With general availability of the [“shortlived” profile](https://letsencrypt.org/docs/profiles/#shortlived) [coming up at LetsEncrypt this week](https://community.letsencrypt.org/t/upcoming-changes-to-let-s-encrypt-certificates/243873), I wonder if Traefik already supports ARI?

If it doesn’t, is it planned? I assume in this case I’d need to use the [acme.certificatesDuration](https://doc.traefik.io/traefik/reference/install-configuration/tls/certificate-resolvers/acme/#opt-acme-certificatesDuration) config to shorten lifetime and implicitely renewal period?

Traefik uses [go-acme library](https://github.com/go-acme/lego), updates usually take some weeks to be integrated into Traefik.

I’m not sure if I understand what you answered. Go-acme has supported ACME ARI since May 2023 (see [PR](https://github.com/go-acme/lego/pull/1912)). Does that mean that Traefik supports ARI since 2023 as well?

Then I would expect Traefik to support it. Have you tried it?

How would I try? The documentation doesn’t state anything about ARI.

However, I’d expect Traefik to persist renewal info somewhere (at least a timestamp and/or a renewal ID), but in acme.json there is nothing.

It seems that Traefik should implement support for ACME Renewal Information.

This would be helpful for [v3.7.0-rc.1: all certs are marked with warning in new certificate dashboard · Issue #12946 · traefik/traefik · GitHub](https://github.com/traefik/traefik/issues/12946) and most importantly [Provide better renew period/interval for new LetsEncrypt shortlived (160h) certs · Issue #12461 · traefik/traefik · GitHub](https://github.com/traefik/traefik/issues/12461)
