Kubernetes IngressRoute with TLS secret

Traefik Traefik v2
1

So this ingress configuration fails and I get a certificate with a Traefik Default as a CN in the frontend despite providing the TLS data in a secret.

The cert and key were generated using openssl and the data copied from there:

openssl req -newkey rsa:2048 -nodes -keyout tls.key -x509 -days 3650 -out tls.crt

The route is reachable but not with the provided certificate. I suspect because Traefik has this error and then uses the default cert:

Unable to append certificate <cert-data> to store: unable to generate TLS certificate : tls: failed to find any PEM data in certificate input" tlsStoreName=default

Perhaps I'm missing or misunderstanding something.

Hello @yassine.laz,

When you created the certificate tls.key and tls.crt files on your local machine, you stated that you used:

can you confirm that you did this by creating the secret from the files using the following command?

kubectl -n velero create secret tls minio-tls --key=tls.key --cert=tls.crt

That solves it, Not sure why setting the data directly in secret's yaml wont.
