Hi,
I have done the polaris installation and followed all the steps mentioned.
Used dig command to check the desire output and I think I am getting proper result.
But after that there is nothing in the documentation what to do. I have setup a DNS and trying to open with http but it is not giving the expected output.
Please find below the steps I have done:
- Setup the Polaris GSLB. Below is the polaris-lb.yaml configuration:
pools:
www-gslbpoc:
monitor: http
monitor_params:
use_ssl: false
hostname: myservice.gslbpoc.com
url_path: /gslb/health
port: 8080
expected_codes:
- 200
lb_method: wrr
fallback: any
members:
- ip: 10.247.10.1
name: www1-dc1
weight: 1
- ip: 10.247.20.1
name: www2-dc2
weight: 1
globalnames:
myservice.gslbpoc.com:
pool: www-gslbpoc
ttl: 1

Ran it multiple time and got both the ips in the output.
