Packer Image Builder for RHEL Family (RedHat, CentOS, Oracle Linux)

Introduction

This packer templates create vagrant, vmware and kvm images of RedHat 6, CentOS 6 and Oracle Linux 6. The templates support VirtualBox, VmWare and KVM. The kvm images, also run in OpenStack.

The OS versions are:

  • RedHat 6.6
  • Centos 6.6
  • Oracle Linux 6.6

For all operating systems we generate images for

  • Virtual Box (user: packer/packer)
  • VmWare (user: packer/packer)
  • OpenStack

This template only is tested against 64 bit systems.

Requirements

The templates are only tested with packer 0.5.2 and later.

Run conversion process

# Build CentOS virtualbox image
PACKER_LOG=1 packer build -only="centos-6-vbox" packer-centos-6.json

# Build Oracle Linux virtualbox image
PACKER_LOG=1 packer build -only="oel-6-vbox" packer-oel-6.json

Build cloud images for openstack

CentOS

# Build CentOS openstack image and compress qcow2 image before 
# upload (normally from 4.5 GB to less than 500 MB)
packer build -only="centos-6-cloud-kvm" packer-centos-6.json

# Reduce the file size
qemu-img convert -c -f qcow2 -O qcow2 -o cluster_size=2M img_centos_6_openstack/centos6_openstack.qcow2 img_centos_6_openstack/centos6_openstack_compressed.qcow2

# Upload the file to open stack
glance image-create --name "CentOS 6.5" --container-format ovf --disk-format qcow2 --file img_centos_6_openstack/centos6_openstack_compressed.qcow2 --is-public True --progress

Oracle Linux

# Build Oracle Linux openstack image and compress qcow2 image before 
packer build -only="oel-6-cloud-kvm" packer-oel-6.json

# Reduce the file size
qemu-img convert -c -f qcow2 -O qcow2 -o cluster_size=2M img_oel_6_openstack/oel6_openstack.qcow2 img_oel_6_openstack/oel6_openstack_compressed.qcow2

# Upload the file to open stack
glance image-create --name "OEL 6.5" --container-format ovf --disk-format qcow2 --file img_oel_6_openstack/centos6_openstack_compressed.qcow2 --is-public True --progress

RedHat

Before you start with RedHat you need a valid subscription to download the latest iso image. Update the iso_url parameter in rhel6.json accordingly. Additionally you need to modify the file scripts/rhn_reg with your user credentials to recieve yum updates during the packer run.

# Build RedHat openstack image
packer build -only="rhel-6-cloud-kvm" packer-rhel-6.json

# Reduce the file size
qemu-img convert -c -f qcow2 -O qcow2 -o cluster_size=2M rhel6_openstack.qcow2 rhel6_openstack_compressed.qcow2

# Upload the file to open stack
glance image-create --name "RedHat 6.5" --container-format ovf --disk-format qcow2 --file rhel6_openstack_compressed.qcow2 --is-public True --progress
