一、容器实例重启

容器重启的直接原因：云应用配置了健康检查，且健康检查存活探针失败，被集群自动重启。

详情请参考：云应用健康检查配置。健康检查配置示例：

检查延迟：容器启动后多少s开始进行健康检查。

检查间隔：健康检查开始后，按照固定间隔进行轮询，每隔xx秒检查一次。

超时时间：超过多少时间没有返回(http)或者没有正常退出(shell脚本)，则认为该次检查超时(失败)。

失败次数阈值：连续轮询多少次均失败后则认为健康检查失败，达到重启条件，集群对容器进行重启。

注：容器启动后，内部的应用进程也是刚启动，很可能没有启动完成，比如Java web还在启动Servlet、nodejs可能还在npm install，所以需要设置一定的检查延迟。

健康检查能在一定程度上维护应用稳定，比如容器中的Java进程因为OOM被内核kill，如果不设置健康检查，容器就不会重启。但是如果容器不重启，就会一直宕机着(也就是容器是存在着，但是里面的应用进程没有了)，无法对外提供服务。

那么，现在的问题是需要定位到健康检查失败的原因，这里只能提供一些常见源头的排查思路：

1）健康检查设置不合理，比如健康检查的延迟时间设置太短，服务还没有启动起来，健康检查就开始了，进而导致失败；比如健康检查超时时间设置太短，健康检查本身的执行如果有一定耗时，超过了设置的超时时间，也算失败，比如运行一段时间后，应用性能开始下降，导致健康检查也超时。

2）应用进程OOM，Java类型应用比较容器出现的(当然，PHP也有可能)。一般是由于容器规格和JVM进程的启动参数配置不够，可以适当进行优化。结合应用基础监控，观察内存使用趋势；可以为集群配置事件告警，当有OOM事件或者容器重启事件发生时，会有告警消息推送。

3）应用自身问题或下游服务异常，举个例子，云应用中访问RDS，如果RDS某个时刻性能特别差，云应用自身吞吐不够，整体huang住，新的请求均会失败，健康检查探针也会失败，进而导致容器重启。需要关注服务响应性能，建议接入ARMS应用监控(收费云产品)，可以对应用性能有直观的监控，同时特需要自行观察下游服务的监控信息。

4）宿主机docker daemon或者kubelet的一些内核异常，出现概率较小。这里也是推荐为集群配置事件告警，宿主机ECS出现一些问题时，能够及时感知。

二、容器实例驱逐

应用发布后，过了一段时间来看，实例的名称、IP、创建时间自己变了？

很可能是因为原Pod实例被驱逐，集群重新调度创建了新的实例。除开手动排空节点(将宿主机上的容器驱逐出本宿主机)，该现象一般是由于节点上某些资源使用达到了某个阈值，集群按照一定的调度策略，将节点上的一些Pod实例赶出去，然后由集群重新调度新的实例分配到其他节点。最常见的是磁盘，默认的docker容器运行在系统盘，当系统盘磁盘使用量超过90%时，节点上的实例会被驱逐。驱逐重新调度再启动的过程中，会对线上业务产生影响。

解决方案：

1）优化容器本身对磁盘等资源的占用、使用数据盘等，参考磁盘占用较大的原因。

2）为集群和应用配置事件告警，分别配置应用和集群(节点)维度的事件告警后，应用的Pod发生驱逐、节点资源不足(或者磁盘回收失败)等事件就能第一时间感知。比如类似的事件：

<span class="lake-preview-line" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"><span class="lake-preview-line-number lake-lm-pad-level-0" style="color: rgb(191, 191, 191); margin: 0px 8px 0px 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"></span><span class="lake-preview-codeblock-content" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">2020-07-21 10:24:43.000 [Event] Type: Warning, Reason: Evicted, Message: The node was low on resource: ephemeral-storage.

PS: 对于已经被驱逐的Pod，可以在“失败实例”中看到，建议手动清理，去过集群上被驱逐的失败Pod膨胀，会影响集群自身性能。

三、如何在容器中设置hosts

1）使用自定义镜像，在自定义镜像中dockerfile中指定自己需要的hosts，参考如下：

<span class="lake-preview-line" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"><span class="lake-preview-line-number lake-lm-pad-level-0" style="color: rgb(191, 191, 191); margin: 0px 8px 0px 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"></span><span class="lake-preview-codeblock-content" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">RUN echo "192.168.1.37 testgitlab.kuaidihelp.com"  >> /etc/hosts</span></span>

注，如果之前使用的是官方镜像，可以base官方镜像来制作你的自定义镜像，dockerfile可以这样写：

<span class="lake-preview-line" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"><span class="lake-preview-line-number lake-lm-pad-level-0" style="color: rgb(191, 191, 191); margin: 0px 8px 0px 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);"></span><span class="lake-preview-codeblock-content" style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">// 前缀registry.cn-zhangjiakou.aliyuncs.com不变，后面"jstopen/tomcat8:1.0.0"为使用的官方镜像
