I want to use my consul k/v store to save the tls certificates. I have found this plugin GitHub - pteich/caddy-tlsconsul: 🔒 Consul K/V storage for Caddy Web Server / Certmagic TLS data but it seems, that it is not ready for caddy v2. Does anyone know, if there is some ongoing development? Otherwise I would give it a try to make it compatible.
Indeed, looks like it hasn’t been ported to v2 yet.
These are very easy to do, though! You can look at Make Caddy-compatible storage module by mholt · Pull Request #3 · silinternational/certmagic-storage-dynamodb · GitHub to see how I updated the DynamoDB plugin for v2. Good luck! 
Let me know if you have any questions.
I think the port was successful. Will doing some more tests and cleanup tomorrow and then trying to make a PR at the repository.
