# VM Scripts Documentation (/vm)
|
|
|
|
This directory contains comprehensive documentation for virtual machine creation scripts in the `/vm` directory.
|
|
|
|
## Overview
|
|
|
|
VM scripts (`vm/*.sh`) create full virtual machines (not containers) in Proxmox VE with complete operating systems and cloud-init provisioning.
|
|
|
|
## Documentation Structure
|
|
|
|
VM documentation parallels container documentation but focuses on VM-specific features.
|
|
|
|
## Key Resources
|
|
|
|
- **[misc/cloud-init.func/](../misc/cloud-init.func/)** - Cloud-init provisioning documentation
|
|
- **[CONTRIBUTION_GUIDE.md](../CONTRIBUTION_GUIDE.md)** - Contribution workflow
|
|
- **[EXIT_CODES.md](../EXIT_CODES.md)** - Exit code reference
|

|
|
## VM Creation Flow
|
|
|
|
```

|---------|:---:|:---:|
|
|
| Isolation | Full | Lightweight |
|
|
| Boot Time | Slower | Instant |
|
|

|
|
## Quick Start
|
|
|
|
To understand VM creation:
|
|
|
|
1. Read: [misc/cloud-init.func/README.md](../misc/cloud-init.func/README.md)
|
|
2. Study: A similar existing script in `/vm`
|
|
3. Understand cloud-init configuration
|
|
4. Test locally
|
|
5. Submit PR
|
|
|
|
## Contributing a New VM
|
|
|
|
1. Create `vm/osname-vm.sh`
|
|
2. Use cloud-init for provisioning
|
|
3. Follow VM script template
|
|
4. Test VM creation and boot
|
|
5. Submit PR
|
|
|
|
## Cloud-Init Provisioning
|
|
|
|
VMs are provisioned using cloud-init:
|
|
|
|
```yaml
|
|
#cloud-config
|
|
hostname: myvm
|
|
timezone: UTC
|
|
|
|
packages:
|
|
- curl
|
|
- wget
|
|
|
|
users:
|
|
- name: ubuntu
|
|
ssh_authorized_keys:
|
|
- ssh-rsa AAAAB3...
|
|
|
|
bootcmd:
|
|
- echo "VM starting..."
|
|
|
|
runcmd:
|
|
- apt-get update
|
|
- apt-get upgrade -y
|
|
```
|
|
|
|
