Deploy StarRocks with Docker

This QuickStart tutorial guides you through the procedures to deploy StarRocks on your local machine with Docker. Before getting started, you can read StarRocks Architecture for more conceptual details.

By following these steps, you can deploy a simple StarRocks cluster with one FE node and one BE node. It can help you complete the upcoming QuickStart tutorials on creating a table and loading and querying data, and thereby acquaints you with the basic operations of StarRocks.

CAUTION

Deploying StarRocks with the Docker image used in this tutorial merely applies to the situation when you need to verify a DEMO with a small dataset. It is not recommended for a massive testing or production environment. To deploy a high-availability StarRocks cluster, see Deployment overview for other options that suit your scenarios.

Prerequisites​

Before deploying StarRocks in Docker, make sure the following requirements are satisfied:

  • Hardware

    We recommend deploying StarRocks on a machine with 8 CPU cores and 16 GB of memory or more.

  • Software

    You must have the following software installed on your machine:

Step 1: Download the StarRocks Docker image​

Download a StarRocks Docker image from StarRocks Docker Hub. You can choose a specific version based on the tag of the image.

sudo docker run -p 9030:9030 -p 8030:8030 -p 8040:8040 \
    -itd registry.starrocks.io/starrocks/allin1-ubuntu

TROUBLESHOOTING

If any of the above ports on the host machine is occupied, the system prints "docker: Error response from daemon: driver failed programming external connectivity on endpoint tender_torvalds (): Bind for 0.0.0.0:xxxx failed: port is already allocated.". You can allocate available ports on the host machine by changing the ports preceding the colons (:) in the command.

You can check if the container is created and running properly by running the following command:

sudo docker ps

As shown below, if the STATUS of your StarRocks containers is Up, you have successfully deployed StarRocks in the Docker container.

CONTAINER ID   IMAGE                                          COMMAND                  CREATED         STATUS                 PORTS                                                                                                                             NAMES
8962368f9208   starrocks/allin1-ubuntu:branch-3.0-0afb97bbf   "/bin/sh -c ./start_…"   4 minutes ago   Up 4 minutes           0.0.0.0:8037->8030/tcp, :::8037->8030/tcp, 0.0.0.0:8047->8040/tcp, :::8047->8040/tcp, 0.0.0.0:9037->9030/tcp, :::9037->9030/tcp   xxxxx

Step 2: Connect to StarRocks​

After StarRocks is deployed properly, you can connect to it via a MySQL client.

mysql -P9030 -h127.0.0.1 -uroot --prompt="StarRocks > "

CAUTION

If you have allocated a different port for 9030 in the docker run command, you must replace 9030 in the above command with the port you have allocated.

You can check the status of the FE node by executing the following SQL:

SHOW PROC '/frontends'\G

Example:

StarRocks > SHOW PROC '/frontends'\G
*************************** 1. row ***************************
             Name: 8962368f9208_9010_1681370634632

      EditLogPort: 9010
         HttpPort: 8030
        QueryPort: 9030
          RpcPort: 9020
             Role: LEADER
        ClusterId: 555505802
             Join: true
            Alive: true

  • If the field Alive is true, this FE node is properly started and added to the cluster.
  • If the field Role is FOLLOWER, this FE node is eligible to be elected as the Leader FE node.
  • If the field Role is LEADER, this FE node is the Leader FE node.

You can check the status of the BE node by executing the following SQL:

SHOW PROC '/backends'\G

Example:

StarRocks > SHOW PROC '/backends'\G
*************************** 1. row ***************************
            BackendId: 10004
                   IP: 8962368f9208

If the field Alive is true, this BE node is properly started and added to the cluster.

Stop and remove the Docker container​

After completing the whole QuickStart tutorial, you can stop and remove the container that hosts your StarRocks cluster with its container ID.

NOTE

You can get the container_id of your Docker container by running sudo docker ps.

Run the following command to stop the container:

# Replace <container_id> with the container ID of your StarRocks cluster.
sudo docker stop <container_id>

If you do not need the container any longer, you can remove it by running the following command:

# Replace <container_id> with the container ID of your StarRocks cluster.
sudo docker rm <container_id>

CAUTION

The removal of the container is irreversible. Make sure you have a backup of the important data in the container before removing it.

What to do next​

Having deployed StarRocks, you can continue the QuickStart tutorials on creating a table and loading and querying data.
