[Bug]: Swagger and openapi.json endpoints use the "localhost" path

[martkaczmarek]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

If we go to /api/docs/webjars/swagger-ui/index.html, the Swagger "Computed URL" always says http://localhost:3000/. Because of that, when clicking Try it out button, it tries to make queries against http://localhost:3000/, which may not be accessible from the client.

Same "localhost" config is seen in the /api/docs/openapi.json (I'm assuming that's where Swagger is getting the path from)

Expected Behavior

Swagger should use a proper api endpoint with external address.

Steps to reproduce

Make Swagger use the "external URL" path configured in ENV variables, instead of Localhost,

Environment

Docker compose multi image
v2.5.3
