I wanna using traefik auto discovery kubernetes service. The docker-compose.yaml is like this:

version: "3.3"

services:

  traefik:
    image: "traefik:v2.5"
   version: "3.3"

services:

  whoami:
    image: "traefik/whoami"
    container_name: "simple-service"
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.rule=Host(`whoami.com`)"
      - "traefik.http.routers.whoami.entrypoints=web"

And run docker-compose up -d is working,the whoami.com discoveried.

But when I convert this to kubernetes yaml,I got error with labels, How can I write the labels on kubernetes yaml.

labels:
  - "traefik.enable=true"
  - "traefik.http.routers.whoami.rule=Host(`whoami.com`)" 
  -  "traefik.http.routers.whoami.entrypoints=web"
