解决办法：
下载目前的最新版： docker-compose-Linux-x86_64
详细：
一、docker-compose安装
方法1：curl方法:
github.com/docker/comp…
curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
#或
curl -L https://github.com/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
#授权
sudo chmod +x /usr/local/bin/docker-compose
#检查安装状态
docker-compose --version
方法2：pip方式
pip install --upgrade pip
yum -y install epel-release
yum -y install python-pip
pip install docker-compose
docker-compose version
注意：如是本地下载文件，需将文件上传到 /usr/local/bin/ 文件夹下，然后将其重命名为docker-compose，修改此文件的权限，增加可执行：chmod +x /usr/local/bin/docker-compose
然后再运行
二、Docker设置通过HTTP代理pull
一、注释掉DNS的配置:(如有配置)
vim /etc/resolv.conf
# Generated by NetworkManager
search apa.gad.schneider-electric.com
nameserver xx.xx.xx.xx
改为：
vim /etc/resolv.conf
# Generated by NetworkManager
#search apa.gad.schneider-electric.com
#nameserver xx.xx.xx.xx
二、 代理配置
mkdir -p /etc/systemd/system/docker.service.d
vi /etc/systemd/system/docker.service.d/http-proxy.conf
具体配置内容
[Service]
Environment="HTTP_PROXY=http://xx.xx.xx.xx:80/"
三、重启docker
systemctl daemon-reload
systemctl restart docker
四、查看配置结果
systemctl show --property=Environment docker
如果出现如下输出则配置成功
Environment=HTTP_PROXY=http://x.xx.xx.xx:80/
