[jira] [Commented] (WHIRR-347) Support provider-independent environment variables for cloud credentials

["Tom White (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WHIRR-347?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204917#comment-13204917 ] 

Tom White commented on WHIRR-347:
---------------------------------

Command-line options override those in the properties file (see statement in http://whirr.apache.org/docs/0.7.0/configuration-guide.html), so your precedence order needs changing I think.

In whirr-cli-defaults.properties could we have whirr.provider=${env:WHIRR_PROVIDER} rather than whirr.provider=${sys:WHIRR_PROVIDER} and avoid passing them as system properties from the script? 

Some tests and documentation would be good to have too. Also, how do we plan to change the recipes to use these?

> Adrian suggested that we support WHIRR_PROVIDER, WHIRR_IDENTITY, WHIRR_CREDENTIAL environment variables. This would allow users to set them for any cloud they are using.
