我可能误会了什么。ubuntu:12.10 内核不应该高于 ubuntu:12.04 内核吗?
$ sudo docker run ubuntu:12.04 /bin/uname -a
Linux cb466a57b8c2 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
$ sudo docker run ubuntu:12.10 /bin/uname -a
Linux 62aadcf4e486 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
这是版本信息:
$ sudo docker version
Client version: 0.5.3
Server version: 0.5.3
Go version: go1.1
