If you experience error something went wrong, please check:
Go to each node (masters and workers) to check if docker command works (docker ps). It's possible docker link broke after reboot. If this happens run the following command:
mount --rbind /ibm/docker_link /var/lib/docker
systemctl restart docker
Make sure docker is up in all the nodes then use kubectl command to check pods status.
kubectl config set-cluster mycluster --server=https://127.0.0.1:8001 --insecure-skip-tls-verify=true
kubectl config set-context mycluster --cluster=mycluster
kubectl config set-credentials mycluster --client-certificate=/ibm/InstallPackage/ibm-cp-app/cluster/cfc-certs/kubecfg.crt --client-key=/ibm/InstallPackage/ibm-cp-app/cluster/cfc-certs/kubecfg.key
kubectl config set-context mycluster --user=mycluster
kubectl config use-context mycluster
systemctl restart kubelet
---- Similar activities as above can be done using following script. This scripts generates commands that you can copy paste and run ----
# cat fix.sh
nodelist=`cat /etc/hosts | cut -d" " -f2 |grep fyre|egrep "master|worker" | sort |uniq`
rm -f m1.out d1.out k1.out
for i in $nodelist
do
echo ssh root@${i} \"mount --rbind /ibm/docker_link /var/lib/docker\" >>m1.out
echo ssh root@${i} \"systemctl restart docker\" >> d1.out
echo ssh root@${i} \"systemctl restart kubelet\" >> k1.out
done
cat m1.out d1.out k1.out
---- End of script ----
