I have installed `Kind` for local Kubernetes deployment. I want to make a connection with Jenkins using the kube config file as a secret in Jenkins cloud but getting an error on `Test Connection` `Error testing connection : java.io.IOException: Failed to connect to /127.0.0.1:35439 `

kubectl config view

```auto

but when I view file from this path cat ~.kube/config then getting this file with base64

Due to this connection is not building with Jenkins through the cloud and I’m not able to run the Kubernetes command in the Jenkins File This is my Jenkins Deployment stage

```auto
stage('Deploying App to Kubernetes') {
            steps {
                // Use the kubeconfig credential ID that you added
                withCredentials([file(credentialsId: 'k8s', variable: 'KUBECONFIG')]) {
                    sh 'curl -LO "https://storage.googleapis.com/kubernetes-release/release/v1.20.5/bin/linux/amd64/kubectl"'  
                    sh 'chmod u+x ./kubectl'
                    sh './kubectl config get-contexts'
                    sh './kubectl get nodes'
                    sh './kubectl apply -f deploy/deployment.yaml'
                    sh './kubectl apply -f deploy/service.yaml'
                    sh './kubectl get svc'
                    sh './kubectl get deployments'
                    sh './kubectl get pods'
                }
            }

        }

```

I have a master node with a kind

```auto
kind get clusters
kind

```

```auto
kubectl get nodes
NAME STATUS ROLES AGE VERSION
kind-control-plane Ready control-plane,master 18h v1.21.1

```

```auto
kubectl cluster-info
Kubernetes control plane is running at https://127.0.0.1:35439
CoreDNS is running at https://127.0.0.1:35439/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

```

What could be the issue, I’m not able find the solution and i’m trying this for the last one days and I did not get the proper solution.

You’re trying to connect from a cloud service to something that is only listening on local host. It won’t ever be able to connect.

Thanks, @mrbobbytables for replying to me.  
Can you please give me a solution so that I can resolve this issue?

I want to build a Kubernetes connection with Jenkins

My suggestion would be to use a cloud service. If you want to do it locally you’ll need to have more networking experience.
