Welcome to the kubernetes-contrail-cheatsheet wiki!

To get all contrail pod status:

for pod_name in `kubectl get pods -n kube-system -o wide | grep contrail | awk '{print $1}'`; do kubectl exec -it  $pod_name -n kube-system -- contrail-status ; done

Save kube docker id:

kubeid=$(docker ps | egrep kube-manager | egrep -v pause | awk '{print $1}')

Restart all contrail services in one go:

for pod_name in `kubectl get pods -n kube-system -o wide | grep contrail | awk '{print $1}'`; do for serv in `kubectl exec -it  $pod_name -n kube-system -- contrail-status | awk '{print $1}' | egrep -v == `; do servic=$(echo -n $serv | head -c -1); echo $pod_name $servic restarting ; kubectl exec -it  $pod_name -n kube-system -- service $servic restart; done  ; done

Manually run contrail-kube-manager:

/usr/bin/python /usr/bin/contrail-kube-manager -c /etc/contrail/contrail-kubernetes.conf

Manually restart all service in contrail container:

for a in `contrail-status  | awk '{print $1}' | egrep -v ==`; do servic=$(echo -n $a | head -c -1); service  $servic restart; done

If you get libcrypt error install faollowing

wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/7110687/+files/libgcrypt11_1.5.4-2ubuntu1.1_amd64.deb

sudo dpkg -i libgcrypt11_1.5.4-2ubuntu1.1_amd64.deb

Load untared images

for master_img in `ls |  egrep -v 'agent|dependents|kubernetes-docker|networking' `; do  docker load -i $master_img; done

Custom output

kubectl get services -o=custom-columns=NAME:.metadata.name,Type:.spec.type

kubectl get services -o jsonpath='{.items[*].spec.clusterIP},{.items[*].metadata.name}'

kubectl get services -o json | jq -r '.items[].metadata.name'

kubectl get services -o json | jq '.items[] | {Name: .metadata.name, Type: .spec.type, ClusterIP: .spec.clusterIP}'

Running cadvisor to get stats:

 sudo docker run   --volume=/:/rootfs:ro   --volume=/var/run:/var/run:rw   --volume=/sys:/sys:ro   --volume=/var/lib/docker/:/var/lib/docker:ro --privileged=true --volume=/cgroup:/cgroup:ro   --publish=8080:8080   --detach=true   --name=cadvisor   google/cadvisor:latest

Note: To make it work on openshift:

mount -o remount,rw '/sys/fs/cgroup'
ln -s /sys/fs/cgroup/cpu,cpuacct /sys/fs/cgroup/cpuacct,cpu
