Hello,

I created a fig file which does the same as setup.sh but when I try to call the rest service it seems like the img_url is not passed correctly.

Fig file:

rabbitmq:
  image: tutum/rabbitmq
  dns: 8.8.8.8
  # ports:
  #     - "5672:5672"
  #     - "15672:15672"
  environment:
    - "RABBITMQ_PASS=1234"

openocr:
  image: tleyden5iwx/open-ocr
  dns: 8.8.8.8
  links:
    - rabbitmq
  ports:
    - "9292:9292"
  command: open-ocr-httpd -amqp_uri "amqp://admin:1234@rabbitmq/" -http_port 9292

openocrworker:
  image: tleyden5iwx/open-ocr
  dns: 8.8.8.8
  links:
    - rabbitmq
  command: open-ocr-worker -amqp_uri "amqp://admin:1234@rabbitmq/"

Curl request:

curl -v -X POST -H "Content-Type: application/json" -d '{"img_url":"http://bit.ly/ocrimage","engine":"tesseract"}' http://192.168.59.103:9292/ocr

It seems like the img_url is not parsed from request body

You should see something like the following output in your OCR_WORKER logs:

23:58:02.389856 OCR_WORKER: Creating new OCR Worker
23:58:02.390277 OCR_WORKER: Run() called...
23:58:02.390316 OCR_WORKER: dialing "amqp://xxx:yyy@162.222.178.49/"
23:58:17.427673 OCR_WORKER: got Connection, getting Channel
23:58:17.455394 OCR_WORKER: binding to: decode-ocr

and the fact that you are not seeing this tells me that the OCR_WORKER is either connecting to the wrong rabbitmq uri, or is trying to connect before its launched.

To test a workaround, can you add some "sleeps" somehow in your fig config for the OCR_WORKER? Make it sleep for 30s before trying to startup. I guess the long term fix might be to have a timeout and a retry loop in the go code when it connects to rabbit.

I think the log message "OCR_CLIENT: ocrRequest before: ImgUrl: ," is misleading, lets ignore that for now.

Once we get this working, I'll add the fig file to the repo/docs. Thanks for contributing that!

I mean, the fact that you are not seeing these two lines:

23:58:17.455394 OCR_WORKER: binding to: decode-ocr

I can add command in worker command: sleep 30;open-ocr-worker -amqp_uri ...

The 30 seconds delay was the problem. I figured it out and made a pull reqest #33 with fig configuration

I added a ticket to address the retry issue: #34, at which point we can remove the ugly workaround.

Also, do you have any instructions on how to use the fig files? (I've never used fig, but have heard a lot about it).

I will write in readme how to start with open-ocr with fig but first I would like to add stroke width preprocessor into fig configuration.
