vim kube-up.sh

# 使api-server提供跨來源資源共享(CORS)功能

# 在250行加入
--cors-allowed-origins=["http://*"]\

# 設定環境變數,nodes="[master-username]@[master-ip]"用來設定master是誰
export KUBE_VERSION=1.5.0 
export FLANNEL_VERSION=0.5.0 
export ETCD_VERSION=3.0.0 
export nodes="[master-username]@[master-ip]" 
export role="ai" 
export NUM_NODES=${NUM_NODES:-1} 
export SERVICE_CLUSTER_IP_RANGE=192.168.3.0/24 
export FLANNEL_NET=172.16.0.0/16

安裝kubectl指令

# To download a specific version, for example, to download version v1.6.6 on Linux, type:
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.6.6/bin/linux/amd64/kubectl

# Download the latest release with the command:
# curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl

# Make the kubectl binary executable.
chmod +x ./kubectl

# Move the binary in to your PATH.
sudo mv ./kubectl /usr/local/bin/kubectl

ssh-keygen
ssh-add /home/nmsl-master/.ssh/id_rsa

#方法二
$ eval $(ssh-agent)
$ export .....

• curl: (60) SSL certificate problem: unable to get local issuer certificate
