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 >= 4GB
  • Disk space >= 20GB
  • Network bandwidth >= 10Mbps
  • Operating system: 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 configuring the network)
  • Port 8088 open (the system uses port 8088 by default, ensure that the firewall, security group, etc., allow inbound access to 8088)
  • When using an external MySQL, MySQL version must be 5.7 or above, with innodb_large_prefix parameter enabled, and database encoding set to utf8mb4
  • When using an external Redis, Redis version must be 5.0 or above, with at least 1 GB of available memory, non-cluster version

Note on certain cloud platform plugins

Some plugins automatically installed by cloud platforms may consume significant resources, so system configurations should be appropriately increased.

Detailed OS compatibility

For detailed OS compatibility test results, refer to Tested OS Compatibility

For installation on Raspberry Pi, refer to the following articles:

2. Software Preparation

This system runs based on Docker Stack, and the installation package includes Docker and will automatically install it during setup.

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

  • Docker Swarm initialization command: sudo docker swarm init

If the machine has multiple network cards, specify the network card in the initialization command.

  • For machines with multiple network cards, it is recommended to manually install Docker and initialize Docker Swarm.
  • Docker Swarm initialization command with specified network card: sudo docker swarm init --advertise-addr={network card name} --default-addr-pool={default address pool}
  • List network cards using ifconfig or ip addr
  • Ensure the default address pool does not conflict with the local network subnet.

Snap version of Docker not supported

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

docker swarm init in the automatic installation script

The automatic installation script uses the following parameters for docker swarm init: --advertise-addr=127.0.0.1 and --default-addr-pool=10.255.0.0/16.

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

3. Tested OS Compatibility

This system relies on Docker Swarm, and some older Linux distributions may not support the latest Docker version, making it impossible to install this system.

For "tested environments":

  • Virtual machines: Official ISO images were used, and DataFlux Func was deployed directly after installation.
  • Alibaba Cloud: ECS public images were used, and DataFlux Func was deployed directly after ECS startup.
  • Raspberry Pi: Official ISO images (ARM 64-bit) were used, and DataFlux Func was deployed directly after startup.

For "tested results":

  • Compatible: Indicates that the installation script can be run directly after the host is installed/created, without any additional steps.
  • Conditionally compatible: Indicates that additional steps are required before running the installation script after the host is installed/created.
  • Incompatible: Indicates that the installation script cannot be executed correctly in this environment, but you can handle it manually using the image file.

Test results

The listed operating systems were tested on cloud platforms or virtual machines, and passed the tests. Unlisted systems are not necessarily incompatible.

64-bit system required

DataFlux Func requires a 64-bit system. Official Raspberry Pi OS also needs to run in ARM 64-bit mode.

Windows and macOS not supported

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