Story #6338

Updated by ipanova@redhat.com over 4 years ago

Add the ability to limit tag using a regexp wildcard character '*' 

 For example: 

 upstream taglist is 
 ``` 
 [ 
 'openshift-4', 
 'openshift-3.11' 
 'openshift-3', 
 'openshift-3.10' 
 'latest' 
 'foo' 
 ]` 
 ``` 

 When specifying `whitelist-tags=[openshift-3.*, latest, bla-bla]` it will mirror down **only**: 
 ``` 
 [ 
 'openshift-3.11' 
 'openshift-3', 
 'openshift-3.10' 
 'latest' 
 ] 
 ``` 


 **solution** 

 ``` 
 In [61]: upstream_tags = [  
     ...: 'openshift-4',  
     ...: 'openshift-3.11',  
     ...: 'openshift-3',  
     ...: 'openshift-3.10',  
     ...: 'latest',  
     ...: 'foo'  
     ...: ]
