| Service Discovery |
For every workload created, a complementing Service Discovery entry is created. This Service Discovery entry enables DNS resolution for the workload's pods using the following naming convention:
<workload>.<namespace>.svc.cluster.local.
However, you also have the option of creating additional Service Discovery records. You can use these additional records so that a given namespace resolves with one or more external IP addresses, an external hostname, an alias to another DNS record, other workloads, or a set of pods that match a selector that you create.
-
From the Global view, open the project that you want to add a DNS record to.
-
Click Resources in the main navigation bar. Click the Service Discovery tab. Then click Add Record.
-
Enter a Name for the DNS record. This name is used for DNS resolution.
-
Select a Namespace from the drop-down list. Alternatively, you can create a new namespace on the fly by clicking Add to a new namespace.
-
Select one of the Resolves To options to route requests to the DNS record.
-
One or more external IP addresses
Enter an IP address in the Target IP Addresses field. Add more IP addresses by clicking Add Target IP.
-
An external hostname
Enter a Target Hostname.
-
Alias of another DNS record's value
Click Add Target Record and select another DNS record from the Value drop-down.
-
One or more workloads
Click Add Target Workload and select another workload from the Value drop-down.
-
The set of pods which match a selector
Enter key value pairs of label selectors to create a record for all pods that match your parameters.
-
-
Click Create
Result: A new DNS record is created.
- You can view the record by from the project's Service Discovery tab.
- When you visit the new DNS name for the new record that you created (
<recordname>.<namespace>.svc.cluster.local), it resolves the chosen namespace.
