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.
Project
How To
Prerequisites
- Docker - Cloud / Edge
- Kubeadm/kubectl - Cloud only
- Create cluster with kubeadm - Cloud only
Set up "GO"
$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
Build KubeEdge
$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
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
$GOPATH/src/github.com/kubeedge/kubeedge/build/tools/certgen.sh genCertAndKey edge
The cert/key will be generated in the /etc/kubeedge/ca
and /etc/kubeedge/certs
respectively.
Run Cloud
Certificates:
The path to the generated certificates should be updated in $GOPATH/src/github.com/kubeedge/kubeedge/cloud/edgecontroller/conf/controller.yaml
. Please update the correct paths for the following :
- cloudhub.ca
- cloudhub.cert
- cloudhub.key
cd $GOPATH/src/github.com/kubeedge/kubeedge/cloud/edgecontroller
./edgecontroller
- You need to create a node on k8s master ( Cloud )
kubectl apply -f $GOPATH/src/github.com/kubeedge/kubeedge/build/node.json
Run Edge
Certificates:
$GOPATH/src/github.com/kubeedge/kubeedge/edge/conf/edge.yaml
websocket:URL
controller:node-id
edged:hostname-override
$sudo ./edge_core
Note: need sudo Permission
