Hello Team,

I am facing this issue - can you please help me?

Below are the steps I followed -
sudo apt update
sudo apt install python3-pip sshpass git python3-virtualenv python3 python3-venv python3-dev -y

git clone https://github.com/optscale/optscale.git
cd optscale/optscale-deploy

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

MY_USER=$(whoami)
MY_IP=$(hostname -I | awk '{print $1}')

ansible-playbook -e "ansible_ssh_user=$MY_USER" -e "ansible_connection=local" -i "$MY_IP," ansible/k8s-master.yaml

Error -
