rainbond-operator

Operation mode​

Running inside the Kubernetes cluster, POD running

brief introduction​

tip

rainbond-operator controls the configuration and running status of all components of Rainbond, continuously monitors the status of each component, and makes different actions. For example, if the pod instance of rbd-db is deleted or the parameters are modified, the operator will give feedback immediately.

rainbond-operator is based on kubebuilder implementation.

When installing the cluster side, the rainbond-operator will be installed first, and then some CRD resources will be created, as follows：

  • rainbondclusters.rainbond.io
  • rbdcomponents.rainbond.io

rainbondclusters.rainbond.io​

rainbondclusters.rainbond.io is the configuration file on the cluster side, such as setting gateway nodes, building nodes, etc.

After the cluster is installed, we can modify gateway nodes, build nodes, database connection information, etc. through this CRD resource.

kubectl edit rainbondclusters.rainbond.io -n rbd-system

rbdcomponents.rainbond.io​

rbdcomponents.rainbond.io is the CRD resource of all PODs on the console cluster side. All controllers and PODs will be created. You can also modify the configuration of the corresponding components after the installation is complete.

# Query components
kubectl get rbdcomponents.rainbond.io -n rbd-system

# Edit rbdcomponents all components configuration
kubectl edit rbdcomponents.rainbond.io -n rbd-system

# Edit rbdcomponents rbd-api configuration
kubectl edit rbdcomponents.rainbond .io rbd-api -n rbd-system
