title: How to configure Traefik Sticy Session in Kubernetes
body: <p>I am merging my applications from <code>docker</code> to <code>kubernetes</code>.</p>
  <p>I am currently working with <code>minikube</code>.</p>
  <p>I am using traefik as my reverse proxy, and it was installed in kubernetes using the oficial <code>helm chart</code> available at <a href="https://github.com/traefik/traefik-helm-chart" rel="nofollow noreferrer">https://github.com/traefik/traefik-helm-chart</a>.</p>
  <p>Here is my working docker-compose file:</p>
  <pre class="lang-yaml prettyprint-override"><code>version: &quot;3.7&quot;
  services:
    myapp:
      image: nexus/my-app
      labels:
        - &quot;traefik.enable=true&quot;
        - &quot;traefik.http.routers.myapp.rule=Host(`myapp.localhost`)&quot;
        - &quot;traefik.http.routers.myapp.entrypoints=web,web-secure&quot;
        - &quot;traefik.http.routers.myapp.tls=true&quot;
        - &quot;traefik.http.routers.myapp.service=myapp&quot;
        - &quot;traefik.http.middlewares.myapp.redirectscheme.scheme=https&quot;
        - &quot;traefik.http.middlewares.myapp.redirectscheme.permanent=true&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.server.port=8080&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.sticky=true&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.sticky.cookie.name=StickyCookieMyApp&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.sticky.cookie.secure=true&quot;
        # enable the property below if your are running on https
        - &quot;traefik.http.services.myapp.loadbalancer.server.scheme=https&quot;      
      environment:
        - JAVA_OPTS=-Xmx512m -Xms256m
        - SPRING_PROFILES_ACTIVE=prod
  </code></pre>
  <p>In Kubernetes I have the following configuration that is working:</p>
  <pre class="lang-yaml prettyprint-override"><code># HTTPS ingress
  kind: Ingress
  apiVersion: extensions/v1beta1
  metadata:
    name: myapp-ingress
    annotations:
      traefik.ingress.kubernetes.io/router.entrypoints: websecure
      traefik.ingress.kubernetes.io/router.tls: &quot;true&quot;
  spec:
    rules:
      - host: myapp.localhost
        http:
          paths:
            - backend:
                serviceName: myapp
                servicePort: 8080
    tls:
      - secretName: myapp-cert
  ---
  # Ingresses
  # this middleware is used as the following annotation:
  # traefik.ingress.kubernetes.io/router.middlewares: default-redirect@kubernetescrd
  apiVersion: traefik.containo.us/v1alpha1
  kind: Middleware
  metadata:
    name: redirect
  spec:
    redirectScheme:
      scheme: https
      permanent: true
  ---
  # http ingress for http-&gt;https redirection
  kind: Ingress
  apiVersion: extensions/v1beta1
  metadata:
    name: myapp-redirect
    annotations:
      traefik.ingress.kubernetes.io/router.middlewares: default-redirect@kubernetescrd
      traefik.ingress.kubernetes.io/router.entrypoints: web
  spec:
    rules:
      - host: myapp.localhost
        http:
          paths:
            - backend:
                serviceName: myapp
                servicePort: 8080
  </code></pre>
  <p>How do I transform these three lines into Kubernetes spec?</p>
  <pre class="lang-yaml prettyprint-override"><code>      - &quot;traefik.http.services.myapp.loadbalancer.sticky=true&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.sticky.cookie.name=StickyCookieMyApp&quot;
        - &quot;traefik.http.services.myapp.loadbalancer.sticky.cookie.secure=true&quot;
  </code></pre>
