Installing KubeEdge with Binary

Deploying KubeEdge with binary is used to test, never use this way in production environment.

Limitation​

  • Need super user rights (or root rights) to run.

Setup Cloud Side (KubeEdge Master Node)​

Create CRDs​

kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/devices/devices_v1beta1_device.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/devices/devices_v1beta1_devicemodel.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/reliablesyncs/cluster_objectsync_v1alpha1.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/reliablesyncs/objectsync_v1alpha1.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/router/router_v1_ruleEndpoint.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/router/router_v1_rule.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/apps/apps_v1alpha1_edgeapplication.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/apps/apps_v1alpha1_nodegroup.yaml
kubectl apply -f https://raw.githubusercontent.com/kubeedge/kubeedge/master/build/crds/operations/operations_v1alpha1_nodeupgradejob.yaml

Prepare cloudcore binary​

There're two ways to download cloudcore binary.

  • Download from github release.

    Now KubeEdge github officially holds three arch releases: amd64, arm, arm64. Please download the right package according to your platform.

    wget https://github.com/kubeedge/kubeedge/releases/download/v1.12.0/kubeedge-v1.12.0-linux-amd64.tar.gz
    tar -zxvf kubeedge-v1.12.0-linux-amd64.tar.gz
    cp kubeedge-v1.12.0-linux-amd64/cloud/cloudcore/cloudcore /usr/local/bin/cloudcore

  • Build from source

    ref: build from source

Prepare config file​

cloudcore --defaultconfig > cloudcore.yaml

please refer to configuration for cloud for details.

Run​

# cloudcore --config cloudcore.yaml

Run cloudcore -h to get help info and add options if needed.

Setup Edge Side (KubeEdge Worker Node)​

Prepare edgecore binary​

There're three ways to download a edgecore binary.

  • Download from github release.

    Now KubeEdge github officially holds three arch releases: amd64, arm, arm64. Please download the right arch package according to your platform.

    wget https://github.com/kubeedge/kubeedge/releases/download/v1.12.0/kubeedge-v1.12.0-linux-amd64.tar.gz
    tar -zxvf kubeedge-v1.12.0-linux-amd64.tar.gz
    cp kubeedge-v1.12.0-linux-amd64/edge/edgecore /usr/local/bin/edgecore

  • Download from dockerhub KubeEdge official release image.

docker run --rm kubeedge/installation-package:v1.12.0 cat /usr/local/bin/edgecore > /usr/local/bin/edgecore && chmod +x /usr/local/bin/edgecore

Prepare config file​

  • generate config file
edgecore --defaultconfig > edgecore.yaml
  • get token value at cloud side:
kubectl get secret -nkubeedge tokensecret -o=jsonpath='{.data.tokendata}' | base64 -d
  • update token value in edgecore config file:
# sed -i -e "s|token: .*|token: ${token}|g" edgecore.yaml

The token is what above step get.

please refer to configuration for edge for details.

Run​

If you want to run cloudcore and edgecore at the same host, run following command first:

export CHECK_EDGECORE_ENVIRONMENT="false"

Start edgecore:

edgecore --config edgecore.yaml

Run edgecore -h to get help info and add options if needed.

Build from source​

If you want to build KubeEdge from source, there are two options:

You have a working Go environment, and would like to build on host directly.

git clone https://github.com/kubeedge/kubeedge.git
cd kubeedge
make BUILD_WITH_CONTAINER=false

You have a working Docker environment, and enjoy building inside container for simplified environment consistency.

git clone https://github.com/kubeedge/kubeedge.git
cd kubeedge
make

The compiled kubeedge binaries will be put to _output/local/bin directory.

Deploy demo on edge nodes​

After you start both cloudcore and edgecore successfully, you can run kubectl get node to ensure whether edgecore has already registered to cloudcore successfully. The edge nodes are in Ready status like below.

# kubectl get node
NAME                 STATUS   ROLES                  AGE     VERSION
ecs-8f95             Ready    agent,edge             5m45s   v1.22.6-kubeedge-v1.12.0
kind-control-plane   Ready    control-plane,master   13m     v1.23.4

Now we can deploy a Pod to edge node, just run the following command:

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
  - name: nginx
    image: nginx:1.14.2
    ports:
    - containerPort: 80
  nodeSelector:
    "node-role.kubernetes.io/edge": ""
EOF

Then you can see the Pod is deployed to edge-node succesfully.

# kubectl get pod -owide
NAME    READY   STATUS    RESTARTS   AGE   IP           NODE       NOMINATED NODE   READINESS GATES
nginx   1/1     Running   0          11s   172.17.0.2   ecs-8f95   <none>           <none>

Congratulations, a KubeEdge cluster is running successfully.
