** Description changed:
[Impact]
cloud-init can no longer process cloud-config that specify a 'packages'
value. This affects any tools (Juju, MAAS) that rely on cloud-init to
install various packages as part of its first-boot. This seems to
trigger when specifying apt_sources in cloud-init.
[Test Case]
Create a userdata file:
cat >>/tmp/ud.txt
#cloud-config
apt_sources:
- {source: 'ppa:openstack-ubuntu-testing/folsom-trunk-testing'}
apt_update: true
apt_upgrade: false
packages: [python-novaclient]
<<END
- Boot a quantal or precise Ubuntu Cloud image, specifying the ud.txt as
- user-data:
+ Boot a precise daily Ubuntu Cloud image, specifying the ud.txt as user-
+ data:
euca-run-instances -k adam -t m1.tiny -f /tmp/ud.txt ami-04d
Allow instance to boot. Since MAAS provisiongs nodes on-the-fly, first
boot will have the affected cloud-init version and the attached
traceback in /var/log/cloud-init-output.log.
For cloud instances, its most likely running an older version of cloud-
init and the cloud-config was processed okay on first boot. To test the
affected version there, ssh to the machine:
# revert changes to system from initial cloud-init run.
$ sudo dpkg -P python-novaclient ;\
- sudo rm -rf
/etc/apt/sources.list.d/openstack-ubuntu-testing-folsom-trunk-testing-precise.list
;\
- sudo rm -rf /var/lib/cloud/*
+ sudo rm -rf
/etc/apt/sources.list.d/openstack-ubuntu-testing-folsom-trunk-testing-precise.list
;\
+ sudo rm -rf /var/lib/cloud/*
# Install cloud-init from precise-updates
$ sudo apt-get install cloud-init=0.6.3-0ubuntu1.3
# re-run cloud-init
$ sudo cloud-init start-local ; sudo cloud-init start; sudo cloud-init-cfg
all config ; sudo cloud-init-cfg all final
Observe traceback ending in "TypeError: add_sources() takes at most 2
arguments (3 given)", the expected package was not reinstalled.
Apply fix to
/usr/share/pyshared/cloudinit/CloudConfig/cc_apt_update_upgrade.py and re-run
cloud-init. Works as
expected, package is reinstalled.
[Regression Potential]
Minimal, simple one-line.
[Original Report]
Noticed juju deployed services were failing to come up using Juju+MAAS
and the newly released cloud-init SRU for 12.04. The node provisioned
thru MAAS okay, but after first boot did not have the required agents
installed. On further investigation, it looks like the required juju
packages were never installed. /var/log/cloud-init-output.log shows
the following traceback:
The key fingerprint is:
