OptScale components and architecture

Getting started

Minimum hardware requirements for OptScale cluster: CPU: 8+ cores, RAM: 16Gb, SSD: 150+ Gb.

NVMe SSD is recommended.
OS Required: Ubuntu 20.04.
The current installation process does not work on Ubuntu 22.04

Installing required packages

Run the following commands:

sudo apt update ; sudo apt install git python3-venv python3-dev sshpass

Pulling optscale-deploy scripts

Clone the repository

git clone https://github.com/hystax/optscale.git

Change current directory:

cd optscale/optscale-deploy

Preparing virtual environment

Run the following commands:

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Kubernetes installation

Run the following command: comma after ip address is required

ansible-playbook -e "ansible_ssh_user=<user>" -k -K -i "<ip address>," ansible/k8s-master.yaml

where - actual username; - host ip address, ip address should be private address of the machine, you can check it with

ip a

If your deployment server is the service-host server, add "ansible_connection=local" to the ansible command.

Creating user overlay

Edit file with overlay - optscale-deploy/overlay/user_template.yml; see comments in overlay file for guidance.

Cluster installation

run the following command:

./runkube.py --with-elk  -o overlay/user_template.yml -- <deployment name> <version>

or if you want to use socket:

./runkube.py --use-socket --with-elk  -o overlay/user_template.yml -- <deployment name> <version>

deployment name must follow the RFC 1123: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/

version:

• Use hystax/optscale git tag (eg: 2023110701-public) if you use optscale public version.
• Use your own tag version if you build your optscale images (eg: latest).

please note: if you use key authentication, you should have the required key (id_rsa) on the machine

Cluster update

Run the following command:

./runkube.py --with-elk  --update-only -- <deployment name>  <version>

Get IP access http(s):

kubectl get services --field-selector metadata.name=ngingress-nginx-ingress-controller

Troubleshooting

In case of the following error:

run the following command to reset k8s and retry the installation command:

sudo kubeadm reset -f
ansible-playbook -e "ansible_ssh_user=<user>" -k -K -i "<ip address>," ansible/k8s-master.yaml

In case of the following error during cluster initialization:

requests.exceptions.ConnectionError: HTTPConnectionPool(host='172.22.24.157', port=2376): Max retries exceeded with url: /v1.35/auth (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f73ca7c3340>: Failed to establish a new connection: [Errno 111] Connection refused'))

check the docker port is opened:

sudo netstat -plnt | grep 2376

and open port in docker service config:

sudo nano /etc/systemd/system/docker.service

add this line (do not dorget to close docker port after installing Optscale)

ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2376

then reload config and restart docker

sudo systemctl daemon-reload
sudo service docker restart

Roadmap

• Cost plugin for MLflow, WanDB, and neptune.ai
• Integration with Optuna to optimize Reserved Instance and other hardware parameter usage
• Model versioning
• Better hardware selection recommendations based on usage patterns and algorithms
