Using your own domain cname to access cloud elastic instance?

[dadoonet (David Pilato)]

As the link has been removed ans some people still find this answer, I'm linking to another more recent post which has more information:

Elastic Cloud custom domain?

Hey Alberto It's not fully supported today as the browser will complain about TLS as the certificate won't be for the same domain. You can define a CNAME. If your cluster is for example abcdef.us-east-1.aws.found.io you can add a CNAME my-es-cluster in your DNS which goes to abcdef.us-east-1.aws.found.io. It will be fully supported in the future AFAIK. But no ETA on this though.
