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. Installing Doris Operator CRD 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.selectdb.com_dorisclusters.yaml
    Expected output:
    customresourcedefinition.apiextensions.k8s.io/dorisclusters.doris.selectdb.com created
  2. Install Doris Operator 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 Doris Operator status 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 cluster deployment status: 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
