Quick Start

To deploy a storage-computing separation cluster on K8s, FDB deployed in advance is required. If it is a virtual machine deployment, please ensure the deployed virtual machine can be accessed by the services on the K8s cluster. For deployment, please refer to Before Deployment doc; if deploy on K8s, please refer to FDB deployment on k8s.
Doris storage-computing separation cluster deployment is divided into two parts: deploying Doris-Operator and its RBAC resources; Deploying customized resource DorisDisaggregatedCluster.

Step 1: Deploy Operator

1. Issue resource definitions:

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

Expected Results:

customresourcedefinition.apiextensions.k8s.io/dorisdisaggregatedclusters.disaggregated.cluster.doris.com created
customresourcedefinition.apiextensions.k8s.io/doris.selectdb.com_dorisclusters.yaml created

2. Deploy Doris-Operator and dependent RBAC rules:

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

Expected Results:

kubectl -n doris get pods
NAME                              READY   STATUS    RESTARTS   AGE
doris-operator-6b97df65c4-xwvw8   1/1     Running   0          19s

Step 2: Quickly deploy a storage and computing separation cluster

1. Download the ddc-sample.yaml deployment sample:

curl -O https://raw.githubusercontent.com/apache/doris-operator/master/doc/examples/disaggregated/cluster/ddc-sample.yaml

2. According to the documents of deploying doris storage and computing separation cluster, configure metaService in the metadata configuration; configure the fe specifications in the fe configuration; and configure the resource groups in the compute cluster configuration. After the configuration is completed, use the following command to deploy resource:

kubectl apply -f ddc-sample.yaml

After the deployment resource is delivered, using the command kubectl get ddc to check the cluster status. The expected successful result is as follow:

kubectl get ddc
NAME                         CLUSTERHEALTH   FEPHASE   CGCOUNT   CGAVAILABLECOUNT   CGFULLAVAILABLECOUNT
test-disaggregated-cluster   green           Ready     2         2                  2

Tip

MS service needs to use FDB as the backend metadata storage. FDB service must be deployed before deploying MS service. Please deploy it in advance according to install FDB.

Step 3: Creating remote storage vault

After the cluster is built, you need to execute the corresponding CREATE STORAGE VAULT SQL statement through the client to create a storage backend to achieve data persistence. Refer to Accessing Doris Cluster to connect to the Doris cluster. One of the implementation methods is provided below.

1. Get service

After deploying the cluster, you can view the service exposed by Doris Operator by using the following command:

kubectl -n doris get svc

The returned results are as follows:

NAME                                     TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                               AGE
test-disaggregated-cluster-fe            ClusterIP   10.96.147.97   <none>        8030/TCP,9020/TCP,9030/TCP,9010/TCP   15m
test-disaggregated-cluster-fe-internal   ClusterIP   None           <none>        9030/TCP                              15m
test-disaggregated-cluster-ms            ClusterIP   10.96.169.8    <none>        5000/TCP                              15m
test-disaggregated-cluster-cg1           ClusterIP   10.96.47.90    <none>        9060/TCP,8040/TCP,9050/TCP,8060/TCP   14m
test-disaggregated-cluster-cg2           ClusterIP   10.96.50.199   <none>        9060/TCP,8040/TCP,9050/TCP,8060/TCP   14m

2. Access by MySQL Client

Use the following command to create a pod containing the mysql client in the current Kubernetes cluster:

kubectl run mysql-client --image=mysql:5.7 -it --rm --restart=Never --namespace=doris -- /bin/bash

In the container within the cluster, you can use the fe service name to access the Doris cluster:

mysql -uroot -P9030 -h test-disaggregated-cluster-fe  

3. Create storage vault

Create statement syntax, please refer to managing storage vault.
Here is an example of S3 protocol object storage:

1. Create S3 Storage Vault

CREATE STORAGE VAULT IF NOT EXISTS s3_vault
    PROPERTIES (
        "type"="S3",                                   -- required
        "s3.endpoint" = "oss-cn-beijing.aliyuncs.com", -- required
        "s3.region" = "bj",                            -- required
        "s3.bucket" = "bucket",                        -- required
        "s3.root.path" = "big/data/prefix",            -- required
        "s3.access_key" = "ak",                        -- required
        "s3.secret_key" = "sk",                        -- required
        "provider" = "OSS"                             -- required
    );

2. Set the default storage vault

SET s3_vault AS DEFAULT STORAGE VAULT;
