[Query] Can certificates be read from one nested directory: something like test/*/a.pem

[porwalameet]

Hi,

We have a requirement to read certificates within a directory with one level down.

Something like this:
/etc/containerd/certs.d/abc/a.pem
/etc/containerd/certs.d/def/b.pem
/etc/containerd/certs.d/xyz/z.crt

here there is no fixed naming convention for abc, def or xyz, so i prefer to give wildcard.

So, I have configured something like below:
watchDirectories:
- /etc/containerd/certs.d/
watchSpecificExtensionDirectories:
- pem
- crt

It doesnt try to match the directory within certs.d.
The error is caught during startup:
time="2025-08-05T12:13:52Z" level=warning msg="failed to parse \"/mnt/watch/dir-a59898a81f4333a329d7ab95040dc315f7e06241eb08d01876//etc/containerd/certs.d\": no directory match \"/mnt/watch/dir-a59898a81f4333a329d7ab95040dc315f7e06241eb08d01876//etc/containerd/certs.d\""

Can you please clarify is this supported, and this config is correct?
