我有一个如下所示的 pod 文件:
apiVersion: v1
kind: Pod
metadata:
name: test-api
labels:
app: web
spec:
containers:
- name: test-api-container
image: cmgvieira/test-api:latest
imagePullSecrets:
- name: regsecret
运行正常:
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
test-api 1/1 Running 0 10d
我可以使用kubectl port-forward test-api 3000:80
then 来访问它wget localhost:3000
。
当我使用公开它时kubectl expose -f test-api-pod.yml --port=80 --target-port=80 --type=LoadBalancer
,服务已成功创建:
$ kubectl describe service test-api
Name: test-api
Namespace: default
Labels: app=web
Selector: app=web
Type: LoadBalancer
IP: 100.XXX.XXX.XXX
LoadBalancer Ingress: XYZ-ABC.us-east-1.elb.amazonaws.com
Port: <unset> 80/TCP
NodePort: <unset> 32310/TCP
Endpoints: <none>
Session Affinity: None
Events:
FirstSeen LastSeen Count From SubObjectPath Type Reason Message
--------- -------- ----- ---- ------------- -------- ------ -------
7m 7m 1 {service-controller } Normal CreatingLoadBalancer Creating load balancer
7m 7m 1 {service-controller } Normal CreatedLoadBalancer Created load balancer
但我无法访问,wget XYZ-ABC.us-east-1.elb.amazonaws.com
因为超时了。
我认为这可能是主机名的问题,因此我将 XYZ-ABC.us-east-1.elb.amazonaws.com 添加到我的本地“hosts”文件中,使其解析为127.0.0.1
,并且服务器响应正常。
有谁知道是什么原因导致了这个问题?
另请注意,当我使用常规nginx
图像而不是我自己的应用服务器时,两者都port-forward
可以expose
正常工作。
仅供参考:
$ kubectl version
