k8s搭建web界面管理rancher

rancher部署

一、准備介質

鏡像v2.4.17

docker pull rancher/rancher:v2.4.17

二、使用docker安裝

點擊查看代碼

 docker run -d --restart=unless-stopped -p 80:80 -p 443:443 \
 -v /home/ap/aipf/rancher_home/rancher:/var/lib/rancher \
 -v /home/ap/aipf/rancher_home/auditlog:/var/log/auditlog \
 --name rancher rancher/rancher:v2.4.17

訪問本機ip

三、使用k8s部署rancher

3.1、創建namespace

kubectl create ns rancher

3.2、創建rancher的存儲路徑pv/pvc

點擊查看代碼

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-rancher
  namespace: rancher
spec:
  capacity:
    storage: 20Gi
  accessModes:
  - ReadWriteMany
  persistentVolumeReclaimPolicy: Retain
  storageClassName: local-storage
  local:
    path: /home/ap/nas_b
  nodeAffinity:
    required:
      nodeSelectorTerms:
      - matchExpressions:
        - key: kubernetes.io/hostname
          operator: In
          values:
          - k8s-master
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-rancher
  namespace: rancher
spec:
  accessModes:
   - ReadWriteMany
  storageClassName: local-storage
  resources:
    requests:
      storage: 15Gi

3.3、創建rancher的配置文件

點擊查看代碼

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: rancher
  name: rancher
  namespace: rancher
spec:
  replicas: 1
  selector:
    matchLabels:
      app: rancher
  template:
    metadata:
      labels:
        app: rancher
      containers:
      - image: rancher/rancher:v2.4.17
        imagePullPolicy: IfNotPresent
        name: rancher
        envFrom:
        - configMapRef:
            name: ai-platform-config
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /var/lib/rancher
          name: ai-rancher-volumes
          subPath: rancher_home/rancher
        - mountPath: /var/log/auditlog
          name: ai-rancher-volumes
          subPath: rancher_home/auditlog

      volumes:
      - name: ai-rancher-volumes
        persistentVolumeClaim:
          claimName: pvc-rancher
---
apiVersion: v1
kind: Service
metadata:
  name: rancher
  labels:
    app: rancher
  namespace: rancher
spec:
  type: ClusterIP
  selector:
    app: ai-admin-web
  ports:
  - port: 80
    targetPort: 80

注意:k8s集群多的時候，配置文件可以添加標簽指定rancherd pod啟動到固定節點上 也可以搭建harbor 拉取鏡像從harbor獲取 第一次啟動rancher可以掛載目錄為空，需要你這邊使用docker啟動后，在吧數據拷貝進去，然后在重啟

apiVersion: apps/v1
kind: Deployment

    app: rancher
  name: rancher
  namespace: rancher

  replicas: 1

      - image: rancher.harbor.io/rancher/rancher:v2.4.17
        imagePullPolicy: IfNotPresent
        name: rancher
        envFrom:
        - configMapRef:
            name: ai-platform-config
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /var/lib/rancher
          name: ai-rancher-volumes
          subPath: rancher_home/rancher
        - mountPath: /var/log/auditlog
          name: ai-rancher-volumes
          subPath: rancher_home/auditlog

      volumes:
      - name: ai-rancher-volumes
        persistentVolumeClaim:
          claimName: pvc-rancher
---
apiVersion: v1
kind: Service
metadata:
  name: rancher
  labels:
    app: rancher
  namespace: rancher
spec:
  type: ClusterIP
  selector:
    app: ai-admin-web
  ports:
  - port: 80
    targetPort: 80


3.4、使用上面的配置文件啟動rancher服務

[root@k8s-master conf]# kubectl apply -f rancher-pv.yaml 
persistentvolume/pv-rancher created
persistentvolumeclaim/pvc-rancher created

[root@k8s-master conf]# kubectl get pv,pvc -A | grep rancher
persistentvolume/pv-rancher   20Gi       RWX            Retain           Bound    rancher/pvc-rancher     local-storage            79s
rancher       persistentvolumeclaim/pvc-rancher   Bound    pv-rancher   20Gi       RWX            local-storage   79s

3.5、啟動rancher服務

[root@k8s-master conf]# kubectl apply -f rancher.yaml 
deployment.apps/rancher created
service/rancher created
