Docker daemon allows, according to documentatio, using memory storage driver for its images. Has anybody any daily business experiences with that?
According to the documentation, memory storage is intended for testing purposes only and should never be used in production. The only practical purpose I can think of for this might be state testing, such as with Serverspec or Inspec, to validate configurations. Using memory storage for this purpose might be a little faster and use less disk storage. I'm not sure those benefits are worth the effort to implement.
