Development
|
|
===========
|
|
|
|
The cluster isn't going to arrive until at least September. In the
|
|
meantime, there are a few phases of development. This is a rough
|
|
outline of how I think development will progress. The development
|
|
stages will move forward based on when hardware arrives as well as
|
|
when certain acceptance criteria are met.
|
|
|
|
Hardware states
|
|
---------------
|
|
|
|
Key:
|
|
|
|
- Pi 4/X: Pi 4 with X GB of memory
|
|
- CM4 X: Pi CM4 with X GB of memory (has eMMC, wifi, and bluetooth)
|
|
- CM4 XL: Pi CM4 with X GB of memory, lite version (no eMMC, wifi, or
|
|
bluetooth)
|
|
- D35: Zymbit `D35 Secure Edge Node <https://store.zymbit.com/products/secure-compute-node-d35>`_

| image validation | Pi 3B+, CM4 8L |
|

| pxeboot validation | Pi 4/8, CM4 8L |
|

Current stage: 0
|
|
|
|
Stage 0: basic image validation
|
|
-------------------------------
|
|
|
|
Status: basic validation complete.
|
|
|
|
This stage is basic validation that the :doc:`packer` process produces
|
|
valid images. The goal is to get to a place where, with wired
|
|
connectivity, the serial console isn't needed.
|
|
|
|
This is being done on a CM4 8 at the moment with a carrier board.
|
|
|
|
Goals
|
|
^^^^^
|
|
|
|
- Ensure :doc:`packer` produces valid images.
|
|
- Ensure that images can be flash and installed without requiring
|
|
serial console intervention.
|
|
|
|
Stage: PXEboot
|
|
--------------
|
|
|
|
The focus here will be on developing a PXE image and figuring out how
|
|
to get the Pi to boot that. This is mostly to determine whether or not
|
|
this approach will work.
|
|
|
|
Goals
|
|
^^^^^
|
|
|
|
- Determine if PXE boot is a valid approach.
|
|
- Automated build of a PXE image that can perform node
|
|
:doc:`node-provisioning`.
|
|
|
|
Stage: Automated TPM provisioning
|
|
---------------------------------
|
|
|
|
Here, the goal is to have each node automatically provision and
|
|
register its TPM on first boot.
|
|
|
|
Goals
|
|
^^^^^
|
|
|
|
- Build out a TPM provisioning service.
|
|
- Package a TPM provisioner into the boot image.
|
|
|
|
|
|
Stage: 5-node cluster
|
|
-----------------------
|
|
|
|
The next stage is to build out a cluster of 5 Raspberry Pi 4's to
|
|
develop basic node bring up and ansible configuration. This will be
|
|
built on an UCTRONICS `U6260
|
|
<https://www.uctronics.com/uctronics-upgraded-complete-enclosure-for-raspberry-pi-cluster.html>`_
|
|
cabinet.
|
|
|
|
Goals
|
|
^^^^^
|
|
|
|
The 5-node cluster will focus on bringing up nodes automatically.
|
|
|
|
Stage: 6-node cluster
|
|
-----------------------
|
|
|
|
This stage will add a Zymbit D35 secure edge node in as the secure
|
|
root of trust for the cluster - an HSM and identity management system.
