Docker rabbitmq图像出现[错误]太短的cookie字符串失败

Question

似乎我确实有一个问题，在我的Windows机器运行对接机桌面上的rabbitmq和rabbitmq管理对接器映像。

当尝试运行它时，在它关闭之前会出现以下日志：

我已经使用这个图像几个月了，没有任何问题，但突然之间，它不再工作了。

我还试着在我的覆盆子皮上运行这个。结果它在那里起作用了，所以这对我来说更像是本地的事情，这有点奇怪，因为码头工人基本上是为了避免这些问题。

我还尝试将RABBITMQ_ERLANG_COOKIE环境变量设置为长名称，但没有成功。有什么想法吗？

Answer 1

似乎RabbitMQ没有空间可以编写cookie：21:01:21.726 [error] Failed to write to cookie file '/var/lib/rabbitmq/.erlang.cookie': enospc

也许你在码头有一些空间限制，或者你实际上没有空间在主机上？

Answer 2

我也犯了同样的错误，听从了欧文·布朗的建议。不幸的是，删除rabbitmq映像不能解决我的问题，但删除所有其他冗余映像(特别是较大的图像)也为我解决了问题。

如果您想知道所有图像的大小，您可以使用

docker system df

编辑：

几个小时后，当我再次遇到同样的问题时，我又研究了一下，发现了this answer，它解决了我的麻烦。

比删除图像更重要的是使用以下方法删除卷：

docker volume rm $(docker volume ls -f dangling=true -q) //删除所有卷

Answer 3

使用docker run rabbitmq:management隔离启动兔in。

如果仍然收到“未能写入cookie文件”/var/lib/ RabbitMQ /.erlang.cookie‘：enospc“错误，则会导致问题，因为RabbitMQ使用的文件已损坏。

因为一旦发生错误，容器就会退出，并且容器是从缓存的坞映像启动的，所以您将无法进入容器来修复这个问题。相反，您需要删除缓存的映像。

1. 消除了原始问题的原因，这可能是分配给Docker的内存不足。您可以通过docker的utility.
2. Delete删除图像或分配更多的内存--无论是rabbitmq停靠器图像docker images | grep rabbit，还是每个图像id的run docker rmi <image_id(s)>。
3. 删除所有缓存的图像。列出所有使用$ docker rmi $(docker images -f "dangling=true" -q)

的图像，然后用$ docker images --filter "dangling=true删除它们

最后，使用docker run rabbitmq:management再次运行rabbitmq。如果它运转正常，你就会重新开始工作。
