[RFE] Allow for DNS to update multiple Masters (or have re-try logic).
Last modified: 2016-07-26 08:57:07 EDT
Description of problem:
Add support for the OSE DNS plugin to update more than 1 DNS server (at a time).
In a Master -> (Slave NS1 <--> Slave NS2) DNS setup, if the master is ever goes down so does your ability to create applications or scale applications.
Version-Release number of selected component (if applicable): 2.2.7 and prior.
How reproducible: 100%
Steps to Reproduce:
1. Setup OSE
2. Setup Bind with 1 master, and 1 slave
3. Configure Broker and Nodes to use Slave an DNS (resolve resource).
- Configure the Broker to update the DNS master (in DNS plugin).
4. Stop the Master
5. Create an application
Scale and application
DNS failures will be seen and applications are rolled back.
The DNS plugin should (quickly) identify failures with the first DNS (master) and update a second, to avoid this type of outage.
