# KVM Ubuntu Image Builder |
|||
|
|||
This is a Vagrant-based qcow2 image builder to build root images for |
|||
KVM/qemu. |
|||
|
|||
Supports: |
|||
|
|||
* Ubuntu 12.04 precise amd64 |
|||
* Ubuntu 13.10 saucy amd64 |
|||
|
|||
# Assumptions |
|||
|
|||
This will use whatever `~/.ssh/id_rsa.pub` is found on the host build system |
|||
as the `/root/.ssh/authorized_keys` inside the image being built. |
|||
|
|||
The root password is set to 'root', but ssh password logins are disabled, so |
|||
it only works at the console. |
|||
|
|||
The mirror in the image is set to `http://mirror.localservice/ubuntu`. It |
|||
is expected that the VM environment you are using will make this resolve |
|||
appropriately and point at a local reverse proxy or full mirror. |
|||
|
|||
# Requires |
|||
|
|||
## Common |
|||
|
|||
* curl |
|||
* jq |
|||
|
|||
## OSX |
|||
|
|||
* Vagrant |
|||
|
|||
## Linux |
|||
|
|||
* root |
|||
* kpartx |
|||
* debootstrap |
|||
* lvm2 |
|||
* qemu-utils |
|||
|
|||
# todo |
|||
|
|||
* support 12.04 (precise) or 12.10 (quantal) (chef server!) |
|||
* refactor local modifications/packages out of base build |
|||
|
|||
# local changes todo |
|||
|
|||
* remove whoopsie |
|||
* remove libwhoopsie0 |
|||
* remove popcon / popularity-contest |
|||
* remove landscape stuff |
|||
* switch ssh to systemd invoked service |
