Domain Records

Note: this runs on a cron job and will remove any manually added records. Please read the directions carefully below.

To add a new record:

1. Fork the Repository.
2. Add the record to records.yaml file in the appropriate category. See Sample Record below.
3. Raise a PR.
4. This will be reviewed and merged accordingly.

Sample Record

example.com:
  - name: example.com # Name of the Record
    type: A # Type of the Record
    value: 127.0.0.1 # Value of the Record
    # ttl: "1" # Optional: Time to live.
    # proxied: false # Optional: Whether the record gets Cloudflare's origin protection
    # priority: null # Optional: The priority of the record

Deployment

Please rely on the CICD process in Github Actions.

Implementing in a new Domain

It was not possible to import existing records to tf state and then apply them, this could be fixed in future.

The recommended method for now is as follows:

1. Export current records as a backup from Cloudflare
2. Ensure the terraform state is clean (terraform state list and terraform state rm cloudflare_record.default[...])
3. Get all the id's sh scripts/get-cloudflare-records.sh
4. Delete the records individually sh scripts/delete-cloudflare-records.sh <DNS_RECORD_ID>
5. terraform apply

If anything goes wrong, delete the records and restore the backup via cloudflare.
