When using Cert-Manager to manage certificates, Note: You may want to have a small range of IP addresses that are addressable on your network, preferably outside the assignment pool allocated by your DHCP server. it creates secrets in your namespaces that can be referenced as TLS secrets in your ingress objects. For Traefik or Let's Encrypt issues, check the logs on your Traefik pod. many examples of Ingresses definitions are located in the test examples of the Traefik repository.

As a result of introducing the custom resource IngressRoutes in traefik 2.0 we don't need to write many annotations on the ingress. To learn more about the various aspects of the Ingress specification that Traefik supports, many examples of Ingresses definitions are located in the test examples of the Traefik repository. Redeploy the sample app using basic auth: Uncomment the following lines in the Ingress resource of azure-vote-app.yaml and apply the changes: Reloading the sample app in the browser should now prompt you for a username and password. as stated in this documentation.
