Annie Lezil fdcb0922a5 Collect NIC name given by BIOS

Adds an extra field ``biosdevname`` to network interface inventory
collected by ``default`` inspection collector (which collects the whole
inventory returned by hardware manager) of ironic-python-agent.

This feature requires biosdevname utility to collect the bios given NIC
names. The tooling module for tinyIPA is created for the same purpose.
For CoreOS IPA pxe images, biosdevname tooling module is limited,
because Docker repository is created and embedded into CoreOS pxe
images. The Docker repository uses debian to download the packages.
Debian does not have biosdevname package.

Adds an export variable TINYIPA_REQUIRE_BIOSDEVNAME. Set this
variable to ``true`` in your shell before building tinyIPA.

Tiny Core Ironic Python Agent

Build script requirements

For the main build script:

wget
pip
unzip
sudo
awk
mksquashfs

For building an ISO you'll also need:

genisoimage

Instructions:

To create a new ramdisk, run:

make

or:

./build-tinyipa.sh && ./finalise-tinyipa.sh

This will create two new files once completed:

tinyipa.vmlinuz
tinyipa.gz

These are your two files to upload to glance for use with Ironic.

Building an ISO from a previous make run:

Once you've built tinyipa it is possible to pack it into an ISO if required. To create a bootable ISO, run:

make iso

or:

./build-iso.sh

This will create one new file once completed:

tinyipa.iso

To build a fresh ramdisk and build an iso from it:

Run:

make all

To clean up the whole build environment run:

Run:

make clean

For cleaning up just the iso or just the ramdisk build:

make clean_iso

or:

make clean_tinyipa

Advanced options

(De)Optimizing the image

If you want the build script to preinstall everything into the ramdisk, instead of loading some things at runtime (this results in a slightly bigger ramdisk), before running make or build-tinyipa.sh run:

export BUILD_AND_INSTALL_TINYIPA=true

By default, building TinyIPA will compile most of the Python code to optimized *.pyo files, completely remove most of *.py and *.pyc files, and run ironic-python-agent with PYTHONOPTIMIZE=1 to save space on the ramdisk. If instead you want a normal Python experience inside the image, for example for debugging/hacking on IPA in a running ramdisk, before running make or build-tinyipa.sh run:

export PYOPTIMIZE_TINYIPA=false

Enabling SSH access to the ramdisk

If you want to enable SSH access to the image, set ENABLE_SSH variable in your shell before building the tinyipa:

export ENABLE_SSH=true

By default it will use public RSA or DSA keys of the user running the build. To provide other public SSH key, export path to it in your shell before building tinyipa as follows:

export SSH_PUBLIC_KEY=<full-path-to-public-key>

Enabling biosdevname in the ramdisk

If you want to collect BIOS given names of NICs in the inventory, set TINYIPA_REQUIRE_BIOSDEVNAME variable in your shell before building the tinyipa:

export TINYIPA_REQUIRE_BIOSDEVNAME=true
