因为 CoreOS 中 /usr/local/ 不可写，安装在该目录中会提示失败。

但是 /opt/bin 目录可写，同时也在 path 路径下，那我们就可以这样安装。

xx~ # mkdir /opt/xx~ # mkdir /opt/binxx~ # curl -L https://github.com/docker/compose/releases/download/1.3.3/docker-compose-`uname -s`-`uname -m` > /opt/bin/docker-compose  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current                                 Dload  Upload   Total   Spent    Left  Speed100   403    0   403    0     0   1076      0 --:--:-- --:--:-- --:--:--  1080100 7990k  100 7990k    0     0  2137k      0  0:00:03  0:00:03 --:--:-- 3176kxx~ # chmod +x /opt/bin/docker-composexx~ # docker-composeDefine and run multi-container applications with Docker.Usage:  docker-compose [options] [COMMAND] [ARGS...]  docker-compose -h|--helpOptions:  -f, --file FILE           Specify an alternate compose file (default: docker-compose.yml)  -p, --project-name NAME   Specify an alternate project name (default: directory name)  --verbose                 Show more output  -v, --version             Print version and exitCommands:  build              Build or rebuild services  help               Get help on a command  kill               Kill containers  logs               View output from containers  port               Print the public port for a port binding  ps                 List containers  pull               Pulls service images  restart            Restart services  rm                 Remove stopped containers  run                Run a one-off command  scale              Set number of containers for a service  start              Start services  stop               Stop services  up                 Create and start containers  migrate-to-labels  Recreate containers to add labels

然后 docker-compose 就可以正常使用了
