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 --- packages/redhat/cloud-init.spec.in | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'packages') diff --git a/packages/redhat/cloud-init.spec.in b/packages/redhat/cloud-init.spec.in index 16138012..b930709b 100644 --- a/packages/redhat/cloud-init.spec.in +++ b/packages/redhat/cloud-init.spec.in @@ -119,6 +119,12 @@ version_pys=$(cd "$RPM_BUILD_ROOT" && find . -name version.py -type f) ( cd "$RPM_BUILD_ROOT" && sed -i "s,@@PACKAGED_VERSION@@,%{version}-%{release}," $version_pys ) +# patch hotplug /usr/libexec script path +hotplug_file=$(cd "$RPM_BUILD_ROOT" && find . -name 10-cloud-init-hook-hotplug.rules -type f) + +( cd "$RPM_BUILD_ROOT" && + sed -i "s,/usr/lib,%{_libexecdir}," $hotplug_file ) + %clean rm -rf $RPM_BUILD_ROOT @@ -172,6 +178,7 @@ fi %files /lib/udev/rules.d/66-azure-ephemeral.rules +/lib/udev/rules.d/10-cloud-init-hook-hotplug.rules %if "%{init_system}" == "systemd" /usr/lib/systemd/system-generators/cloud-init-generator -- cgit v1.2.3
