我正在尝试使用 kubeadm 工具创建一个高可用性集群。我正在尝试安装 kubeadm 安装的先决条件中指定的工具。当我运行 sudo apt-get install -y kubelet kubeadm kubectl 时，我收到如下错误，
Building dependency tree
Reading state information... Done
E: Unable to locate package kubelet
E: Unable to locate package kubeadm
E: Unable to locate package kubectl
我的尝试
我正在按照以下官方文档从 kubernetes.io 准备节点。我指的是以下链接，
https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/install-kubeadm/#before-you-begin
当我按照官方文档中的描述继续执行以下命令时，
sudo apt-get update && sudo apt-get install -y apt-transport-https curl
curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
cat <<EOF | sudo tee /etc/apt/sources.list.d/kubernetes.list deb https://apt.kubernetes.io/ kubernetes-xenial main EOF
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl
更新
当我尝试 Mr.Tummala 的答案时，我收到如下错误，
W: Failed to fetch https://apt.kubernetes.io/dists/kubernetes-xenial/InRelease Could not resolve host: apt.kubernetes.io
W: Some index files failed to download. They have been ignored, or old ones used instead.
但结果如无法找到包裹。
最佳答案
看看下面的步骤是否适合你。
sudo apt-get update && sudo apt-get install -y apt-transport-https curl
echo "deb https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list
sudo apt-get update
sudo apt-get install -y kubelet kubeadm kubectl
sudo apt-mark hold kubelet kubeadm kubectl
