Re: How to setup wildcard DNS subdomain




Thank you so much for your information. 


So i am currently testing it. But I have hosted my cloudera single node environment on AWS EC2 instance. 


I also own a domain on godaddy I have changed the nameserver to the one in AWS DNS Zone. Should the hosted zone be public ? or private in a vpc?



But i am not sure how to proceed next. What are the steps which i should take post this one ?

This depends on your corporate network configuration.  Private zones are only resolvable within your AWS VPC, so unless you have your corporate network connected to your VPC and DNS peering properly configured, it is often easier to configure DNS in your public zone.  You will want to set both and * A name records to your master node.  Within AWS, it's often more flexible to point this records to an EIP so you can attach it to different nodes over time.

Now what should i do next in AWS? Create a record set in AWS? 


And what should i do on my EC2 instance where the Workbench has been installed?

Pasted below is part of instructions for setting up DNS subdomain:


To access Cloudera Data Science Workbench, you must configure the wildcard DNS name *.cdsw.<company>.com for the master host as an A record, along with a root entry for cdsw.<company>.com.


My question: Does "master host" above refer to the edge node or the name node of the cluster?
