Support for ACME ARI (Renewal Information)?

Traefik Traefik v3 (latest)

With general availability of the “shortlived” profile coming up at LetsEncrypt this week, 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 config to shorten lifetime and implicitely renewal period?

Traefik uses go-acme library, 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). Does that mean that Traefik supports ARI since 2023 as well?

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

5

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 and most importantly Provide better renew period/interval for new LetsEncrypt shortlived (160h) certs · Issue #12461 · traefik/traefik · GitHub
