我跟着http://kubernetes.io/docs/getting-started-guides/docker/。以下是我实际运行的命令：
export K8S_VERSION=$(curl -sS https://storage.googleapis.com/kubernetes-release/release/stable.txt)
export ARCH=amd64
docker run -d \
--volume=/:/rootfs:ro \
--volume=/sys:/sys:rw \
--volume=/var/lib/docker/:/var/lib/docker:rw \
--volume=/var/lib/kubelet/:/var/lib/kubelet:rw \
--volume=/var/run:/var/run:rw \
--net=host \
--pid=host \
--privileged \
gcr.io/google_containers/hyperkube-${ARCH}:${K8S_VERSION} \
/hyperkube kubelet \
--containerized \
--hostname-override=127.0.0.1 \
--api-servers=http://localhost:8080 \
--config=/etc/kubernetes/manifests \
--cluster-dns=10.0.0.10 \
--cluster-domain=cluster.local \
--allow-privileged --v=2
curl -sSL "http://storage.googleapis.com/kubernetes-release/release/v1.2.0/bin/linux/amd64/kubectl" > /usr/bin/kubectl
chmod +x /usr/bin/kubectl
kubectl config set-cluster test-doc --server=http://localhost:8080
kubectl config set-context test-doc --cluster=test-doc
kubectl config use-context test-doc
然后我跟着https://github.com/kubernetes/kubernetes/tree/release-1.2/examples/nodesjs-mongodb：
kubectl create -f web-service.yaml
kubectl create -f web-controller.yaml
kubectl create -f mongo-service.yaml
kubectl create -f mongo-controller.yaml
我有一个Python烧瓶应用程序，所以我用我自己的图像和用['export DOCKER=True && cd commandcenter/ && python app.py']
这是kubectl get services：
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes 10.0.0.1 <none> 443/TCP 3d
mongo 10.0.0.167 <none> 27017/TCP 14m
web 10.0.0.119 80/TCP 6m
kubectl get pods的反叛：

kubectl logs web-controller-6nzpn的结果：

kubectl get nodes的结果：

该机器具有公共IP地址，我的目标是从外部访问演示网站。我可以通过http://public_IP_address:27017和curl 10.0.0.167:27017访问mongo，因为如上所示，mongo有0.0.0.0:27017->27017/tcp。但是，当我运行curl 10.0.0.119:3000时，它就像一个无限的循环，最终它说出来了。那是为什么？
因此，我的问题是：如何公开web以便它还有一个非空的PORTS字段？
我对网络知之甚少，所以非常感谢任何帮助。非常感谢你！

如果查看https://github.com/kubernetes/kubernetes/blob/release-1.2/examples/nodesjs-mongodb/web-service.yaml，您会发现服务类型为LoadBalancer。这旨在与AWS和GCE等云提供商合作。
在您的情况下，您需要使用NodePorts公开服务。指定type: NodePort和nodePort: 3xxxx（某个端口大于30000），您可以<NodeIP>:NodePort访问该服务。
