Docker：容器继续重新启动 [英] Docker: Container keeps on restarting again on again

问题描述

我今天使用appcontainers / mediawiki docker映像部署了MediaWiki实例，但是现在遇到了一个新问题，无法找到任何线索。
尝试使用以下方式附加到mediawiki前端容器后：

  docker attach mediawiki_web_1 
  

由于我忽略的原因，它在我的配置中回答了 Terminated ，还尝试了： / p>

  docker exec -it mediawiki_web_1 bash 
  

我确实收到错误消息附近的内容：

 守护程序的错误响应：Container 81c07e4a69519c785b12ce4512a8ec76a10231ecfb30522e714b0ae53a0c9c68 is重新启动，等到容器正在运行
  

这是我的新问题，因为此容器永不停止重新启动。我可以看到，使用 docker ps -a 总是返回重启（127）x秒前的状态。 / p>

问题是，我能够停止容器（经过测试），但是再次启动它似乎使它回到了重新启动的循环中。

任何想法在这里可能是什么问题？直到我尝试附加它为止，整个过程都正常工作了。

我很伤心：-（

解决方案

docker日志

<$ p $ c> 命令将向您显示不以交互方式运行容器时容器正在生成的输出。 $ p> docker日志--tail 50 --follow --timestamps mediawiki_web_1


您还可以使用 docker run -ti< your_wiki_image> 在前台运行一个新容器，以查看其作用，您可能需要从<$中映射一些配置c $ c> docker-compose yml到 docker 命令。

猜测附加到媒体Wiki进程会导致崩溃，从而损坏您的数据。

I today deployed an instance of MediaWiki using the appcontainers/mediawiki docker image, and I now have a new problem for which I cannot find any clue. After trying to attach to the mediawiki front container using:

docker attach mediawiki_web_1

which answers Terminated on my configuration for a reason I ignore, trying also:

docker exec -it mediawiki_web_1 bash

I do get something close to an error message:

Error response from daemon: Container 81c07e4a69519c785b12ce4512a8ec76a10231ecfb30522e714b0ae53a0c9c68 is restarting, wait until the container is running

And there is my new problem, because this container never stop restarting. I can see that using docker ps -a which always returns a STATUS of Restarting (127) x seconds ago.

The thing is, I am able to stop the container (I tested) but starting it again seems to bring it back into its restarting loop.

Any idea what could be the issue here ? The whole thing was properly working until I tried to attach to it...

I am sad :-(

解决方案

The docker logs command will show you the output a container is generating when you don't run it interactively. This is likely to include the error message.

docker logs --tail 50 --follow --timestamps mediawiki_web_1

You can also run a fresh container in the foreground with docker run -ti <your_wiki_image> to see what that does. You may need to map some config from your docker-compose yml to the docker command.

I would guess that attaching to the media wiki process caused a crash which has corrupted something in your data.
