DNS Records in Horizon

DNS Zones

A DNS zone should automatically be created for your project with format PROJECT.projects.jetstream-cloud.org.

If you click on the zone name, then open up the “Record Sets” tab, you should see a list of records for your project’s DNS zone. On a new project with no instances, you should see the following records:

• SOA - Start of authority record
• NS - Name server

Manually Creating an A Record

Every time you create or unshelve an instance, the instance should automatically receive a public IP and automatically generate an A record.

If your instance fails to automatically receive an A record, you can use these steps to manually create and assign an A record to your instance.

1. Take note of the name of your instance as you will need this information later.
2. Ensure your instance has a public IP. This will be of form 149.156.x.x. Make note of this IP for later.
3. In the Horizon interface, navigate to DNS -> Zones using the navigation bar on the left.
4. Pick which DNS Zone you would like to use (most projects will only have one DNS zone). To the right of the name, click “Create Record Set”.

5. In the Create Record Set page, fill in the following details:

• Type: A - Address Record
• Name: instance-name.project-code.projects.jetstream-cloud.org.
  • where instance-name should be the name of the instance in all lowercase and with underscores and spaces converted to dashes (e.g. for instance with name 2VERTically-deciding_Jay 2 you would enter 2vertically-deciding-jay-2)
  • where project-code is the code assigned to your allocation/project in all lowercase (For project TRA160003 you would enter tra160003)
  • where the entire string ends in a period.
• Record: Public IP Address currently assigned to the instance (of form 149.156.x.x).
• Leave all other entries with default values.

6. Finally, scroll down and click Submit to finalize the creation of the A record.
