make check fails in a trusty sbuild due to different rules on older pep8.
Fix formatting to pass in older and newer pep8.

This replaces the use of SharedConfig.xml in both the walinuxagent case,
and the case where we communicate with the Azure fabric ourselves.
|
|
Azure has or will be offering shortly the ability to directly define the SSH
key value instead of a fingerprint in the ovf-env.xml file. This patch
favors defined SSH keys over the fingerprint method (LP: #1506244).

Azure's ephemeral disks are not guaranteed to be assigned the same name by
the kernel every boot. This causes problems on ~2% of Azure instances, and
can be fixed by using udev rules to give us a deterministic path to mount;
this patch introduces those udev rules and modifies the Azure data source
to use them.
Changes to a couple of config modules were also required. In some places,
they just needed to learn to dereference symlinks. In cc_mounts this
wasn't sufficient because the dereferenced device would have been put in
/etc/fstab (rather defeating the point of using the udev rules in the
first place). A fairly hefty refactor was required to separate "is this a
valid block device?" from "what shall I put in fstab?".
LP: #1411582

The ephemeral disk will not necessarily be assigned the same name at
each boot (LP: #1411582), so we use some udev rules to ensure we always
get the right one.

The fabric provides the user password in plain text via the CDROM,
and cloud-init has previously wrote the ovf-env.xml in /var/lib/waagent
with the password in plain text. This change redacts the password.

Including minor refactoring to make mocking considerably easier.
|
|
just seems to make more sense to decode here.
Add a test showing the previous failure (testBytesInPayload)
And one that should pass (testStringInPayload)
Also, add a test for unencoded content in the ovf xml (test_userdata_plain)
And explicitly set encoding on another test (test_userdata_found).
|
|
This should fix the Azure data source on Python 3, and is appropriate as
XML shouldn't really be read as a string.
|
|
- Refactor both the base64 encoding and decoding into utility functions.
Also:
- Mechanically fix some other broken untested code.

might have to rewrite this for Python 2.6.
Disable Cepko tests (test_cs_util.py) since they are essentially worthless.
Convert test_azure to unittest.mock.
|
|
|
|
Fixed all complaints from running "make pep8". Also version locked
pep8 in test-requirements.txt to ensure that pep8 requirements don't
change without an explicit commit.

Modified cc_mounts to identify whether ephermalX is partitioned.
Changed datasources for Azure and SmartOS to use 'ephemeralX.Y' format.
Added disk remove functionally

Also
* cloudinit/sources/DataSourceAzure.py: invalid xml in a file called
'ovfenv.xml' should raise BrokenAzureDatasource rather than
NonAzureDataSource
* cloudinit/sources/DataSourceSmartOS.py:
cloudinit/sources/DataSourceAzure.py
use 'ephemeral0' as the device name in builtin fs_setup
* tests/unittests/test_datasource/test_azure.py:
* always patch 'list_possible_azure_ds_devs' as it calls find_devs_with
which calls blkid, and dramatically was slowing down tests on my system.
* test_user_cfg_set_agent_command_plain:
fix this test to not depend on specific format of yaml.dumps().
* test_userdata_arrives: add a test that user-data makes it through

'password' was the wrong key. It should have been setting the default
user's "plain_text_password".
Instead of doing that, though, we're encrypting the value and putting it in
'passwd', which will then be passed on to useradd. The key value in doing
this is that the plain text password will not be stored in obj.pkl.
(admittedly it is still in plain text in the ovf-env.xml file).

See the added doc/sources/azure/README.rst for why this is necessary.
Essentially, we now are doing the following in the get_data() method
of azure datasource to publish this NewHostname:
hostname NewHostName
ifdown eth0;
ifup eth0

The walinux agent expects that the files it writes with 0644 (default umask)
permissions are not globally readable. Since we were creating the directory
for it, and using default umaks (0755), the files inside were readable to
non-priviledged users.
|
|
|
|
|
|
now if there are pubkeys, the cfg['_pubkeys'] entry
will have a list of dicts where each dict has 'fingerprint' and 'path'
entries.
The next thing to do is to block waiting for the <fingerprint>.crt
files to appear in /var/lib/waagent.
|
|
this will copy the ovf-env.xml file that was found to
the configured directory (default /var/lib/waagent)
