Description Micah Abbott 2016-03-01 10:05:25 EST
Description of problem:

In the documentation for setting up a Kubernetes cluster [1], the configuration of flannel instructs the user to use an etcd config key of '/coreos.com/network'.  However, the flannel package is shipped with a default value of '/atomic.io/network'.  I think it would be preferable to use this default value in place of the 'coreos.com' value.

[1] https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/version-7/getting-started-with-containers/#creating_a_kubernetes_cluster_to_run_docker_formatted_container_images

In section 3.5 "Setting up Kubernetes on the Master", the following commands/instructions should be changed:

# etcdctl set coreos.com/network/config < flannel-config.json

...should be changed to...

# etcdctl set /atomic.io/network/config < flannel-config.json

# etcdctl get coreos.com/network/config

...should be changed to...

# etcdctl get /atomic.io/network/config

The config file '/etc/sysconfig/flanneld' should have the following content:

The same change will need to be made in section 3.6 "Setting up Kubernetes on the Nodes", Step 5.

I'll fix this for RHEL/Atomic 7.3.
Comment 5 Chris Negus 2017-03-13 16:04:46 EDT
The chapter identified here was corrected to use "atomic.io" as the base for the etcd configuration information. However, the chapter has since been dropped, because we no long support manual configuration of multi-node Kubernetes. I checked the other documentation in this area and we do properly identify "atomic.io" as the configuration base in our flannel documentation[1]. I think we can close this bug.
