pod network add-on flannel : diff between 'kubernetes official doc url' and 'github url' for kube-flannel.yml

I'm installing pod network addon flannel to my cluster.

On the official kubernetes doc, the url to install flannel add-on is

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/62e44c867a2846fefb68bd5f178daf4da3095ccb/Documentation/kube-flannel.yml

and on the github repository wiki, the url is 

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

So what is the diff ? Which url should I apply ?

thank you for some help

Solution

  • They are the same document, but potentially different versions. You can view the version history, and observe that 62e44c867a28 is (as of this answer) the second-most-recent version.

    That particular change is described at https://github.com/coreos/flannel/pull/1162 - basically updating definitions from a beta format to a newer format that is less likely to change going forward.
