+        attach        deploy        exec          list          logs          start         template
+        delete        deploy-local  instances     log-history   restart       stop          validate
+        $ ec ioc instances <tab> <tab>
+        $ ec ioc instances bl01t-ea-ioc-0 <tab> <tab>
+        bl01t-ea-ioc-01  bl01t-ea-ioc-02
+
