## Proxy setup
systemProp.proxySet="true"
systemProp.http.keepAlive="true"
systemProp.http.proxyHost=host
systemProp.http.proxyPort=port
systemProp.http.proxyUser=username

Docker:

Native Docker
Depending on your OS, you have to edit a specific file (/etc/sysconfig/docker or /etc/default/docker).

Then, you have to restart the docker service with: sudo service docker restart.

It will not apply to systemd. See this page from docker to configure the proxy.

Docker with docker-machine
You can create your docker-machine with:

docker-machine create -d virtualbox \
    --engine-env HTTP_PROXY=http://username:password@host:port \
    --engine-env HTTPS_PROXY=http://username:password@host:port \
    default

Or you can edit the file ~/.docker/machine/machines/default/config.json.
