Traefik

Strip Prefix

Let’s assume you have a URL “https://whoami.your.domain.de/removeme" and you wanna get rid of the “removeme” before passing the Request to the Webserver. Stripprefix is your friend …

docker-compose.yml

  whoami:
    image: containous/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.middlewares.test-stripprefix.stripprefix.prefixes=/wegdamit,/removeme"
      - "traefik.http.routers.whoami.middlewares=test-stripprefix@docker"
      - "traefik.http.routers.whoami.rule=Host(`whoami.your.domain.de`)"
      - "traefik.http.routers.whoami.tls.certresolver=letsencrypt"
      - "traefik.http.routers.whoami.tls=true"

Any Comments ?

docker-compose.yml

let’s limit the Requests to 10 Req / 10 Seconds.

  whoami:
    image: containous/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.middlewares.test-ratelimit.ratelimit.average=10"
      - "traefik.http.middlewares.test-ratelimit.ratelimit.burst=0"
      - "traefik.http.middlewares.test-ratelimit.ratelimit.period=10s"
      - "traefik.http.routers.whoami.middlewares=test-ratelimit@docker"
      - "traefik.http.routers.whoami.rule=Host(`whoami.your.domain.de`)"
      - "traefik.http.routers.whoami.tls.certresolver=letsencrypt"
      - "traefik.http.routers.whoami.tls=true"

restart container

docker compose -f docker-compose.yml up -d
