I am trying to use kompose convert on my docker-compose.yaml files however, when I run the command:
kompose convert -f docker-compose.yaml
I get the output:
WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafka-connect" isn't supported - ignoring path on the host
WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafka-elasticsearch" isn't supported - ignoring path on the host
WARN Volume mount on the host "/home/centos/Sprint0Demo/Servers/elasticSearchConnector/etc/kafak" isn't supported - ignoring path on the host
It also says more warning for the other persistent volumes

Does anyone know how I can fix this issue? I was thinking it has to do with the error message saying that its a volume mount vs host mount?
I have made some research and there are three things to point out:
kompose
does not support volume mount on host. You might consider using emptyDir instead.
Kubernetes makes it difficult to pass in host/root
volumes. You can try with hostPath. kompose convert --volumes hostPath
works for k8s.
Also you can check out Compose on Kubernetes if you'd like to run things on a single machine.
Please let me know if that helped.
