Subject Re: Include cartridge name in pod id
Date Wed, 19 Aug 2015 05:00:42 GMT
Hi Udara,

We got the same issue for podLabel and ServiceLabel since we used cluster
id [1 <https://issues.apache.org/jira/browse/STRATOS-1499>] when creating
pods and services. The idea was to use cluster-x instead of lengthy cluster
id.
If we use pod-x, service-x, cluster-x, there won't be any way to identify
which pod/service is related to which Stratos service/cluster. Then again,
we can't allow users to enter lengthy application, cartridge names/aliases
due to this character constraint.

So as Imesh suggested one of the workarounds would be to use logs to
identify pods and services. But if there's a better approach we can try
that as well.

Thanks,
