Configuration using environment variables

As environment variables do not have any hierarchical order, the tia® Viewer parameters must be qualified completely:

TIA_DESTINATIONS_SAPHTTP_HOST

Not all environments support the parameter name scheme for environment variables.

To convert a parameter name to an environment variable name follow these rules:

Replace dots (.) with underscores (_).
Remove any dashes (-).
Convert to uppercase.

Example for a docker-compose file with configuration using environment variables:

version: '3'
services:

  tiaviewer:
    container_name: tiaviewer
    image: images.docker.kgs-cloud.de/tia-viewer/archivelink-oidc:latest
    ports:
      - "8080:8080"
    environment:
      TIA_DESTINATIONS_SAPHTTP_HOST: contentservevr.kgs.local
      TIA_DESTINATIONS_SAPHTTP_PORT: 8090
      TIA_INSTANCES_DEFAULT_SAP_URL: https://sapServer:50000/tia/tia_viewer?sap-client=250
      TIA_INSTANCES_DEFAULT_SAP_USERNAME: secuser
      TIA_INSTANCES_DEFAULT_SAP_PASSWORD: s3cret
    volumes:
      - ./viewerlicense.json:/application/config/license/viewerlicense.json
