add theses labels in traefik
- "traefik.http.services.whoami.loadbalancer.sticky.cookie=true"
- "traefik.http.services.whoami.loadBalancer.sticky.cookie.name=sticky"
if you call that url
curl -s 'https://whoami.raphaelpiccolo.com/'
you get a cookie :
Cookie: sticky=http://172.18.0.79:80
if we send it in next requests we land on the same container
curl -s -b "sticky=http://172.18.0.79:80" 'https://whoami.raphaelpiccolo.com/'
