After some planning I am finally in the process of upgrading caddy (binary only) from a pretty old version in order to enable letsencrypt ALPN in stead of SNI challenges for HTTPS certs.
I noticed all certificates are being requested again, while valid certificates are actually present. Digging a little bit I saw a new acme-v02 folder next to the acme-v01 folder for the certificates. So it appears certificates are requested again and stored in this new folder.
Next to the usual sites and users folders, acme-v02 contains a new subfolder challenge_tokens. I’m not entirely sure what the significance is, but it appears to be a temporary folder while renewal is going on.
On first sight it is not possible to copy over the sites and users folders from acme-v01 to acme-v02, as the content fo the files is different.
Anyone has a solution to have this automatic ?
Maybe renewal is not a real issue, it’s not that many certificates. Just wondering if I can avoid renewal (and avoid hitting rate limits bringing the sites down)
At the moment I rolled back to the previous caddy version which still seems to run fine.
