Deploy on Kubernetes

This section describes how to deploy Doris Operator and Doris cluster in the test Kubernetes cluster. The deployment operations are as follows:

1. Deploy Doris Operator
2. Deploy Doris cluster
3. Connect to Doris cluster

Step 1: Deploy Doris Operator

Deploying Doris Operator consists of two parts: installing the definition and deploying the operator service:

1. Add the custom resource (CRD) of Doris Operator using the following command:

   kubectl create -f https://raw.githubusercontent.com/apache/doris-operator/master/config/crd/bases/doris.apache.com_dorisclusters.yaml

2. Install Doris Operator using the following command:

   kubectl apply -f https://raw.githubusercontent.com/apache/doris-operator/master/config/operator/operator.yaml

   Expected output:

   namespace/doris created
   role.rbac.authorization.k8s.io/leader-election-role created
   rolebinding.rbac.authorization.k8s.io/leader-election-rolebinding created
   clusterrole.rbac.authorization.k8s.io/doris-operator created
   clusterrolebinding.rbac.authorization.k8s.io/doris-operator-rolebinding created
   serviceaccount/doris-operator created
   deployment.apps/doris-operator created

3. Check the deployment status of Doris Operator using the following command:

   kubectl get pods -n doris

   Expected output:

   NAME                              READY   STATUS    RESTARTS   AGE
   doris-operator-7f578c86cb-nz6jn   1/1     Running   0          19m

Step 2: Deploy Doris cluster

1. Download the template Doris deployment template:

   curl -O https://raw.githubusercontent.com/apache/doris-operator/master/doc/examples/doriscluster-sample.yaml
2. Perform customized configuration as needed according to the doc of Config Doris to Deploy. After the configuration is completed, deploy it with the following command:

   kubectl apply -f doriscluster-sample.yaml
3. Check the status of the cluster by checking the status of pods:

   kubectl get pods
   Expected output:

   NAME                       READY   STATUS    RESTARTS   AGE
   doriscluster-sample-fe-0   1/1     Running   0          2m
   doriscluster-sample-be-0   1/1     Running   0          3m
   Check the status of the deployed resources:

   kubectl get dcr -n doris
   Expected output:

   NAME                  FESTATUS    BESTATUS    CNSTATUS   BROKERSTATUS
   doriscluster-sample   available   available

Step 3: Access the Doris cluster

The Doris cluster is quickly deployed in the test environment. You can enter the container FE and use the MySQL Client to connect to Doris for test operations. For other access methods, refer to Accessing Doris Cluster for configuration.

1. Get the FE container name:

   kubectl get pod -n doris | grep fe
   doriscluster-sample-fe-0          1/1     Running   0          16m

   In this example, the FE container is named doriscluster-sample-fe-0.

2. Enter the FE container:

   kubectl -n doris exec -it doriscluster-sample-fe-0 /bin/bash

3. Use MySQL Client to connect to the Doris cluster in the FE container:

   mysql -uroot -P9030 -h127.0.0.1
