Contain yourself – StorageOS is coming
Found on The Register on Monday, 20 June 2016
StorageOS is a UK-based startup offering simple and automated block storage to stateless containers, giving them state and the means to run databases and other applications that need enterprise-class storage functionality without the concomitant complexity, rigidity and cost.
Or, you could just drop the additional docker layer and install your database like you did before. Not everything in this universe has to be container-ized.
