Install a flow runtime

A flow is executed in the flow runtime environment. It can be installed as a single Docker container or as a Windows service. A flow runtime can run multiple flows. Flows can be updated/added without re-starting the container/service nor affect other flows.

The flow runtime uses an integrated MQTT Broker that covers publish/subscribe communication patterns. The node also employees a built-in HTTP-Server and supports full-duplex communication over websockets.

Hardware requirements

• CPU: 64-bit x86 or 64 bit ARM

• RAM: Minimum 500MB free (in addition to OS and Docker requirements)

• Disk: Minimum 300MB free (in addition to OS and Docker requirements)

Software requirements

The flows node is provided as a Linux Docker container or as a Windows service installer.

Both community (CE) and enterprise (EE) editions of Docker are supported. The flow runtime software runs on top of .NET 6 (included in the Docker container and the Windows service installer).

Network requirements

For connecting your flow runtime to your Flow manager instance, you need access to *.connect.aveva.com via port 443 (HTTPS).

If running the flow manager instance on prem, adjust the URL accordingly.

Linux operating systems (Docker)

Almost any Linux distribution with a kernel version of 3.10+ should work as a platform for running the flow runtimes.
