Ubuntu 20 Docker安裝指令碼

安裝指令碼適用於Ubuntu 20 LTS，指令碼將會安裝Docker，SSH，CURL等軟體，安裝完畢後重啟系統

Docker版本為最新版本，指令碼將自動配置Docker加速源

#! /bin/bash
# 適用於Ubuntu 20

#安裝Vim Git g++ ssh 等服務
sudo apt-get update
sudo apt install vim git g++ ssh python3-pip curl -y

# 安裝Docker
sudo apt-get remove docker docker-engine docker.io containerd runc -y
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release -y

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

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

# 新增docker源加速，並設定容器驅動為kubeadm推薦的systemd
