I am doing a sanity check before I open a support case… is it the case that cloud-config will make changes to the DNS service somehow? The cloud config docs seem to imply that yes this is possible, at least the way it’s worded.
After each ROS install we are seeing some odd entries, in some cases causing disruption to existing names (such as “rancher.mycompany.org” loses the IP we assigned to it after suspected rancheros install).
Is there any way to stop rancheros install from making changes to DNS?
Or is this impossible and therefore something in our current environment we are confused about?
Cloud config DNS section:
rancher: network: dns: domain: - mycompany.org nameservers: - x.x.x.x - x.x.x.x search: - mycompany.org
