General

General CENTRUM = Fronius Central User Management

CENTRUM is a server-based application that centrally manages the user settings
of several connected welding systems in a database.
The hardware or VM configuration required for this depends on the number of
devices to be managed.
The user is responsible for the operation of the hardware or VM, and for the con­figuration, licensing, and maintenance of the recommended operating system.

It is not intended for CENTRUM to be installed and operated on a single desktop
computer or system PC, for example in a production hall.

To ensure smooth operation, the setup of the server (hardware or VM), the design
of the network infrastructure, and administration should only be performed by
the user's IT department.

Link to the Docker engine Installation Instructions:

https://docs.docker.com/engine/install/

The following instructions are recommended for installing the Docker engine
on a Windows server:

https://docs.microsoft.com/en-us/virtualization/windowscontainers/quick­start/set-up-environment?tabs=Windows-Server

To start the Central User Management server, you must first create a container
for Central User Management.

The container uses a defined Docker volume. The Docker volume is required in
order to save the database independently of the container and thus enable serv­er updates to be carried out without any loss of data.

The container uses a HTTPS connection in order to ensure the highest possible
level of security during communication between the server and user.

In order to use HTTPS, copy the PFX or P12 certificate into the container as de­scribed below:

Run all of the following commands in the Shell of the operating system.

Run the following command to log into the Registry of Central User Manage-

1

ment:

docker login registry.pw.fronius.com --username 9432fea2-51d0-4450­a255-702bbe79d2be --password 6f7bda41-b0a2-48f3-b6a2-bbbb8ce754f4

Run the following command in order to create the container:

2

docker create --name centrum -p <https-port>:443 -p 4711:4711 -v
centrum-data:/<Container-Data-Folder-Path> -e ASPNETCORE
_URLS="https://+;http://+" -e ASPNETCORE_HTTPS_PORT=
<https-port> -e ASPNETCORE_Kestrel__Certificates__Default__
Password=<Certificate-Password> -e ASPNETCORE_Kestrel__
Certificates__Default__Path=<Certificate-Path-In-Container> -­restart=always registry.pw.fronius.com/centrum

Explanation of the command:

<https-port>
The Port via which the Website of Central User Management can be accessed ­always select Port 443, as this Port is stored on the welding systems and cannot
be changed from there

-p 4711:4711
Port mapping that is required for connecting to the welding systems

-v centrum-data:<Container-Data-Folder-Path>
The Docker volume where the data are stored.
