From 91e423a36928ee5ea52de0b6836d0c34cc20fdd2 Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Tue, 2 Mar 2010 14:10:55 -0500 Subject: purge cache in cloud-init so it doesn't end up persisting across instances The cache file location is not instance specific. As such, if it is not cleaned from the image, a re-bundle would get the old data. To avoid that, clear the cache in cloud-init. --- cloudinit/__init__.py | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'cloudinit') diff --git a/cloudinit/__init__.py b/cloudinit/__init__.py index 8d6ec59e..1d8a1898 100644 --- a/cloudinit/__init__.py +++ b/cloudinit/__init__.py @@ -318,3 +318,13 @@ class CloudInit: def device_name_to_device(self,name): return(self.datasource.device_name_to_device(name)) + + +def purge_cache(): + try: + os.unlink(data_source_cache) + except OSError as e: + if e.errno != errno.ENOENT: return(False) + except: + return(False) + return(True) -- cgit v1.2.3
