Question

我目前正在Debian 8.2服务器上测试docker，我正在向有经验的人寻求帮助。

我按照官方文档安装了docker（http://docs.docker.com/installation/debian/），现在我正在尝试使用docker compose（https://docs.docker.com/compose/）。我在官方文档中描述了使用pip安装compose（“pip install -U docker-compose”）

运行“docker-compose”会给我一个帮助屏幕，但是“docker-compose up”不起作用并且给我带来很多错误。

有关如何使其工作的任何想法？我错过了什么吗？一个先决条件可能是？

我正在运行docker 1.8.2并撰写1.4.2

Answer 1

使用curl安装docker compose对我有用：

sudo apt-get install curl
sudo curl -L https://github.com/docker/compose/releases/download/1.4.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Answer 2

我已经手动拉出图像，而不是在运行docker-compose.yml时拉出图像。当我运行docker-compose.yml时，它起作用了。

docker-compose不在Debian 8.2上工作
