如何在为“Kube.netes”使用“Kubeadm”时通过“Skaffold”使用本地集群？

Question

我正在尝试使用skaffold在本地 Kube.netes 集群上部署我的 NodeJS 应用程序，但我得到以下结果：

DEBU[0018] Pod "expiration-depl-7989dc5ff4-lkpvw" scheduled but not ready: checking container statuses  subtask=-1 task=DevLoop

Answer 1

首先，您使用的是什么“本地 Kube.netes”？

在 skaffold.yaml 的部署部分，您需要指定要用于部署的 k8s 上下文，如下所示：

    deploy:
      kubeContext: minikube

要检查您的机器类型上可用的 k8s 上下文：

kubectl config get-contexts
