Applied Black and isort, fixed any linting issues, updated tox.ini and CI.
2021-12-10sources/azure: remove unnecessary hostname bounce (#1143)Chris Patterson
Thanks to [1], the hostname is set prior to network bring-up. The Azure data source has been bouncing the hostname during setup(), occurring after the hostname has already been properly configured. Note that this doesn't prevent leaking the image's hostname during Azure's _get_data() when it brings up ephemeral DHCP. However, as are not guaranteed to have the hostname metadata available from a truly "local" source, this behavior is to be expected unless we disable `send host-name` from dhclient config.

2021-12-06Add Strict Metaschema Validation (#1101)Brett Holman
Improve schema validation. This adds strict validation of config module definitions at testing time, with plumbing included for future runtime validation. This eliminates a class of bugs resulting from schemas that have definitions that are incorrect, but get interpreted by jsonschema as "additionalProperties" that are therefore ignored. - Add strict meta-schema for jsonschema unit test validation - Separate schema from module metadata structure - Improve type annotations for various functions and data types Cleanup: - Remove unused jsonschema "required" elements - Eliminate manual memoization in schema.py:get_schema(), reference module.__doc__ directly
2021-12-03Reorganize unit test locations under tests/unittests (#1126)Brett Holman
This attempts to standardize unit test file location under test/unittests/ such that any source file located at cloudinit/path/to/file.py may have a corresponding unit test file at test/unittests/path/to/test_file.py. Noteworthy Comments: ==================== Four different duplicate test files existed: test_{gpg,util,cc_mounts,cc_resolv_conf}.py Each of these duplicate file pairs has been merged together. This is a break in git history for these files. The test suite appears to have a dependency on test order. Changing test order causes some tests to fail. This should be rectified, but for now some tests have been modified in tests/unittests/config/test_set_passwords.py. A helper class name starts with "Test" which causes pytest to try executing it as a test case, which then throws warnings "due to Class having __init__()". Silence by changing the name of the class. # helpers.py is imported in many test files, import paths change cloudinit/tests/helpers.py -> tests/unittests/helpers.py # Move directories: cloudinit/distros/tests -> tests/unittests/distros cloudinit/cmd/devel/tests -> tests/unittests/cmd/devel cloudinit/cmd/tests -> tests/unittests/cmd/ cloudinit/sources/helpers/tests -> tests/unittests/sources/helpers cloudinit/sources/tests -> tests/unittests/sources cloudinit/net/tests -> tests/unittests/net cloudinit/config/tests -> tests/unittests/config cloudinit/analyze/tests/ -> tests/unittests/analyze/ # Standardize tests already in tests/unittests/ test_datasource -> sources test_distros -> distros test_vmware -> sources/vmware test_handler -> config # this contains cloudconfig module tests test_runs -> runs
2021-12-02jinja: provide and document jinja-safe key aliases in instance-data (SC-622) ↵Chad Smith
(#1123) Allow #cloud-config and cloud-init query to use underscore-delimited "jinja-safe" key aliases for any instance-data.json keys containing jinja operator characters. This provides a means to use Jinja's dot-notation instead of square brackets and quoting to reference "unsafe" obtain attribute names. Support for these aliased keys is available to both #cloud-config user-data and `cloud-init query`. For example #cloud-config alias access can look like: {{ ds.config.user_network_config }} - instead of - {{ ds.config["user.network-config"] }}
2021-11-22docs: Rename HACKING.rst to CONTRIBUTING.rst (#1118)James Falcon
This is more consistent with other github repositories, and will prompt a first-time contributor to read the contributing guidelines before submitting the pull request. Additionally, added a summary section to the top, updated some outdated language, and removed some outdated typing guidance.
2021-11-01Add LXD datasource (#1040)Chad Smith
Add DataSourceLXD which knows how to talk to the dev-lxd socket to obtain all instance metadata API: https://linuxcontainers.org/lxd/docs/master/dev-lxd. This first branch is to deliver feature parity with the existing NoCloud datasource which is currently used to intialize LXC instances on first boot. Introduce a SocketConnectionPool and LXDSocketAdapter to support performing HTTP GETs on the following routes which are surfaced by the LXD host to all containers: http://unix.socket/1.0/meta-data http://unix.socket/1.0/config/user.user-data http://unix.socket/1.0/config/user.network-config http://unix.socket/1.0/config/user.vendor-data These 4 routes minimally replace the static content provided in the following nocloud-net seed files: /var/lib/cloud/nocloud-net/{meta-data,vendor-data,user-data,network-config} The intent of this commit is to set a foundation for LXD socket communication that will allow us to build network hot-plug features by eventually consuming LXD's websocket upgrade route 1.0/events to react to network, meta-data and user-data config changes over time. In the event that no custom network-config is provided, default to the same network-config definition provided by LXD to the NoCloud network-config seed file. Supplemental features above NoCloud datasource: surface all custom instance data config keys via cloud-init query ds which aids in discoverability of features/tags/labels as well as conditional #cloud-config jinja templates operations based on custom config options. TBD: better cloud-init query support for dot-delimited keys
2021-10-27Add "install hotplug" module (SC-476) (#1069)James Falcon
This commit removes automatically installing udev rules for hotplug and adds a module to install them instead. Automatically including the udev rules and checking if hotplug was enabled consumed too many resources in certain circumstances. Moving the rules to a module ensures we don't spend extra extra cycles on hotplug if hotplug functionality isn't desired. LP: #1946003
2021-10-07Allow disabling of network activation (SC-307) (#1048)James Falcon
In #919 (81299de), we refactored some of the code used to bring up networks across distros. Previously, the call to bring up network interfaces during 'init' stage unintentionally resulted in a no-op such that network interfaces were NEVER brought up by cloud-init, even if new network interfaces were found after crawling the metadata. The code was altered to bring up these discovered network interfaces. On ubuntu, this results in a 'netplan apply' call during 'init' stage for any ubuntu-based distro on a datasource that has a NETWORK dependency. On GCE, this additional 'netplan apply' conflicts with the google-guest-agent service, resulting in an instance that can no be connected to. This commit adds a 'disable_network_activation' option that can be enabled in /etc/cloud.cfg to disable the activation of network interfaces in 'init' stage. LP: #1938299
2021-10-07Support ETHx_IP6_GATEWAY, SET_HOSTNAME on OpenNebula (#1045)Vlastimil Holer
OpenNebula 6.1.80 (current dev. version) is introducing new IPv6 gateway contextualization variable ETHx_IP6_GATEWAY, which mimics existing variable ETHx_GATEWAY6. The ETHx_GATEWAY6 used until now will be depracated in future relase (ET spring 2022). See: - new variable - https://github.com/OpenNebula/one/commit/e4d2cc11b9f3c6d01b53774b831f48d9d089c1cc - deprecation tracking issue - https://github.com/OpenNebula/one/issues/5536 Also, added support for SET_HOSTNAME context variable, which is currently widely used variable to configure guest VM hostname. See https://docs.opennebula.io/6.0/management_and_operations/references/template.html#context-section

2021-08-09Datasource for VMware (#953)Andrew Kutz
This patch finally introduces the Cloud-Init Datasource for VMware GuestInfo as a part of cloud-init proper. This datasource has existed since 2018, and rapidly became the de facto datasource for developers working with Packer, Terraform, for projects like kube-image-builder, and the de jure datasource for Photon OS. The major change to the datasource from its previous incarnation is the name. Now named DatasourceVMware, this new version of the datasource will allow multiple transport types in addition to GuestInfo keys. This datasource includes several unique features developed to address real-world situations: * Support for reading any key (metadata, userdata, vendordata) both from the guestinfo table when running on a VM in vSphere as well as from an environment variable when running inside of a container, useful for rapid dev/test. * Allows booting with DHCP while still providing full participation in Cloud-Init instance data and Jinja queries. The netifaces library provides the ability to inspect the network after it is online, and the runtime network configuration is then merged into the existing metadata and persisted to disk. * Advertises the local_ipv4 and local_ipv6 addresses via guestinfo as well. This is useful as Guest Tools is not always able to identify what would be considered the local address. The primary author and current steward of this datasource spoke at Cloud-Init Con 2020 where there was interest in contributing this datasource to the Cloud-Init codebase. The datasource currently lives in its own GitHub repository at https://github.com/vmware/cloud-init-vmware-guestinfo. Once the datasource is merged into Cloud-Init, the old repository will be deprecated.

2021-07-23Add ability to manage fallback network config on PhotonOS (#941)sshedi
Currently cloud-init generates fallback network config on various scenarios. For example: 1. When no DS found 2. There is no 'network' info given in DS metadata. 3. If a DS gives a network config once and upon reboot if DS doesn't give any network info, previously set network data will be overridden. A newly introduced key in cloud.cfg.tmpl can be used to control this behavior on PhotonOS. Also, if OS comes with a set of default network files(configs), like in PhotonOS, cloud-init should not overwrite them by default. This change also includes some nitpicking changes of reorganizing few config variables. Signed-off-by: Shreenidhi Shedi <sshedi@vmware.com>
2021-07-19Document known hotplug limitations (#950)James Falcon
2021-07-19Initial hotplug support (#936)James Falcon
Adds a udev script which will invoke a hotplug hook script on all net add events. The script will write some udev arguments to a systemd FIFO socket (to ensure we have only instance of cloud-init running at a time), which is then read by a new service that calls a new 'cloud-init devel hotplug-hook' command to handle the new event. This hotplug-hook command will: - Fetch the pickled datsource - Verify that the hotplug event is supported/enabled - Update the metadata for the datasource - Ensure the hotplugged device exists within the datasource - Apply the config change on the datasource metadata - Bring up the new interface (or apply global network configuration) - Save the updated metadata back to the pickle cache Also scattered in some unrelated typing where helpful

2021-06-17Fix DNS in NetworkState (SC-133) (#923)James Falcon
v1 network config currently has no concept of interface-specific DNS, which is required for certain renderers. To fix this, added an optional 'interface' key on the v1 nameserver definition. If specified, it makes the DNS settings specific to the interface. Otherwise, it will be defined as global DNS as it always has. Additionally, DNS for v2 wasn't being recognized correctly. For DNS defined on a particular interface, these settings now also go into the global DNS settings as they were intended.

2021-06-14add DragonFlyBSD support (#904)Gonéri Le Bouder
- Mostly based on FreeBSD, the main exception is that `find_devs_with_on_freebsd` does not work. - Since we cannot get the CDROM or the partition labels, `find_devs_with_on_dragonflybsd()` has a more naive approach and returns all the block devices.

2021-05-13Allow user control over update events (#834)James Falcon
Control is currently limited to boot events, though this should allow us to more easily incorporate HOTPLUG support. Disabling 'instance-first-boot' is not supported as we apply networking config too early in boot to have processed userdata (along with the fact that this would be a pretty big foot-gun). The concept of update events on datasource has been split into supported update events and default update events. Defaults will be used if there is no user-defined update events, but user-defined events won't be supplied if they aren't supported. When applying the networking config, we now check to see if the event is supported by the datasource as well as if it is enabled. Configuration looks like: updates: network: when: ['boot']
2021-04-14doc: Replace remaining references to user-scripts as a config module (#866)Ryan Harper

2021-01-27[VMware] change default max wait time to 15s (#774)xiaofengw-vmware
If cloud-init is enabled on VMware platform, cloud-init will wait until its configuration file is ready and currently the max wait is 90 seconds by default. With our test, this configuration file should be ready within 1 second, so change it to 15 seconds for better performance. Also update the documentation about how to change the default value in cloud-init configuration file.

2020-12-03integration_tests: introduce skipping of tests by OS (#702)Daniel Watkins
This introduces an optional, more complex OS_IMAGE format (`<image id>::<os>::<release>`) which allows the specification of the OS/OS release which the given image ID corresponds to. This information is used to skip tests which do not apply to the image. This commit is comprised of the following discrete changes: * introduce the IntegrationImage class, to handle parsing and storing the new OS_IMAGE format * support inferring the OS and OS release of Ubuntu series, so that we can continue to set OS_IMAGE to just a series name and have test skipping work * add documentation on Image Selection to integration_tests.rst * introduce the actual skipping behaviour based on OS marks * apply the `ubuntu` mark to all tests that should be skipped on non-Ubuntu operating systems
