Fogify in Docker-compose

Execution

To ease the installation of Fogify, we created a docker-compose file that contains a dockerized version of Fogify connected with a Jupyter server, which is used as a web-based GUI. Since, the Fogify and Jupyter stack is provided as dockerized services, we only need to run the following command at the swarm master node.


sudo docker-compose -p fogemulator up
In order to open the web interface of Jupyter, you have to find the output of the ui service where the system outputs the url and the token

Jupyter Notebook

For instance, in previous output we can open the Jupyter interface with the following url: 


http://127.0.0.1:8888/?token=1cd2e914cd03e76d551a666cb0a8dcdb6361bc29ddf54eed

If we have more nodes in the cluster, we have to execute the following command on every node.


sudo docker-compose -p fogemulator up agent cadvisor

For both modes, users should provide a set of parameters to compose file (written in .env file), specificaly: 


MANAGER_NAME=.... #The name of the swarm master node
MANAGER_IP=192.168.1.1 #The IP of the swarm master node
HOST_IP=192.168.1.1 #The IP of the host
CPU_OVERPROVISIONING_PERCENTAGE=... # A percentage of cpu over provisioning 0-100
RAM_OVERPROVISIONING_PERCENTAGE=... # A percentage of memory over provisioning 0-100 
CPU_FREQ= ... # The frequency of the underlying CPU 
VERSION=.... #The version of Fogify

Docker-compose file

Next, we have the docker-compose file of Fogify system. The fogify and fogify-jupyter are images upload to docker-hub.
