Comb Variables

Variables make a Comb reusable across Cells with different configuration values.

Schema

Each variable should have a name, type and default where appropriate. Mark values required when installation or startup cannot proceed without them.

Template use

Variables can be referenced by the parts of the Comb that support templating, such as startup commands or installation URLs.

Good variable design

Keep names short and obvious. Avoid exposing internal values that should remain fixed by the Comb itself.

Defaults

A good default should create a useful Cell without requiring an administrator to understand every implementation detail of the underlying server.
