#### Prometheus und andere Gründe

Sie könnten auch **andere Gründe** haben, die es einfacher machen würden, einen **einzelnen Container** mit **mehreren Prozessen** zu haben, anstatt **mehrere Container** mit **einem einzelnen Prozess** in jedem von ihnen.

 `http_response_size_bytes_sum`

 due to removal from the prometheus client library. Prometheus http request meta-metrics are now generated from [`promhttp.InstrumentMetricHandler`](https://godoc.org/github.com/prometheus/client_golang/prometheus/promhttp#InstrumentMetricHandler) instead.
- Following metrics from kube-controller-manager are now marked as with the ALPHA stability level:

#### Prometheus и прочие причины

У вас могут быть и **другие причины**, когда использование **множества процессов** внутри **одного контейнера** будет проще, нежели запуск **нескольких контейнеров** с **единственным процессом** в каждом из них.

### Sync/Async Replication

By default, replication is completed asynchronously. If synchronous replication is desired, set the --sync flag while adding a

#### Prometheus和其他原因

你还可能有**其他原因**，这将使你更容易拥有一个带有**多个进程**的**单个容器**，而不是拥有每个容器中都有**单个进程**的**多个容器**。

例如（取决于你的设置）你可以在同一个容器中拥有一些工具，例如 Prometheus exporter，该工具应该有权访问**每个请求**。

在这种情况下，如果你有**多个容器**，默认情况下，当 Prometheus 来**读取metrics**时，它每次都会获取**单个容器**的metrics（对于处理该特定请求的容器），而不是获取所有复制容器的**累积metrics**。

在这种情况， 这种做法会更加简单：让**一个容器**具有**多个进程**，并在同一个容器上使用本地工具（例如 Prometheus exporter）收集所有内部进程的 Prometheus 指标并公开单个容器上的这些指标。
