Multiplatform (amd64 and arm) Kubernetes cluster setup

The official guide for setting up Kubernetes using kubeadm works well for clusters of one architecture. But, the main problem that crops up is the kube-proxy image defaults to the architecture of the master node (where kubeadm was run in the first place).

This causes issues when arm nodes join the cluster, as they will try to execute the amd64 version of kube-proxy, and will fail.

It turns out that the pod running kube-proxy is configured using a DaemonSet. With a small edit to the configuration, it's possible to create multiple DaemonSets—one for each architecture.

Steps

Follow the instructions at https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/ for setting up the master node. I've been using Weave Net as the network plugin; it see

A demo python code that ..

1) Connects to an IP cam with RTSP
2) Draws RTP/NAL/H264 packets from the camera
3) Writes them to a file that can be read with any stock video player (say, mplayer, vlc & other ffmpeg based video-players)

Done for educative/demonstrative purposes, not for efficiency..!

Auto WiFi detection or wifi hostpot creation during boot for RPI

Note: These are rough notes and there may be some variance as versions of raspbian get updated but should be pretty reliable as a guide.

This gist provides some instructions and config in order to have your Raspberry PI automatically connect to a roamed network, however if it fails to discover an available network it will set itself up as a wireless access point for you to connect to.
