Deployment and Maintenance / System Requirements

Before installing DataFlux Func, please make sure the environment meets the following conditions.

1. System Requirements

The host running DataFlux Func must meet the following conditions:

  • CPU cores >= 2
  • Memory capacity >= 4GB
  • Disk space >= 20GB
  • Network bandwidth >= 10Mbps
  • Operating system is Ubuntu 16.04 LTS / CentOS 7.2 or later, macOS and Windows are not supported
  • A clean system (after installing the operating system, no other operations have been performed except network configuration)
  • Open 8088 port (this system defaults to using the 8088 port, please ensure that firewall, security groups, etc., allow inbound access to 8088)
  • When using an external MySQL, the MySQL version must be 5.7 or higher, enable the innodb_large_prefix parameter and the database encoding must be utf8mb4
  • When using an external Redis, the Redis version must be 5.0 or higher, with at least 1 GB of available memory, non-cluster edition

Alibaba Cloud ECS CloudShield plugin

The Alibaba Cloud ECS CloudShield plugin consumes a significant amount of resources, so system configurations should be appropriately increased.

Detailed Operating System Compatibility

For detailed tested operating system compatibility results, refer to Tested OS Compatibility

If you wish to install on a Raspberry Pi, please refer to the following articles:

2. Software Preparation

This system runs based on Docker Stack, and the installation package itself already includes Docker installation files which will be automatically installed during setup.

Users can also manually install Docker and initialize Docker Swarm, then run the installation script. The installation script will automatically skip this step if it detects Docker is already installed.

  • Docker Swarm initialization command: sudo docker swarm init

If there are multiple network cards on the machine, you need to specify the network card in the above initialization command.

  • It is recommended for users with multiple network cards to manually install Docker and initialize Docker Swarm.
  • Docker Swarm network card specification initialization command: sudo docker swarm init --advertise-addr={network_card_name} --default-addr-pool={default_address_pool}
  • The list of local network cards can be queried through ifconfig or ip addr
  • Make sure the default address pool does not conflict with your local network subnet

Snap Edition of Docker Not Supported

DataFlux Func does not support running on the Snap edition of Docker

Automatic Installation Script's docker swarm init

During automatic installation, the parameters --advertise-addr and --default-addr-pool will be set to 127.0.0.1 and 10.255.0.0/16 respectively by the installation script.

Bash
1
docker swarm init --advertise-addr=127.0.0.1 --default-addr-pool=10.255.0.0/16

3. Tested Operating System Compatibility

This system relies on Docker Swarm to run, and some older Linux distributions may not support newer versions of Docker, making it impossible to install this system.

For "Test Environments":

  • Virtual Machines: All use official ISO images, deploying DataFlux Func immediately after installation.
  • Alibaba Cloud: All use ECS public images, deploying DataFlux Func directly after starting the ECS.
  • Raspberry Pi: All use official ISO images from the website (running ARM 64-bit), deploying DataFlux Func immediately after startup.

For "Test Results":

  • Compatible: After creating/installing the host, simply running the installation script completes the installation without any additional operations required.
  • Conditionally Compatible: After creating/installing the host, the installation script cannot be run directly; additional operations are needed before executing the installation script.
  • Not Compatible: The installation script cannot be correctly executed in this environment, but you can handle it using image files.

Test Results

The listed operating systems below indicate actual installations and successful tests on cloud platforms or virtual machines. Unlisted ones do not necessarily mean they are incompatible.

Requires a 64-bit System

DataFlux Func needs to run on a 64-bit system. The official Raspberry Pi OS also requires enabling ARM 64-bit mode.

Windows and macOS Not Supported

DataFlux Func does not support Windows or macOS. You can choose to install it in a virtual machine or cloud server.
