離線安裝docker
https://download.docker.com/linux/static/stable/x86_64/ 下載離線包地址
https://download.docker.com/linux/static/stable/aarch64/
https://docs.docker.com/engine/install/binaries/
1 setup
cd /usr/local/resource/docker tar -xvf docker-19.03.4.tgz mv docker/* /usr/bin/ # 將二進制文件移動到bin下
2 systemd docker.service
vim /etc/systemd/system/docker.service
3 然后將以下內容粘貼進去（通用）：
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network-online.target firewalld.service Wants=network-online.target [Service] Type=notify # the default is not to use systemd for cgroups because the delegate issues still # exists and systemd currently does not support the cgroup feature set required # for containers run by docker ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock ExecReload=/bin/kill -s HUP $MAINPID # Having non-zero Limit*s causes performance problems due to accounting overhead # in the kernel.

4 授予執行權限：
chmod +x /etc/systemd/system/docker.service
5 重新加載：
systemctl daemon-reload systemctl start docker systemctl enable docker.service
6 測試是否成功：
systemctl status docker docker -v
rpm方式安裝
rpm -ivh containerd.io-1.2.2-3.el7.x86_64.rpm rpm -ivh container-selinux-2.107-3.el7.noarch.rpm rpm -ivh docker-ce-18.09.8-3.el7.x86_64.rpm rpm -ivh docker-ce-cli-18.09.8-3.el7.x86_64.rpm
7 配置docker 的阿里雲加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://aiyf7r3a.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
# docker info | grep aliyuncs
https://aiyf7r3a.mirror.aliyuncs.com/
8、在線安裝
$ wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo $ yum install docker-ce-19.03.6 docker-ce-cli-19.03.6 -y
