Using helm to install rainbow in various kubernetes

utilize Helm install Rainbond

Haoyu technology team has been committed to making it easier for users to install Rainbond This product .

not long ago , We've just introduced deploying in one container Rainbond Of Fast installation The way , This way covers Windows、MacOS、Linux Three operating systems , Can also be applied to x86_64 、Arm64 Two mainstream architectures . This installation method greatly simplifies the user's operation process , Improved user experience . However, this installation method is limited to a single machine , For experience only Rainbond Function or personal development environment , Not suitable for deployment in a production environment .

Haoyu technology and technology team has launched a platform based on Helm Installation method of . Helm Provides a simple set of commands , With the help of developers Charts The package completes the installation of the application 、 to update 、 upgrade 、 Rollback and other operations .Kubernetes Has become a modern enterprise IT De facto standards for infrastructure , and Helm As a package management tool, it adapts to most of the Kubernetes type , These types include ：

• Use different installation tools （ Such as kubeadm、sealos） Various versions of standards deployed Kubernetes colony
• Launched by major cloud service providers Kubernetes As a service cloud product , Such as ali cloud ACK、 Tencent cloud TKE
• be based on Kubernetes Other container infrastructure implemented by the specification , Such as K3s 、Kubedge

With the help of Helm Wide applicability of , We are looking forward to Rainbond Get in a variety of complex Kubernetes Ability to take root in the scene .

advantage

utilize Helm install Rainbond Installation method of , Remove targeting different types Kubernetes Beyond the wide applicability of , There are other advantages .

• Highly customized

We will be around Rainbond Custom configuration that can be set , To pass through values.yaml Exposed in the form of configuration files . The user can according to values.yaml Detailed explanation Document guidelines , Adjust yourself Rainbond Install predefined configurations . When the user's Kubernetes It is very useful when the cluster has a custom infrastructure and needs to be docked , For example, docking different storage 、 Load balancing 、 Database etc. . Previous installation methods can also support this configuration , however Helm Customization of installation method is the most convenient and reasonable .

• Easy to adjust cluster configuration

Inherited from highly customized properties , Users can refer to values.yaml Detailed explanation Document guidelines , After simple file editing , Complete with one command Rainbond Adjustment of cluster configuration .

• Clear and unmistakable command line operation mode

Compared with the previous graphical installation methods ,Helm The installation is based on the command line and configuration file , Minimize the possibility of ambiguity . Each command line operation has a clear return information , It is very much in line with the appetite of system operation and maintenance personnel .

Applicable people

Helm The only disadvantage of the installation method is that it requires high technical threshold for operators , Enterprises Kubernetes Cluster operation and maintenance management personnel are more suitable candidates . Operation and maintenance management personnel have the following characteristics .

• Yes Kubernetes Have in-depth understanding of the system

Use Helm Install application , Need to be right Kubernetes Have a certain understanding of the system . Once problems occur during installation , The operator is required to have debugging skills Kubernetes The ability of resources .

• Able to accept command line interaction

Operators and Helm The interaction between them is completely based on the form of command line , There is no graphical interface support .

• Yes Rainbond Clusters have high customization requirements

Owned by operators Kubernetes The more complex the cluster is , On the other hand Rainbond The higher the degree of customization required . Especially when hosting with different cloud service providers Kubernetes The service , It is very important to connect the other infrastructures around the cluster perfectly . These custom configurations will have a profound impact on Rainbond High availability and use experience of cluster .

Operation process

utilize Helm Based on the existing Kubernetes Cluster installation Rainbond, The process is relatively simple , All operations are based on the command line .

Environmental requirements

Helm edition ：3+

Kubernetes edition ： 1.19+

Helm install

• establish rbd-system Namespace

kubectl create namespace rbd-system

• add to chart Warehouse

helm repo add rainbond https://openchart.goodrain.com/goodrain/rainbond

• install ranibond

helm install rainbond rainbond/rainbond-cluster -n rbd-system

values.yaml

Users can create a configuration file values.yaml From definition Rainbond Configuration of cluster . The most common configuration items , Including the selection of gateway nodes , As well as the cluster's external network export IP Configuration of .

• Selection of gateway nodes

Kubernetes At least one node in the cluster needs to be provided as a node Rainbond Gateway nodes ,Rainbond Gateway service rbd-gateway It's a kind of Ingress-controller Realization , And other Ingress-controller Working together can lead to port conflicts , requirement 80、443、6060、7070、8443 Free .

• Cluster external network export IP

This configuration is closely related to the gateway node , stay Kubernetes Services running in the cluster , The service address needs to be exposed through the gateway node , Whether it's based on Http still Tcp, Will eventually be mapped to a IP Address . this IP It is possible that the server of the gateway node is mapped to the public network IP Address , It may also be the result of load balancing outside the gateway node IP Address , Through port mapping 80、443. If you don't set it , The intranet of the gateway node is selected by default IP Address .

Configuration mode , It is simple file editing ：

cat > values.yaml << EOFCluster:#  External gateway , Fill in IP  gatewayIngressIPs: 47.104.1.82  #  Corresponding configuration of gateway node ,externalIP For the gateway node IP,internalIP For the gateway node IP,name For the gateway node node name   nodesForGateway:  - externalIP: 47.104.1.82    internalIP: 192.168.0.1    name: node1EOF

After generating the configuration file , In the installation Rainbond Reference the configuration file when ：

helm install rainbond rainbond/rainbond-cluster -f values.yaml -n rbd-system

Reference resources helm Installation and uninstallation guide To uninstall based on Helm Installed Rainbond colony . There was a problem during the installation , Reference resources helm Installation troubleshooting guide Do troubleshooting .
