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/sources/DataSourceConfigDrive.py | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'cloudinit/sources/DataSourceConfigDrive.py') diff --git a/cloudinit/sources/DataSourceConfigDrive.py b/cloudinit/sources/DataSourceConfigDrive.py index 62756cf7..19c8d126 100644 --- a/cloudinit/sources/DataSourceConfigDrive.py +++ b/cloudinit/sources/DataSourceConfigDrive.py @@ -12,9 +12,8 @@ from cloudinit import log as logging from cloudinit import sources from cloudinit import subp from cloudinit import util - +from cloudinit.event import EventScope, EventType from cloudinit.net import eni - from cloudinit.sources.DataSourceIBMCloud import get_ibm_platform from cloudinit.sources.helpers import openstack @@ -37,6 +36,13 @@ class DataSourceConfigDrive(openstack.SourceMixin, sources.DataSource): dsname = 'ConfigDrive' + supported_update_events = {EventScope.NETWORK: { + EventType.BOOT_NEW_INSTANCE, + EventType.BOOT, + EventType.BOOT_LEGACY, + EventType.HOTPLUG, + }} + def __init__(self, sys_cfg, distro, paths): super(DataSourceConfigDrive, self).__init__(sys_cfg, distro, paths) self.source = None -- cgit v1.2.3
