Docker supported kernel version list for centos 7


(Karthickikm19) #1

Hi All,

My kernel current kernel version is 3.10.0-514.26.2.el7.x86_64, current OS version CentOS Linux release 7.3.1611 (Core), docker version 17.03.0-ce and Rancher version v1.5.9

If I upgrade my kernel version to 4.9.72, will it cause the docker and rancher?

And also I need the docker supported kernel version list.

Please help me on this.

"OS requirements
To install Docker CE, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested.

The centos-extras repository must be enabled. This repository is enabled by default, but if you have disabled it, you need to re-enable it.

The overlay2 storage driver is recommended."

So looks like all kernels included in CentOs 7 and above are supported.
Also you can run old docker ce version in a new kernel version, but i think is easier upgrade the docker version at the same time of your kernel.

I have one more question that if i run rancher server and agent in different kernel version will cause any problem.
