我在ec2实例上安装了docker和docker-compose。我也开始使用docker但是当我尝试使用docker-compose时出现错误：
docker-compose我也尝试过使用sudo的命令，但它不会将DOCKER_HOST识别为命令
我没有设置任何using System;

您需要使用sudo运行实际命令：
sudo docker-compose -p docker -f my-compose.yml up -d
Docker在Linux系统上以root身份运行，因此与运行守护程序的所有交互都需要以root身份运行。您可以以用户身份运行命令，但是您没有与正在运行的系统进行交互！
您可以使用以下命令在Amazon Linux上安装docker-compose：
curl -L https://github.com/docker/compose/releases/download/1.4.0/docker-compose-`uname -s`-`uname -m` | sudo tee /usr/local/bin/docker-compose > /dev/null
sudo chmod +x /usr/local/bin/docker-compose
