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/event.py | 1 + 1 file changed, 1 insertion(+) (limited to 'cloudinit/event.py') diff --git a/cloudinit/event.py b/cloudinit/event.py index 76a0afc6..53ad4c25 100644 --- a/cloudinit/event.py +++ b/cloudinit/event.py @@ -29,6 +29,7 @@ class EventType(Enum): BOOT = "boot" BOOT_NEW_INSTANCE = "boot-new-instance" BOOT_LEGACY = "boot-legacy" + HOTPLUG = 'hotplug' def __str__(self): # pylint: disable=invalid-str-returned return self.value -- cgit v1.2.3
