在 kubernetes 中挂载 hostPath 的问题
Issues mounting hostPath in kubernetes
好的,我正在尝试在 kubernetes 的 minikube 中设置 Jenkins 容器的本地版本,我使用 this guide 作为模型。
我遇到的问题是 hostPath 似乎没有正确安装。
当我尝试不使用 "persistentVolumeClaim" 挂载主机路径时
我的代码如下所示:
deployment_jenkins.yaml
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: jenkins
namespace: jenkins
spec:
replicas: 1
template:
metadata:
labels:
app: master
spec:
containers:
- name: master
image: jenkins:2.7.2
ports:
- containerPort: 8080
- containerPort: 50000
readinessProbe:
httpGet:
path: /login
port: 8080
periodSeconds: 10
timeoutSeconds: 5
successThreshold: 2
failureThreshold: 5
env:
- name: JENKINS_OPTS
valueFrom:
secretKeyRef:
name: jenkins
key: options
volumeMounts:
- mountPath: /var/jenkins_home
name: jenkins-home
resources:
limits:
cpu: 500m
memory: 1500Mi
requests:
cpu: 500m
memory: 1500Mi
volumes:
- name: jenkins-home
hostPath:
path: /data
当我 运行 kubectl apply-f deployment_jenkins.yaml:
时出现这个错误
my-mac kubernetes $ kubectl apply -f deployment_jenkins.yaml
error: error validating "deployment_jenkins.yaml": error validating data:
found invalid field hostPath for v1.PodSpec; if you choose to ignore these
errors, turn validation off with --validate=false
然后当我尝试使用声明时,我得到了这个:
persistent_volume_claim_jenkins.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: jenkins-home-claim
spec:
accessModes:

然后我 运行 命令:
my-mac kubernetes $ kubectl apply -f .
deployment "jenkins" configured
persistentvolumeclaim "jenkins-home-claim" configured
persistentvolume "jenkins-home" configured
最终,我的 pod 从未启动,我在仪表板中收到以下错误:
我非常困惑,如果能帮助我找出我做错了什么以及如何让它发挥作用,我们将不胜感激。
您的一些 yaml 缩进错误导致不同的(损坏的)解释:
volumes:
- name: jenkins-home
hostPath:
path: /data
这是一个包含两个字段的对象,volumes
和 hostPath
。相反,您想要的是:
volumes:
- name: jenkins-home
hostPath:
path: /data
此外,我建议始终在您的 yaml 中引用(非块)字符串以避免意外:
volumes:
- name: 'jenkins-home'
hostPath:
path: '/data'
