Is there a way to get/add/modify DNS records in Digital Ocean via doctl or another command line utility? I was unable to find anything that looked relevant via doctl help.

It looks like worst case I could call the HTTP API directly, although I’m not sure how I would need to get the correct authentication credentials.

curl 'https://cloud.digitalocean.com/api/v1/domains/MY_DOMAIN/records/MY_RECORD' -X PUT
...
-H 'Cookie: ... _digitalocean2_session_v4=SOME_AUTH_TOKEN?; ...'
--data-raw '{"record":{"name":"_dnslink.www.MY_DOMAIN","record_type":"TXT","created_at":"2020-08-30T22:39:51.000Z","updated_at":"2020-09-24T03:55:21.000Z","port":null,"weight":null,"ttl":"300","data_record":"dnslink=/ipfs/IPFS_HASH","priority":null,"tag":null,"flags":null,"droplet_id":null,"floating_ip_id":null,"load_balancer_id":null}}'

My use case is I have a GitHub Action that uploads a web app to IPFS (https://ipfs.io/) that is served via a dnslink.DOMAIN TXT record via CloudFlare (https://medium.com/pinata/how-to-easily-host-a-website-on-ipfs-9d842b5d6a01, section Setting Up Your DNS Records to Point to Cloudflare). After the upload happens, I need to update that _dnslink record to point to the new IPFS hash (dnslink.DOMAIN TXT “dnslink=/ipfs/IPFS_HASH”)

Action yml (modified for clarity) in case it helps:
