Trouble with tutorial and basic pipelines - failed to stream out from volume


I am new to concourse and have been going through the tutorials and documentation. I’m running into trouble early on though: even a simple hello-world invocation fails with message “failed to stream out from volume”. My task is below:

platform: linux

type: docker-image
source: {repository: busybox}

path: echo
args: [hello world]

Has anyone else seen this? Any idea on how to resolve?

This is a fresh installation of Centos, with kernel upgrade, docker, and docker-compose, running on a Virtual Box VM.
Docker and docker-compose both appear to be working fine.

Thanks -
