sudo apt-get update
apt-get install -y gnupg2
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
# step 2: 安装GPG证书

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg | sudo apt-key add -
# Step 3: 写入软件源信息
sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/debian $(lsb_release -cs) stable"
# Step 4: 更新并安装Docker-CE
sudo apt-get -y update
sudo apt-get -y install docker-ce

 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# apt-cache madison docker-ce

 Step 2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.1~ce-0~ubuntu-xenial)
# sudo apt-get -y install docker-ce=[VERSION]

修改docker数据目录

#2020 centos and debian
mkdir -p /data/docker

echo '{"graph": "/data/docker"}' >/etc/docker/daemon.json
# cat /etc/docker/daemon.json 
#{"graph": "/data/docker"}

systemctl restart docker

#验证docker储存位置
docker system info | grep "Root Dir"

修改Docker数据目录位置，包含镜像位置

docker-compose

国外

#如果在内网看下面的手工 或者找个国内的 镜像吧 

sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64"  -o /usr/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

#官方教程  有些机器 path没这个目录  
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

 docker-compose 

国内 和手工

curl -L "https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
#curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

#firefox 直接下载居然很快 
wget https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64

curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-Linux-x86_64“

trouble shooting

docker-compose up 启动容器服务超时错误：ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.

docker-compose up 启动容器服务超时错误：ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.


由于docker-compose up 同时启动的服务过多，超过了请求HTTP限制的60s时间仍未全部成功启动起来，所以出现了超时错误：

    ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
               If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

其中60s是默认的时间。
解决思路：

把 COMPOSE_HTTP_TIMEOUT 的值调大，并转为环境变量即可。

解决步骤：

先进入/etc/profile配置文件，执行命令：

    vi /etc/profile

然后在尾部添加上下面代码：

    export COMPOSE_HTTP_TIMEOUT=500
    export DOCKER_CLIENT_TIMEOUT=500

接着使/etc/profile配置文件生效，执行命令：

    source /etc/profile

最后重新执行命令 docker-compose up 即可。

删除volume 后报错 改一下 目录就好了
