kubernetes部署jenkins

参考：kubernetes 部署 Jenkins jenkins kubernetes pipeline_mob64ca14116c53的技术博客_51CTO博客

第七篇：kubernetes部署jenkins-CSDN博客

1、当前kubernetes集群已部署nfs服务

showmount -e

创建jenkins目录

2、添加jenkins的pvc

kubectl create namespace jenkins-k8s

cd /opt/dockerfile/jenkins/

touch jenkins-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:name: jenkins-k8s-pv
spec:capacity:storage: 10GiaccessModes:- ReadWriteManynfs:server: 192.168.1.247path: /opt/nfsdata/jenkins

touch jeckins-pvc.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:name: jenkins-k8s-pvcnamespace: jenkins-k8s
spec:resources:requests:storage: 10GiaccessModes:- ReadWriteMany

kubectl get pv -n jenkins-k8s

 创建一个sa账号,做rbac授权

kubectl create sa jenkins-k8s-sa -n jenkins-k8s

kubectl create clusterrolebinding jenkins-k8s-sa-cluster -n jenkins-k8s  --clusterrole=cluster-admin --serviceaccount=jenkins-k8s:jenkins-k8s-sa

2、部署 jenkins

kubectl apply -f jeckins-deploy.yaml

kind: Deployment
apiVersion: apps/v1
metadata:name: jenkinsnamespace: jenkins-k8s
spec:replicas: 1selector:matchLabels:app: jenkinstemplate:metadata:labels:app: jenkinsspec:serviceAccount: jenkins-k8s-sacontainers:- name: jenkinsimage: jenkins/jenkins:ltsimagePullPolicy: IfNotPresentports:- containerPort: 8080name: webprotocol: TCP- containerPort: 50000name: agentprotocol: TCPresources:limits:cpu: 1000mmemory: 1Girequests:cpu: 500mmemory: 512MilivenessProbe:httpGet:path: /loginport: 8080initialDelaySeconds: 60timeoutSeconds: 5failureThreshold: 12readinessProbe:httpGet:path: /loginport: 8080initialDelaySeconds: 60timeoutSeconds: 5failureThreshold: 12volumeMounts:- name: jenkins-volumesubPath: jenkins-homemountPath: /var/jenkins_homevolumes:- name: jenkins-volumepersistentVolumeClaim:claimName: jenkins-k8s-pvc

kubectl apply -f jeckins-deploy.yaml

kubectl describe pod jenkins-74bb6797d9-qd92c -n jenkins-k8s
 

kubectl logs pod jenkins-74bb6797d9-qd92c -c jenkins -n jenkins-k8s
没权限

chown -R 1000:1000 /opt/nfsdata/jenkins

kubectl delete -f jeckins-deploy.yaml

重装

kubectl apply -f jeckins-deploy.yaml

kubectl get pod -n jenkins-k8s  -owide

3、验证

kubectl get pod -n jenkins-k8s -owide

curl 10.100.27.19:8080

4、kubectl apply -f jenkins-service.yaml

apiVersion: v1
kind: Service
metadata:name: jenkins-servicenamespace: jenkins-k8slabels:app: jenkins
spec:selector:app: jenkinstype: NodePortports:- name: webport: 8080targetPort: webnodePort: 30002- name: agentport: 50000targetPort: agent

kubectl get svc -n jenkins-k8s

cd /opt/nfsdata/jenkins/jenkins-home/secrets
