HAProxy - HA-Proxy version 2.0.14-1ppa1~bionic 2020/04/16
Setting up HAProxy for the first time. It has gone swimmingly and works well. However I would like to resolve the backends by DNS for simplicity in our environment. I have tried to set up the resolvers section and heres the weird thing. It works GREAT! For about 10 seconds. When I restart haproxy everything come up and it all works excellent. It routes to where I need to go and everything. Then after about that first 10 seconds or so it shows as Maintenance on the stats page and the error says:
haproxy: [WARNING] 106/161936 (3274) : Server bobserver/bobs-server is going DOWN for maintenance (unspecified DNS error). 0 active and 0 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
My config is:
nameserver bobs-dns-server 10.0.xxx.xxx:53
hold valid 10s
timeout resolve 1s
timeout retry 1s
hold other 30s
hold refused 30s
hold nx 30s
hold timeout 30s
hold obsolete 30s
You can also see that I have the #parse-resolv-conf commented out because I wanted to use that, but I am getting the same result. I know the DNS works, I know it continues to work. The server IP’s dont change (its on-prem servers). I can hard code the IP’s but really dont want to.
Any help would be great!
