+Kubernetes has various types of probes:

+- [Liveness probe](#liveness-probe)

+Kubernetes 提供了多种探针：

+- [存活探针](#liveness-probe)
+- [就绪探针](#readiness-probe)
+- [启动探针](#startup-probe)

+<!--
+## Liveness probe
+
+Liveness probes determine when to restart a container. For example, liveness probes could catch a deadlock, when an application is running, but unable to make progress.
+-->
+## 存活探针   {#liveness-probe}
+
+存活探针决定何时重启容器。
+例如，当应用在运行但无法取得进展时，存活探针可以捕获这类死锁。
+
+<!--
+If a container fails its liveness probe repeatedly, the kubelet restarts the container.
+-->
+如果一个容器的存活探针失败多次，kubelet 将重启该容器。
+
+<!--
+Liveness probes do not wait for readiness probes to succeed. If you want to wait before
+executing a liveness probe you can either define `initialDelaySeconds`, or use a
+[startup probe](#startup-probe).
+-->
+存活探针不会等待就绪探针成功。
+如果你想在执行存活探针前等待，你可以定义 `initialDelaySeconds`，或者使用[启动探针](#startup-probe)。
+
+<!--
+## Readiness probe
+
+Readiness probes determine when a container is ready to start accepting traffic. This is useful when waiting for an application to perform time-consuming initial tasks, such as establishing network connections, loading files, and warming caches. 
+-->
+## 就绪探针   {#readiness-probe}
+
+就绪探针决定何时容器准备好开始接受流量。
+这种探针在等待应用执行耗时的初始任务时非常有用，例如建立网络连接、加载文件和预热缓存。
+
+<!--
+If the readiness probe returns a failed state, Kubernetes removes the pod from all matching service endpoints.
+
+Readiness probes runs on the container during its whole lifecycle.
+-->
+如果就绪探针返回的状态为失败，Kubernetes 会将该 Pod 从所有对应服务的端点中移除。
+
+就绪探针在容器的整个生命期内持续运行。
+
+<!--
+## Startup probe
+
+A startup probe verifies whether the application within a container is started. This can be used to adopt liveness checks on slow starting containers, avoiding them getting killed by the kubelet before they are up and running.
+-->
+## 启动探针   {#startup-probe}
+
+启动探针检查容器内的应用是否已启动。
+启动探针可以用于对慢启动容器进行存活性检测，避免它们在启动运行之前就被 kubelet 杀掉。
+
+<!--
+If such a probe is configured, it disables liveness and readiness checks until it succeeds.
+-->
+如果配置了这类探针，它会禁用存活检测和就绪检测，直到启动探针成功为止。
+
+<!--
+This type of probe is only executed at startup, unlike readiness probes, which are run periodically.

+这类探针仅在启动时执行，不像就绪探针那样周期性地运行。
