This script installs kube-proxy on the nodes designated as worker nodes. The script creates a kube-proxy installation script from a template - prefilling the clusterCIDR address from the environment variables prior to copying. The script then copies the kube-proxy setup script to each worker node, and then executes via sudo the script on each node. This is done serially - could potentially be with just one loop though. The kube-proxy systemd service script is created and filled with the correct configuration parameters. The configuration is filled and then systemctl reloaded. The kube-proxy binary is downloaded and the service is started and enabled.
