Replaces inline Portainer installation with a separate script when requested. Updates install-docker.sh to call the new script, improving maintainability and logging.
Updated default machine type to Q35 and improved user messaging for machine selection. Enhanced Docker and base package installation with DNS configuration and fallback to cloud-init if installation fails. Refactored Portainer installation logic and improved status reporting for Docker setup.
Introduces misc/cloud-init.sh, a universal Cloud-Init helper library for Proxmox VM scripts. Refactors vm/docker-vm.sh to source the new Cloud-Init library, reorganizes variable initialization, improves OS and configuration selection logic, and enhances user interaction for VM creation. Also adds a backup of the previous docker-vm.sh as docker-vm.sh.bak.
Introduces logic to detect SSH public keys on the host and prompt the user to use them for root login in new VMs. If no keys are found or declined, prompts for a root password with confirmation. Refactors authentication setup into a dedicated function and updates VM creation flow to configure authentication accordingly.
Corrected an extra quote in SNIPPET_PATH assignment and increased the whiptail radiolist width from 60 to 70 for better display in the Docker VM setup script.
Introduces a storage selection dialog for Cloud-Init snippets when running on Proxmox VE 9 in cloudinit install mode. Refactors storage selection for VM disks and improves error messages for missing storage types.
