Force to update dns

[lukasa1993]

is there any way maybe from admin api to force update services ip ? it seems to be caching it and when i update docker swarm service it takes few minutes to update usually less then 5 but still i would like to update it manually

No. Kong honors the DNS records TTL. There is a setting to override TTL's if you set that to something short, it could alleviate the problem maybe. Otherwise you would have to execute a "reload" to clear the DNS cache.

      - KONG_DNS_STALE_TTL=120      
      - KONG_DNS_ORDER=A      
      - KONG_DNS_NOT_FOUND_TTL=1      
      - KONG_DNS_NO_SYNC=on

this is what i use what is "reload" ? and how to execute it ?
