VAST Cluster supports a single instance of the DNS service. The DNS service listens for DNS requests on port 53 and runs on a dedicated IP.
The service instance supports a single DNS delegation that refers DNS requests with a common domain suffix. The DNS service resolves DNS names to VIP pools per short domain names configured per VIP pool.
To use the DNS service:
From the left navigation menu, select Network Access and then DNS.
-
In the Add DNS dialog, complete the fields:
If you want to immediately enable the DNS service, turn on the Enabled setting.
-
Click Create.
The DNS server configuration is created and appears on the DNS tab.
To configure the DNS server from the CLI, use the dns create command.
For example:
vcli: admin> dns create --name vast_dns --ip 192.0.2.0 --domain-suffix vastdata.ourcorp.com --gateway 192.0.4.0--enable --subnet-cidr 16
To display the configuration, run dns show or dns list.
To modify the configuration, run dns modify.
To delete the configuration, run dns delete.
