2019-12-11ds_identify: if /sys is not available use dmidecode (#42)Igor Galić
On non-Linux systems, `/sys` won't be available. In these cases, we can query `dmidecode(8)` directly. This PR implements a dmi_decode function to query the same fields ds-identify would otherwise read from /sys. This path is taken when /sys isn't present. In addition to adding dmidecode support, non-Linux systems also need to map in virtualization detection as systemd-detect-virt is not present; on FreeBSD, use sysctl kern.vm_guest and provide a mapping[1] between BSD values and those that match with systemd-detect-virt[2]. 1. https://github.com/freebsd/freebsd/blob/master/sys/kern/subr_param.c#L149-L157 2. https://www.freedesktop.org/software/systemd/man/systemd-detect-virt.html LP: #1852442
2019-10-11Add Support for e24cloud to Ec2 datasource.Scott Moser
e24cloud provides an EC2 compatible datasource. This just identifies their platform based on dmi 'system-vendor' having 'e24cloud'. https://www.e24cloud.com/en/ . Updated chassis typo in zstack unit test docstring. LP: #1696476
2019-10-04Add RbxCloud datasourceAdam Dobrawy
2019-09-18Add datasource for ZStack platform.Shixin Ruan
Zstack platform provides a AWS Ec2 metadata service, and identifies their platform to the guest by setting the 'chassis asset tag' to a string that ends with '.zstack.io'. LP: #1841181
2019-09-11Brightbox: restrict detection to require full domain match .brightbox.comScott Moser
The detection for brightbox in both ds-identify and in identify_brightbox would incorrectly match the domain 'bobrightbox', which is not a brightbox platform. The fix here is to restrict matching to '*.brightbox.com' rather than '*brightbox.com' Also, while here remove a url to bug 1661693 which added the knowledge of brightbox.
2019-07-16Add a cdrom size checker for OVF ds to ds-identifyPengpeng Sun
With a large size ISO file attached to iso dev, ds-identify might grep it entirely if iso dev is ISO9660, it takes very long time to start OS. Resolve this by: - Adding a checker to read the ISO size (from sysfs). If the size of the ISO filesystem is > 10MiB then the ISO will be ignored (logged as oversized). - Move the ovf vmware guest customization checker to be ahead of cdrom ovf checker, so no need check the ISO size if vmware guest customization is enabled. LP: #1806701
2019-06-03Allow identification of OpenStack by Asset TagMark T. Voelker
When OpenStack is deployed on some hypervisors (such as VMware vSphere), cloud-init doesn't detect that it needs to probe the metadata service because the DMI product name field can't be set to a field that is recognized by cloud-init. However, the asset tag field can be set via flavor extra specs or image metadata. A similar approach is already used to identify Open Telekom Cloud. This patch allows cloud init to recognize "OpenStack Nova" or "OpenStack Compute" in the asset tag field as an indication that the instance being configured is running on an OpenStack platform. LP: #1669875
2019-04-09Change DataSourceNoCloud to ignore file system label's case.Risto Oikarinen
NoCloud data source now accepts both 'cidata' and 'CIDATA' as filesystem labels. This is similar to DataSourceConfigDrive's support for 'config-2' and 'CONFIG-2'.
2019-02-26tests: fix some slow tests and some leaking stateDaniel Watkins
In test_ds_identify, don't mutate otherwise-static test data. When running tests in a random order, this was causing failures due to breaking preconditions for other tests. In tests/helpers, reset logging level in tearDown. Some of the CLI tests set the level of the root logger in a way that isn't correctly reset. For test_poll_imds_re_dhcp_on_timeout and test_dhcp_discovery_run_in_sandbox_warns_invalid_pid, mock out time.sleep; this saves ~11 seconds (or ~40% of previous test time!).
2018-12-20Vmware: Add support for the com.vmware.guestInfo OVF transport.Scott Moser
This adds support for reading OVF information over the 'com.vmware.guestInfo' tranport. The current implementation requires vmware-rpctool be installed in the system. LP: #1807466
2018-11-27OVF: identify label iso9660 filesystems with label 'OVF ENV'.Scott Moser
When deploying an OVA, at least some versions of vmware attach a cdrom with an ISO9660 filesystem label of 'OVF ENV'. This was seen on Vmware vCenter Server, 6.0.0, 2776510. In order to accomplish this we had to change the content of the DI_ISO9660_DEVS variable to be comma delimited rather than space delimited.
2018-09-05tests: Disallow use of util.subp except for where needed.Scott Moser
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.
2018-08-17Add datasource Oracle Compute Infrastructure (OCI).Scott Moser
This adds a Oracle specific datasource that functions with OCI. It is a simplified version of the OpenStack metadata server with support for vendor-data. It does not support the OCI-C (classic) platform. Also here is a move of BrokenMetadata to common 'sources' as this was the third occurrence of that class.
2018-05-22ds-identify: ensure that we have certain tokens in PATH.Scott Moser
SuSE builds were not getting a PATH set in generator's environment. This may seem like mis-configuration on the system, but caused ds-identify to fail to find blkid (or any other program). The change here just ensures that we get /sbin /usr/sbin /bin /usr/bin into the PATH when main is run. LP: #1771382
2018-05-15ds-identify: recognize container-other as a container, test SmartOS.Scott Moser
In playing with a SmartOS container I found that ds-identify did not identify the container there as a container. Systemd-detect-virt identifies it as 'container-other'. Also here are tests for ds-identify for the SmartOS platform identification, and some indentation fixes in ds-identify.
2018-04-30IBMCloud: Disable config-drive and nocloud only if IBMCloud is enabled.Scott Moser
Ubuntu images on IBMCloud for 16.04 have some seed data in /var/lib/cloud/data/seed/nocloud-net. In order to have systems with IBMCloud enabled, we modified ds-identify detection to skip that seed if the system was on IBMCloud. That change did not consider the fact that IBMCloud might not be in the datasource list. There was similar logic in the ConfigDrive datasource in ds-identify and the datasource itself. Config drive is now updated to only check and avoid IBMCloud if IBMCloud is enabled. The check in ds-identify for nocloud was dropped. If a user provides a nocloud seed on IBMCloud, then that can be used. This means that systems running Xenial will continue to get their old datasources. LP: #1766401
2018-04-26IBMCloud: recognize provisioning environment during debug boots.Scott Moser
When images are deployed from template in a production environment the artifacts of the provisioning stage (provisioningConfiguration.cfg) that cloud-init referenced are cleaned up. However, when provisioned in "debug" mode (internal to IBM) the artifacts are left. This changes the 'is_ibm_provisioning' implementations in both ds-identify and in the IBM datasource to identify the provisioning stage more correctly. The change is to consider provisioning only if the provisioing file existed and there was no log file or the log file was older than this boot. LP: #1767166
2018-03-23IBMCloud: Initial IBM Cloud datasource.Scott Moser
This adds a specific IBM Cloud datasource. IBM Cloud is identified by: a.) running on xen b.) one of a LABEL=METADATA disk or a LABEL=config-2 disk with UUID=9796-932E The datasource contains its own config-drive reader that reads only the currently supported portion of config-drive needed for ibm cloud. During the provisioning boot, cloud-init is disabled. See the docstring in DataSourceIBMCloud.py for more more information.
2018-03-21Identify OpenTelekomCloud Xen as OpenStack DS.Kurt Garloff
Open Telekom Cloud gen1 (Xen) hosts do not provide nova product names in DMI but Xen HVM domU. They can however be safely identified by the OpenTelekomCloud Chassis asset tag. OpenTelekomCloud does use the network OpenStack DataSource, so we better detect it. LP: #1756471
2018-03-19Add Hetzner Cloud DataSourceScott Moser
The Hetzner Cloud metadata service is an AWS-style service available over HTTP via the link local address 169.254.169.254. https://hetzner.com/cloud https://docs.hetzner.cloud/
2018-02-21OVF: Fix VMware support for 64-bit platforms.Sankar Tanguturi
On few 64-bit platforms, the open-vm-tools package is installed at /usr/lib64/. The DataSourceOVF is changed to search look there for the 'customization plugin'
2018-02-21ds-identify: Fix searching for iso9660 OVF cdroms.Scott Moser
This fixes a bug in parsing of 'blkid -o export' output. The result of the bug meant that DI_ISO9660_DEVS did not get set correctly and is_cdrom_ovf would not identify devices in most cases. The tests are improved to demonstrate both multiple iso devices and also a cdrom that doesn't sort "last" in blkid output. The code change is to use DEVNAME as the record separator when parsing blkid -o export rather than relying on being able to read the empty line. LP: #1749980
2018-02-12ds-identify: check /writable/system-data/ for nocloud seed.Scott Moser
Ubuntu core seeds information to nocloud via a bind-mount of /writable/system-data/var/lib/cloud over /var/lib/cloud. When ds-identify runs as a systemd generator that mount is not guaranteed to have been done. It is guaranteed at cloud-init-local.service time, but not generator time. Images built with 'ubuntu-image --cloud-init=user-data-file' would have cloud-init disabled. The fix here is just to consider the seed dir under /writable/system-data. LP: #1747070
2018-01-26OVF: Extend well-known labels to include OVFENV.Scott Moser
Fujitsu Cloud Service attaches a ovf iso transport with a label 'OVFENV'. This seems to be a reasonable value as a label. While the for bug 1731868 would likely fix cloud-init on fujitsu cloud, this change will find it faster. LP: #1698669
2018-01-23Recognize uppercase vfat disk labelsJames Penick
New mkfs.vfat and fatlabel tools included in the dosfsutils package no longer support creating vfat disks with lowercase labels. They silently default to an all uppercase label eg CONFIG-2 instead of config-2. This change makes cloud-init handle either upper or lower case. LP: #1598783
2017-12-12ds-identify: failure in NoCloud due to unset variable usage.Scott Moser
The previous OVF datasource change added a debug message that referenced an un-used variable. The failure path would be triggered if an image was booted with a iso9660 filesystem attached to a device that was not a cdrom. A unit test is added for the specific failure found. Additional safety to avoid 'cidata' labels is also added to the OVF checker. LP: #1737704
2017-12-08OVF: improve ds-identify to support finding OVF iso transport.Scott Moser
Previously the OVF transport would not be identified except for when config files set 'ovf_vmware_guest_customization'. It would also return DS_MAYBE almost always. The change here is to add support to ds-identify for storing the iso9660 filesystems that it finds (ISO9660_DEVS). Then the OVF check will check that the iso9660 filesystem has ovf-env.xml on it. The least wonderful part of this is that the check is done by 'grep' for case insensitive ovf-env.xml. Future improvement would be to identify VMware's OVF by label or UUID so we could avoid the grep. LP: #1731868
2017-12-05Datasources: Formalize DataSource get_data and related properties.Chad Smith
Each DataSource subclass must define its own get_data method. This branch formalizes our DataSource class to require that subclasses define an explicit dsname for sourcing cloud-config datasource configuration. Subclasses must also override the _get_data method or a NotImplementedError is raised. The branch also writes /run/cloud-init/instance-data.json. This file contains all meta-data, user-data and vendor-data and a standardized set of metadata keys in a json blob which other utilities with root-access could make use of. Because some meta-data or user-data is potentially sensitive the file is only readable by root. Generally most metadata content types should be json serializable. If specific keys or values are not serializable, those specific values will be base64encoded and the key path will be listed under the top-level key 'base64-encoded-keys' in instance-data.json. If json writing fails due to other TypeErrors or UnicodeDecodeErrors, a warning log will be emitted to /var/log/cloud-init.log and no instance-data.json will be created.
2017-09-19tests: fix ds-identify unit tests to set EC2_STRICT_ID_DEFAULT.Scott Moser
The variable DI_EC2_STRICT_ID_DEFAULT was not being set in unit tests so when 16.04 built, which changed that setting in patches the tests would unexpectedly fail.
2017-09-07ds-identify: Make OpenStack return maybe on arch other than intel.Scott Moser
OpenStack Nova identifies itself only to Intel guests. Make ds-identify return 'MAYBE' for OpenStack on non-intel arches. An unnecessary change here is to rename the 'policy_nodmi' kwarg to 'policy_no_dmi' in the related unit tests. LP: #1715241
2017-09-05relocate tests/unittests/helpers.py to cloudinit/testsLars Kellogg-Stedman
This moves the base test case classes into into cloudinit/tests and updates all the corresponding imports.
2017-06-01azure: identify platform by well known value in chassis asset tag.Chad Smith
Azure sets a known chassis asset tag to 7783-7084-3265-9085-8269-3286-77. We can inspect this in both ds-identify and DataSource.get_data to determine whether we are on Azure. Added unit tests to cover these changes and some minor tweaks to Exception error message content to give more context on malformed or missing ovf-env.xml files. LP: #1693939
2017-05-30AliYun: Enable platform identification and enable by default.Junjie Wang
AliYun cloud platform is now identifying themselves by setting the dmi product id to the well known value "Alibaba Cloud ECS". The changes here identify that properly in tools/ds-identify and in the DataSourceAliYun. Since the 'get_data' for AliYun now identifies itself correctly, we can enable AliYun by default. LP: #1638931
2017-05-24test: update docstring on test_configured_list_with_noneScott Moser
Simply improve the docstring on a test added in last commit.
2017-05-24fix tools/ds-identify to not write None twice.Scott Moser
If the user configured: datasource_list: ["Ec2", "None"] then ds-identify would write datasource_list: ["Ec2", "None", "None"] which would break the logic to avoid warning.
2017-05-10Add unit tests for ds-identify, fix Ec2 bug found.Scott Moser
This adds several unit tests for ds-identify, and fixes a bug in Ec2 detection that I found while writing these tests. The method of testing is to use the ds-identify code as a shell library. The TestDsIdentify:call basically does: * populate a (temp) directory with files that represent what ds-identify would see in /sys or other locations it reads. * create a file '_shwrap' that replaces the 3 programs that are executed in ds-identify code path. It supports setting their stdout, stderr, and exit code. * set the default policies explicitly (DI_DEFAULT_POLICY) so we can support testing different builtins. This is necessary because the Ubuntu branches patch the builtin value. If we did not explicilty set it, then testing there would fail. * execute sh to source the script and call its main.
