Requirements for run Krios

Currently, to run Krios, you need at least 6 ubuntu nodes that can all talk to each other. Amongst these nodes, one node will be Krios orchestrator, one will be the client and the rest will be Krios satellite nodes.

Installation steps:

• Recursively pull the emulator submodule using `git submodule update --init --recursive.
• Install Go, Docker, Kubernetes, python3, and pip from the official sources. This needs to be done on all the nodes. If you are using cloudlab nodes, you can use this script to install all the necessary software on all the cloudlab nodes.
• Install all the requirements listed in requirements.txt using pip install -r requirements.txt. This needs to be done on the orchestrator and client.

Steps to run:

• On the client node (alphabetically the last node), run the client script using python script-client.py from the krios_daemon directory.
• On the orchestrator node (alphabetically the first node), setup the cluster using kubeadm and install a CNI.
• Deploy the Krios scheduler and the Krios Controller from the yaml files provided in the yamls directory.
• Install the nginx pod from yamls directory using kubectl apply -f nginx_pod.yaml. Ensure that the client location specified in the client and server scripts matches the one provided in this yaml file.
• On the orchestrator, run the main script using python script-main.py from the krios-emulator directory.

Post this, you should start seeing the client getting response, and also logging the latency values.
