Install KubeEdge

Please refer to this site https://docs.kubeedge.io/en/docs/setup/keadm/.

Setup Cloud Side(Master Node)

Prepare Kubernetes for cloud side

Install Kubernetes in a lower version because the latest version causes errors. I installed with 1.20.12.00 version.

• Install using native package management(Debian-based distributions)

sudo apt-get install -y apt-transport-https ca-certificates curl 

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg 

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list 

• Update apt package index, install kubelet, kubeadm and kubectl, and pin their version

Install Kubernetes in a lower version because the latest version causes errors. I installed with 1.20.12.00 version.

sudo apt-get update

apt install -y kubectl=1.20.12-00 kubelet=1.20.12-00 kubeadm=1.20.12-00 

sudo apt-mark hold kubelet kubeadm kubectl 

• Creating a cluster with kubeadm

sudo kubeadm init --apiserver-advertise-address=<IP ADRESS> --pod-network-cidr=10.244.0.0/16 --upload-certs 

• Installing a Pod network add-on

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/2140ac876ef134e0ed5af15c65e414cf26827915/Documentation/kube-flannel.yml 

Deploying KubeEdge using Keadm

• Create Firewall Rules

By default ports 10000 and 10002 in your cloudcore needs to be accessible for your edge nodes.

iptables -I INPUT -p tcp --dport 10000 -j ACCEPT

iptables -I INPUT -p tcp --dport 10002 -j ACCEPT

iptables -L -v 

• Install keadm

wget https://github.com/kubeedge/kubeedge/releases/download/v1.8.2/keadm-v1.8.2-linux-amd64.tar.gztar -zxvf keadm-v1.8.2-linux-amd64.tar.gzcd keadm-v1.8.2-linux-amd64/keadm 

• Install cloudcore

./keadm init --advertise-address=<THE-EXPOSED-IP>

cat /var/log/kubeedge/cloudcore.log 

Setup Edge Side (KubeEdge Worker Node)

• IP Forward Setting for EdgeMesh

vi /etc/nsswitch.conf 

sudo echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf 

sysctl -p 

• Get Token From Cloud Side

Run keadm gettoken in cloud side will return the token, which will be used when joining edge nodes.

keadm gettoken

• Join Edge Node

keadm join will install edgecore and mqtt. It also provides a flag by which a specific version can be set.

./keadm join --cloudcore-ipport=<THE-EXPOSED-IP>:10000 --token=<TOKEN> 

journalctl -u edgecore.service -b 

Deploying Metrics-server

Enable kubectl logs Feature

Before metrics-server deployed, kubectl logs feature must be activated

• Generate the certificates for CloudStream on cloud node

git clone https://github.com/kubeedge/kubeedge.gitcd kubeedge/build/tools/ 

cp certgen.sh /etc/kubeedge/ 

/etc/kubeedge/certgen.sh stream 

kubectl get cm tunnelport -nkubeedge -oyamliptables -t nat -A OUTPUT -p tcp --dport 10351 -j DNAT --to 192.168.15.67:10003

vi /etc/kubeedge/config/cloudcore.yaml

pkill cloudcore

nohup cloudcore > cloudcore.log 2>&1 &

wget https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.4.0/components

vi components

kubectl taint nodes --all node-role.kubernetes.io/master-

kubectl apply -f components

Keadm 설치는 ./keadm 어쩌구

메트릭 서버는 파스타 대로 해도 됨

vi /etc/kubeedge/config/edgecore.yaml

systemctl restart edgecore.service
