Jenkins 部署文件的问题:未知的资源类型:部署

Question

我正在努力弄清楚解决方案可能是什么，所以我想在这里问。我正在尝试使用以下代码将 Jenkins pod 部署到 Kubernetes，但它因未知资源类型而失败： 部署错误：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: jenkins-deployment
spec:
replicas: 1
selector:
matchLabels:
app: jenkins
template:
metadata:
labels:
app: jenkins
spec:
containers:
- name: jenkins
image: jenkins/jenkins:lts-alpine
ports:
- name: http-port
containerPort: 8080
volumeMounts:
- name: jenkins-home
mountPath: /var/jenkins_home
volumes:
- name: jenkins-home
emptyDir: {}

kubectl api-versions的输出为：

admissionregistration.k8s.io/v1
admissionregistration.k8s.io/v1beta1
apiextensions.k8s.io/v1
apiextensions.k8s.io/v1beta1

scheduling.k8s.io/v1
scheduling.k8s.io/v1beta1
storage.k8s.io/v1
storage.k8s.io/v1beta1
v1

有谁知道问题可能是什么？ 如果这是一个缩进问题，我看不到它。

Answer 1

似乎apiVersion已被弃用。您可以简单地转换为当前apiVersion并申请。

$ kubectl convert -f jenkins-dep.yml          
kubectl convert is DEPRECATED and will be removed in a future version.
In order to convert, kubectl apply the object to the cluster, then kubectl get at the desired version.
apiVersion: apps/v1

$ kubectl convert -f jenkins-dep.yml -oyaml > jenkins-dep-latest.yml

将apiVersion从extensions/v1beta1更改为apps/v1，并使用kubectl version检查 kubectl 客户端和 kube API 服务器版本是否匹配并且不是太旧。
