# Packer Cloud Images
Build your own cloud images from scratch within minutes.
## Features
Most cloud providers provide prebuilt images for different Linux distributions through a marketplace. The quality and usability differs from image to image. Therefore it makes sense to build your own images to provide VMs tailored to your use case. In addition it gives you full control how and when the images are updated.
This repository makes use of Packer to build custom images for a few Linux distributions. These images should fullfil the following requirements:
- Minimal installation
- Support for OpenStack
After building the images upload them to the specific cloud and start spawn VMs from them.
## Requirements
Ensure the following requirements are installed:
- [Packer](https://www.packer.io/)
- QEMU / KVM
## Installation
Follow the steps below to build the images:
```shell
sudo PACKER_LOG=1 /path/to/packer build centos7-lvm-qemu.json
```
Pick any of the available JSON files to build an image for the required distribution.
## Test the image using kvm
Source:
- Install cloud-utils on the host for converting the user-data to a disk image
- Create a copy of the generated image as the root disk of the VM
- Create a cloud-config user data file
```shell
cloud-localds my-seed.img cloud-config.yml
sudo cp my-seed.img /var/lib/libvirt/images/test/my-seed.img
sudo cp images/centos-7-lvm/localhost.localdomain /var/lib/libvirt/images/test/test.qcow2
# resize disk (optional)
sudo qemu-img resize /var/lib/libvirt/images/test/test.qcow2 15G
virt-install \
--memory 2048 \
--vcpus 2 \
--name centos-7-lvm \
--disk /var/lib/libvirt/images/test/test.qcow2,device=disk \
--disk /var/lib/libvirt/images/test/my-seed.img,device=cdrom \
--os-type Linux \
--os-variant centos7.0 \
--virt-type kvm \
--graphics spice \
--network default \
--import
```
## Openstack
Requirements:
-

-
## After resize of root disk
```shell
growpart /dev/vda 2
pvresize /dev/vda2
```
vg has now more free space to allocate
