Integration with Compute Cloud
You can assign domain names (FQDNs) to VMs as soon as you create them in Compute Cloud.
To add a VM to a zone when creating it, select the zone you need and set a domain name under DNS settings for internal addresses of Network settings. You can add multiple records, including in different zones. If you do not specify a zone, the VM will get a domain name in the standard zone of the subnet it will be connected to. For instructions on how to create a VM, see Creating a VM from a public Linux image.
For a VM's public IP address, integration with Compute Cloud is currently not supported. You can add an A record to a public zone manually after creating a VM. Learn more about how to create a record.
Automatic zone selection
If no zone is specified explicitly for a VM's additional DNS record, it will be selected automatically. For this you need to specify an FQDN ending with a period. In the management console, the period is added automatically.
A DNS record will be added to one of the private zones that can be accessed from the VM's virtual network and are FQDN suffixes. The most specific private zone will be selected from among those with suitable suffixes. If there are several suitable zones with the same domain name, one of them will be selected.
For example, in the network settings, FQDN is set to
hello.world.private., and the following four private DNS zones can be accessed from the virtual network:
- Service zone:
..- Custom zones:
staging.,private., andworld.private..The
staging.zone is out of consideration because thestaging.domain name is not a suffix of thehello.world.private.FQDN.From among of the zones with suitable suffixes (
.,private., andworld.private.),world.private.will be selected ans the most specific one.
Using Cloud DNS for instance groups
When creating a VM group, the name specified in the VM template will apply to all the VMs in the group. As a result, the created records will have the same FQDNs but different IPs.
To generate unique names, you can use variables in the template. For example, if the record name is web_server_{instance.index}, you can create records with unique names of the group's VMs. If the name is web_server_{instance.zone_id}, you can create records common for all VMs in the same availability zone.
