You can use below code to add host variable into the json file

            // Add host to generated swagger file (swagger.json)
            options.AddServer(new OpenApiServer {
                Url = "http://{serverAddress}",
                Description = "IpTables Test Server",
                Variables = new Dictionary<string, OpenApiServerVariable>
                {
                    { "serverAddress", new OpenApiServerVariable {
                                                Default = "192.168.21.56:8080",
                                                Description = "Target Server Address" }
                    }
                }
            });

this options is for SwaggerGenOptions and you can set this in program.cs or startup.cs typically.
