WinCC OA on Docker, Dockerfiles and Howto’s…

This repository on Github contains Dockerfiles and samples to build Docker images for WinCC OA products.

Build Docker Image

Download and unzip the CentOS WinCC OA rpm’s to the centos/software directory.

Only put those WinCC OA rpm’s into the directory which you want to have installed in your image. For a minimum image you only need the base packag of WinCC OA.

WinCC_OA_3.16-base-rhel-0-17.x86_64.rpm

Build your WinCC OA Docker image with:

docker build -t winccoa:3.16 .

WinCC OA Project in a Container

The project should be mounted on /proj/start as a volume to your docker container.

And you may also mount a shield file to your docker container.

Example how to startup a WinCC OA project in a container:

docker run -d  
  --name winccoa  
  --hostname winccoa-server  
  -v ~/shield.txt:/opt/WinCC_OA/3.16/shield.txt  
  -v /proj/DemoApplication_3.16:/proj/start  
  -p 5678:5678  
  winccoa:3.16

WinCC OA Gedi in a Container

To start a WinCC OA client application like a Gedi or a User-Interface you have to adapt your config file so that the proxy settings point to the WinCC OA server container. You can just create a copy of your config file (e.g. config.ui) and adapt the settings.

[general] 
data = "winccoa-server" 
event = "winccoa-server" 
mxProxy = "winccoa-server <your-docker-host-name>:5678 cert"

Then you can startup a Gedi/Ui with:

docker run --rm  
-e DISPLAY=$DISPLAY  
-v /tmp/.X11-unix:/tmp/.X11-unix  
-v /proj/DemoApplication_3.16:/proj/default  
-v /proj/DemoApplication_3.16/config/config.ui:/proj/default/config/config  
winccoa:3.16  
WCCOAui -autoreg -m gedi -proj default

Sure you can also use a copy of your project directory (or a git checkout if you use git) and adapt the config file.

Start Project Administration as Container

With the Project Administration you can create a new project in the /proj directory.

docker run -ti --rm 
-e DISPLAY=$DISPLAY 
-v /tmp/.X11-unix:/tmp/.X11-unix 
-v /proj:/proj 
winccoa:3.16 
WCCOAui -projAdmin

Distributed Managers and Kubernetes

For sure what we have done with the Gedi can also be done with Control-Managers and Drivers. And in theory that can also be done with Kubernetes and so you can run your SCADA project in a Kubernetes Cluster.
