The amount of code to do user and group normalization
and extraction deserves its own file so move the code
that does this to a new file and update references to the
old location.
This removes some of the funkyness done in config modules
to avoid namespace and attribute clashes as well.

* debian/cloud-init.templates: enable DigitalOcean by default
|
|
Added DigitalOcean to the default templates as enabled by default.
This allows cloud-init to work out of the box on DigitalOcean droplets.
|
|
Just add DigitalOcean to the list of datasources that are used
if there is no 'datasource_list' provided in config.
|
|
cloud-init-local needs to be run before net (and in the boot runlevel)
as it sets up networking config and adds it to the default runlevel.
cloud-init-local needs to be run in the boot runlevel because it
modifies services in the default runlevel. When a runlevel is started
it is cached, so modifications that happen to the current runlevel while
you are in it are not acted upon.
cloud-init needs to run after net, it does not need net because we still
want it to set up other things if it can.

This just looks in one other maas related path for a config file.
The file '91_kernel_cmdline_url' is written by cloud-init when it
gets a cloud-config-url parameter.
Also now we read the config even if a url is specified to potentially
fill in credentials.

This silences a warning made by Cheetah in pip installed environments:
UserWarning: You don't have the C version of NameMapper installed!
I'm disabling Cheetah's useStackFrames option ...
The reason for the monkey patching is that the warning goes to stderr
during nose and breaks up its expected output. The side affect of it
is that tests would run with Cheetah's 'useStackFrames'
enabled which is "painfully slow with the Python version of NameMapper".

The change reported to fix bug 1629797 was incorrect. It added:
Before=dbus.target
and its commit message referenced dbus.service.
dbus.target does not exist, and dbus.service would not solve the
problem. The change did not fix the problem nor actually make any
difference.
The fix here is just to use Before=dbus.socket.

This is the best work around we have for an issue seen when dns is used
during cloud-init.service on a system that is configured in nsswitch
to use systemd-resolved. The problem is that cloud-init.service was
blocking basic.target, and dbus would not be available until after
cloud-init.service finished.

Some of the new DigitalOcean unittests were written to use 'assert_called',
which is only available in mock versions 2.0. Because of this, the failure
would only occur in releases less than yakkety and not in 'tox'.
Add a 'xenial' entry to tox.ini with versions from xenial.

add 6d1edc3f5a1 to

This adds lots of config module documentation in a standard format.
It will greatly improve the content at readthedocs.
Additionally:
* Add a 'doc' env to tox.ini
* Changed default highlight language for sphinx conf from python to yaml
most examples in documentation are yaml configs
* Updated datasource examples to highlight sh code properly

Prior to LXD 2.3, the bridge configuration was done through distro
packaging. Thus, lxd module interacted with debconf.
With 2.3 and higher, this is now done inside LXD itself, so we
need to use "lxc network" there.
For now, this perfectly matches what we had before with debconf and
doesn't cover any of the new options. We can always add those later.
A set of tests similar to what we had for debconf has been added to make
sure things look good.
This is tested in Yakkety container running LXD 2.3 and all options seem
to be passed through as expected, giving me the bridge I defined.

On DigitalOcean, Network information is provided via Meta-data.
It changes the datasource to be a local datasource, meaning it
will run before fallback networking is configured.
The advantage of that is that before networking is configured it
can bring up a network device with ipv4 link-local and hit the
metadata service that lives at 169.254.169.254 to find its networking
configuration. It then takes down the link local address and lets
cloud-init configure networking.
The configuring of a network device to go looking for a metadata
service is gated by a check of data in the smbios. This guarantees
that the code will not run on another system.

since ntp module may try to install packages, it needs to run after
apt is configured.

The test in decode_binary for six.text_type was incorrect as that includes
unicode type in Python 2 which should actually be decoded.
When the type is string_types we now properly check only for basestring and
str in Python 2 and Python 3 respectively and return the given blob without
making an attempt to decode.

If device has no partition table, the first line of output from `sgdisk
-p <device>` will be "Creating new GPT entries.", instead of something
like "Disk /dev/sdb: 266338304 sectors, 127.0 GiB".
Also, protect against localized output by adjusting subp calls that
parse sgdisk output to set LANG=C.
|
|
In order for a caller to use 'env' argument of subp, they
will realistically do:
env = os.environ.copy()
env['FOO'] = 'BZR'
subp(cmd, env=env)
This shortens that to be:
subp(cmd, update_env={'FOO': 'BZR'})
Add tests, and update growpart tests to use mock when playing with
os.environ.

This adds support for understanding 'dhcp6' as a protocol
that can be written into /run/net-IFACE.cfg files by the initramfs.
The end result is supporting ipv6 dhcp from initramfs boot
all the way into iscsi root.

The end result of all of these changes is to get mounts managed by
cloud-init to occur only after cloud-init.service is done. We need to do
that so that filesystems that are set up by cloud-init (in disk_setup)
do not get mounted by stale entries in /etc/fstab before
the setup occurs.
This can occur in 2 ways:
a.) new instance with old /etc/fstab
b.) same instance where disk needs adjusting (Azure resize will re-format
the ephemeral disk).
The list of changes here is:
- move mounts and disk_setup module to cloud-init.service rather
than config. cloud-init.service runs earlier in boot so it
can get those mount points done earlier.
- on systemd add 'x-systemd.requires=cloud-init.service' to fstab options
- cloud-init-local.service: add Before=basic.target
- cloud-init.service:
- extend After, Before, and Wants to multiple lines rather than one
long line.
- sort consistently with cloud-init-local.service
- add DefaultDependencies=no
- add Before=default.target
- add Conflicts=shutdown.target

Dmidecode is not going to run successfully on anything other than an
x86 or x86_64, just avoid running it anywhere else.

When we moved cloud-final.service to run After multi-user.target it
caused a dependency loop (as cloud-init.target was still implied to be
Before multi-user.target).
journalctl would either show:
cloud-init.target: Breaking ordering cycle by deleting job
cloud-final.service/start
or
multi-user.target: Breaking ordering cycle by deleting job
cloud-init.target/start
The fix here is to clearly state that cloud-init.target is also
After multi-user.target
