安装Docker

下载Docker安装包:

安装Docker

sudo dpkg -i docker-ce_17.05.0~ce-0~ubuntu-xenial_amd64.deb

安装Compose

sudo curl -fSL http://github.com/docker/compose/releases/download/1.13.0/docker-compose-Linux-x86_64 -o /usr/local/bin/docker-compose

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

docker-ce-17.05-ubuntu-16.04-LTS-install

Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

如果报以上错误，那是因为你的操作系统没有附带libltdl7，可以使用以下命令安装它;

$ sudo apt-get install -y libltdl7
