Docker is a client-server application, and the server side affects things done directly by the server. From the documentation, that includes:

The daemon uses a proxy server to access images stored on Docker Hub and other registries, and to reach other nodes in a Docker swarm.

For configuring the client side, and the configuration of deployed containers, there is a second proxy configuration you need to perform in ~/.docker/config.json:

{
 "proxies": {
   "default": {
     "httpProxy": "http://proxy.example.com:3128",
     "httpsProxy": "https://proxy.example.com:3129",
     "noProxy": "*.test.example.com,.example.org,127.0.0.0/8"
   }
 }
}
