dhclient-hook: cleanups, tests and fix a bug on 'down' event.

2018-12-03T22:07:59+00:00

I noticed a bug in dhclient_hook on the 'down' event, using 'is' operator rather than '==' (if self.net_action is 'down'). This refactors/simplifies the code a bit for easier testing and adds tests. The reason for the rename of 'action' to 'event' is to just be internally consistent. The word and Namespace 'action' is used by cloud-init main, so it was not really usable here. Also adds a main which can easily be debugged with: CI_DHCP_HOOK_DATA_D=./my.d python -m cloudinit.dhclient_hook up eth0

azure: retry imds polling on requests.Timeout

2018-11-13T03:14:58+00:00

There is an infrequent race when the booting instance can hit the IMDS service before it is fully available. This results in a requests.ConnectTimeout being raised. Azure's retry_callback logic now retries on either 404s or Timeouts. LP:1800223

update detection of openSUSE variants

2018-10-22T19:31:51+00:00

openSUSE has changed the way the distribution is identified in os-release. Add support detecting for openSUSE Leap 42.3, Leap 15 and TumbleWeed. Reference: boo#1111427

instance-data: Add standard keys platform and subplatform. Refactor ec2.

2018-10-09T21:46:35+00:00

Add the following instance-data.json standardized keys: * v1._beta_keys: List any v1 keys in beta development, e.g. ['subplatform']. * v1.public_ssh_keys: List of any cloud-provided ssh keys for the instance. * v1.platform: String representing the cloud platform api supporting the datasource. For example: 'ec2' for aws, aliyun and brightbox cloud names. * v1.subplatform: String with more details about the source of the metadata consumed. For example, metadata uri, config drive device path or seed directory. To support the new platform and subplatform standardized instance-data, DataSource and its subclasses grew platform and subplatform attributes. The platform attribute defaults to the lowercase string datasource name at self.dsname. This method is overridden in NoCloud, Ec2 and ConfigDrive datasources. The subplatform attribute calls a _get_subplatform method which will return a string containing a simple slug for subplatform type such as metadata, seed-dir or config-drive followed by a detailed uri, device or directory path where the datasource consumed its configuration. As part of this work, DatasourceEC2 methods _get_data and _crawl_metadata have been refactored for a few reasons: - crawl_metadata is now a read-only operation, persisting no attributes on the datasource instance and returns a dictionary of consumed metadata. - crawl_metadata now closely represents the raw stucture of the ec2 metadata consumed, so that end-users can leverage public ec2 metadata documentation where possible. - crawl_metadata adds a '_metadata_api_version' key to the crawled ds.metadata to advertise what version of EC2's api was consumed by cloud-init. - _get_data now does all the processing of crawl_metadata and saves datasource instance attributes userdata_raw, metadata etc. Additional drive-bys: * unit test rework for test_altcloud and test_azure to simplify mocks and make use of existing util and test_helpers functions.

user-data: jinja template to render instance-data.json in cloud-config

2018-09-11T17:31:46+00:00

Allow users to provide '## template: jinja' as the first line or their #cloud-config or custom script user-data parts. When this header exists, the cloud-config or script will be rendered as a jinja template. All instance metadata keys and values present in /run/cloud-init/instance-data.json will be available as jinja variables for the template. This means any cloud-config module or script can reference any standardized instance data in templates and scripts. Additionally, any standardized instance-data.json keys scoped below a '' key will be promoted as a top-level key for ease of reference in templates. This means that '{{ local_hostname }}' is the same as using the latest '{{ v#.local_hostname }}'. Since instance-data is written to /run/cloud-init/instance-data.json, make sure it is persisted across reboots when the cached datasource opject is reloaded. LP: #1791781

tests: print failed testname instead of docstring upon failure

2018-09-05T17:31:23+00:00

tests: Disallow use of util.subp except for where needed.

2018-09-05T16:02:25+00:00

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.

sysconfig: refactor sysconfig to accept distro specific templates paths

2018-09-05T14:17:16+00:00

Multiple distros use sysconfig format but have different content and paths to certain files. Update distros to specify these template paths in their renderer_configs dictionary.

Add unit tests for config/cc_ssh.py

2018-09-01T17:59:18+00:00

These tests focus on the apply_credentials method and the ssh setup for root and a distro default user.

Fix the built-in cloudinit/tests/helpers:skipIf

2018-08-31T22:13:09+00:00

this version uses unittest2 skipIf which is present in our python 2.6 environment.
