openCOT

openCoT is a Cloud Infrastrcuture manager for FaaS clouds and is initially designed for IoT applications; Although it can be used in other cases too. The architecture behind this platform is well documentd in the following paper: https://arxiv.org/abs/1901.00302

Installation

Controller

1) Installing Docker engine

Install docker-cl package on the linux based node.

2) Install Python 3 on the Node computer

sudo apt-get install python3
sudo apt-get install python3-pip

4) Install the PyZMQ and Docker client for Python

pip install docker
pip install pyzmq

5) Copy the Controller folder to the Controller computer

Node

1) Installing Docker engine

Install docker-cl package on the linux based node.

2) Enable Docker to limit containers

Open the grub configuration file in a text editor

gedit /etc/default/grub

Add the following line

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

Save changes

Update the grub configuration

sudo update-grub

Restart the docker engine

3) Install Python 3 on the Node computer

sudo apt-get install python3
sudo apt-get install python3-pip

4) Install the PyZMQ and Docker client for Python

pip install docker
pip install pyzmq

5) Copy the Node folder to the Node computer

Test

On the Controller computer run Exec-SimpleController.py (in the Controller folder).

sudo -s
python3 SimpleController.py

You should see the output of the Controller's intialization followed by: Press enter to start...

In this moment, on the Node computer, run Exec-SimpleNode.py.

sudo -s
python3 SimpleController.py

Enter 'cluster1' and the IP of the Controller computer. And wait for the Node script to load everything.

Now, go back again to the Controller and press Enter. A successful installation results in the execution of the hellocot function each 1 second on the Node.
