Building or downloading a deploy ramdisk image

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

  1. Clone the ironic-python-agent project:

    git clone https://opendev.org/openstack/ironic-python-agent
    
  2. 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
    
  3. Change directory to imagebuild/coreos:

    cd ironic-python-agent/imagebuild/coreos
    
  4. Start the docker daemon:

    Fedora/RHEL7/CentOS7/SUSE:

    sudo systemctl start docker
    

    Ubuntu:

    sudo service docker start
    
  5. Create the image:

    sudo make
    
  6. 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

  1. Follow diskimage-builder installation documentation to install diskimage-builder.

  2. 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.

  3. 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.

Note

Fedora was used as an example for the base operational system. Please check the diskimage-builder documentation for other supported operational systems.
