|
|
## Disaster Recovery
|
|
|
|
Talos now supports `etcd` [snapshots and recovery](../../guides/disaster-recovery/) from the snapshotted state.
|
|
Periodic snapshots of `etcd` data can be taken with `talosctl etcd snapshot` command, and in case of catastrophic control plane
|
|
failure `etcd` contents can be recovered from the latest snapshot with `talosctl bootstrap --recover-from=` command.
|
|
|
|
## Time Synchronization
|
|
|
|
The `timed` service was replaced with a new time sync controller without any machine configuration changes.
|
|
There should be no user-visible changes in the way new time synchronization process works, logs are now
|
|
available via `talosctl logs controller-runtime`.
|
|
Talos now prefers last successful time server (by IP address) on each sync attempt, which improves sync accuracy.
|
|
|
|
## Single Board Computers
|
|
|
|
Talos added support for the [Radxa Rock PI 4c](../../single-board-computers/rockpi_4/) board.
|
|
`u-boot` version was updated to fix the boot and USB issues on Raspberry Pi 4 8GiB version.
|
|
|
|
## Optimizations
|
|
|
|
Multiple optimizations were applied to reduce Talos `initramfs` size and memory footprint.
|
|
As a result, we see a reduction of memory usage of around 100 MiB for the core Talos components which leaves more resources available for you workloads.
|
|
|
|
## Install Disk Selector
|
|
|
|
Install section of the machine config now has `diskSelector` [field](../../reference/configuration/#installconfig) that allows querying install disk using the list of qualifiers:
|
|
|
|
```yaml
|
|
...
|
|
install:
|
|
diskSelector:
|
|
size: >= 500GB
|
|
model: WDC*
|
|
...
|
|
```
|
|
|
|
`talosctl -n <IP> disks -i` can be used to check allowed disk qualifiers when the node is running in the maintenance mode.
|
|
|
|
## Inline Kubernetes Manifests
|
|
|
|
Kubernetes manifests can now be submitted in the machine configuration using the `cluster.inlineManifests` [field](../../reference/configuration/#clusterconfig),
|
|
which works same way as `cluster.extraManifests` field, but manifest contents are passed inline in the machine configuration.
|
|
|
