   @Coqueiro it actually not completely correct, but will work in your case.
   
   Underneath this connection string converted to dict using "json.loads" and eventually in the code the following check applied:
   
   ```
           in_cluster = extras.get("extra__kubernetes__in_cluster")
   
           if in_cluster:
               self.log.debug("loading kube_config from: in_cluster configuration")
               config.load_incluster_config()
               return client.ApiClient()
   ```
   
   If you provide any string in the value of {"extra__kubernetes__in_cluster":"<any non empty string>"} you will enter IF clause as soon as bool("<any non empty string>") == True.
   
   The correct connection string will be:
   ```
   {"extra__kubernetes__in_cluster":true}
   ```
