 	All values will be automatically (base64) encoded _except_ the `key_json` values under `gcs`/`gcr`.  These must be base64-encoded.  This is to support cleanly passing said encoded text via `helm --set` cli functionality rather than attempting to pass the raw JSON data.  For example:
 
 		$ helm install workflow --namespace drycc \
-                        --set controller.platform_domain=youdomain.com

 You are now ready to run `helm install drycc/workflow --namespace drycc -f values.yaml` using your desired object storage.

 Of course, if you deploy it on a bare machine, you probably don't have Load Balancer. You need to use NodePort:
 ```
 $ helm install drycc/workflow --namespace drycc \
     --set global.ingress_class=nginx \
-    --set controller.platform_domain=drycc.cc \
+    --set global.platform_domain=drycc.cc \

 If you want to use Load Balancer on a bare machine, you can look at [metallb](https://github.com/danderson/metallb)
