Java 具有--restart=内存不足错误后始终不重新启动的Docker容器

正如您所看到的，bellow my restart police设置为“always”，但几乎每晚我都会收到一个内存不足的消息（这是意料之中的，而不是我试图解决的问题），早上容器就会停止。 如果我们检查restarcount属性，它显示2，这是否意味着它重新启动两次，然后停止？是否有可能在启动过程中由于某种原因失败并停止尝试？ 当我再次手动启动时，一切正常

这是docker检查的结果，如果你对发生的事情有线索，请告诉我

我相信如果容器在10秒内出现故障，Docker将不会重新启动。嗯，谢谢你，我不知道。如果是这种情况，应该有一个选项来延迟重启X秒，否则在这种情况下它看起来无法正常工作。每天早上我都会做docker start xxx，它的启动很好。它会不会很脆弱，只是偶尔会失败？也许可以添加一些日志来确定偶尔出现故障的根本原因？我相信如果容器在10秒内出现故障，Docker将不会重新启动。嗯，谢谢你，我不知道。如果是这种情况，应该有一个选项来延迟重启X秒，否则在这种情况下它看起来无法正常工作。每天早上我都会做docker start xxx，它的启动很好。它会不会很脆弱，只是偶尔会失败？也许可以添加一些日志来确定偶然故障的根本原因？
