使用hashicorp / consul-k8s：0.11.0进行syncCatalog：

我已经按照掌舵表中的描述尝试了默认试用：https://github.com/hashicorp/consul-helm
唯一的区别是我使用的是ClusterIP和Ingress，它们与Pod的运行状况无关。
有什么想法吗？
当将k8s入口与ClusterIP一起使用时，应将领事地址设置为入口主机，因为它实际上是暴露的，没有端口。这意味着k8s部署的相应部分应如下所示：
Liveness: http-get http://:8080/health/ready delay=30s timeout=5s period=5s #success=1 #failure=3
Readiness: http-get http://:8080/health/ready delay=10s timeout=5s period=5s #success=1 #failure=5
Environment:
HOST_IP: (v1:status.hostIP)
NAMESPACE: (v1:metadata.namespace)
CONSUL_HTTP_ADDR: http://{INGRESS HOST}
