packer-proxmox-templates

Proxmox Ubuntu cloud-init image built with Packer

Changes to the original repository:

• Added functionality to pass cloud-config with an additional ISO image instead of using Packer's web server.
• Implemented the use of a bastion SSH host (PVE node) to access the VM SSH server. Useful when VM is behind a NAT.
• Enabled the usage of the local SSH agent to access the bastion SSH host.
• Added a .devcontainer packer image and a wrapper script.
• Disabled unattended-upgrades service and enabled cloud-init for the produced template.
