Quick Reference
- Maintainers: https://github.com/enmotech
- Where to get help: Mo Tian Lun-openGauss
If you are attempting to run a container of openGauss version 5.0 or later on macOS or Windows, you should use the https://hub.docker.com/r/enmotech/opengauss-lite version. This is because since version 5.0, the openGauss EE container cannot start up properly on macOS or Windows. However, there are no issues when running it on Linux.

Features of Enmotech openGauss Image
- Enmotech closely tracks changes in the openGauss source code and releases new versions of the image promptly.
- Enmotech's cloud database, virtual machine database, and container version database all use the same best practice initialization configuration, ensuring a nearly identical experience when dealing with various requirements.
- Enmotech continuously releases various images for different CPU architectures (x86 or ARM) and operating systems.
Currently supports x86-64 and ARM64 architectures, automatically determined based on the machine architecture when obtaining the image.
From version 5.0 (including 5.0):
- Enterprise edition and Lite edition separated. https://hub.docker.com/r/enmotech/opengauss/tags is Enterprise edition, https://hub.docker.com/r/enmotech/opengauss-lite/tags is Lite edition.
From version 3.0 (including 3.0):
- The container uses the openGauss Database Lite version
- Default startup with idle memory less than 200M
- Added basic commands such as vi, ps, etc.
From version 2.0 (including 2.0):
- openGauss for x86-64 architecture runs on the Ubuntu 18.04 operating system
- openGauss for ARM64 architecture runs on the Debian 10 operating system
Before version 1.1.0 (including 1.1.0):
- openGauss for x86-64 architecture runs on the CentOS 7.6 operating system
- openGauss for ARM64 architecture runs on the openEuler 20.03 LTS operating system
How to Use This Image
Start an openGauss Instance
console$ docker run --name opengauss --privileged=true -d -e GS_PASSWORD=Enmo@123 enmotech/opengauss:latest
Environment Variables
To use the openGauss image more flexibly, additional parameters can be set. More controllable parameters will be added in future versions. The current version supports the following variables.
GS_PASSWORD
This parameter must be set when using the openGauss image. The value cannot be empty or undefined. This parameter sets the password for the openGauss database superuser omm and the test user gaussdb. The omm superuser is created by default during openGauss installation and the username cannot be changed at this time. The test user gaussdb is a custom-created user in the https://github.com/enmotech/enmotech-docker-opengauss/blob/master/1.0.1/entrypoint.sh.
The openGauss image is configured with local trust mechanism, so no password is required to connect to the database within the container. However, if connecting from outside the container (other hosts or other containers), a password must be entered.
openGauss password complexity requirements: the password must be at least 8 characters long and contain uppercase and lowercase English letters, numbers, and special characters.
GS_NODENAME
Specifies the database node name. The default is gaussdb.
GS_USERNAME
Specifies the database connection username. The default is gaussdb.
GS_PORT
Specifies the database port. The default is 5432.
Connecting to the Container Database from Outside the Container
openGauss listens on port 5432 within the container by default. To access the database from outside the container, specify the -p parameter when running docker run. For example, the following command allows access to the container database using port ***.
console$ docker run --name opengauss --privileged=true -d -e GS_PASSWORD=Secretpassword@123 -p 15432:5432 enmotech/opengauss:latest
After successfully starting the container database with the above command, you can access the database using gsql from outside.
console$ gsql -d postgres -U gaussdb -W'Secretpassword@123' -h your-host-ip -p15432
Persistent Storage Data
Once a container is deleted, all data and configurations within the container will also be lost. If you run a container from the image again, all data will be in the initial state. Therefore, for database containers, to prevent data loss due to the container's demise or damage, persistent storage of data is required. This can be achieved by specifying the -v parameter when running docker run. For example, the following command will specify storing all data files of openGauss on the host machine at /enmotech/opengauss. The -u root parameter is used to specify that the script is executed as the root user when the container starts, otherwise, there will be permission issues in creating the data file directory.
Note: If using podman, there will be a target path check, and the target path on the host machine needs to be created in advance.
console$ mkdir -p /enmotech/opengauss $ docker run --name opengauss --privileged=true -d -e GS_PASSWORD=Secretpassword@123 \ -v /enmotech/opengauss:/var/lib/opengauss -u root -p 15432:5432 \ enmotech/opengauss:latest
Create Master-Slave Replication openGauss Container
- Pull the container image
- Run the script https://github.com/enmotech/enmotech-docker-opengauss/blob/master/create_master_slave.sh, enter the required parameters as prompted, or directly use the default values to automatically create two containers with a one-master-one-slave architecture of openGauss.
The above script has multiple custom parameters, the following are the parameter names (explanation) [default value].
OG_SUBNET(Container subnet) [172.11.0.0/24]
GS_PASSWORD(Define database password) [Enmo@123]
MASTER_IP(Master database IP) [172.11.0.101]
SLAVE_1_IP(Slave database IP) [172.11.0.102]
MASTER_HOST_PORT(Master database service port) [5432]
MASTER_LOCAL_PORT(Master communication port) [5434]
SLAVE_1_HOST_PORT(Slave database service port) [6432]
SLAVE_1_LOCAL_PORT(Slave communication port) [6434]
MASTER_NODENAME(Master node name) [opengauss_master]
SLAVE_NODENAME(Slave node name) [opengauss_slave1]
Usage Example
Pull the Image
console# docker pull enmotech/opengauss:latest
Get and Run the Script to Create Master-Slave Containers
