As I see, a server asks for a new certificate every Caddy reload (certainly when I use a Docker container and reload it). At the end you get the error “too many certificates already issued for exact set of domains”.
I know, that for a staging and development purpose you can use this config: acme_ca "https://acme-staging-v02.api.letsencrypt.org/directory". But sometimes I have many changing in production server and I can’t use this solution.
Is here the way how to cache a certificate and not reissue it every Docker container reload?
Yes, persist the /data volume. It’s explained in the docs on Docker Hub: Docker Hub
Thank you very much!
