kompose: Cannot kompose up

Hi, I’ve been working on some docker project and wanna transform them into a kubernetes cluster.

➜  iotanode_dockerized git:(master) kompose -f docker-compose.yml convert

ath on the host

INFO Kubernetes file "iri-node-claim2-persistentvolumeclaim.yaml" created
INFO Kubernetes file "iri-node-claim3-persistentvolumeclaim.yaml" created

The convert went okay but when I try to kompose up, here’s what happens:

➜  iotanode_dockerized git:(master) ✗ kompose -f iri-node-deployment.yaml up
