config.rb Optional Settings

[edit on GitHub]

In addition to the default settings in a knife config.rb file, there are other subcommand-specific settings that can be added. When a subcommand is run, knife will use:

1. A value passed via the command-line
2. A value contained in the config.rb file
3. The default value

A value passed via the command line will override a value in the config.rb file; a value in a config.rb file will override a default value.
