docker容器不会以Mysql docker映像启动

docker容器不会以Mysql docker映像启动,docker,docker-machine,Docker,Docker Machine,我使用docker容器和mysql官方图像创建了11个以上的数据库容器(container1到container11)。设置后,所有集装箱运行正常,直到集装箱9。在container10,它只启动约1分钟,然后再次停止。使用docker日志检查容器,但我没有看到任何内容。停止container9,然后重新启动container10。它又跑起来了。这种情况似乎只有在我拥有9个mysql容器并试图提升到第10个时才会发生。如果我阻止其中一个,再把它举起来。那就没问题了。是虫子吗?还是我错过了dock

在后台运行
docker events
,然后尝试启动第10个容器。你肯定会看到出了什么问题。下面给出了一个启动已退出容器的示例,以及启动时出现的错误。按顺序执行以下命令:

~$ sudo docker events &
[1] 9414

~$ sudo docker start 48137950f1b7

希望你能理解。

我想我在一周后找到了解决方案,尽管我不太明白会发生什么。以下是我尝试过的,到目前为止,我可以将mysql容器设置为20个,没有问题

1:尝试创建一个Dummy mysql容器进行测试

$ docker run -e MYSQL_ROOT_PASSWORD=password mysql
Unable to find image 'mysql:latest' locally

并点击EAGAIN失败的io_setup()的错误代码

2:检查aio max nr的当前值

$ sysctl fs.aio-max-nr
fs.aio-max-nr = 65536
3:将aio max nr的值增加到2097152

$ sudo sysctl -w fs.aio-max-nr=2097152
3:启动mysql服务


4:尝试创建更多的mysql容器,并毫无问题地调出原始容器

您的系统有多少内存?64g,52g已使用,11G免费您是否在docker容器中运行此功能?那么docker中的docker呢?是的,当我在我的aws ec2Do a
df-h
中启动docker时,当故障发生时,docker映像中的docker也会发生。网络连接0303…dec(container=,name=bridge,type=bridge)卷装载5a…117(container=,destination=/var/lib/mysql,driver=local,propagation=,read/write=true)容器启动(image=mysql/mysql服务器:5.7,name=)container die(exitCode=1,image=mysql/mysql服务器:5.7,name=)network disconnect 0303…dec(container=,name=bridge,type=bridge)volume unmount 5a…117(container=,driver=local)预期所有进程,我看不到任何进一步的信息您刚刚保存了我的a*s!非常感谢!
