Regular expressions (perl format) should be used to specify wildcard. '/' used on the end of group name to distinguish regexp from simple string. groups: '/.*/' # any group groups: '/^(?!controller$)/' # all groups except controller groups: '/(?=controller)(?=^((?!^primary).)*$)/' # all controller, except primary-controller groups: '/mongo|compute/' # mongo or compute DocImpact Closes-Bug: #1480930 Change-Id: I1f279fbd585775fc7b5af1ecbbaa24be21d831c9
