Serverless architectural design for IoT systems

Prerequisites

1. Install Docker CE for Ubuntu here
2. Install Docker CE for Raspbian here
3. Install faas-cli. Instructions here
4. Python3 installed with the yml module (this is used to create the configuration files)

Basic Instalation

1. Template for my_rig_config.json

{
    "name": "pi001",
    "maxCapacity": 1001,
    "thing": true,
    "localUrl": "http://192.168.78.1",
    "localPort": 8080,

    "serverUrl": "http://192.168.78.130",
    "serverPort": "8080",
    "prometheusPort":9090,
    "write_timeout": 10,
    "read_timeout": 10,
    "mongo": "openfaas-db-mongodb"

}

2. Clone the openfaas repository

$ git clone https://github.com/openfaas/faas && \
  cd faas && \
  git checkout 0.7.7 && \
  cd ..

2. Initiate a docker swarm. In some cases, the flag --advertise-addr might be needed to specify the advertised address.

$ sudo docker swarm init

3. Deploy faas and remove unnecessary functions that come preinstalled.

$ sudo ./deploy_faas.sh

4. Continue instalation process process for IoT swarm or Cloud swarm

(Cont.) Instalation for local swarm (IoT)

1. Create a mongodb Docker Service

$ docker service create --network=func_functions --name openfaas-db-mongodb --publish 27017:27017 mongo mongod

2. Create configuration files

$ python3 create_my_functions.py sample-functions/stack.yml

3. Deploy my functions.

$ sudo ./deploy_my_functions.sh

(Cont.) Instalation in the cloud swarm (Server)

1. Create configuration files

$ python3 create_my_functions.py sample-functions/stack.yml

2. Deploy my functions.

$ sudo ./deploy_my_functions.sh --server
