Overview

Kamaji allows to run control plane components in pods in the MC rather than dedicating nodes in the WC (doc).

Kamaji world

Those pods are controlled through tenantcontrolplanes.kamaji.clastix.io CRs which are reconciled by the kamaji controller.

1. Docker via GS VPN

If running Kind in a VM accessible via GS VPN (e.g. Neoedge), you must change the docker bridge network or it will set it to 172.18.0.0 which conflicts with our Gridscale VPN endpoint.

Set this in /etc/docker/daemon.json

Testing / Observations

(List of states)

vxav

Bare metal servers have different BMCs with different redfish feature sets.

Metal3 relies on Ironic to integrate with the BMC via Redfish.

We can check that a server is compliant with the Ironic feature set using Redfish-Interop-Validator.

• Install the Redfish-Interop-Validator tool

pip install redfish_interop_validator
