Distributed Docker Volumes Fun
summary
A small tool called sink tars a Docker volume every few seconds, pushes the tarballs into the dat repository, and a slave untars them into a second host directory so two containers can run off replicated volumes; demo shows live files appearing on the replica and an engine-x style read-only failover plan for outages. It works for small frequent changes, struggles with very large single files, is not yet a Docker plugin, and aims to provide continuous, versioned off-host backups.
