sunbeam prepare-node-script --bootstrap do not set up proxy for juju

[Francesco De Simone]

Trying to set up sunbeam 2024.1/candidate under a proxy, but the
```sunbeam prepare-node-script --bootstrap```

didn't not set any proxy for juju

https://github.com/canonical/snap-openstack/blob/e4311a3d9a4cba7204466b7177a385d519bb571f/sunbeam-python/sunbeam/commands/prepare_node.py#L157

 sudo --user $USER juju bootstrap localhost

this should set the proxy for apt and snaps

There is more to this than just setting the juju proxy, this actually requires to download the charm and bootstrap from this downloaded charm.

This workaround is actually what MAAS mode does automatically.

[Nobuto Murata (nobuto)]

hmm, deploying and managing a cluster behind HTTP Proxy and doing so in an offline / air-gapped manner or in a controlled network are two separate use cases though. In a scenario behind the HTTP Proxy, everything should be online as if the env has internet access.

[Guillaume Boutry (gboutry)]

Not really because of a bug in juju: https://bugs.launchpad.net/juju/+bug/2044481

[Nobuto Murata (nobuto)]

Ah yeah, we are familiar with the bug. Just to let you know that we are not downloading the charms, etc. for Charmed OpenStack deployment as of today. We are juggling setting and unsetting proxy variables here and there and before and after doing something to workaround the bug above.

We are seeing the same behavior described below and have a work around.

Running `sunbeam prepare-node-script --bootstrap | bash -x && newgrp snap_daemon` does not set `NO_PROXY` in /etc/environment. It is not setting the specific IP of the first lxc juju controller "admin/controller".

Sunbeam only sets the CIDR, but for some reason the sunbeam script is not using it. When it needs to log to the Juju controller tcp request goes to `http_proxy` instead of the controller.

Workaround: Add the specific IP of the Juju controller lxc container in /etc/enviroment and re-run sunbeam prepare-node-script.
