Deploy ob-operator

This article introduces the deployment methods for ob-operator.

1. Deployment Dependencies​

ob-operator relies on cert-manager. You can refer to the corresponding installation documentation for the installation of cert-manager.

2.1 Deploying with Helm​

ob-operator supports deployment using Helm. Before deploying ob-operator with the Helm command, you need to install Helm. After Helm is installed, you can deploy ob-operator directly using the following command.

helm repo add ob-operator https://oceanbase.github.io/ob-operator/
helm install ob-operator ob-operator/ob-operator --namespace=oceanbase-system --create-namespace

Parameters:

  • namespace: Namespace, can be customized. It is recommended to use "oceanbase-system" as the namespace.

2.2 Deploying with Configuration Files​

  • Stable
kubectl apply -f https://raw.githubusercontent.com/oceanbase/ob-operator/stable/deploy/operator.yaml
  • Development
kubectl apply -f https://raw.githubusercontent.com/oceanbase/ob-operator/master/deploy/operator.yaml

It is generally recommended to use the configuration files for the stable version. However, if you want to use a development version, you can choose to use the configuration files for the development version.

3. Check the deployment results​

After a successful deployment, you can view the definition of Custom Resource Definitions (CRDs) by executing the following command:

kubectl get crds

If you get the following output, it indicates a successful deployment:
