Fix: #153.
Instead of adding a new
--allow-download
flag as stated on the issue, enable Viper to work with environment variables.Kuberlr will honour environment variables with a name matching the key uppercased and prefixed with
KUBRERLR
(likeKUBERLR_ALLOWDOWNLOAD
) and use them for the config settings.These environment variables take precedence over the config file settings.
