Kubernetes Version Compatibility

The daemon image contains a 1.22.x k8s.io/{client-go,kubectl} for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.21.x, 1.22.x and 1.23.x

Kured 1.8.2

Minor Release 1.8.2

1.8.1 was only half-released - so here the changelog for all changes since 1.8.0.

No breaking changes, but you might want to double-check and review https://containrrr.dev/shoutrrr/v0.5/services/overview/ though to make sure you got your notify-url (new) or slack-hook-url (old) correct. See #368 for more detail.

Features and Improvements

• Release images to GHCR as well as DockerHub #439
• Support json logformatter

  This commit introduces a new flag '--log-format' that allows a user
  to configure json logging on the pods. If the log-format
  is not specified, the formatter will default to the existing
  text formatter.

Dependency Updates

• Alpine 3.15.0 #467
• dependabot: update docker images too
• various GH Actions
• github.com/prometheus/common 0.32.0 #453
• github.com/containrrr/shoutrrr 0.5.2 #450

Clean Up

• Remove notification/slack package #368

Helm Chart

• add missing prefer-no-schedule-taint
• add rebott-sentinel-command
• correct indent #447
• add reboot-delay
• add alert-firing-only

Kubernetes Version Compatibility

The daemon image contains a 1.21.x k8s.io/{client-go,kubectl} for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.20.x, 1.21.x and 1.22.x

Breaking changes

--annotationTTL was renamed to --lockTTL (Helm chart values accordingly). Unfortunately this feature didn't quite work in the past release (see #213 etc.), so the breaking change is not as bad as it sounds.

Bug fixes

• #213 and #238: Replaced --annotationTTL with --lockTTL and made it work correctly
• #237: Drain: allow pods grace period to terminate
• #166: Remove quote for parameter alert-filter-regexp

Clean Up

• #217: Clean up deps, update docs to explain state post-210
• #210: feature: Remove kubectl bin
• #198: fix: Follow DKL-DI-0004 guideline
• #194: add missing quote - thanks Karan Arora for reporting

Release automation

• #185: Release helper
• #221: Add Lint job in github actions
• #222: Make go lint on pkg folder happier
• #215: Make go lint on cmd folder happier

The daemon image contains a 1.18.x k8s.io/client-go and k8s.io/kubectl for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.1[789].x.

Kured 1.5.0

If you have been upgrading through the 1.4.x releases, 1.5.0 mostly just adds support for newer k8s client tools and updates other internal build components.

Since 1.4.0 we landed quite a few improvements though.

Improvements

• #119: Adding --annotation-ttl for automatic unlock
• #150: Move kured Helm Chart from /helm/charts/stable
• reapply #134: print node id when commanding reboot
