jenkins 部署
准备
- 创建namespace
kubectl create ns devops
- 准备pvc，用于jenkins插件等持久化的存储
# 查看是否有storageclass
kubectl get sc
# 如果已经有sc，
# 修改pvc.yaml中的storageClassName
# 默认写的是nas-storage
kubectl apply -f pvc.yaml -n devops
部署
- 修改clusterRoleBing 中的namespace
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
name: jenkins
roleRef:
apiGroup: rbac.authorization.k8s.io
kind: ClusterRole
name: jenkins
subjects:
- kind: ServiceAccount
name: jenkins
namespace: devops
- 如果需要ingress，修改对应的域名
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: jenkins-ingress
spec:
ingressClassName: nginx
rules:
- host: jenkins.sxkj.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: jenkins
port:
number: 30080
- 部署jenkins应用
kubectl apply -f deploy.yaml -n devops
- 验证，访问ip:30080，ip为pod调度到k8s某一个节点的ip，或者直接访问对应的域名: 如，jenkins.sxkj.com
配置jenkins
管理插件中下载插件
- git
- Pipeline
- git parameter
- publish over ssh
- Localization: Chinese (Simplified)
- kubernetes
- Blue Ocean
- Role-based Authorization Strategy
节点管理 -> Configure Cloud
- 添加凭据
