Docker 命令挂在容器上

Question

我使用 msql-server:5.7 创建了一个容器。创建后，我可以毫无问题地访问它。但是几分钟后，容器中的所有 Docker 命令都没有响应。我无法检查、停止或杀死。有什么办法可以调试吗？我还有一些其他容器运行，但这些都可以。

$ docker ps -a

Answer 1

您确定这不是 docker 特定问题吗？也许不支持的内核版本？所有日志都转储到 /var/lib/docker/volumes 目录中卷内的日志文件。尝试运行不带 -d 标志的容器，以便所有输出直接转到 stdout 以确定问题。

Answer 2

经过几天的尝试，我将实例类型从 m4.2xlarge 更改为 m4.4xlarge。并在尝试 1 天后。看来问题解决了。我不知道为什么，但到目前为止还不错
