### Key format recommendations
A label key is the left-hand side of the key-value pair. Keys are alphanumeric
strings which may contain periods (`.`) and hyphens (`-`). Most Docker users use
strings which may contain periods (`.`), underscores (`_`), and hyphens (`-`). Most Docker users use
images created by other organizations, and the following guidelines help to
prevent inadvertent duplication of labels across objects, especially if you plan
to use labels as a mechanism for automation.
