统中，使用其内部网络机制，允许在主**端口**上监听的单个**负载均衡器**将通信（请求）转发给可能**多个**运行你应用的容器。
