# create deployment
$ kubectl create -f osrm.yaml  
deployment.extensions/osrm created

# create loadbalancer
$ kubectl create -f osrm_svc.yaml  
service/routing-osrm-service created

# OPTIONAL: checking deployment status, wait READY
$ kubectl get deployments -n routing-osrm
NAME   READY   UP-TO-DATE   AVAILABLE   AGE
osrm   0/1     1            0           20s
$ kubectl get pods -n routing-osrm
NAME                    READY   STATUS    RESTARTS   AGE
osrm-67b55f46c9-tpfgs   0/1     Running   0          22s

$ kubectl describe deployments -n routing-osrm
...
$ kubectl describe pods -n routing-osrm
...

# OPTIONAL: check container running log for troubleshooting
$ kubectl logs -f --timestamps=true  -n routing-osrm osrm-67b55f46c9-tpfgs
...

# start timed rolling update for traffic updating
$ crontab osrm_cron
$ crontab -l 
*/30 * * * * export PATH=$HOME/bin:$PATH && kubectl set env --env="LAST_MANUAL_RESTART=$(date -u +\%Y\%m\%dT\%H\%M\%S)" deploy/osrm -n routing-osrm >> ${HOME}/osrm_cron.log 2>&1

# OPTIONAL: if want to stop
