为什么我不能通过端口转发器连接到 pods？

Question

更新：

通过安装 socat 解决了这个问题 -

   sudo apt-get -y install socat

我正在尝试通过端口转发器从另一个终端连接到 minikube 中的 pod I 运行，但出现一些错误。

我的kubectl版本-

Client Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.3", GitCommit:"2d3c76f9091b6bec110a5e63777c332469e0cba2", GitTreeState:"clean", BuildDate:"2019-08-19T11:13:54Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}

Server Version: version.Info{Major:"1", Minor:"15", GitVersion:"v1.15.2", GitCommit:"f6278300bebbb750328ac16ee6dd3aa7d3549568", GitTreeState:"clean", BuildDate:"2019-08-05T09:15:22Z", GoVersion:"go1.12.5", Compiler:"gc", Platform:"linux/amd64"}

YML文件内容-

apiVersion: v1
kind: Pod
metadata:
  name: kubia-manual
spec:
  containers:
  - image: luksa/kubia
    name: kubia
    ports:
    - containerPort: 8080
      protocol: TCP

我运行-

kubectl create -f kubia-manual.yaml

kubectl port-forward kubia-manual 8888:8080

得到了-

Forwarding from 127.0.0.1:8888 -> 8080

Forwarding from [::1]:8888 -> 8080

在我尝试从另一个终端连接到 pod 之后 -

curl localhost:8888

我进入这个终端

curl: (52) Empty reply from server

在第二个终端中，我运行我得到的端口转发命令 -

Handling connection for 8888 E1020 14:55:35.817708 7075 portforward.go:400] an error occurred forwarding 8888 -> 8080: error forwarding port 8080 to pod 253ecb3809333d7dbf7c54831ea12e1eee4f43c3107764ea8ad55f0cad06bc2c, uid : unable to do port forwarding: socat not found.

Answer 1

我认为根据您的端口转发，您应该尝试在 8888 上连接它

 curl localhost:8888

对我有用

Answer 2

最后安装socat解决了 -

   sudo apt-get -y install socat

为什么我不能通过端口转发器连接到 pods？

Why can't I connect to pods through the port-forwarder?

portforwarding

kubernetes

kubectl

minikube
