Hi Jay,
I tried the native k8s commands (in a fresh bay):
*kubectl create -s http://192.168.1.249:8080 <http://192.168.1.249:8080> -f
./redis-master.yaml*
*kubectl create -s http://192.168.1.249:8080 <http://192.168.1.249:8080> -f
./redis-sentinel-service.yaml*
*kubectl create -s http://192.168.1.249:8080 <http://192.168.1.249:8080> -f
./redis-controller.yaml*
*kubectl create -s http://192.168.1.249:8080 <http://192.168.1.249:8080> -f
./redis-sentinel-controller.yaml*
It still didn't work (same symptom as before). I cannot spot any difference
between the original yaml file and the parsed yam file. Any other idea?
Thanks,
Hongbin
