I have 3 instances of Hashicorp Vault and the leader is tagged as 'active' while the other 2 are tagged as 'standby' in Consul. I'd like to set Traefik to route requests for vault's admin portal ui to the leader (the one tagged 'active'). With Fabio I just set a rule "weight 1 tags 'active'" but I can't find an equivalent for Traefik.
Can anyone suggest how I would achieve this?
