kubectl create configmap pipeline-akamai --from-file pipelines.yml
kubectl create -f cdn_akamai.yml

where the files are

But I get Error or CrashLoopBackOff as

I had running a hello word pod to verify if my cluster is ok, and this pod run perfectly.

Could you help me, please? Is there any problem with my volumes, service, syntax, Do you see anything?
