Stop?

Currently, CentOS only supports Docker in the released version.

Docker runs on CentOS 7 and requires a 64-bit system and a system kernel version later than 3.10.

Docker is running in? CentOS-6.5? For CentOS of a later version, the system must be 64-bit, the system kernel version is 2.6.32-431, or a later version.

 

View the kernel version:

uname -r

Installation:

# yum -y install docker

Start the service:

# service docker start

Check and install:

# docker run hello-world
