When ote-stack runs, a super administrator will be created. The username and password can be modified by changing parameters `superAdminName` and `superAdminPassword` in file deployments/open-api/open-api.yml.  Note that the initial username and password of admin, only works for the first time when ote-stack starts.

Enable edge autonomy feature in your cluster

1. Deploy EdgeHub

For k8s cluster

• Modify the kubelet-bootstrap.conf file of kubelet, the server field points to the listening address of EdgeHub's edge server, the default is: https://127.0.0.1:8778.And kubelet should add startup parameters: --kube-api-content-type=application/json

• Modify the kube-proxy.conf file of kube-proxy, the server field points to the listening address of EdgeHub's edge server, the default is: https://127.0.0.1:8778. And kube-proxy adds startup parameters: --kube-api-content-type=application/json

• Copy the certificate of k8s apiserver, including three files ca.pem, kube-apiserver.pem, kube-apiserver-key.pem. Rename kube-apiserver.pem to edge-server.pem and rename kube-apiserver-key.pem to edge-server-key.pem

• Copy the kubeconfig file to the working directory, modify the server field of the kubeconfig file to point to the listening address of the EdgeHub load balancer, the default is: https://127.0.0.1:6888.

• Start EdgeHub./ote_edgehub k8s -v 2 --kube-config kubeconfig --init-server ${master_ip}:${master_port}

For k3s cluster

• Set k3s agent startup parameters

  Code Block
  --server=https://127.0.0.1:8778 --kubelet-arg=kube-api-content-type=application/json --kube-proxy-arg=kube-api-content-type=application/json

  
  

• Create the ssl directory under the working directory, and copy the k3s certificate files server-ca.crt, server-ca.key and token to the ssl directory. Rename server-ca.crt to edge-server.pem, and rename server-ca.key to edge-server-key.pem.

• Copy the kubeconfig file to the working directory, modify the server field of the kubeconfig file to point to the listening address of the EdgeHub load balancer, the default is: https://127.0.0.1:6888.

• Start EdgeHub

  Code Block
  ./ote_edgehub k3s -v 2 --kube-config kubeconfig --init-server ${master_ip}:${master_port}

  
  

2.Deploy EdgeController

• First need to create EdgeNode CRD

     kubectl apply -f edgenode-crd.yml

• Run edge-controller on a master node of the k8s or k3s cluster

     ./ote_edgecontroller -v 2 -kubeconfig /root/.kube/config

Add a new cluster to ote-stack for management (option)
