From 3cee0bf85fbf12d272422c8eeed63bf06e64570b Mon Sep 17 00:00:00 2001 From: Chad Smith Date: Tue, 31 Jul 2018 18:44:12 +0000 Subject: oracle: fix detect_openstack to report True on OracleCloud.com DMI data The OpenStack datasource in 18.3 changed to detect data in the init-local stage instead of init-network and attempted to redetect OpenStackLocal datasource on Oracle across reboots. The function detect_openstack was added to quickly detect whether a platform is OpenStack based on dmi product_name or chassis_asset_tag and it was a bit too strict for Oracle in checking for 'OpenStack Nova'/'Compute' DMI product_name. Oracle's DMI product_name reports 'SAtandard PC (i440FX + PIIX, 1996)' and DMI chassis_asset_tag is 'OracleCloud.com'. detect_openstack function now adds 'OracleCloud.com' as a supported value 'OracleCloud.com' to valid chassis-asset-tags for the OpenStack datasource.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Azure datasource now queries IMDS metadata service for network configuration at link local address http://169.254.169.254/metadata/instance?api-version=2017-12-01. The azure metadata service presents a list of macs and allocated ip addresses associated with this instance. Azure will now also regenerate network configuration on every boot because it subscribes to EventType.BOOT maintenance events as well as the 'first boot' EventType.BOOT_NEW_INSTANCE. For testing add azure-imds --kind to cloud-init devel net_convert tool for debugging IMDS metadata. Also refactor _get_data into 3 discrete methods:   - is_platform_viable: check quickly whether the datasource is     potentially compatible with the platform on which is is running   - crawl_metadata: walk all potential metadata candidates, returning a     structured dict of all metadata and userdata. Raise InvalidMetaData on     error.   - _get_data: call crawl_metadata and process results or error. Cache     instance data on class attributes: metadata, userdata_raw etc. --- cloudinit/cmd/devel/net_convert.py | 9 +- cloudinit/sources/DataSourceAzure.py | 256 +++++++++++++++-- tests/unittests/test_datasource/test_azure.py | 399 ++++++++++++++++++++++++-- 3 files changed, 605 insertions(+), 59 deletions(-) (limited to 'tests/unittests/test_datasource') diff --git a/cloudinit/cmd/devel/net_convert.py b/cloudinit/cmd/devel/net_convert.py index 1ec08a3c..271dc5ed 100755 --- a/cloudinit/cmd/devel/net_convert.py +++ b/cloudinit/cmd/devel/net_convert.py @@ -8,6 +8,7 @@ import sys import yaml from cloudinit.sources.helpers import openstack +from cloudinit.sources import DataSourceAzure as azure from cloudinit.net import eni, netplan, network_state, sysconfig from cloudinit import log @@ -28,7 +29,8 @@ def get_parser(parser=None): parser.add_argument("-p", "--network-data", type=open, metavar="PATH", required=True) parser.add_argument("-k", "--kind", - choices=['eni', 'network_data.json', 'yaml'], + choices=['eni', 'network_data.json', 'yaml', + 'azure-imds'], required=True) parser.add_argument("-d", "--directory", metavar="PATH", @@ -78,10 +80,13 @@ def handle_args(name, args): ["Input YAML", yaml.dump(pre_ns, default_flow_style=False, indent=4), ""])) ns = network_state.parse_net_config_data(pre_ns) - else: + elif args.kind == 'network_data.json': pre_ns = openstack.convert_net_json( json.loads(net_data), known_macs=known_macs) ns = network_state.parse_net_config_data(pre_ns) + elif args.kind == 'azure-imds': + pre_ns = azure.parse_network_config(json.loads(net_data)) + ns = network_state.parse_net_config_data(pre_ns) if not ns: raise RuntimeError("No valid network_state object created from" diff --git a/cloudinit/sources/DataSourceAzure.py b/cloudinit/sources/DataSourceAzure.py index 7007d9ea..783445e1 100644 --- a/cloudinit/sources/DataSourceAzure.py +++ b/cloudinit/sources/DataSourceAzure.py @@ -8,6 +8,7 @@ import base64 import contextlib import crypt from functools import partial +import json import os import os.path import re @@ -17,6 +18,7 @@ import xml.etree.ElementTree as ET from cloudinit import log as logging from cloudinit import net +from cloudinit.event import EventType from cloudinit.net.dhcp import EphemeralDHCPv4 from cloudinit import sources from cloudinit.sources.helpers.azure import get_metadata_from_fabric @@ -49,7 +51,17 @@ DEFAULT_FS = 'ext4' AZURE_CHASSIS_ASSET_TAG = '7783-7084-3265-9085-8269-3286-77' REPROVISION_MARKER_FILE = "/var/lib/cloud/data/poll_imds" REPORTED_READY_MARKER_FILE = "/var/lib/cloud/data/reported_ready" -IMDS_URL = "http://169.254.169.254/metadata/reprovisiondata" +AGENT_SEED_DIR = '/var/lib/waagent' +IMDS_URL = "http://169.254.169.254/metadata/" + +# List of static scripts and network config artifacts created by +# stock ubuntu suported images. +UBUNTU_EXTENDED_NETWORK_SCRIPTS = [ + '/etc/netplan/90-azure-hotplug.yaml', + '/usr/local/sbin/ephemeral_eth.sh', + '/etc/udev/rules.d/10-net-device-added.rules', + '/run/network/interfaces.ephemeral.d', +] def find_storvscid_from_sysctl_pnpinfo(sysctl_out, deviceid): @@ -185,7 +197,7 @@ if util.is_FreeBSD(): BUILTIN_DS_CONFIG = { 'agent_command': AGENT_START_BUILTIN, - 'data_dir': "/var/lib/waagent", + 'data_dir': AGENT_SEED_DIR, 'set_hostname': True, 'hostname_bounce': { 'interface': DEFAULT_PRIMARY_NIC, @@ -252,6 +264,7 @@ class DataSourceAzure(sources.DataSource): dsname = 'Azure' _negotiated = False + _metadata_imds = sources.UNSET def __init__(self, sys_cfg, distro, paths): sources.DataSource.__init__(self, sys_cfg, distro, paths) @@ -263,6 +276,8 @@ class DataSourceAzure(sources.DataSource): BUILTIN_DS_CONFIG]) self.dhclient_lease_file = self.ds_cfg.get('dhclient_lease_file') self._network_config = None + # Regenerate network config new_instance boot and every boot + self.update_events['network'].add(EventType.BOOT) def __str__(self): root = sources.DataSource.__str__(self) @@ -336,15 +351,17 @@ class DataSourceAzure(sources.DataSource): metadata['public-keys'] = key_value or pubkeys_from_crt_files(fp_files) return metadata - def _get_data(self): + def crawl_metadata(self): + """Walk all instance metadata sources returning a dict on success. + + @return: A dictionary of any metadata content for this instance. + @raise: InvalidMetaDataException when the expected metadata service is + unavailable, broken or disabled. + """ + crawled_data = {} # azure removes/ejects the cdrom containing the ovf-env.xml # file on reboot.

16:02:25 +0000 Subject: tests: Disallow use of util.subp except for where needed. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In many cases, cloud-init uses 'util.subp' to run a subprocess. This is not really desirable in our unit tests as it makes the tests dependent upon existance of those utilities. The change here is to modify the base test case class (CiTestCase) to raise exception any time subp is called. Then, fix all callers. For cases where subp is necessary or actually desired, we can use it via   a.) context hander CiTestCase.allow_subp(value)   b.) class level self.allowed_subp = value Both cases the value is a list of acceptable executable names that will be called (essentially argv[0]). Some cleanups in AltCloud were done as the code was being updated. --- cloudinit/analyze/tests/test_dump.py | 86 ++++++++------------ cloudinit/cmd/tests/test_status.py | 6 +- cloudinit/config/tests/test_snap.py | 7 +- cloudinit/config/tests/test_ubuntu_advantage.py | 7 +- cloudinit/net/tests/test_init.py | 2 + cloudinit/sources/DataSourceAltCloud.py | 24 +++--- cloudinit/sources/DataSourceSmartOS.py | 29 ++++--- cloudinit/tests/helpers.py | 43 ++++++++++ tests/unittests/test_datasource/test_altcloud.py | 44 +++++----- tests/unittests/test_datasource/test_cloudsigma.py | 3 + .../unittests/test_datasource/test_configdrive.py | 3 + tests/unittests/test_datasource/test_nocloud.py | 2 + tests/unittests/test_datasource/test_opennebula.py | 1 + tests/unittests/test_datasource/test_ovf.py | 8 +- tests/unittests/test_datasource/test_smartos.py | 94 +++++++++++++++------- tests/unittests/test_ds_identify.py | 1 + .../test_handler/test_handler_apt_source_v3.py | 11 ++- .../unittests/test_handler/test_handler_bootcmd.py | 10 ++- tests/unittests/test_handler/test_handler_chef.py | 18 +++-- .../test_handler/test_handler_resizefs.py | 8 +- tests/unittests/test_handler/test_schema.py | 12 ++- tests/unittests/test_net.py | 18 ++++- tests/unittests/test_util.py | 27 ++++--- 23 files changed, 289 insertions(+), 175 deletions(-) (limited to 'tests/unittests/test_datasource') diff --git a/cloudinit/analyze/tests/test_dump.py b/cloudinit/analyze/tests/test_dump.py index f4c42841..db2a667b 100644 --- a/cloudinit/analyze/tests/test_dump.py +++ b/cloudinit/analyze/tests/test_dump.py @@ -5,8 +5,8 @@ from textwrap import dedent from cloudinit.analyze.dump import ( dump_events, parse_ci_logline, parse_timestamp) -from cloudinit.util import subp, write_file -from cloudinit.tests.helpers import CiTestCase +from cloudinit.util import which, write_file +from cloudinit.tests.helpers import CiTestCase, mock, skipIf class TestParseTimestamp(CiTestCase): @@ -15,21 +15,9 @@ class TestParseTimestamp(CiTestCase): """Logs with cloud-init detailed formats will be properly parsed.""" trusty_fmt = '%Y-%m-%d %H:%M:%S,%f' trusty_stamp = '2016-09-12 14:39:20,839' - - parsed = parse_timestamp(trusty_stamp) - - # convert ourselves dt = datetime.strptime(trusty_stamp, trusty_fmt) - expected = float(dt.strftime('%s.%f')) - - # use date(1) - out, _err = subp(['date', '+%s.%3N', '-d', trusty_stamp]) - timestamp = out.strip() - date_ts = float(timestamp) - - self.assertEqual(expected, parsed) - self.assertEqual(expected, date_ts) - self.assertEqual(date_ts, parsed) + self.assertEqual( + float(dt.strftime('%s.%f')), parse_timestamp(trusty_stamp)) def test_parse_timestamp_handles_syslog_adding_year(self): """Syslog timestamps lack a year.
