Tool for building and maintaining VirtualBox VMs described as a code in a single definition file.

Description

Vbkick is a simple bash tool for building and maintaining VirtualBox VMs and Vagrant Base Boxes described as a code in a single definition file (vbmachine.cfg). Vbkick is a replacement for Veewee - you may want to read why. Vbkick works on Linux, FreeBSD, MacOSX and has minimal dependencies.

Getting Started

Install/Uninstall

Note: GNU make is required to install from git, you may need to install gmake on your system.

using git

git clone [email protected]:wilas/vbkick.git
# git checkout stable #default (master) branch is for development, if you prefer use more stable version - choose stable branch
sudo make install
sudo make uninstall

or advance via git

git clone [email protected]:wilas/vbkick.git
# sudo BASH_SHEBANG="/usr/bin/env bash" PL_SHEBANG="/usr/bin/env perl" PREFIX="$HOME/bin" make install
sudo PREFIX="$HOME/bin" make install
sudo PREFIX="$HOME/bin" make uninstall

or using curl

# stable version
curl -Lk https://raw.githubusercontent.com/wilas/vbkick/stable/install.sh | sudo bash
curl -Lk https://raw.githubusercontent.com/wilas/vbkick/stable/install.sh | sudo UNINSTALL=1 bash

# development version
curl -Lk https://raw.githubusercontent.com/wilas/vbkick/master/install.sh | sudo STABLE=0 bash

# custom location
# curl -Lk https://raw.githubusercontent.com/wilas/vbkick/master/install.sh | sudo PREFIX="$HOME/bin" bash
# curl -Lk https://raw.githubusercontent.com/wilas/vbkick/master/install.sh | sudo UNINSTALL=1 PREFIX="$HOME/bin" bash

Create own box definition

• look into templates and choose OS (learn also how to organize own definitions)
• look into examples and customize your box
• read about available options in vbmachine.cfg
• read about VMs validation
• help yourself

How to use

create a new vagrant box

vbkick build newVM
vbkick postinstall newVM
vbkick validate newVM
vbkick export newVM

vagrant box add newVM newVM.box
vagrant box list

update an existing vagrant box

vbkick update existingVM
vbkick validate existingVM
vbkick export existingVM

vagrant box remove existingVM virtualbox
vagrant box add existingVM existingVM.box
vagrant box list

snap hack

vbkick build vm_name                    # creates the new VM - this is usually the slowest part
vbkick shutdown vm_name                 # to create clone VM must be powered off
vbkick clone vm_name                    # creates a clone (gold image) of the VM - for another hacking session
vbkick on vm_name                       # turn on VM
vbkick postinstall vm_name              # extra configuration of the new VM

vbkick snap vm_name fresh-install       # save a work
vbkick ssh vm_name                      # hack
vbkick snap vm_name my-first-hack       # save a work
vbkick ssh vm_name                      # hack
vbkick snap vm_name my-second-hack      # save a work

vbkick shutdown vm_name                 # to restore snapshot VM must be powered off
vbkick resnap vm_name fresh-install     # restore saved work
vbkick on vm_name                       # turn on VM

vbkick play vm_name                     # automate hack
vbkick snap vm_name my-auto-hack        # save a work

vbkick lssnap vm_name                   # list all snapshots

Commands

vbkick

Works in both bash 3 and bash 4 (use POSIX mode). If you have trouble using script, let me know.

$ cd to_directory_with vbmachine.cfg

$ man vbkick or vbkick help

vbkick  <action>     <vm_name>
vbkick  build        VM_NAME        # build the new VM
vbkick  postinstall  VM_NAME        # run postinstall scripts via SSH
vbkick  play         VM_NAME        # run play scripts via SSH
vbkick  validate     VM_NAME        # run validate scripts via SSH
vbkick  update       VM_NAME        # run update scripts via SSH
vbkick  export       VM_NAME        # exports the VM and creates Vagrant base box - VM_NAME.box
vbkick  destroy      VM_NAME        # shut down and deletes the VM
vbkick  ssh          VM_NAME        # connect to the VM via SSH
vbkick  on           VM_NAME        # turn on the VM
vbkick  shutdown     VM_NAME        # shut down the VM
vbkick  clone        VM_NAME        # clone the VM
vbkick  lssnap       VM_NAME        # list all snapshots for a given VM
vbkick  snap         VM_NAME        # take the snapshot
vbkick  resnap       VM_NAME        # restore the snapshot
vbkick  delsnap      VM_NAME        # destroy the snapshot
vbkick  list                        # list all VirtualBox machines with the state
vbkick  version                     # print the version and exit
vbkick  help                        # print help

vbtyper.pm

Helps enter key-strokes into a VirtualBox VMs programmatically from the host. It is a filter - handle input from pipe or file.

Example:

$ echo "Hello VM" | vbtyper.pm VM_NAME
$ echo "<Hello*3> VM" | vbtyper.pm VM_NAME

Example keyboard scancodes:

$ echo "Hello VM" | vbtyper.pm
2a 23 a3 aa 12 92 26 a6 26 a6 18 98 39 b9 2a 2f af aa 2a 32 b2 aa

$ echo "<H*3>" | vbtyper.pm
2a 23 a3 aa 2a 23 a3 aa 2a 23 a3 aa

$ echo "<<Wait>*3>" | vbtyper.pm
wait wait wait

Special keys:

<Wait> - helps control boot flow within vbkick

<what*N> - repeats "what" N times
