Preparing apps for containeriziation

[markllama]

In the Best Practices list, perhaps I've missed it but I don't see much in the way of architectural guidelines:

• Decomposing your (host based) application/service
• exposing and defining container interfaces
  • network
  • shared files
• Container startup
  • avoid sequencing: Images must poll and self-assemble
  • balance in-container polling and Kube restart-on-exit looping
  • detecting uninitialized resources, initialize, handling race conditions
• Passing in parameters
  • environment variables
  • container startup CLI
  • host files (via volume)
  • config/setup tarballs (from remote)

Others?
