          Description

          HI, i'm trying to use orion on a localhost. I installed is as follows:
          mongo:
          image: mongo:3.4
          command: --nojournal
          orion:
          image: fiware/orion
          links:

          • mongo
            ports:
          • "1026:1026"
            command: -dbhost mongo -corsOrigin __ALL

          and i used the command: docker-compose up
          this solved my problems with the get method, but other operations like post
          are returning me control-access-allow-header.
          How do i solve this problem?

          I'm using: javascript, jQuery.

          orion is installed: localhost:1026
          my aplication: localhost:63342

          Function post->

          function postEntities() {
          var settings = {
          "async": true,
          "url": "http://localhost:1026/v2/entities/",
          "method": "POST",
          "headers":

          { "content-type": "application/json", "cache-control": "no-cache" }

          ,
          "data": "{\"id\": \"2\", \"type\": \"teste\", \"nome\":
          {\"value\": \"Weslan\", \"type\": \"text\"}}"
          }

          $.ajax(settings).done(function (response)

          { console.log(response); }

          );
          }

            Dear user,

            I've tested your example, and I think the error you can be observing is: "Request header field cache-control is not allowed by Access-Control-Allow-Headers in preflight response." — This means that you should remove your "cache-control": "no-cache" and the request can be made. This is related to the javascript and the navigator, not to Orion.

            Please, consider using a volume for data in your MongoDB. Docker filesystem doesn't behave well with databases.

            Regards,
            José Ignacio.
