Public bug reported:
Deployment details:
template:
cluster_distro: fedora-atomic
network_driver: calico
image:
Fedora-Atomic-27-2018041
labels:
{'kube_tag': 'v1.15.4', 'kube_allow_priv': 'true', 'ingress': 'nginx',
'tiller_enabled': 'true', 'tiller_tag': 'v2.13.1'} |
Issue:
The calico deployment fails and I see the following in the system logs:
Unable to update cni config: No networks found in /etc/cni/net.d
Container runtime network not ready: NetworkReady=false
reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni
config uninitialized
The directory /etc/cni/net.d is empty.
When I try to deploy calico manually with the following commands:
CALICO_DEPLOY=/srv/magnum/kubernetes/manifests/calico-deploy.yaml
/usr/local/bin/kubectl apply -f ${CALICO_DEPLOY} --namespace=kube-system
I get the following:
The DaemonSet "calico-node" is invalid:
spec.template.spec.containers[0].securityContext.privileged: Forbidden:
disallowed by cluster policy
I believe this is caused by missing --allow-privileged=true flag in kube
apiserver config.
This is a workaround that fixed it for me, along with label:
'kube_allow_priv': 'true':

Not sure if I missed any config options but I could not find if the flag
was added anywhere else.
