Short story about swapping bodies as a job; the person who hires the main character misuses his body. Does anyone know what is the ideal way to solve this problem? So you usually It enables the Docker provider and launches a my-app application that allows me to test any request. Traefik communicates with the backend internally in a node via IP addresses. I am using traefik, cert-manager with lets encrypt for using certificates in my application. All major protocols are supported and can be flexibly managed with a rich set of configurable middlewares for load balancing, rate-limiting, circuit-breakers, mirroring, authentication, and more. Problems with that: If the service port defined in the ingress spec is 443 (note that you can still use targetPort to use a different port on your pod). really the case! In this step you will create a Docker network for the proxy to share with containers. Provides a simple HTML frontend of Trfik, A simple endpoint to check for Trfik process liveness. Please refer to https://docs.traefik.io/configuration/commons/, which says: I only managed to expose the Kubernetes Dashboard with setting InsecureSkipVerify = true. ".
