Kubernetes help. Kube-dns crashloopbackoff
-
Need help with kubernetes.
I have installed kuberentes in my centos 7.2 machine. When i type kubectl get pods --all-namespaces
I see the kube-dns has an error saying crashloopbackoff. I am unable to find the exact problem.
Somebody help on this ?

New to CentOS 7?
Disable SELinux and try again.setenforce 0If things work, then you can work on resolving the SELinux security concerns.
-
swapoff -a
setenforce 0
installed docker, kubeadm, kubelet, kubectl
enabled and started docker
Checked the cgroup driver for both docker and kube to be same with cgroupfs
kubeadm init with cidr range 10.244.0.0/2
and kubectl get pods --all-namespaces
Kube-dns crashbackloopoff.

Did you reboot someplace in there? Because
setenforce 0does not survive a reboot. -
I have disabled selinux=disabled.
-
fyi, i did not reboot the machine at all
-
Well, then I am no further help as I have not tried to use this container before.

I've not used kubernetes either, but, do you have an error log from when you tried to start it? Probably in /var/log and something like kube.log.
Also, are any nameservers listed in /etc/resolve.conf? Network settings like to drop the DNS server setting once in a while, and the DNS error might be caused by this.
-
Did you follow this from the kubeadm install setups?
I've done a cluster setup a couple of times and haven't run into this.
