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 git python3-venv python3-dev sshpass
Clone the repository
git clone https://github.com/hystax/optscale.gitChange current directory:
cd optscale/optscale-deploy
Run the following commands:
python3 -m venv .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 - 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.
Edit file with overlay - optscale-deploy/overlay/user_template.yml, see comments in overlay file for guidance.
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 required key (id_rsa) on the machine
Run the following command:
./runkube.py --with-elk --update-only -- <deployment name> <version>

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:

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:https:// -H tcp:https://0.0.0.0:2376
then reload config and restart docker
sudo systemctl daemon-reload
sudo service docker restart
