Kubernetes Version Compatibility

The daemon image contains a 1.20.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 1.19.x, 1.20.x and 1.21.x

Thanks a lot to everyone who contributed to kured since 1.6.1. Commits from @cnmcavoy, @ckotzbauer, @evrardjp, @dholbach, @atighineanu, @spingel, @papanito, @t3mi, @jackfrancis.

This is a follow-up release to 1.6.0, bringing in https://github.com/weaveworks/kured/pull/291 to fix the release automation.

From a user perspective, this release will mostly bring you up to date with Kubernetes 1.[18,19,20].x. Behind the scenes Jean-Philippe Evrard (SUSE) put a lot of effort into automated testing, which will give us more confidence in the code we merge.

Kubernetes Version Compatibility

The daemon image contains a 1.18.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 1.1{18,19,20}.x.

Thanks a lot to everyone who contributed to kured since 1.5.1. Commits from @DaniJG, dependabot[bot], @dholbach, @evrardjp, @jack-education, @morancj.

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

Kubernetes Version Compatibility

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.

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

Updates

• Many improvements and modernisation for chart and documentation
• #139: Update to work for match k8s 1.1[789].x

Thanks a lot to @audunsolemdal, @bboreham, @ckotzbauer, @davidkarlsen, @dholbach, @evrardjp and @michalschott who contributed to this release.

This release is part of the 1.4.x series and adds

• Chart: Support extraEnvVars
• documentation updates

Thanks a lot to @audunsolemdal, @ckotzbauer and @dholbach who contributed to this release.

Thanks @davidkarlsen and @ckotzbauer for figuring out issues with the Helm chart.

We are just about to resolve #140 and thus be able to deprecate the charts in /helm/charts this way.

Another release to help us get https://github.com/weaveworks/kured/issues/140 resolved.

Thanks @ckotzbauer.

This is a brown paper-bag release for 1.4.1, adding no new functionality - hopefully this time just getting the Chart deployment right.

Thanks @ckotzbauer for figuring this out with me.

This release adds to the previous 1.4.0 release.

Expect a 1.5.0 release some time after k8s 1.19.0 gets out.

Features

• Adding --annotation-ttl for automatic unlock #119

kured Helm chart

We intend to take over the kured chart from helm/charts/stable. Please consult https://github.com/weaveworks/kured/tree/master/charts/kured for upgrading from the previous chart.

• make sure Circle CI ignores the 'gh-pages' branch #149
• Initial Kured Helm-Chart #150

Thanks a lot everyone who helped with this release, in particular @bboreham, @ckotzbauer, @dholbach, @michalschott and others who helped with testing!

Kubernetes Version Compatibility

As 1.4.0 did, the daemon image contains a 1.17.x k8s.io/client-go and kubectl binary 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[678].x.

Tested in minikube on 1.16.12, 1.17.8, 1.18.5.

This release adds support for newer k8s client tools and updates other internal build components.

Improvements

• Update Alpine base image (#114)
• We're in the #kured channel on Slack (#118)
• We're having monthly meetings (#126)
• Updated kubectl, client-go, etc to k8s 1.17 (#127, #135)
• Update to go 1.13 (#130)
• Unpin specific Alpine image (#131)
• print node id when commanding reboot (#134)
• Update compatbility matrix (#133)
• Check links as part of CI (#138)

Thanks a lot everyone who helped with this release, in particular @crgarcia12, @dholbach, @evrardjp, @pgroene and others who helped with testing!

Kubernetes Version Compatibility

The daemon image contains a 1.15.x k8s.io/client-go and kubectl binary 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 1.15.x and 1.17.x.

Tested in minikube on 1.15.10, 1.16.7 and 1.17.3.

Improvements

• Support for blocking reboot of individual nodes based on the presence of pods with specific labels

Kubernetes Version Compatibility

The daemon image contains a 1.13.x k8s.io/client-go and kubectl binary 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 1.12.x and 1.14.x.

Tested in minikube on 1.12.8, 1.13.6 & 1.14.1.

Improvements

• RBAC support
• Use the systemctl in the host mount namespace to effect reboots, reducing image size and eliminating the potential for incompatibility
• Notify Slack on drain in addition to reboot
• Pass through log output from invoked kubectl commands
• Tolerate NoSchedule taint on node-role.kubernetes.io/master
• Fixed reversal of daemonset name/namespace arguments and comments in the manifest

Kubernetes Version Compatibility

The daemon image contains a 1.12.x k8s.io/client-go and kubectl binary 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 1.11.x and 1.13.x.

Tested in minikube on 1.11.4, 1.12.1 & 1.13.0-alpha.2.
Tested in production on 1.11.2 & 1.12.2.

Kubernetes Version Compatibility

The daemon image contains a 1.7.x k8s.io/client-go and kubectl binary for the purposes of maintaining the lock and draining worker nodes. Whilst it has only been tested on a 1.7.x cluster, Kubernetes typically has good forwards/backwards compatibility so there is a reasonable chance it will work on adjacent versions; please file an issue if this is not the case.
