From @luxas on October 26, 2016 17:31 Did you use Hypriot v1.0.1 as stated in docs? |
|
From @nlamirault on October 26, 2016 18:39 @luxas I've got the same issue with Hypriot 1.0.0. Where i can download the 1.0.1 image ? |

From @derailed on October 26, 2016 19:25 Thanks for pointing this out @luxas! This was indeed a pilot error. Did get further so we can close this issue. Tho the master is now coming up, setting up the pod network using flannel per the docs results in an error.
Yields Error from server: error when creating "flannel.yml": DaemonSet in version "v1beta1" cannot be handled as a DaemonSet: [pos 1115]: json: expect char '"' but got char 'n' Think the node selector config in the flannel config is incorrect nodeSelector: |
|
From @derailed on October 26, 2016 19:31 Probably a bug in the template, me think the nodeSelector should be: nodeSelector: |

From @luxas on October 26, 2016 19:34 Ok, seems like the ARCH=arm thing is working poorly then. Try just running curl -sSL https://raw.githubusercontent.com/luxas/flannel/update-daemonset/Documentation/kube-flannel.yml | sed "s/amd64/arm/g" | kubectl create -f - |

From @derailed on October 26, 2016 21:26 Thank you all for the prompt support! |

Kubernetes master initialised successfully!
You can now join any number of machines by running the following on each node:
kubeadm join --token 482d60.042c2504ce81cd32 192.168.1.23But kubectl fails : The etcd container logs : https://gist.github.com/nlamirault/d84e77e02276d158493f15f249324ba5 |

From @nlamirault on October 27, 2016 12:14 i try the unstable version of kubeadm with reset command. Then i try another init. Etcd container is up, but i've got logs : |

Is this a BUG REPORT or FEATURE REQUEST? (choose one):
Bug
Kubernetes version (use
kubectl version):Environment:
Raspberry Pi 3
HypriotOS v 1.0
uname -a):Linux m10 4.4.15-hypriotos-v7+ #1 SMP PREEMPT Mon Jul 25 08:46:52 UTC 2016 armv7l GNU/Linux
What happened:
Following kubeadm installation docs. I've installed the prereqs and proceeded with the init as follows:
kubeadm init --use-kubernetes-version v1.4.1 --pod-network-cidr=10.244.0.0/16
The command is stuck on:
Looking at docker on this node expecting to see images being installed for etcd, api-server, etc..
but docker images reports nothing. Guessing kubeadm is somehow no able to connect with local docker daemon? or the default Hypriot docker configuration is not jiving with kubeadm??
What you expected to happen:
kubeadm init to complete successfully
How to reproduce it (as minimally and precisely as possible):
o Download Hypriot v1.0 image and flash on SD card
o Boot rp with SD card
o curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
o cat < /etc/apt/sources.list.d/kubernetes.list
deb http://apt.kubernetes.io/ kubernetes-xenial main
EOF
o apt-get update
o apt-get install -y kubelet kubeadm kubectl kubernetes-cni
o kubeadm init --use-kubernetes-version v1.4.1 --pod-network-cidr=10.244.0.0/16
Anything else do we need to know:
Looking at /etc/kubernetes/manifests shows:
etcd.json kube-apiserver.json kube-controller-manager.json kube-scheduler.json
Inspecting journalctl on kubelet shows:
