I often found myself redownloading the same package of lxc instances when failed and retried to reinstall the openstack-install either using the Landscape, single, or multi modes options, which take time on slow connection. Juju bootstrapping does not obey the system-wide proxy when downloading the packages, instances, and/or lxc containers it needs. Fortunately, the MaaS installation is now set up manually so we can define MAAS_HTTP_PROXY within the MAAS GUI.
I've setup the /etc/environment, /etc/apt/apt.conf, and /etc/wgetrc to use proxy server in local network but the tool ignores the setting and goes right through the internet each time it's reinstalled or redeployed.
How can I configure the openstack-install to obey system-wide network proxy setting so all the download packages, instances, and containers be cached in squid for easier and faster deployment?
