Sidero 0.3.0-alpha.1 (2021-05-20)

Welcome to the v0.3.0-alpha.1 release of Sidero!
This is a pre-release of Sidero

Please try out the release binaries and report any issues at
https://github.com/talos-systems/sidero/issues.

ServerClass any and Environment default

Sidero now creates ServerClass any which matches all servers.

Environment default is created which will supply Talos release that Sidero was built with, as well as default kernel flags.

Boot from Disk Methods

If the server is configured to PXE boot by default, it might hit the Sidero iPXE server after Talos install, so Sidero has to force the
server to boot from disk.

Sidero 0.2 supports default method via iPXE exit command, but this command doesn't always work
(details).

Sidero 0.3 adds support for two additional methods:

• http-404 force HTTP 404 response from iPXE server
• ipxe-sanboot uses sanboot command to boot from the first disk

Variable SIDERO_CONTROLLER_MANAGER_BOOT_FROM_DISK_METHOD controls this setting.

Install and Upgrade Variables

Some aspects of Sidero installation can now be controlled via environment variables or clusterctl variables.

IPMI Discovery and Automatic Setup

Sidero agent by default discovers BMC (IPMI) endpoint when it first runs on the server and provisions user for Sidero automatically.
This feature enables completely automated server and IPMI discovery on the agent boot.
Variable SIDERO_CONTROLLER_MANAGER_AUTO_BMC_SETUP can be used to disable this feature during install or upgrade of Sidero.

Additionally Sidero supports storing IMPI credentials in Kubernetes secrets referencing them from the Server object.

iPXE script

iPXE image delivered by Sidero (either ipxe.efi or undionly.kpxe) now contains embedded iPXE script to access Sidero iPXE server.
This change allows to simplify DHCP server setup to return only iPXE image without any additional ifs.

Label Selector support in ServerClass

ServerClasses now support Kubernetes label selectors: Servers can be selected based on their labels.

metal-controller-manager External Ports Change

Component metal-metadata-server was merged into metal-controller-manager, and three separate HTTP endpoints were merged into one endpoint on port :8081:

• iPXE server (which used to be on port 8081)
• internal gRPC server (Sidero agent uses it to talk back to Sidero service), previously was 50001
• metadata server endpoint (used to be separate deployment and service, docs used port 9091)

Support for arm64

All components are now capable of running on arm64, including Rasberry Pi 4.

Sidero can provision amd64 and arm64 nodes from any platform.
Only UEFI boot is supported for arm64.

Note: Upstream CAPI includes kube-rbac-proxy component which is not compatible with arm64 at the moment of this writing.
A workaround is to patch the deployment to bump the kube-rbac-proxy image from v0.4.1 to v0.8.0.
