Deploy SeekDB with Docker

Introduction

The seekdb Docker image, available on dockerhub, quay.io and ghcr.io, is designed for users to quickly set up a SeekDB environment for testing purposes.

Key ***ations:

• There are known issues running this image on MacOS and intel chip with docker version greater than 4.9.0, you can download the desired version of docker from this link.
• This image is intended for testing only; do not use it in production environments.

Prerequisites

Before deploying seekdb, ensure that the following requirements are met:

• The host machine should have at least 1 physical cores and 2GB of memory.
• Docker should be installed and running on the host machine. Refer to the Docker installation guide.

Starting a SeekDB Instance

To start a SeekDB instance, use the following commands:

bash
docker run -d -p 2881:2881 -p 2886:2886 oceanbase/seekdb

# Execute init SQL scripts after bootstrap, you need to mount the directory containing the init scripts then specify the directory in container via environment variable INIT_SCRIPTS_PATH.
# Please do not change root user's password in SQL scripts. If you'd like to change root user's password, use environment variable ROOT_PASSWORD.
docker run -d -p 2881:2881 -p 2886:2886 -v {init_sql_folder_path}:/root/boot/init.d -e INIT_SCRIPTS_PATH=/root/boot/init.d oceanbase/seekdb

Supported Environment Variables

Below is a table of supported environment variables for the image:

If you'd like to modify other SeekDB parameters, you can do mount a configuration file into /etc/oceanbase/seekdb.cnf in the container, the default configuration file is as follows.

datafile_size=2G
datafile_next=2G
datafile_maxsize=50G
cpu_count=4
memory_limit=2G
log_disk_size=2G
# config the parameter in the following format
# key=value

The start command should be like this.

# **Note:** If you decide to use a configuration file, please don't specify the resource related environment variables.
docker run -d -p 2881:2881 -p 2886:2886 -v {config_file}:/etc/oceanbase/seekdb.cnf oceanbase/seekdb

Data Persistence

Seekdb deploys in directory /var/lib/oceanbase, if you'd like to persist the data on the host server, please mount an empty directory on the host server to this path.

Note: If you run seekdb container on windows, please use docker volume instead of directory on the host to ensure it works properly.

# On Linux or MacOS
mkdir -p seekdb
docker run -d -p 2881:2881 -p 2886:2886 -v $PWD/seekdb:/var/lib/oceanbase --name seekdb oceanbase/seekdb

# On Windows
docker volume create seekdb
docker run -d -p 2881:2881 -p 2886:2886 -v seekdb:/var/lib/oceanbase --name seekdb oceanbase/seekdb

Connecting to SeekDB Instance

mysql -h 127.0.0.1 -P 2881 -u root -p    # Connect with the root account

Access dashboard

The container provides a user-friendly web interface, you can access it in the browser [***]{server_ip}:2886, the login password is the same as user root's password. If ROOT_PASSWORD is not set, leave the password field blank.
