我正在尝试学习如何在Minikube中使用Kibernetes,并具有以下部署和服务:
I am trying to learn how to use Kibernetes with Minikube and have the following deployment and service:
--- kind: Service apiVersion: v1 metadata: name: exampleservice spec: selector: app: myapp ports: - protocol: "TCP" # Port accessible inside cluster port: 8081 # Port to forward to inside the pod targetPort: 8080 # Port accessible outside cluster nodePort: 30002 type: LoadBalancer --- apiVersion: extensions/v1beta1 kind: Deployment metadata: name: myappdeployment spec: replicas: 5 template: metadata: labels: app: myapp spec: containers: - name: myapp image: tutum/hello-world ports: - containerPort: 8080我希望能够从本地计算机
I expect to be able to hit this service from my local machine at
192.168.64.2:30002按照以下命令: minikube service exampleservice --url ,但是当我尝试从浏览器访问它时,我得到的网站无法访问.
As per the command: minikube service exampleservice --url but when I try to access this from the browser I get a site cannot be reached error.
一些有助于调试的信息:
Some information that may help debugging:
kubectl get services --all-namespaces :
NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE default exampleservice LoadBalancer 10.104.248.158 <pending> 8081:30002/TCP 26m default kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 2h default user-service-service LoadBalancer 10.110.181.202 <pending> 8080:30001/TCP 42m kube-system kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 2h kube-system kubernetes-dashboard ClusterIP 10.110.65.24 <none> 80/TCP 2h我正在OSX上运行minikube.
I am running minikube on OSX.
推荐答案这是预期的.请注意,LoadBalancer是用于云的,用于在AWS中创建外部负载均衡器(例如ALP/NLP),并在GCP/Azure中创建类似的负载均衡器.
This is expected. Do note that LoadBalancer is for cloud to create external load balancer like ALP/NLP in AWS and something similar in GCP/Azure etc.
如此处所示更新服务.在这里,我假设 192.168.64.2 是您的minikube ip.如果没有,请使用minikube ip对其进行更新以使其正常工作.
Update the service as shown here. here i assume 192.168.64.2 is your minikube ip. if not, update it with minikube ip to make it work.
kind: Service apiVersion: v1 metadata: name: exampleservice spec: selector: app: myapp ports: - protocol: "TCP" # Port accessible inside cluster port: 8081 # Port to forward to inside the pod targetPort: 80 # Port accessible outside cluster nodePort: 30002 type: LoadBalancer externalIPs: - 192.168.64.2现在,您可以通过 192.168.64.2:8081/
如果您需要通过30002访问该应用程序,则可以像这样使用它
If you need to access the application at 30002, you can use it like this
kind: Service apiVersion: v1 metadata: name: exampleservice spec: selector: app: myapp ports: - protocol: "TCP" # Port accessible inside cluster port: 8081 # Port to forward to inside the pod targetPort: 80 # Port accessible outside cluster nodePort: 30002 type: NodePort您的部署文件对我来说似乎不正确.
Your deployment file does not look correct to me.
删除它 kubectl删除deploy/myappdeployment
使用它再次创建.
apiVersion: apps/v1beta1 kind: Deployment metadata: labels: app: myapp name: myappdeployment spec: replicas: 5 selector: matchLabels: app: myapp strategy: {} template: metadata: labels: app: myapp spec: containers: - image: tutum/hello-world name: myapp ports: - containerPort: 80更多推荐
从主机访问Minikube负载均衡器服务
