Ok, this might work.
Will try it.

Thanks for the update.

I spot a CLI question?

But if you have created a service instance and later you want to bind it

to a new app, can you add the tag expected by that app to the existing
service instance?



`cf update-service mydb -t "list, of, tags"`

Yes, tags at service instance level could work.

But if you have created a service instance and later you want to bind it
to a new app, can you add the tag expected by that app to the existing
service instance?

Also tags do not identify a service instance uniquely, so it is still
possible that an app is bound to multiple instances with the same tag.

I have seen many apps that scan VCAP_SERVICES for a service with specific
properties and pick the first match. This is error prone as there could be
multiple matches.



So I think binding names would be more explicit and tags seem more like a
workaround.

One can supply arbitrary tags for service instances: https://apidocs.clo

This is not at the binding level, but you could tag your instances as
"secure" and filter on that. Does this help your use case?

This is a great idea. Today to get around this issue my org names our
service instances with a #value at the end and we use custom VCAP_SERVICES
client libraries to ignore anything after the #. That allows us to have a
service named oracle-db#dev and oracle-db#test both be found in
configuration with the name "oracle-db". This proposal would fix that
issue for my org.

Hi,



Selecting the right service binding from application code in Cloud
Foundry is often ambiguous and error prone. To address this, I propose to
introduce a service binding name.



The proposal is described in details here

Looking forward to your comments.



Best regards,
