Docker image/container upgrade best practise — by ahokanson, meyay and goffinf on Docker Community Forums

intermediateforum

A discussion of how to update a container when its image changes.

intermediatepage

Docs on persisting container data with volumes, which Docker calls the preferred mechanism, versus bind mounts that tie you to the host's folder layout. Mentions read-only mounts, subdirectory mounts, volume drivers for NFS/CIFS, and the gotcha that mounting over a non-empty directory hides its existing files.
