Changelog

  • v0.8.0

    • Upgraded to Kubernetes v1.3.6 and flannel v0.6.1
    • Using official Kubernetes binaries and docker images
    • Most of the code is "official" from kube-deploy/docker-multinode
    • All binaries and images are now cross-compiled from amd64, no more releasing from Raspberry Pis!
    • Using HypriotOS v1.0.1!
    • It's fully possible to add amd64 nodes seamlessly with docker-multinode
    • Made the dns and the dashboard addons mandatory, they can't and shouldn't be disabled as they're required components of the core.
    • The earlier skydns component has been replaced with the new kubedns component that is more integrated with Kubernetes and more efficent.
    • Raspbian is supported out-of-the-box, just download the deb package and install on your Pi!
    • Pine64 is now supported as a platform.
    • Upgraded the addons:
      • dashboard to v1.1.1
      • kubedns to 1.5 (manifest version v17.1)
      • registry to v2.5.0
      • heapster to v1.2.0-beta.2
      • influxdb to v0.13.0
      • grafana to v3.1.1
    • Total refactor of kube-config and of the whole project; as much as possible official Kubernetes code is used, which means the configuration for v0.8.0 is more generic than v0.7.0 which was more specialized.
    • Added the helm package manager at version v2.0.0-alpha.3
    • kube-registry-proxy is now added to the registry addon which makes every node expose the registry at localhost:5000
    • Possible to use --containerized by adding export USE_CONTAINERIZED=true to /etc/kubernetes/k8s.conf
    • Renamed kube-systemd to docker-multinode and the generic systemd OS to the generic debian OS
    • Caveats:
    • Reboots aren't working nor supported. (Added to roadmap)
    • Arch Linux ARM, the Pine64 and Scaleway suffers from the docker pull mtu bug docker/docker#22635

  • v0.7.0 (21th Mar 2016)

    • Upgrade to Kubernetes v1.2.0 Changelog, dashboard v1.0.0, etcd v2.2.5, registry v2.3.1
    • Using official binaries built from my Kubernetes PR: kubernetes/kubernetes#19769
    • Added cluster monitoring! Heapster v1.0.0, influxdb v0.10.3 and grafana v2.6.0
    • Changed to "native" kubelet mode. No more --containerized hack. Makes it possible to use Downward API
    • Switched to host-gw instead of udp as the default flannel backend for improved performance as @larmog suggested. Also made the option FLANNEL_BACKEND in k8s.conf
    • Compile flannel and registry statically. That reduces their total image size 147 MB
    • Deprecated and removed luxas/raspbian in favor for plain resin/rpi-raspbian:jessie
    • Added master.json to the hyperkube image so it's easy to spin up a one-node cluster as docker.md in official docs does.
    • Using @hypriot's prebuilt Go tarballs for luxas/go. Will switch to official go1.6 soon.
    • Added experimental RancherOS to sdcard/write.sh, but no Kubernetes rootfs is available yet
    • Made the storage driver easily changeable with the DOCKER_STORAGE_DRIVER in /etc/kubernetes/k8s.conf
    • Changed indentation to spaces instead of tabs for the most of the files. Also trying to end all files with a newline.
    • Replaced sleep based timeouts in kube-config for condition based loops, makes it faster and more reliable
    • Added a debugging option in kube-config by specifying K8S_DEBUG=1 before the command.
    • Fixed a HypriotOS/.deb-file issue where sudo modified the $PATH so kube-config couldn't find kubectl @DorianGray
    • More reliable SD Card creation by using partprobe @DorianGray
    • Lowered the nodeMonitorGracePeriod and the podEvictionTimeout as @saturnism suggests
    • Changed proxying mode to iptables for better performance.
    • Added a script for cross-compiling Kubernetes to ARM 64-bit on a amd64 host.
    • Other minor enhancements, improvements and bug fixes are included too.

  • v0.6.5 (14th Feb 2016)

    • Add a http loadbalancer. Thanks for the help @larmog
    • Upgrade to and support docker-1.10.0 only
    • Kubernetes Dashboard UI added as an addon
    • Do not depend on pacman, use a self-built statically linked ARMv6 docker-1.10 binary instead
    • Revert to userspace proxying, since iptables proxying had some bugs in it
    • Better documentation
    • A worker may now reboot and come up again in some minutes
    • Better UX when writing the hypriot image, caches the downloaded image for faster writes and installs unzip if not present
    • Bug fixes
    • Rearranged the addon manifests

  • v0.6.3 (9th Jan 2016)
