Controller Configuration
This document describes the configurations on the Controller under Settings tab.
DNS Server
When “Use VPC/VNET DNS Server” is enabled, the Controller’s DNS server is provided by the DHCP option of the VPC where it is launched. The DHCP option contains DNS server which could be on-prem, thus if there is DNS reachability issue, there is network outage issue.
When “Use VPC/VNET DNS Server” is disabled, the controller uses Google public DNS server, therefore making the controller’s DNS reachability independent of customer’s configuration. This is recommended configuration.
Login Customization
Enable/Disable Admin Login
The “admin” account login can be disabled to instead use account user.
To disable admin login to the Controller, go to Settings -> Controller -> Login Customization. Click Disable.
Note that you need a local user with admin privileges to be created first, before you can disable the “admin” account.
