Ubuntu 16.04 安装 Kubernetes

安装 Docker

apt-get update && apt-get install docker.io

安装 kubelet kubeadm kubectl

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

swapoff -a

sudo sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab

sed -i '0,/ExecStart=/s//Environment="KUBELET_EXTRA_ARGS=--cgroup-driver=cgroupfs"\n&/' /etc/systemd/system/kubelet.service.d/10-kubeadm.conf

指定 kube 版本

上面的方式会安装最新版本，也可以指定版本。

查看 kubernetes 版本：

curl -s https://packages.cloud.google.com/apt/dists/kubernetes-xenial/main/binary-amd64/Packages | grep Version | awk '{print $2}'

安装目标版本：

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - && \
  echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list && \
  sudo apt-get update -q && \
  sudo apt-get install -qy kubelet=<version> kubectl=<version> kubeadm=<version>

示例：

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - && \
  echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list && \
  sudo apt-get update -q && \
  sudo apt-get install -qy kubelet=1.9.6-00 kubectl=1.9.6-00 kubeadm=1.9.6-00

服务自动启动

systemctl start docker && systemctl enable docker

systemctl start kubelet && systemctl enable kubelet
