From 184c836a16e9954a2cba11ae21f07923077ec904 Mon Sep 17 00:00:00 2001 From: James Falcon Date: Mon, 19 Jul 2021 14:13:21 -0500 Subject: Initial hotplug support (#936) Adds a udev script which will invoke a hotplug hook script on all net add events. The script will write some udev arguments to a systemd FIFO socket (to ensure we have only instance of cloud-init running at a time), which is then read by a new service that calls a new 'cloud-init devel hotplug-hook' command to handle the new event. This hotplug-hook command will: - Fetch the pickled datsource - Verify that the hotplug event is supported/enabled - Update the metadata for the datasource - Ensure the hotplugged device exists within the datasource - Apply the config change on the datasource metadata - Bring up the new interface (or apply global network configuration) - Save the updated metadata back to the pickle cache Also scattered in some unrelated typing where helpful --- cloudinit/cmd/devel/parser.py | 3 +++ 1 file changed, 3 insertions(+) (limited to 'cloudinit/cmd/devel/parser.py') diff --git a/cloudinit/cmd/devel/parser.py b/cloudinit/cmd/devel/parser.py index 1a3c46a4..be304630 100644 --- a/cloudinit/cmd/devel/parser.py +++ b/cloudinit/cmd/devel/parser.py @@ -7,6 +7,7 @@ import argparse from cloudinit.config import schema +from . import hotplug_hook from . import net_convert from . import render from . import make_mime @@ -21,6 +22,8 @@ def get_parser(parser=None): subparsers.required = True subcmds = [ + (hotplug_hook.NAME, hotplug_hook.__doc__, + hotplug_hook.get_parser, hotplug_hook.handle_args), ('schema', 'Validate cloud-config files for document schema', schema.get_parser, schema.handle_schema_args), (net_convert.NAME, net_convert.__doc__, -- cgit v1.2.3
