Hi all,
This is my pipeline
pipeline {
agent {
kubernetes {
yamlFile 'Jenkins-agent-pod.yaml'
}
}
environment {
DOCKERFILE_PATH = 'Dockerfile'
DOCKER_IMAGE_NAME = 'myrepo/myapp:tag'
}
stages {
stage('Build and Push Docker Image with Kaniko') {
steps {
container(name: 'kaniko', shell: '/busybox/sh') {
withCredentials([file(credentialsId: 'dockerhub', variable: 'DOCKER_CONFIG_JSON')]) {
withEnv(['PATH+EXTRA=/busybox']) {
sh '''#!/busybox/sh
cp $DOCKER_CONFIG_JSON /kaniko/.docker/config.json
/kaniko/executor --context `pwd` --dockerfile $DOCKERFILE_PATH --destination $DOCKER_IMAGE_NAME
'''
}
}
}
}
}
stage('Deploy App to Kubernetes') {
steps {
container('kubectl') {
withCredentials([file(credentialsId: 'k3s-hq-admin', variable: 'KUBECONFIG')]) {
sh 'kubectl get nodes'
}
}
}
}
}
}

The credentialsId: 'k3s-hq-admin' is the same jenkins credential for connecting jenkins with k8s cluster.
How can I troubleshoot it ? Please give me some advice, thank you very much.
