我做了更多的研究，并且似乎使用了更好的关键词，因为我现在找到了解决方案。我想与所有人共享该解决方案，以防其他人可能需要它。

I did a bit more research and seem to have used better key words because I found my solution now. I wanted to share the solution with everyone, in case someone else may ever need it.

• 创建用于通过systemd配置docker服务的文件夹

• Create folder for configuring docker service through systemd

mkdir /etc/systemd/system/docker.service.d

在 /etc/systemd/system/docker.service.d/http-proxy.conf 中创建服务配置文件，并将以下内容放入新创建的文件

Create service configuration file at /etc/systemd/system/docker.service.d/http-proxy.conf and put the following in the newly created file

[Service]
 # NO_PROXY is optional and can be removed if not needed
 # Change proxy_url to your proxy IP or FQDN and proxy_port to your proxy port
 # For Proxy server which require username and password authentication, just add the proper username and password to the URL. (see example below)

 # Example without authentication
 Environment="HTTP_PROXY=http://proxy_url:proxy_port" "NO_PROXY=localhost,127.0.0.0/8"

 # Example with authentication
 Environment="HTTP_PROXY=http://username:password@proxy_url:proxy_port" "NO_PROXY=localhost,127.0.0.0/8"

• 重新加载systemctl以便读取新设置

  • Reload systemctl so that new settings are read

    sudo systemctl daemon-reload

    验证docker服务环境是否为正确设置

    Verify that docker service Environment is properly set

    sudo systemctl show docker --property Environment

    重新启动docker服务，使其使用更新的环境设置

    Restart docker service so that it uses updated Environment settings

    sudo systemctl重新启动docker

    现在，您可以在计算机上执行 docker-compose 命令，而无需获取任何连接被拒绝错误消息。

    Now you can execute the docker-compose command on your machine without getting any connection refused error messages.
