Docker Compose 依赖 Docker Engine 进行任何有意义的工作，因此请确保根据您的设置，在本地或远程安装了 Docker Engine。

Install using pip

For alpine, the following dependency packages are needed: py-pip, python3-dev, libffi-dev, openssl-dev, gcc, libc-dev, rust, cargo, and make.

Compose can be installed from pypi using pip. If you install using pip, we recommend 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.

$upstream_addr

保留 IP 地址和端口，或上游服务器的 UNIX 域套接字的路径。如果在请求处理期间联系了多个服务器，则它们的地址用逗号分隔，例如“ 192.168.1.1:80, 192.168.1.2:80, unix:/tmp/sock”。如果发生从一个服务器组到另一个服务器组的内部重定向，由“X-Accel-Redirect”或 error_page 发起，则来自不同组的服务器地址用冒号分隔，例如“ 192.168.1.1:80, 192.168.1.2:80, unix:/tmp/sock : 192.168.10.1:80, 192.168.10.2:80”。如果无法选择服务器，该变量将保留服务器组的名称。

$proxy_port

proxy_pass指令中指定的代理服务器的端口 ，或协议的默认端口；
