在Kubernetes v1.3.6中使用run来测试Nginx容器时出现弃用错误

Question

尝试运行几个Nginx Pod时出现过时错误

bash-4.4$ kubectl run nginx --image=nginx --port=80 --replicas=3
WARNING: New generator "deployment/apps.v1beta1" specified, but it isn't available. Falling back to "deployment/v1beta1".
kubectl run --generator=deployment/apps.v1beta1 is DEPRECATED and will be removed in a future version. Use kubectl create instead.
error: no matches for kind "Deployment" in version "apps/v1beta1"

在尝试添加应用程序生成器时，我也遇到了麻烦...

bash-4.4$ kubectl run nginx --image=nginx --port=80 --replicas=3 --generator=deployment/apps.v1beta1
kubectl run --generator=deployment/apps.v1beta1 is DEPRECATED and will be removed in a future version. Use kubectl create instead.
error: no matches for kind "Deployment" in version "apps/v1beta1"

不太确定发生了什么，我只是在尝试一个简单的世界，这里是部署和公开的剧本

---
#######################################
# Deploy and expose Nginx service
#######################################

# Expects kubectl being configured on the local machine
# using kubectl.yml playbook

- hosts: localhost
  connection: local

  tasks:

  - name: Launch 3 nginx pods
    command: "kubectl run nginx --image=nginx --port=80 --replicas=3"
    # command: "kubectl create deployment nginx --image=nginx --generator=deployment-basic/v1beta1"

  - name: Expose nginx
    command: "kubectl expose deployment nginx --type NodePort"

  - name: Get exposed port
    command: "kubectl get svc nginx --output=jsonpath='{range .spec.ports[0]}{.nodePort}'"
    register: result
  - set_fact:
      node_port: "{{ result.stdout }}"

  - debug: msg="Exposed port {{ node_port }}"

这是集群和版本等的一些背景

bash-4.4$ kubectl version

bash-4.4$ kubectl get  componentstatus

非常感谢您的帮助，我在黑客马拉松中举起了一些家伙；）

您在kubectl和Kubernetes集群版本上kubectl很大的不匹配（1.12.2与1.3.6）。 我建议您下载kubectl 1.3.6。 如果您使用的是Linux：

$ wget https://dl.k8s.io/v1.3.6/kubernetes-client-linux-amd64.tar.gz
$ tar zxvf kubernetes-client-linux-amd64.tar.gz

或MacOS：

$ wget https://dl.k8s.io/v1.3.6/kubernetes-client-darwin-amd64.tar.gz
$ tar zxvf kubernetes-client-darwin-amd64.tar.gz
