Issue in elastic search while building testbed using compose-services

Hi !

Thanks for the update. Now the reverse-proxy is working however we are getting 'Internal Server Error'. On investigation we found following error in sheepdog service.

sheepdog-service | ERROR:root:Rolling back session [404] - program getschema not found
sheepdog-service | [2020-01-30 20:43:17,841][sheepdog.api][ ERROR] [404] - program getschema not found

Pls suggest.
