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/DataSourceEc2.py | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'cloudinit/sources/DataSourceEc2.py') diff --git a/cloudinit/sources/DataSourceEc2.py b/cloudinit/sources/DataSourceEc2.py index 8a7f7c60..700437b0 100644 --- a/cloudinit/sources/DataSourceEc2.py +++ b/cloudinit/sources/DataSourceEc2.py @@ -76,6 +76,13 @@ class DataSourceEc2(sources.DataSource): # Whether we want to get network configuration from the metadata service. perform_dhcp_setup = False + supported_update_events = {EventScope.NETWORK: { + EventType.BOOT_NEW_INSTANCE, + EventType.BOOT, + EventType.BOOT_LEGACY, + EventType.HOTPLUG, + }} + def __init__(self, sys_cfg, distro, paths): super(DataSourceEc2, self).__init__(sys_cfg, distro, paths) self.metadata_address = None -- cgit v1.2.3
