Go创建k8s配置文件yaml

首先安装 goctl 工具

goctl kube deploy -name nginx -namespace test -image nginx:alpine -o nginx-test.yaml -port 80

生成的 yaml 文件如下:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx
  namespace: test
  labels:
    app: nginx

  replicas: 3

          limits:

          mountPath: /etc/localtime
      volumes:
