How to configure default tls certificate on kubernetes?

traefik version 2.2.0 running on Kubernetes.
When a request to my traefik without SNI, which display the traefik default certificate, but it is untrusted by the browser.
There is no example about how to configure default tls on Kubernetes, any guys could share with me how to?

OK, it works. :grinning: I had done the following
traefik deployments add follow args


# Dynamic configuration
      certFile = "/ssl/xxx.pem"
      keyFile  = "/ssl/xxx.key"
    minVersion = "VersionTLS10"
    minVersion = "VersionTLS13"
