kubernetes集群搭建(kubeadm,kubelet)

Installing kubeadm on your hosts

Install and Set Up kubectl
　　

curl -LO https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl　　

　　
chmod +x ./kubectl

To add kubectl autocompletion to your profile, so it is automatically loaded in future shells run:
　　

echo "source <(kubectl completion bash)" >> ~/.bashrc　　

install docker

Installing kubelet and kubeadm
　　You will install these packages on all of your machines:
　　
kubelet: the component that runs on all of the machines in your cluster and does things like starting pods and containers.
　　
kubeadm: the command to bootstrap the cluster.
　　If the machine is running CentOS, run:
　　

cat <<EOF > /etc/yum.repos.d/kubernetes.repo　　
[kubernetes]
　　
name=Kubernetes
　　
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
　　
enabled=1
　　
gpgcheck=1
　　
repo_gpgcheck=1
　　
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
　　https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
　　
EOF
　　
setenforce 0
　　
yum install -y kubelet kubeadm
　　
systemctl enable kubelet && systemctl start kubelet
　　

Initializing your master
　　To initialize the master, pick one of the machines you previously installed kubeadm on, and run:
　　

kubeadm init
