+**_Version 1.0_ example for using a .tags file**

+Use .tags file option: USE_TAGS_FILE<br/>
+The default is FALSE unless the value of USE_TAGS_FILE is one of: y,Y,t,T,true,TRUE,yes,YES<br/>
+The .tags file was used by the docker plugin when we created out container<br/>
+A .tags file is a comma separated list of tags: 1.0.1,1.0,1,latest (see docker plugin docs)<br/>
+We will use the first tag in the list, so create your file accordingly
