Configuring the Proxy API Zone

You configure a set of DNS records for the new API Proxy zone. For API clients, you create a single A record and at least one CNAME record for the zone. Each CNAME record provides the assignments for each AWS service endpoint to the appliance acting as the AWS API Proxy. Do the following:

In the Data Management tab -> DNS tab -> Zones panel, select the new API Proxy zone, expand the Toolbar, and then click Add -> Record -> A Record.
In the Add A Record wizard, do the following:
- Name: Enter the hostname of the appliance or virtual appliance to be applied to the new A record. The displayed zone name should be the API Proxy zone you just created. If no zone name appears, or if you need to specify your new API Proxy zone, click Select Zone. When there are multiple zones, Grid Manager displays the Zone Selector dialog box. Select the API Proxy zone name in the dialog box and then click OK. The name you enter is prefixed to the DNS zone name, and the complete name becomes the FQDN (fully qualified domain name) of the host. For example, if the zone name is api-proxy and you enter gridmaster as the host name, then the FQDN for your A record would be, in this example, gridmaster.api-proxy.
- In the IP Addresses section, enter the IP address of the appliance or virtual appliance (the Grid Master, in this example) acting as the API Proxy.
- Comment: Optionally, enter descriptive information about the A record.
Save the configuration. Click Restart if it appears at the top of the page. If a message appears requesting "Cannot create a PTR record for <ip_address> because there is no reverse-mapping zone in the system. Only the A record will be created. Do you want to continue?", click Yes.
You now create the CNAME records for each of the AWS service endpoints.
In the Data Management tab -> DNS tab -> Zones panel, select the new API Proxy zone, expand the Toolbar, and then click Add -> Record -> CNAME Record.
In the Add CNAME Record wizard, do the following:
- Alias: The zone name you selected appears to the right of the Alias field. Enter the alias for the canonical name. For API Proxy, Infoblox recommends making the alias recognizable for the relationship to AWS regional endpoints. For example, enter ec2-us-west-1 as a recognizable alias for the CNAME record that you will associate with the AWS region ec2.us-west-1.amazonaws.com. Click Select Zone to select a DNS zone from the Zone Selector dialog box. If you have only one zone, Grid Manager displays the zone name here when you click Select Zone.
- Canonical Name: This field displays the domain name of either the current zone or the last selected zone. To add a CNAME record to the new API Proxy zone, enter the complete canonical (or official) name of the host that acts as the API Proxy. Example: gridmaster.api-proxy. This value derives from the A record.
Save the configuration. Click Restart if it appears at the top of the page. To add a second CNAME record, do the following:
In the Data Management tab -> DNS tab -> Zones panel, select the API Proxy zone, expand the Toolbar, and then click Add -> Record -> Add CNAME Record.
In the Add CNAME Record wizard, do the following:
- Alias: Click Select Zone to select a DNS zone from the Zone Selector dialog box. If you have only one zone, Grid Manager displays the zone name here when you click Select Zone. Then, enter the alias for the canonical name. For API Proxy, Infoblox recommends making the alias recognizable for the relationship to AWS regional endpoints. For example, enter ec2-us-west-2 as a recognizable alias for the CNAME record that you will associate with the AWS region ec2.us-west-2.amazonaws.com.
- Canonical Name: This field displays the domain name of either the current zone or the last selected zone. To add a CNAME record to the new API Proxy zone, enter the canonical name of the host that acts as the API Proxy. Example: gridmaster.api-proxy.
Save the configuration. Click Restart if it appears at the top of the page.
