If user upgraded to new cloud-init and attempted to run 'cloud-init init'
without rebooting, cloud-init restores the datasource object from pickle.
The older version pickled datasource object had no value for
_network_config or fallback_nic. This caused the Ec2 datasource to attempt
to reconfigure networking with a None fallback_nic. The pickled object
also cached an older version of ec2 metadata which didn't contain network
information.
This branch does two things:
- Add a fallback_interface property to DatasourceEC2 to support reading the
old .fallback_nic attribute if it was set. New versions will
call net.find_fallback_nic() if there has not been one found.
- Re-crawl metadata if we are on Ec2 and don't have a 'network' key in
metadata

dhclient runs, obtains a address and then backgrounds itself.
cloud-init did not take care to kill it after it was done with it.
After it has run and created the leases, we can kill it.

On python 2.7 and earlier (CentOS 6 & 7), UrlErrors raised by requests do
not report the url which failed. In such cases, append the url if not
present in the error message.
This fixes nightly CI failures at

Without this the entire stage can fail, which will leave an instance
unaccessible.

The etc/hosts file is was not properly setup for openSUSE or SLES
when manage_etc_hosts is set in the config file.
Improve the doc to address the fact that the 'localhost' ip is
distribution dependent (not always 127.0.0.1).

The rh_subscription module doesn't perform null checks when attempting to

specified, cloud-init fails to run.

At present the location for the template file look up upon failure

We had used some dns records in i9n.brickies.net (my personal domain)
as a temporary solution until we got names registered in the cloud-init.io
namespace.
We now have CNAME records for:
ubuntu.i9n.cloud-init.io
cloudinit1.cloud-init.io
cloudinit2.cloud-init.io

Azure kernel now configures the SRIOV devices itself so cloud-init

3 things here:
a.) link to a bug that we opened to track what made us add
dns entries for hostname of our guests.
b.) spelling fix.
c.) raise an instance of a NotImplementedError not the class.

Integration test harness changes:
* Enable collection of console log in nocloud-kvm and lxd.
* Collect the console log to results for all test runs.
* change 'tmpfile' to pick name locally instead of using 'mktemp'.
* drop the 'instance' attribute from nocloud-kvm Image and
demote LXDImage.instance to a private attribute.
This is because Images do not actually have instances.
(LXDImage internally uses a booted system to modify the image).
* Add 'TargetBase' as a superclass of Image and Instance providing
implementations of execute, read_data, write_data, pull_file,
and push_file. These all depend on an implementation of _execute.
* Improve '_execute' implementations to support accepting stdin.
* execute supports 'rcs=False' meaning 'do not raise exception'.
* Drop support for pylxd < 2.2. older versions cannot determine
exit code of 'execute', which makes them unusable.
* make NoCloudKVMInstance._execute run as root via sudo. This required
some changes so that 'hostname' could be reverse-looked up in order
to avoid sudo taking a long time (~20 seconds).
* re-use existing ssh connection in nocloud-kvm.
Test changes here:
* do not use /tmp, but rather /var/tmp (LP: #1707222)
* make keys_to_console assertions more strict.
* change user test cases to always add default (ubuntu) user
so that nocloud-kvm's execute which operates over ssh can work.

A recent cleanup of the resizefs module broke resizing when a system was
booted with root=PARTUUID=<uuid> and the device /dev/root does not exist.
This path is exposed with the Ubuntu 16.04 but not with Ubuntu 17.10. A
recreate exists under bug 1684869.

During continuous integration tests, we're seeing quite a lot of
unreliablity when running 'yum install'. The change here is to move to
re-trying a run of 'yum install --downloadonly' for 10 times or until
it succeeds. Then afterwards, running yum install from the cache.
This seems safer in general than just re-trying an install operation,
since we are specifically affected by the download phase failing.
Also present are some flake8 fixes to tools/read-dependencies.

There was fallout in a full integration test run from my adding of
test_no_warnings_in_log which asserted that there could not be a WARNING
found in the /var/log/cloud-init.log
This fixes 2 of the cases:
* TestCommandOutputSimple had a valid WARNING written, so adjust its
test case to allow for that.
* TestLxdDir had a valid config in the test but the module would
log a WARNING, so fix the module.
Also updates lxd unit tests to look for WARN themselves.

Tests are currently run by creating a temporary subclass of each class
and then executing it (in get_suites). When running the tests suite
the output would contain the temporary class name. That was less than
useful, and made batch runs almost impossible to identify which
test case had an error.
This change goes from output of:
FAIL: test_no_warnings_in_log \
(tests.cloud_tests.testcases.get_suite.<locals>.tmp)
To
FAIL: test_no_warnings_in_log \
(tests.cloud_tests.testcases.modules.ntp.TestNtp)

Fix three things related to the ntp module:
1. Fix invalid cloud-config schema in the integration test which
provided empty dicts instead of emptylists for pools and servers
2. Correct logic in the ntp module to allow support for the minimal
cloud-config 'ntp:' without raising a RuntimeError. Docs and schema
definitions already describe that cloud-config's ntp can be empty.
An ntp configuration with neither pools nor servers will be
configured with a default set of ntp pools. As such, the ntp module
now officially allows the following ntp cloud-configs:
- ntp:
- ntp: {}
- ntp:
servers: []
pools: []
3. Add a simple unit test which validates all cloud-config provided to
our integration tests to ensure it adheres to any defined module
schema so as more jsonschema definitions are added, we validate our
integration test configs.

Per centos documentation using the fastestmirror plugin is effective at
finding the fastest mirror, unless you are behind a proxy. In that case
you should disable it. Therefore, in our tests if we are setting the proxy
we should also disable the fastestmirror plugin.
|
|
When operating in expected path, cloud-init should avoid logging with
warning. That causes 'WARNING' messages in /var/log/cloud-init.log.
By default, warnings also go to the console.
Since jsonschema is a optional dependency, and not present on xenial
and zesty, cloud-init should not warn there.
Also here:
* Add a test to integration tests to assert that there are no
warnings in /var/log/cloud-init.log.
* Update one integration test that did show warning and the related
documentation and examples.

Output in cloud-init-output.log contained only the string representation

Update unit tests to pass a 0 instead of 'off' to validate that network
state is properly written.

The tools that use "git describe" were just assuming a consisent
number of characters in the hash. It seems ubuntu 16.04 would use 7
and later versions use 8. To avoid that discrepency in developer
environments, set it to 8.

Update network_state to store the bridge_stp value as a boolean.
The various renderers then can map the boolean value to the correct
output as needed; eni uses 'on/off', sysconfig uses 'yes/no' and
netplan will use the boolean directly.
Update unittest values for sysconfig and netplan. Both contained the
network_state string value which resulted in not correctly enable/disable
STP in the target system.
Update network_state comment (fd -> forward-delay, add stp as boolean) on
bridge commands to match the expected format of a netplan bridge command.

With the addition of the nocloud-kvm support a few other python modules

Systems that used systemd-networkd's dhcp client would not be able to get
information on the Azure endpoint (placed in Option 245) or the CloudStack
server (in 'server_address').
The change here supports reading these files in /run/systemd/netif/leases.
The files declare that "This is private data. Do not parse.", but at this
point we do not have another option.

boto_utils.py had been removed some time ago, and the current
cloudinit/ec2_utils.py is not based on what was in boto_utils.
We just failed to remove the mention of it from the upstream

to get upstream and ubuntu in sync.

DataSourceOVF attempts to find iso files via walking os.listdir('/dev/')
which is far too wide. This approach is too invasive and can sometimes
race with systemd attempting to fsck and mount devices.
Instead, utilize cloudinit.util.find_devs_with to filter devices by
criteria (which uses blkid under the covers). This results in fewer
attempts to mount block devices which do not contain iso filesystems.
Unittest changes include:
- cloudinit.tests.helpers; introduce add_patch() helper
- Add unittest coverage for DataSourceOVF use of transport_iso9660

Here we commit the SuSE provided sysvinit scripts. They are very similar
to those in redhat/ directory. They differ in small but important ways.
Rather than build a template system here we will just accept the copy
and paste. sysvinit in both RedHat and SuSE is EOL, so we do not
expect any real maintenance cost here.

Create a copy of each modules schema attribute when generating sphinx docs
to avoid altering the actual module dict in memory. This avoids illegible
rendering of module examples and distros where each character of a list
was represented on a separate line by itself.
Fixes ntp, resizefs, runcmd and bootcmd docs.

The package cloudinit was sparsely added to only the makefile's unittest
target and tox's py3 target. This branch adds cloudinit package to 'make
unittest3' and all tox environments. It tweaks one cloudinit unit test to
use mocked_object.call_count instead of mocked_object.assert_called_once
which is not defined in some python unittest versions.

/run/cloud-init/tmp is on a filesystem mounted noexec, so running
dchlient in Ec2Local during discovery breaks with 'Permission denied'.

Currently the Azure data source waits up to 60 seconds. This has proven
not to be sufficient to provide resiliency to unrelated transient failures
in other parts of the infrastructure. Azure already has logic outside of
the VM to abort hung provisioning. This changes lengthens the time out to
15 minutes.
