- Things to know about WinCC OA
- Cybersecurity Beyond the Norm
- WinCC OA License Portal
  The WinCC OA License Portal provides a central platform for managing and transferring licenses. The video series covers basic functions, license transfer, clearing of old inventories, as well as the provisioning and removal of licenses.
- Docker Support
  Docker serves as an innovative platform designed to streamline the entire lifecycle of software applications, from development to deployment and execution. These videos show how to use WinCC OA within a Docker container.
  - What is Docker?
    This topic introduces Docker fundamentals - what Docker is, how it compares to virtual machines, and why containers improve portability, efficiency, and scalability. You’ll learn about images; container and license management for WinCC OA containers; Docker Compose; health checks; and streamlined updating and patching. It also outlines core Docker components (client, daemon, images/registry, containers, volumes, networks) and basic commands like docker ps.
  - Docker Image
    Docker images are prepackaged application environments that act as templates for running containers. Because WinCC OA does not yet provide an official image (patch-release images are planned), this topic explains how to build a custom WinCC OA Docker image by extracting the required Debian packages, adapting the Dockerfile and entry point script, and building the image from the local folder.
  - Container Management & Licensing?
    Manage Docker containers with Portainer or the CLI to list, start/stop, inspect, view logs, and open interactive shells. Start a WinCC OA OA container by selecting the image, mapping required ports (e.g., 8443), setting environment variables for the project and license server, and using volumes to persist data across restarts. If the license server hosts multiple containers, set the UCM container serial in the project configuration to ensure a valid license.
  - Running Multiple Containers
    Use Docker Compose to define and persistently start multiple containers from a YAML file rather than running individual Docker commands. This topic demonstrates orchestrating a WinCC OA server with local and cloud PostgreSQL services and a DMZ web server, configuring images, volumes, networks, ports, and environment variables, and managing lifecycle with compose commands (up/down, build, detach, force-recreate) and required volume permissions.
  - Health Check
    Configure a Docker health check for the WinCC OA container so the remote web server waits until the service is ready instead of retrying on startup. A WinCC OA_health checks script periodically evaluates manager status and internal error state against a defined threshold (for example, fewer than 100 failure points) to mark the container healthy, which Docker Compose can enforce using depends_on with the service_healthy condition.
  - Update
    Explains how to perform a smooth patch update of WinCC OA using Docker Compose. Build the updated image (for example, patch 6) from your docker-compose YAML and restart the Compose project to apply the changes with minimal downtime.

Health Check

Configure a Docker health check for the WinCC OA container so the remote web server waits until the service is ready instead of retrying on startup. A WinCC OA_health checks script periodically evaluates manager status and internal error state against a defined threshold (for example, fewer than 100 failure points) to mark the container healthy, which Docker Compose can enforce using depends_on with the service_healthy condition.

Transcript

Docker containers can report their health status. When our remote web server starts, the WinCC OA server is not yet ready to accept connections. As a result, the web server retries the connection after 20 seconds.

If the WinCC OA container includes a health check that indicates when the service is ready, the web server container could wait for it before attempting start.

The WinCC OA_health checks script is executed regularly to monitor the state of the WinCC OA managers using PMO. Additionally, it evaluates the internal WinCC OA error state via the docker health checked at ctrl script ensuring the system remains below a defined threshold e.g. fewer than 100 failure points to be considered healthy in a docker composed file.

This health check can be integrated using the depends underscore on directive with a condition service option. This allows the remote web server container to wait until the WinCC OA service is confirmed to be healthy before starting.

As a result, the web server container now correctly waits to start until the WinCC OA server is fully ready and marked as healthy.
