v1.25.0 Alpha 5

Changes

Additions

• The system socket now supports restarting cri-o as well as kubelet
• Added a eudev image for distributions which require "nice" things in the host's /dev (for example, some CSI plugins expect /dev/disk/by-id to exist)

Removals

• The magic early boot kubelet reload when the config.yaml file appears on disk is no longer supported. Bootstrap containers should restart the kubelet explictly via the system socket.

Fixes

• /var/lib/kubelet is now a shared mount, so that plugins can see mounts from within their pods

v1.25.0 Alpha 4

Changes

Additions

• seccomp profiles can stored in /etc/seccomp - kubelet is configured to read these
• Documentation now available at https://kios.redcoat.dev
• Most binaries are now built with -flto, making them slightly smaller / more optimised for runtime
• Kubelet will no longer restart static pods when the node name changes
• Kubelet and Crio now log to a named fifo pipe - which is expected to be read by a container, allowing for viewing logs via kubectl logs

Removals

• The /run/system directory used to be created at boot time for some legacy behaviour. This has been removed

Fixes

• Full rebuilds are easier, as build-pkg better cleans each package when called with the --clean flag or CLEAN=1 environment variable
• The build process missed the /dev directory - meaning builds from scratch were failing
• Fixed a race condition which could leave the system unbootable if the container runtime started before lo had been brought up

v1.25.0 Alpha 3

Changes

Additions

• Added a modprobe container, to be used at early bootup to load required kernel modules.
• Added a /etc/kubernetes/node-labels file, which will be passed to kubelet and used during node registration with the api-server
• kiOS init now logs to syslog rather than directly to console (it also logs slightly more)
• kiOS will now rewrite its args for vanity ps output
• We have a policy on the version of kubelet to be supported during alpha.
• kiOS can now autodiscover the data partition meaning the hard requirement on a datapart kernel parameter has been removed (and the build system has been updated to create auto-discoverable partitions) (#1) Thanks @sftim! 🎉
• It is now possible to request a restart of kubelet via the system socket.
• Documentation

Changes

• More unneeded bits of the kernel have been removed or moved to modules
• Node Graceful shutdown has been fixed and will be triggered when either a SIGTERM is sent to init, or \x01 is sent on the system socket.
• Crun is now v1.8.5
• Crio is now v1.26.3
• Kubelet is now v1.25.10
• Linux kernel is now v.6.3.2
• Fixes to the build system
• KubeletConfiguration (config.yaml) is now in /etc/kubernetes rather than /var/lib/kubelet.

Removals

• The bootstrap image has been removed. This was an annoying kubeadm + custom c which was originally written for the raspberry pi and is no longer used / useful.
