基于 jenkins+gitlab+springcloud+harbor+nexus 构建 Devops

1、安装和配置 jenkins

K8s 集群：

[root@xianchaomaster1 ~]# kubectl get nodes

NAME STATUS ROLES AGE VERSION

xianchaomaster1 Ready control-plane,master 69d v1.23.1

xianchaonode1 Ready <none> 69d v1.23.1

1.1、安装 Jenkins

在 k8s 集群安装 jenkins

[root@xianchaomaster1 ~]# systemctl start nfs

[root@xianchaomaster1 ~]# systemctl enable nfs

[root@xianchaonode1 ~]# yum install nfs-utils -y

[root@xianchaonode1 ~]# systemctl start nfs

[root@xianchaonode1 ~]# systemctl enable nfs

（2）在 xianchaomaster1 上创建一个 nfs 共享目录

[root@xianchaomaster1 ~]# mkdir /data/v2 -p

[root@xianchaomaster1 ~]# vim /etc/exports

/data/v1 *(rw,no_root_squash)

/data/v2 *(rw,no_root_squash)

[root@xianchaomaster1 ~]# kubectl create namespace jenkins-k8s

（2）创建 pv

#更新资源清单文件

[root@xianchaomaster1]# kubectl apply -f pv.yaml

#查看 pv 是否创建成功

[root@xianchaomaster1]# kubectl get pv

pv.yaml 文件内容如下：

apiVersion: v1

kind: PersistentVolume

metadata:

nfs:

server: 192.168.40.180

path: /data/v2

[root@xianchaomaster1]# kubectl apply -f pvc.yaml

pvc.yaml 文件内容如下：

kind: PersistentVolumeClaim

apiVersion: v1

metadata:

name: jenkins-k8s-pvc

namespace: jenkins-k8s

spec:

resources:

requests:

storage: 10Gi

[root@xianchaomaster1]# kubectl create clusterrolebinding jenkins-k8s-sa-cluster -n

jenkins-k8s --clusterrole=cluster-admin --serviceaccount=jenkins-k8s:jenkins-k8s-sa

（6）通过 deployment 部署 jenkins

[root@xianchaonode1 ~]# docker load -i jenkins-2.328.tar.gz

[root@xianchaonode1 ~]#

docker load -i jenkins-jnlp.tar.gz

#更新资源清单文件

[root@xianchaomaster1]# kubectl apply -f jenkins-deployment.yaml

#查看 jenkins 是否创建成功

[root@xianchaomaster1 jenkins]# kubectl get pods -n jenkins-k8s

NAME READY STATUS RESTARTS AGE

jenkins-74b4c59549-g5j9t 0/1 CrashLoopBackOff 3 67s

#报错显示没有权限操作/var/jenkins_home/copy_reference_file.log 文件，解决办法如下：

[root@xianchaomaster1]# kubectl delete -f jenkins-deployment.yaml

[root@xianchaomaster1]# chown -R 1000.1000 /data/v2

[root@xianchaomaster1]# kubectl apply -f jenkins-deployment.yaml

[root@xianchaomaster1]# kubectl get pods -n jenkins-k8s

jenkins-74b4c59549-6xpnk 1/1 Running 0 66

kind: Deployment

apiVersion: apps/v1

metadata:

name: jenkins

namespace: jenkins-k8s

spec:

replicas: 1

selector:

matchLabels:

app: jenkins

containers:

- name: jenkins

image:

imagePullPolicy: IfNotPresent

ports:

- containerPort: 8080

- containerPort: 50000

livenessProbe:

volumeMounts:

- name: jenkins-volume

volumes:

- name: jenkins-volume

[root@xianchaomaster1]# kubectl apply -f jenkins-service.yaml

#查看 service 是否创建成功

[root@xianchaomaster1]# kubectl get svc -n jenkins-k8s

#通过上面可以看到 service 的 8080 端口在物理机映射的端口是 30002

jenkins-service.yaml 文件内容如下：

apiVersion: v1

kind: Service

metadata:

name: jenkins-service

type: NodePort

ports:

- name: web

port: 8080

- name: agent

在浏览器访问 jenkins 的 web 界面：

http://192.168.40.180:30002/login?from=%2F

在 nfs 服务端，也就是我们的 master1 节点获取密码：

[root@xianchaomaster1 ~]# cat /data/v2/jenkins-home/secrets/initialAdminPassword

把上面获取到的密码拷贝到上面管理员密码下的方框里
