mkdir ~/.kube/
vi ~/.kube/config

install helm​

wget https://pkg.goodrain.com/pkg/helm && chmod +x helm && mv helm /usr/local/bin/

Create the values.yaml file​

  • In a custom form, choose the configuration of the rainbond cluster and whether to connect to the existing Alibaba Cloud RDS, NAS, mirror warehouse, etc.
$ vi values.yaml

##Rainbondcluster
Cluster:
## Define whether to enable high availability, true is on, false is off, the default replica set under high availability is 2
  enableHA: false

## Define whether to use external mirror images Warehouse, true is on, false is off, the user needs to provide the domain name, space name, user name and password of the existing mirror warehouse
  imageHub:
    enable: false
    domain: fdfef-hangzhou.aliyuncs.com
    namespace: sefe
    password: grddgar
    username: zfefee

## External ETCD, corresponding to fill in IP, certificate, true is on, false is off, if you have Alibaba Cloud ETCD, you can directly fill in the IP
  etcd:
    enable: false
    endpoints: 
    - 192.168 .0.1:2379 
    - 192.168.0.2:2379
    - 192.168.0.3:2379
    secretName: "rbd-etcd-secret"

## External storage, true is on, false is off, if you need to connect to Alibaba Cloud NAS storage, If you need to modify the mount parameters, you can modify the parameters below mountOptions according to the format, and directly modify the server address for the mount point.
  RWX:
    enable: false
    config:
      csiPlugin:
        aliyunNas:
          accessKeyID: ""
          accessKeySecret: ""
      storageClassParameters:
## mountOptions:
## - "nolock,tcp,noresvport"
## - "vers=4"
        parameters:
          volumeAs: subpath
          archiveOnDelete: "true"
          server: NAS_SERVER_ADDR

## External storage, Fill in storageClassName directly, true is on, false is off
  RWO:
    enable: false
    storageClassName: glusterfs-simple

## region database, true If it is on, false is off. Alibaba Cloud users must provide an external high-availability RDS Mysql 8.0 database. The region database needs to be created in advance in this database, and the RDS domain name, user name, and password that can be accessed by the intranet must be provided.
  regionDatabase:
    enable: false
    host: 4444f-8vbidfd.mysql.zhangbei.rds.aliyuncs.com 
    name: region
    password: gr12dfe
    port: 3306
    username: admin

## ui database, true is on, false is off, Aliyun user Be sure to provide an external high-availability RDS Mysql 8.0 database, in which the console database needs to be created in advance, and the RDS domain name, user name, and password accessible to the intranet need to be provided.
  uiDatabase:
    enable: false
    host: 4444f-8vbidfd.mysql. zhangbei.rds.aliyuncs.com
    name: console
    password: gr12dfe
    port: 3306
    username: admin

## External gateway, fill in SLB public IP
  gatewayIngressIPs: 121.89.194.127

## chaos corresponding configuration, high availability environment , select at least 2 nodes as cluster construction service running nodes, name is the node name of the back-end server node
  nodesForChaos:
  - name: cn-zhangjiakou.10.22.197.170
  - name: cn-zhangjiakou.10.22.197.171

# # Configure corresponding gateway nodes. In a high availability environment, at least two nodes are selected as cluster gateway nodes. It is recommended to use all nodes as gateway nodes. It is required that ports 80, 443, 6060, 7070, and 8443 of the nodes are not occupied.name Fill in the name of the node node.
  nodesForGateway:
  - externalIP: 10.22.197.170
    internalIP: 10.22.197.170
    name: cn-zhangjiakou.10.22.197.170

Install Rainbond with Helm​

  • Create the rbd-system namespace
kubectl create namespace rbd-system
  • Add chart repository
helm repo add rainbond https://openchart.goodrain.com/goodrain/rainbond
  • install rainbond
helm install rainbond rainbond/rainbond-cluster -f values.yaml -n rbd-system

Verify installation​

  • View pod status
kubectl get po -n rbd-system | grep rbd-app-ui
  • Wait for the rbd-app-ui pod to be in the Running state and the installation is successful.
  • After successful installation, the rainbond console can be accessed $gatewayIngressIPs:.
