Docker-Image
Docker-Images sind vorgefertigte Anwendungsumgebungen, die als Vorlagen zum Ausführen von Containern dienen. Da WinCC OA noch kein offizielles Image bereitstellt (Patch-Release-Images sind geplant), wird in diesem Thema erläutert, wie ein benutzerdefiniertes WinCC OA-Docker-Image erstellt wird, indem die erforderlichen Debian-Pakete extrahiert, das Dockerfile und das Entrypoint-Skript angepasst und das Image aus dem lokalen Verzeichnis gebaut wird.

A Docker image is a prepackaged software bundle that includes the application, its runtime components, required libraries, and tools, all in a preconfigured state.
These images act as templates for running containers.
Depending on the use case, Docker images offer the flexibility needed for different environments. For example, you could pull the official Postgrql version 16 image to run a database instance or use a standardized WinCC OA container that runs your specific project with your license already configured.
Currently, WinCC OA does not offer an officially maintained Docker image. However, in future, we plan to provide images with patch releases. In the meantime, you can create a custom WinCC OA Docker image tailored to your needs by following these steps.
- Download and extract the necessary Debian packages.
- Adapt the Docker file and entry point script according to your requirements.
- Build the image using the selected installation packages.
I have
already downloaded WinCC OA 3.20 patch 4 and extracted the Debian
packages by running the command docker build -t followed by the image name and a
dot. A docker image will be created from the packages of the current local
folder.
