Hello all,

I am try to run this sample but I got those error when access the ribbon service in kubernetes:

kubectl get services:
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
hello-hystrix 10.0.0.162 80:32210/TCP 6m
hello-ribbon 10.0.0.26 80:32199/TCP 6m
kubernetes 10.0.0.1 443/TCP 7m

Url: http://192.168.99.100:32199/hello

if I try access br hello-kystrix services its works fine.

I tryed google about those error, but I got no response.

Someone has any idea about what those error??

Thanks,

HTTP ERROR 503
