k8s集群安装jenkins

官网地址（温馨提示，先复制到文本文件中再复制到具体机器上）

linux安装 https://blog.youkuaiyun.com/weixin_47533244/article/details/127804283

https://www.jenkins.io/doc/book/installing/kubernetes/#create-a-namespace

1.创建命名空间

kubectl create namespace jenkins

2.创建jenkins账号serviceAccount

mkdir -p /usr/local/data/jenkins/
cd /usr/local/data/jenkins/
vim jenkins-service-account.yaml

---

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: jenkins
rules:

• apiGroups: [“”]
  resources: [““]
  verbs: [””]

---

apiVersion: v1
kind: ServiceAccount
metadata:
name: jenkins
namespace: jenkins

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: jenkins

---

保存文件并创建
kubectl apply -f jenkins-service-account.yaml

创建持久卷-以local类型的卷举例

vim jenkins-volumn.yaml

kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer

apiVersion: v1
kind: PersistentVolume
metadata:
name: jenkins-pv-volume
labels:
type: local
spec:
storageClassName: local-storage
claimRef:
name: jenkins-pv-claim
namespace: jenkins
capacity:
storage: 10Gi
accessModes:
- ReadWriteOnce
local:
path: /mnt
nodeAffinity:
required:
nodeSelectorTerms:
- matchExpressions:
- key: kubernetes.io/hostname
operator: In
values:
- worker-node01 # 改成自己的节点名称

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: jenkins-pv-claim
namespace: jenkins
spec:
storageClassName: local-storage
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 3Gi

保存并创建
kubectl create -f jenkins-volume.yaml

创建deployment

vim jenkins-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: jenkins
namespace: jenkins
spec:
replicas: 1
selector:
matchLabels:
app: jenkins-server
template:
metadata:
labels:
app: jenkins-server
spec:
securityContext:
fsGroup: 1000
runAsUser: 1000
serviceAccountName: jenkins
containers:
- name: jenkins
image: jenkins/jenkins:lts
resources:
limits:
memory: “2Gi”
cpu: “1000m”
requests:
memory: “500Mi”
cpu: “500m”
ports:
- name: httpport
containerPort: 8080
- name: jnlpport
containerPort: 50000
livenessProbe:
httpGet:
path: “/login”
port: 8080
initialDelaySeconds: 90
periodSeconds: 10
timeoutSeconds: 5
failureThreshold: 5
readinessProbe:
httpGet:
path: “/login”
port: 8080
initialDelaySeconds: 60
periodSeconds: 10
timeoutSeconds: 5
failureThreshold: 3
volumeMounts:
- name: jenkins-data
mountPath: /var/jenkins_home
volumes:
- name: jenkins-data
persistentVolumeClaim:
claimName: jenkins-pv-claim

保存并创建
kubectl apply -f jenkins-deployment.yaml
至此jenkins安装完成.接下来创建service或者Ingress暴露外部访问方法
