Connecting Sources

Use the environment variable OR_SOLUTION_GALLERY to specify the sources from which the Solution Gallery loads its content.

Each specified source must be a URL pointing to a ZIP file. This ZIP file must contain a valid Solution Gallery structure.

If OR_SOLUTION_GALLERY is not set, the Solution Gallery provided by inray is automatically available.

Typical Use Cases​

  • Integration of official, publicly available solutions
  • Provision of internal company solutions via a dedicated web server or an artifact repository
  • Combination of multiple sources, such as official and internal solutions

Specifying Multiple Sources​

You can specify multiple sources by separating the URLs in OR_SOLUTION_GALLERY with semicolons.

OR_SOLUTION_GALLERY=https://example.com/solution-gallery-1.zip;https://example.com/solution-gallery-2.zip

If you want the solutions provided by inray to remain available in addition to your own Solution Gallery, specify both URLs in the environment variable:

OR_SOLUTION_GALLERY=https://example.com/meine-solution-gallery.zip;https://github.com/OPC-Router/solutions/releases/latest/download/solutions.zip

The URL for the Solution Gallery provided by inray is:

https://github.com/OPC-Router/solutions/releases/latest/download/solutions.zip

Recommendations for Deployment​

Before integrating a source, verify the following:

  • The ZIP file is permanently accessible via the specified URL.
  • The structure it contains matches the expected Solution Gallery structure.
  • The solutions it contains are compatible with the OPC Router version in use.
  • The descriptions and parameters are understandable to the intended users.

If you only want to use solutions internally, creating your own source is usually the best approach. This allows you to centrally maintain shared templates and make them available consistently to multiple project engineers.
