Riak in Docker - Error folding keys - incomplete_hint

Can't say I've paid enough attention to the logs in my single-machine
Riak within Docker setups to confirm.

Do you have the container image definitions somewhere public? That may
help someone reproduce the issue. Also, did you ensure that the Riak
data directory is setup as a Docker volume?

Other things that come to mind:

- What OS is the Docker host running?
- What storage driver are you using for Docker?
- What file system is the Docker data directory using?
