Talos 0.14.0-alpha.2 (2021-11-30)

Welcome to the v0.14.0-alpha.2 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.

Kexec and capabilities

When kexec support is disabled
Talos no longer drops Linux capabilities (CAP_SYS_BOOT and CAP_SYS_MODULES) for child processes.
That is helpful for advanced use-cases like Docker-in-Docker.

If you want to permanently disable kexec and capabilities dropping, pass kexec_load_disabled=1 argument to the kernel.

For example:

install:
  extraKernelArgs:
    - sysctl.kernel.kexec_load_disabled=1

Please note that capabilities are dropped before machine configuration is loaded,
so disabling kexec via machine.sysctls will not be enough.

Cluster Discovery

Cluster Discovery is enabled by default for Talos 0.14.
Cluster Discovery can be disabled with talosctl gen config --with-cluster-discovery=false.

Kubelet

Kubelet service can now be restarted with talosctl service kubelet restart.

Kubelet node IP configuration (.machine.kubelet.nodeIP.validSubnets) can now include negative subnet matches (prefixed with !).

Log Shipping

Talos can now ship system logs
to the configured destination using either JSON-over-UDP or JSON-over-TCP:
see .machine.logging machine configuration option.

NTP Sync

Talos NTP sync process was improved to align better with kernel time adjustment periods and to filter out spikes.

SideroLink

A set of Talos ehancements is going to unlock a number of exciting features in the upcoming release of Sidero:

• SideroLink: a point-to-point Wireguard tunnel connecting Talos node back to the provisioning platform (Sidero).
• event sink (kernel arg talos.event.sink=http://10.0.0.1:4000) delivers Talos internal events to the specified destination.
• kmsg log delivery (kernel arg talos.logging.kernel=tcp://10.0.0.1:4001) sends kernel logs as JSON lines over TCP or UDP.

talosctl support

talosctl CLI tool now has a new subcommand called support, that can gather all
cluster information that could help with future debugging in a single run.

Output of the command is a zip archive with all talos service logs, kubernetes pod logs and manifests,
talos resources manifests and so on.
Generated archive does not contain any secret information so it is safe to send it for analysis to a third party.

Component Updates

• Linux: 5.15.5
• etcd: 3.5.1
• containerd: 1.5.8
• Kubernetes: 1.23.0-rc.0
• CoreDNS: 1.8.6

Talos is built with Go 1.17.3

Kubernetes Upgrade Enhancements

talosctl upgrade-k8s now syncs all Talos manifest resources generated from templates.

So there is no need to update CoreDNS, Flannel container manually after running upgrade-k8s anymore.
