Edge++: Deployment

Edge++ Deployment on Rails setup

The configuration Github repository can be found here [1] This repository is a bunch of shell scripts that will help you orchestrate dockerized environment. This environment is served using docker-compose.

For booting setup we have to do ./boot.sh and to bring it down ./shutdown.sh

Configuration:

Couple of fields to be set up in .env file.

• LICENSE_KEY: License key of account on boarded on Datonis
• NUMBER_OF_INPUT_QUEUES: Degree of parallelism at which we want to process our event stream.

Basic building blocks of the architecture in terms of dockers are as follows:

Name	Docker Image	Purpose
redis	redis:6.0.3-buster	Redis server
mongo	mongo:4.2.7-bionic	MongoDB for master data caching
factory-server	altizon/factory	Factory Server to provide operator screens using FaasInfra
sidekiq	altizon/factory	Sidekiq running asynchronous tasks
factory-rake	altizon/factory	There will be N no of instances of this kind listening to their respective input queues.
factory-function-cache	altizon/factory	Function Task schedular to start master data caching like account and user preferences to local MongoDB from production
update_number_of_queues	altizon/factory	Updating __number_of_input_queues__ in Redis on boot
wget_call	altizon/factory	Calling first API request to server initiating asset compilation

Data Persistance

• The data being saved in MongoDB is a volume mounted on docker. Hence, it is safe to assume that your data will persist in MongoDB across boots of Edge++.
• For Redis we use Redis Persistance to ensure Redis maintains its state across boots. We use .aof files for saving our state.

  • Virtualbox "port forward" from Guest to Host
• Setting up redis container inside vm and accessing it via host.
  • Configure and Run a Docker Container for Redis and Use it for Python
  • Network type of vm - NAT
  • Redis config - bind 0.0.0.0:port instead of 127.0.0.1
  • Start the container and run Redis
  • Port forwarding of vm- host: <redis-port> - guest: <redis-port>
  • This will make redis available on localhost:port
  • Ref  -  Cannot get or set to Redis on Vagrant guest from host due to "Error: Connection reset by peer"
