如果我的主机是12.04，是否可以使用docker image ubuntu 14.04？

Question

我将ubuntu 12.04作为主要主机，可以在其上运行dockerized的 ubuntu 14.04吗？

Answer 1

The stock Linux kernel that came with 12.04 didn't have support for the required AUFS file system. Later installs did however install the kernel v3.8 and later, so so you can upgrade and run Docker fine.

# install a Docker compatible kernel on Ubuntu 12.04, if it is not already v3.8+
# "uname -r" will tell you the current version running
sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring
sudo shutdown -r now

Answer 2

是的，因为您可以在Ubuntu 12.04上启动基于Fedora / Centos / ArchLinux ...的Docker容器
