vainia / RABBIT_MQ_W

Overview

Main target is to manage tools which helps user to edit strings. Service replacing chars in text(published into it by JSON message) with defined function in performer.py.

Message must strictly adopted to JSON template:

{
   'NAME':'message'
}

Where 'NAME' is static keyword required for micro-service(hereinafter "MS") and 'message' - any string text defined by user.

As output we got updated log.log file placed in MS primary folder with '!' to '?' first appeared letter replaced in JSON 'message' which appends after data and time of current access and wrote on it.

Requirements

• pika==0.11.2 (because we need sometimes to feed our python with small rodents)

Pika has used for supplying pure-Python implementation of the AMQP 0-9-1 protocol including RabbitMQ’s extensions. That module gives us ability to perform any manipulations with RabbitMQ.

Run

All commands will be perform in terminal (docker must be installed).

First of all you need to raise up RabbitMQ server with command:

docker run -d --hostname my-rabbit -p 0.0.0.0:5672:5672 -p 0.0.0.0:15672:15672  --name some-rabbit -e RABBITMQ_DEFAULT_USER=user_name -e RABBITMQ_DEFAULT_PASS=user_password rabbitmq:3-management

Ports ASMP:5672 and HTTP:15672 are defaults for backend(functional) and frontend(web) accordingly. 0.0.0.0 means that RabbitMQ will listen for all hosts.

If you want to run single MS just run build.sh placed in primary folder titled with MS name.

Configuration

File config.py maintain configurations for MS:

SET = {
    'port':'5672', #default port
    'server':'0.0.0.0', #rabbit-mq server ip adres
    'name':'user_name', #name required for connection to server
    'passwd':'user_password', #password required for connection to server
    'queue_current':'RMQ-L-W', #name of the current queue, where initial JSON being preserved
    'queue_above':'' #name of the next queue, where JSON sends after processing
}

Everything above(excluding queue set and server ip) must be exactly the same as defined in command raising RabbitMQ server.
