安装kubeadm，kubelet，kubectl

1.不同环境下的安装，但必须解决科学上网问题

• Ubuntu, Debian or HypriotOS sh : apt-get update && apt-get install -y apt-transport-https curl curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add - cat <<EOF >/etc/apt/sources.list.d/kubernetes.list deb https://apt.kubernetes.io/ kubernetes-xenial main EOF apt-get update apt-get install -y kubelet kubeadm kubectl apt-mark hold kubelet kubeadm kubectl

• CentOS, RHEL or Fedora sh : `cat < /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 exclude=kube* EOF # Set SELinux in permissive mode (effectively disabling it) setenforce 0 sed -i 's/^SELINUX=enforcing$/SELINUX=permissive/' /etc/selinux/config

  yum install -y kubelet kubeadm kubectl --disableexcludes=kubernetes

  systemctl enable kubelet && systemctl start kubelet`

• Container Linux sh : `RELEASE="$(curl -sSL https://dl.k8s.io/release/stable.txt)" mkdir -p /opt/bin cd /opt/bin

  curl -L --remote-name-all https://storage.googleapis.com/kubernetes-release/release/${RELEASE}/bin/linux/amd64/{kubeadm,kubelet,kubectl} chmod +x {kubeadm,kubelet,kubectl}

  curl -sSL "https://raw.githubusercontent.com/kubernetes/kubernetes/\${RELEASE}/build/debs/kubelet.service" | sed "s:/usr/bin:/opt/bin:g" > /etc/systemd/system/kubelet.service mkdir -p /etc/systemd/system/kubelet.service.d curl -sSL "https://raw.githubusercontent.com/kubernetes/kubernetes/\${RELEASE}/build/debs/10-kubeadm.conf" | sed "s:/usr/bin:/opt/bin:g" > /etc/systemd/system/kubelet.service.d/10-kubeadm.conf`

2. 启动kebelet systemctl enable kubelet && systemctl start kubelet
