ironic-python-agent CoreOS Image builder.
Builds a CoreOS image suitable for running the ironic-python-agent on a server.
Must be run from a linux machine with a working docker installation and python-pip
Run the following locally or from a virtualenv to install the python requirements
pip install -r requirements.txt
Booting the agent with this image
The image is typically booted via PXE. Here's an example ipxe configuration (replace my-web-server with the IP/hostname of the http server hosting your image):
#!ipxe dhcp kernel http://my-web-server/coreos_production_pxe.vmlinuz initrd http://my-web-server/coreos_production_pxe_image-oem.cpio.gz boot
You can either embed a configuration file into the image, or set configuration options via the kernel command line. The only value most people will need is:
But any config value supported in the agent can be given to the agent via the kernel command line, which allows the use of the same agent image across environments because it contains no state.
Openstack Ironic supports booting IPA via virtual media in the form of an ISO image. Please see Ironic documentation for details on running in this configuration.
Getting the agent
If you don't want to build your own image, you can download a copy of ironic-python-agent ramdisk and kernel, built using CoreOS, at: https://tarballs.openstack.org/ironic-python-agent/coreos/files/coreos_production_pxe-master.vmlinuz and https://tarballs.openstack.org/ironic-python-agent/coreos/files/coreos_production_pxe_image-oem-master.cpio.gz
"master" may be replaced with "stable-$branch" (e.g. "stable-mitaka") to download an image built from the stable/$branch (e.g. stable/mitaka) version of ironic-python-agent.
To create a docker repository and embed it into a CoreOS pxe image:
To just create the docker repository in oem/container.tar.gz:
To embed the oem/ directory into a CoreOS pxe image:
Note: In order to have the ability to ssh into the created image, you need to pass ssh keys in via the kernel command line for CoreOS, or create oem/authorized_keys with the keys you need added before building the image.
To create a CoreOS ISO image to boot with virtual media:
