Seems like you are get the endpointslice for service of nginx-ext. @13567436138

[13567436138]

you are right.My host and member k8s is 1.28.1,will this be a problem?

[liangyuanpeng]

I mean you are already get the endpointslice, it is nginx-ext-jn4xm IPv4 80 10.1.0.244,10.1.2.177,10.1.1.99 3m24s

[liangyuanpeng]

My host and member k8s is 1.28.1,will this be a problem?

I'm using v1.29 for my dev, it's working for me.

both cluster have nginx-ext，the endpointslice is for local cluster
