1. Enable Healthcheck with CLI & Ping, Docker HEALTHCHECK, and Secure Dashboard/API

1. Before we begin, lets cleanup any running Docker stack docker stack rm traefik If you named you stack something else use your specified name. If you don't remember run docker stack ls
2. Change to the 07-Operations folder
3. Open the traefik.yml file in your favorite editor and review the Traefik API, Dashboard & Ping sections section
4. In the API section Change insecure from true to false which is default

api:
  # Dashboard
  # true = default
  # 
  dashboard: true
  #
  # insecure: false is default
  #
  insecure: false

5. Review the docker HEALTHCHECK in docker-compose.cli.yml

healthcheck:
      test: ["CMD", "traefik", "healthcheck"]
      interval: 10s
      timeout: 2s
      retries: 3
      start_period: 5s

6. Start Traefik with Ping endpoint, Secure Mode ,and Docker HEALTHCHECK -> docker stack deploy -c docker-compose.cli.yml traefik
7. Run docker ps notice the traefik container status now has Health status
8. Open the Ping endpoint http://your_domain_here/ping
9. Make an API request http://your_domain_here:8080/api/http/routers
10. Open the Dashboard. Ensure to have the trailing "/" http://your_domain_here/dashboard/
