The 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
Run the following commands:
sudo apt update; sudo apt install python3-pip sshpass git python3-virtualenv python3.9
Clone the repository
git clone https://github.com/hystax/optscale.gitChange current directory:
cd optscale/optscale-deploy
Run the following commands:
virtualenv -p python3.9 venv
source venv/bin/activate
pip install -r requirements.txt
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 <user> - actual username; <ip address> - 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.
Edit file with overlay - optscale-deploy/overlay/user_template.yml; see comments in overlay file for guidance.
Pay attention to "service_credentials" parameter, as OptScale uses it to retrieve cloud pricing data for recommendations calculation.
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: latest) if you use optscale public version.
- Use your own tag version if you build your optscale images (eg: local).
please note: if you use key authentication, you should have the required key (id_rsa) on the machine
Check the state of the pods using kubectl get pods command.
When all of the pods are running your OptScale is ready to use. Try to access it by https://<ip address>.
Run the following command:
./runkube.py --with-elk --update-only -- <deployment name> <version>
kubectl get services --field-selector metadata.name=ngingress-nginx-ingress-controllerIn case of the following error:

run the following command to reset k8s and retry the installation command:
sudo kubeadm reset -f

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 forget 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
