= Introduction =

KubeEdge is an open source system extending native containerized application orchestration and device management to hosts at the Edge. It is built upon Kubernetes and provides core infrastructure support for networking, application deployment and metadata synchronization between cloud and edge. It also supports '''MQTT''' and allows developers to author custom logic and enable resource constrained device communication at the Edge. KubeEdge consists of a cloud part and an edge part.

= How To =

== [https://github.com/kubeedge/kubeedge/blob/master/docs/getting-started/usage.md#run-kubeedge Prerequisites] ==

*Docker - Cloud / Edge
*Kubeadm/kubectl - Cloud only
*Create cluster with kubeadm - Cloud only

== Set up "GO"  ==
<pre>$curl -O https://dl.google.com/go/go1.9.7.linux-amd64.tar.gz
$sudo tar -xvf go1.9.7.linux-amd64.tar.gz
$sudo mv go /usr/local
$sudo vim ~/.profile
PATH="$HOME/bin:$HOME/.local/bin:$PATH:/usr/local/go/bin</pre>

== Build KubeEdge ==
<pre>$mkdir KubeEdge
$export GOPATH=/home/adv/work/KubeEdge
$git clone https://github.com/kubeedge/kubeedge.git $GOPATH/src/github.com/kubeedge/kubeedge
$cd $GOPATH/src/github.com/kubeedge/kubeedge
$make
</pre>

== Configuring MQTT mode ==

#internalMqttMode: internal mqtt broker is enabled.
#bothMqttMode: internal as well as external broker are enabled.
#externalMqttMode: only external broker is enabled.

== Generate Certificates ==
<pre>$GOPATH/src/github.com/kubeedge/kubeedge/build/tools/certgen.sh genCertAndKey edge</pre>

The cert/key will be generated in the <code>/etc/kubeedge/ca</code> and <code>/etc/kubeedge/certs</code> respectively.

== Run Cloud ==

Certificates:

The path to the generated certificates should be updated in <code>$GOPATH/src/github.com/kubeedge/kubeedge/cloud/edgecontroller/conf/controller.yaml</code>. Please update the correct paths for the following :

*cloudhub.ca
*cloudhub.cert
*cloudhub.key
<pre>cd $GOPATH/src/github.com/kubeedge/kubeedge/cloud/edgecontroller</pre>

./edgecontroller

*You need to create a node on k8s master ( Cloud )
<pre>kubectl apply -f $GOPATH/src/github.com/kubeedge/kubeedge/build/node.json</pre>

== Run Edge ==

Certificates:

$GOPATH/src/github.com/kubeedge/kubeedge/edge/conf/edge.yaml

*<code>websocket:URL</code>
*<code>controller:node-id</code>
*<code>edged:hostname-override</code>
<pre>$sudo ./edge_core</pre>
