Talos 0.12.0-alpha.0 (2021-08-11)

Welcome to the v0.12.0-alpha.0 release of Talos!
This is a pre-release of Talos

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

Support for Self-hosted Control Plane Dropped

Note: This item only applies to clusters bootstrapped with Talos <= 0.8.

Talos 0.12 completely removes support for self-hosted Kubernetes control plane (bootkube-based).
Talos 0.9 introduced support for Talos-managed control plane and provided migration path to convert self-hosted control plane
to Talos-managed static pods.
Automated and manual conversion process is available in Talos from 0.9.x to 0.11.x.
For clusters bootstrapped with bootkube (Talos <= 0.8), please make sure control plane is converted to Talos-managed before
before upgrading to Talos 0.12.
Current control plane status can be checked with talosctl get bootstrapstatus before performing upgrade to Talos 0.12.

Cluster API v0.3.x

Cluster API v0.3.x (v1alpha3) is not compatible with Kubernetes 1.22 used by default in Talos 0.12.
Talos can be configued to use Kubernetes 1.21 or CAPI v0.4.x components can be used instead.

Sysctl Configuration

Sysctl Kernel Params configuration was completely rewritten to be based on controllers and resources,
which makes it possible to apply .machine.sysctls in immediate mode (without a reboot).
talosctl get kernelparams returns merged list of KSPP, Kubernetes and user defined params along with
the default values overwritten by Talos.

Join Node Type

Node type join was renamed to worker for clarity. The old value is still accepted in the machine configuration but deprecated.
talosctl gen config now generates worker.yaml instead of join.yaml.

Networking

• multiple static addresses can be specified for the interface with new .addresses field (old .cidr field is deprecated now)
• static addresses can be set on interfaces configured with DHCP

Performance

• machined uses less memory and CPU time
• more disk encryption options are exposed via the machine configuration
• disk partitions are now aligned properly with minimum I/O size
• Talos system processes are moved under proper cgroups, resource metrics are now available via the kubelet
• OOM score is set on the system processes making sure they are killed last under memory pressure

Security

• etcd PKI moved to /system/secrets
• kubelet bootstrap CSR auto-signing scoped to kubelet bootstrap tokens only

Component Updates

• Linux: 5.10.52
• Kubernetes: 1.22.0
• containerd: 1.5.5
• runc: 1.0.1
• GRUB: 2.06
• Talos is built with Go 1.16.6
