Hi,

The OS which we want to mirror the randisk for is not supported by ironic-python-agent-builder and diskimage-builder.（It references Fedora and CentOS a lot for the rpm packages building. So somewhat it can be treated as a redhat family distro）

So we need to compare the workload of manual production or adding new OS support for ironic-python-agent-builder. We are new to this field, is there any recommended reference for making manual ramdisk（possible interim measures） or adding os support for ironic-python-agent-builder（Definitely a better solution in the long run）

Appreciate any kind of guidance or help.

Han

Hey,

I strongly suggest using ironic-python-agent-builder to create your ramdisks and then mirror them separately. Customizing the image comes with several benefits:

• Ability to customize cleaning of bespoke hardware using hardware managers + custom tooling https://docs.openstack.org/ironic-python-agent/latest/contributor/hardware_m...
• Ability to choose the distribution you use (note: we only test a couple in CI)
• Ability to add in extra pieces specific to your environment, such as credentials. I've even been in a case where I needed to inject an iptables configuration in order to receive security approval for a deployment.

There is a giant downside to building your own images: the images in the linked locations in tarballs.opendev.org are only published when those specific commits were passing CI. This gives you a stronger behavior guarantee than you get when you build your own.

As for mirroring; our opendev partners may have anintegration they might offer but frankly, if I were doing it myself, I'd probably use a tool such as httrack to sync the files down periodically.

Good luck, let me know if you have any additional questions.

Hi

The.kernel and.initramfs images contained in ramdisk are used to use bare metal services. The open source address provides centos ramdisk mirroring. https://tarballs.opendev.org/openstack/ironic-python-agent/dib/files/ https://tarballs.opendev.org/openstack/ironic-python-agent-builder/dib/files...

I want to build our own ramdisk mirror, and I would like to ask whether there is a way to manually make ramdisk mirror. If so, how to add the ironic python agent service to it? Or use the ironic-python-agent-builder tool to support other system construction methods. ________________________________ 发自我的企业微信

If you're using a redhat-like distribution, you can likely use the existing redhat distro support element to try and make it work for your similar distribution.

There are a couple of other Red Hat derivatives implemented in diskimage-builder already: OpenEuler and Rocky Linux. Those may also provide inspiration.
