Deployment and Maintenance / System Requirements

Before installing DataFlux Func, please ensure that 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 above, macOS and Windows are not supported
  • Clean system (no operations performed after installing the operating system except for network configuration)
  • Open port 8088 (this system uses port 8088 by default. Please ensure firewall, security group, and other configurations allow inbound access to 8088)
  • When using an external MySQL, the MySQL version must be 5.7 or above, with the innodb_large_prefix parameter enabled, and the database encoding set to utf8mb4
  • When using an external Redis, the Redis version must be 5.0 or above, with at least 1 GB of available memory, non-clustered version

Note on certain cloud platform auto-installed plugins

Some plugins automatically installed by cloud platforms may consume significant resources themselves. The system configuration should be appropriately increased.

Detailed operating system compatibility

For detailed operating system compatibility test results, please refer to Tested Operating System 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. The installation package itself includes the Docker installation package and will automatically install Docker during installation.

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

  • The Docker Swarm initialization command is: sudo docker swarm init

If the machine has multiple network cards, the network card needs to be specified in the above initialization command.

  • Users with multiple network cards are advised to install Docker and initialize Docker Swarm themselves.
  • The Docker Swarm initialization command specifying a network card is: sudo docker swarm init --advertise-addr={network card name} --default-addr-pool={default address pool}
  • The list of network cards on the machine can be queried using ifconfig or ip addr.
  • Ensure the default address pool does not conflict with the local network subnet.

Snap version of Docker is not supported

DataFlux Func does not support running on the Snap version of Docker.

docker swarm init in the automatic installation script

In the automatic installation script, when performing docker swarm init, the --advertise-addr and --default-addr-pool parameters are set to 127.0.0.1 and 10.255.0.0/16 respectively.

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's operation depends on Docker Swarm. Some older Linux distributions may not support the newer version of Docker, preventing the installation of this system.

For "Tested Environment":

  • Virtual Machine: All use official ISO images, deploying DataFlux Func directly after installation.
  • Alibaba Cloud: All use ECS public images, deploying DataFlux Func directly after ECS startup.
  • Raspberry Pi: All use ISO images provided by the official website (ARM 64-bit operation), deploying DataFlux Func directly after startup.

For "Tested Result":

  • Compatible: Indicates that after installing/creating the host, the installation script can be run directly to complete the installation without any additional operations.
  • Conditionally Compatible: Indicates that after installing/creating the host, the installation script cannot be run directly; additional operations are required before executing the installation script.
  • Incompatible: Indicates that the installation script cannot execute correctly in this environment, but you can use the image file to handle it yourself.

Test Results

The operating systems listed below have been tested and passed on cloud platforms or virtual machines. Those not listed are not necessarily incompatible.

Requires 64-bit system

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

Windows and macOS are not supported

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