前提条件

• Kubernetes集群已经部署完毕
• Master节点已经添加node-role.kubernetes.io/master: "" 标签

部署Cloud Controller Manager

配置Kubelet

为Kubelet配置ProviderID (需要为集群中所有节点执行此操作)

META_EP=http://100.100.100.200/latest/meta-data
echo `curl -s $META_EP/region-id`.`curl -s $META_EP/instance-id`
## for example
cn-shanghai.i-ufxxxxxxxxkb6xxo

为Node添加ProviderID

kubectl patch node xxxx -p '{"spec":{"providerID":"cn-shanghai.i-ufxxxxxxxxkb6xxo"}}'

设置AK

1）获取AK信息

2）对AK信息进行base64加密

echo -n "xxxxxxxxxxx" | base64

3）创建ConfigMap

apiVersion: v1
kind: ConfigMap
metadata:
  name: cloud-config
  namespace: kube-system
data:
  cloud-config.conf: |-
    {
        "Global": {
            "accessKeyID": "$Base64AccessKeyID",
            "accessKeySecret": "$Base64AccessKeySecret"
        }
    }

创建cloud-controller-manager.conf （需要在所有Master节点上执行）

将下述文件保存为 /etc/kubernetes/cloud-controller-manager.conf

其中， $CA_DATA 为 cat /etc/kubernetes/pki/ca.crt|base64 -w 0 的执行结果，

server地址为集群的apiserver地址。

kind: Config
contexts:
- context:
    cluster: kubernetes
    user: system:cloud-controller-manager
  name: system:cloud-controller-manager@kubernetes
current-context: system:cloud-controller-manager@kubernetes
users:
- name: system:cloud-controller-manager
  user:
    tokenFile: /var/run/secrets/kubernetes.io/serviceaccount/token
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: $CA_DATA
    server: https://192.168.1.76:6443
  name: kubernetes

创建cloud-controller-manager

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole

等待Pod running

kubectl -nkube-system get po|grep cloud-controller-manager

验证

1）创建deploy

kubectl create deploy nginx --image=nginx

2) 创建LoadBalancer类型svc

kubectl expose deploy nginx --name=test --port=80 --type=LoadBalancer
