Hello there,
Occasionally some of our managed services work has us dealing directly with other cloud providers such as Amazon. One of our clients set a requirement to migrate over 5,000 domain’s to Amazon’s Route53 DNS service.
There was little doubt that this could be automated, but since we have never done this massive of a deployment through Amazon’s API directly, we thought it might be interesting to post the process as well as the script through which we managed the import process.
Essentially the script utilizes a master domain name list file as its basis for looping through the import. The master list refers to the bind zone files and imports them into Amazon’s Route53 via the Cli53 tool package.
One final note, the script outputs all completed domain imports into a CSV file with the following format :
domain.com,ns1.nameserver.com,ns2.nameserver.com,ns3.nameserver.com,ns4.nameserver.com
This is because when facilitating the actual nameserver change request, all the nameservers assigned to domains when imported to Route53 are randomly generated, so the script has to keep track of these nameserver/domain associations.
The script isn’t perfect and could benefit from some optimizations and more error checking (it does a lot of error checking already, however), but here it is in its entirety. We hope you will have some use for it!
