ubuntu arm环境下安装docker

1.卸载旧版本docker

sudo apt remove docker docker-engine docker-ce docker-io

2.安装依赖使apt可通过HTTPS下载包

sudo apt update && apt install -y apt-tranport-https ca-certificates curl 
software-properties-common

3.添加docker密钥

阿里云：

curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

官方源：

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

4.添加对应的docker源

阿里云:

sudo add-apt-repository "deb [arch=arm64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"

官方源：

sudo add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

5.安装docke

sudo apt update && apt install -y docker-ce

6.配置镜像仓库

mkdir /etc/docker
cat > /etc/docker/daemon.json << EOF
{
    "registry-mirrors": [
        "https://docker.mirrors.ustc.edu.cn/"
    ]
}
EOF
# 设置完成后重启
sudo systemctl daemon-reload
sudo systemctl restart docker
