前言

前面說了Kubernetes的架構，今天就來寫Kubernetes如何安裝。

實驗環境

ubuntu 16.04

安裝Docker

1. Update the apt package index

sudo apt-get update

2. Install packages to allow apt to use a repository over HTTPS

apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

3. Add Docker’s official GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
apt-key fingerprint 0EBFCD88

4. Install Docker CE

apt-get update
apt-get install docker-ce docker-ce-cli containerd.io

5. Check Docker Daemon is activate

service docker status

Install Kubernetes (kubelet, kubeadm, kubectl) on Ubuntu

1. Install packages to allow apt to use a repository over HTTPS

apt-get update && apt-get install -y apt-transport-https curl

2. Add kubernetes repository

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

3. Install kubelet, kubeadm and kubectl

apt-get update
apt-get install -y kubelet kubeadm kubectl

這樣就安裝好 kubelet, kubeadm and kubectl了。
