Building or downloading a deploy ramdisk image

Ironic depends on having an image with the ironic-python-agent (IPA) service running on it for controlling and deploying bare metal nodes.

You can download a pre-built version of the deploy ramdisk built with the CoreOS tools at:

Building from source

There are two known methods for creating the deployment image with the IPA service:

CoreOS tools

Clone the ironic-python-agent project:

git clone https://opendev.org/openstack/ironic-python-agent

Install the requirements:

RHEL7/CentOS7:

sudo yum install docker gzip util-linux cpio findutils grep gpg

Fedora:

sudo dnf install docker gzip util-linux cpio findutils grep gpg

Ubuntu 14.04 (trusty) or higher:

sudo apt-get install docker.io gzip uuid-runtime cpio findutils grep gnupg cgroup-lite

SUSE:

sudo zypper install docker gzip util-linux cpio findutils grep gpg2

Change directory to imagebuild/coreos:

cd ironic-python-agent/imagebuild/coreos

Start the docker daemon:

Fedora/RHEL7/CentOS7/SUSE:
```
sudo systemctl start docker
```
Ubuntu:
```
sudo service docker start
```
Create the image:
```
sudo make
```
Or, create an ISO image to boot with virtual media:
```
sudo make iso
```

Note

Once built the deploy ramdisk and kernel will appear inside of a directory called UPLOAD.

disk-image-builder

Follow diskimage-builder installation documentation to install diskimage-builder.
Create the image:
```
disk-image-create ironic-agent fedora -o ironic-deploy
```
The above command creates the deploy ramdisk and kernel named ironic-deploy.vmlinuz and ironic-deploy.initramfs in your current directory.
Or, create an ISO image to boot with virtual media:
```
disk-image-create ironic-agent fedora iso -o ironic-deploy
```
The above command creates the deploy ISO named ironic-deploy.iso in your current directory.
