Description Avesh Agarwal 2016-01-22 20:58:44 UTC

Description of problem:

Due to recent changes in kube upstream (https://github.com/kubernetes/kubernetes/pull/19675), the container run time status is being verified based on docker's Version instead of APIVersion as done before. Since docker on fedora or rhel appends distro string (1.9.1-fc22/el7) to its version, kube parser fails to parse as the last part 1-fc22 is not integer. It was not an issue before as I said because APIVersion was being used which does not have this issue. For example:

$ docker version
Client:
 Version:         1.9.1-fc22
 API version:     1.21
 Package version: docker-1.9.1-4.git64eb95e.fc22.x86_64
 Go version:      go1.5.3
 Git commit:      64eb95e/1.9.1
 Built:
 OS/Arch:         linux/amd64

Server:
 Version:         1.9.1-fc22
 API version:     1.21
 Package version: docker-1.9.1-4.git64eb95e.fc22.x86_64
 Go version:      go1.5.3
 Git commit:      64eb95e/1.9.1
 Built:
 OS/Arch:         linux/amd64

Here are some errors, I noticed on kube nodes:

E0122 10:24:18.435492   27245 manager.go:986] docker: failed to parse docker server version "1.9.1-fc22": Unable to parse version "1.9.1-fc22": "1-fc22" is not an integer
E0122 10:24:23.273679   27245 manager.go:986] docker: failed to parse docker server version "1.9.1-fc22": Unable to parse version "1.9.1-fc22": "1-fc22" is not an integer
E0122 10:24:23.273692   27245 kubelet.go:2579] Container runtime sanity check failed: docker: failed to parse docker server version "1.9.1-fc22": Unable to parse version "1.9.1-fc22": "1-fc22" is not an integer

Detailed logs: http://pastebin.test.redhat.com/342892

As container run time status fails, all nodes in kube cluster are going down from Ready to NotReady status (it takes almost 5m in my setup). 


Version-Release number of selected component (if applicable):
docker-1.9.1-el7

How reproducible:
always

Steps to Reproduce:
1. git clone kubernetes which has https://github.com/kubernetes/kubernetes/pull/19675
2. cd kubernetes
3. make clean all
4. ./hack/local-up-cluster.sh
5. kubectl get nodes (wait for around 5 or more mins and see node status changes to NotReady
6. check kubelet logs: cat /tmp/kubelet.log and notice errors regarding 1-fc22 or 1-el7 not an integer.

 

Actual results:
docker version shows Version as 1.9.1-fc22/el7

Expected results:
docker version shows Version as 1.9.1
