Docker Compose是一个部署多个容器的简单但是非常必要的工具，在实际工作中非常有价值，相信随着Docker Compose的完善，其必将取代docker run成为开发者启动docker容器的首选。

BUG

使用curl安装遇到证书问题

# curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:02 --:--:--     0curl: (77) error setting certificate verify locations:
  CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none

Debug

• 尝试一

tried uninstalling and reinstalling curl in Ubuntu, and updating my CA certs with $ sudo update-ca-certificates --fresh which updated the certs。 依旧报如上的错误

• 尝试二

from googling, the CAfile location it is looking for is not correct for Ubuntu (and it doesn’t exist on my computer), while ` /etc/ssl/certs/ca-certificates.crt ` is the proper location. Most of the solutions involved setting the environment variable CURL_CA_BUNDLE to the proper location(I don’t know how to set), or adding cacert=/etc/ssl/certs/ca-certificates.crt to the (newly created) .curlrc file in my home directory(vim amy/.curlrc and root/.curlrc together).

root@ubuntu-host2:~# sudo vim ~/.curlrc
~cacert=/etc/ssl/certs/ca-certificates.crt
~

root@ubuntu-host2:~# source ~/.curlrc
root@ubuntu-host2:~# curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

root@ubuntu-host2:~# chmod +x /usr/local/bin/docker-compose
root@ubuntu-host2:~# docker-compose --version
docker-compose version 1.8.0, build f3628c7

Here 安转完成。Bravo！！

也可以使用pip安装

若使用pip 从 pypi 安装，最好使用virtualenv避免各个版本编译器冲突。

Compose can be installed from pypi using pip. If you install using pip it is highly recommended that you use a virtualenv because many operating systems have python system packages that conflict with docker-compose dependencies. See the virtualenv tutorial to get started.
