2017-08-31upstart: do not package upstart jobs, drop ubuntu-init-switch module.Scott Moser
The ubuntu-init-switch module allowed the use to launch an instance that was booted with upstart and have it switch its init system to systemd and then reboot itself. It was only useful for the time period when Ubuntu was transitioning to systemd but only produced images using upstart. Also, do not run setup with --init-system=upstart. This means that by default, debian packages built with packages/bddeb will not have upstart unit files included. No other removal is done here.
2017-08-25doc: Explain error behavior in user data include file format.Jason Butz
Update user data 'include file' format documentation to explain the behavior that occurs when an error occurs while reading a file.
2017-08-22schema cli: Add schema subcommand to cloud-init cli and cc_runcmd schemaChad Smith
This branch does a few things: - Add 'schema' subcommand to cloud-init CLI for validating cloud-config files against strict module jsonschema definitions - Add --annotate parameter to 'cloud-init schema' to annotate existing cloud-config file content with validation errors - Add jsonschema definition to cc_runcmd - Add unit test coverage for cc_runcmd - Update CLI capabilities documentation This branch only imports development (and analyze) subparsers when the specific subcommand is provided on the CLI to avoid adding costly unused file imports during cloud-init system boot. The schema command allows a person to quickly validate a cloud-config text file against cloud-init's known module schemas to avoid costly roundtrips deploying instances in their cloud of choice. As of this branch, only cc_ntp and cc_runcmd cloud-config modules define schemas. Schema validation will ignore all undefined config keys until all modules define a strict schema. To perform validation of runcmd and ntp sections of a cloud-config file: $ cat > cloud.cfg <<EOF runcmd: bogus EOF $ python -m cloudinit.cmd.main schema --config-file cloud.cfg $ python -m cloudinit.cmd.main schema --config-file cloud.cfg \ --annotate Once jsonschema is defined for all ~55 cc modules, we will move this schema subcommand up as a proper subcommand of the cloud-init CLI.
2017-08-21tools: Add tooling for basic cloud-init performance analysis.Chad Smith
This branch adds cloudinit-analyze into cloud-init proper. It adds an "analyze" subcommand to the cloud-init command line utility for quick performance assessment of cloud-init stages and events. On a cloud-init configured instance, running "cloud-init analyze blame" will now report which cloud-init events cost the most wall time. This allows for quick assessment of the most costly stages of cloud-init. This functionality is pulled from Ryan Harper's analyze work. The cloudinit-analyze main script itself has been refactored a bit for inclusion as a subcommand of cloud-init CLI. There will be a followup branch at some point which will optionally instrument detailed strace profiling, but that approach needs a bit more discussion first. This branch also adds: * additional debugging topic to the sphinx-generated docs describing cloud-init analyze, dump and show as well as cloud-init single usage. * Updates the Makefile unittests target to include cloudinit directory because we now have unittests within that package. LP: #1709761

2017-07-17doc: fix disk setup example table_type optionsSandor Zeestraten
This fixes the disk setup example doc which specifies that the only currently supported table_type option is 'mbr' by adding the 'gpt' option which got supported as of 0.7.7. LP: #1703789
2017-07-11doc: document the cmdline options to NoCloudBrian Candler
Add permitted keys to documentation on seeding NoCloud.
2017-06-15docs: Automatically generate module docs form schema if present.Chad Smith
We have started adding jsonschema definitions for cloudconfig modules (cc_ntp). This branch allows us render sphinx docs using the module's shema definition instead of using the module's docstring. This allows us to avoid duplicating schema documentation in the module-level docstring and schema definition. The corresponding module documentation is extended a bit to differentiate between config schema and potential examples.
2017-06-08Integration Testing: tox env, pyxld 2.2.3, and revamp frameworkWesley Wiedenmeier
Massive update to clean up and greatly enhance the integration testing framework developed by Wesley Wiedenmeier. - Updated tox environment to run integration test 'citest' to utilize pylxd 2.2.3 - Add support for distro feature flags - add framework for feature flags to release config with feature groups and overrides allowed in any release conf override level - add support for feature flags in platform and config handling - during collect, skip testcases that require features not supported by the image with a warning message - Enable additional distros (i.e. centos, debian) - Add 'bddeb' command to build a deb from the current working tree cleanly in a container, so deps do not have to be installed on host - Adds a command line option '--preserve-data' that ensures that collected data will be left after tests run. This also allows the directory to store collected data in during the run command to be specified using '--data-dir'. - Updated Read the Docs testing page and doc strings for pep 257 compliance
2017-06-08Chef: Update omnibus url to chef.io, minor doc changes.JJ Asghar
- Updated to standard chef.io url - Removed the port 4000, due to that has been deprecated - Added Note about the run_list not being required Signed-off-by: JJ Asghar <jj@chef.io>
2017-06-06NoCloud: support seed of nocloud from smbios informationVladimir Pouzanov
This allows the user to seed NoCloud in a trivial way from qemu/libvirt, by using a stock image and passing a single command line flag. No custom command line, no filesystem modification, no bootstrap disk image. This is particularly handy now that Ec2 backend is discouraged from use under bug 1660385. LP: #1691772

2017-05-03fs_setup: if cmd is specified, use shell interpretation.Paul Meyer
If 'cmd' is provided to a fs_setup entry, then cloud-init was trying to execute the rendered string as a single name, rather than splitting the string. The change here will pass the string to shell for interpretation so that it is split there. Also fix some documentation errors and warn when fs_opts or overwrite is provided along with 'cmd'. LP: #1687712
2017-05-03doc: document network configuration defaults policy and formats.Ryan Harper
Add documentation for cloud-init networking configuration formats, default behavior, policy and other specific details about how network config is consumed and utilized.
2017-04-21Doc: add additional RTD examplesJoshua Powers
Includes missing examples for RTD, including examples for datasources, disk partitions and apt update. Also fix doc in cloud-config-update-apt.txt. LP: #1459604
2017-04-12doc: Fix example for resolve.conf configuration.Jon Grimm
Should be 'manage_resolv_conf' not 'manage-resolv-conf'. LP: #1531582
2017-04-12Fix examples that reference upstream chef repository.Jon Grimm
Also add integration test. Note: this new test is not comprehensive; it simply ensures that the example chef configuration does not blow up and that chef seems to be installed after its completion. This new test is disabled by default as it depends on a 3rd party repository. LP: #1678145
2017-04-12doc: correct grammar and improve clarity in merging documentation.David Tagatac
Move merging.rst into doc/rtd/topics with small fixes.

2017-03-24Add support for setting hashed passwordsTore S. Lonoy
This change will add support for hashed passwords in cc_set_passwords. It checks if a password is a hash with by checking that it matches in fairly safe way, and also that the password does not have a ":" in it. chpasswd needs to know if the password is hashed or not, so two lists is created so chpasswd is feed with the correct one. LP: #1570325
2017-03-17doc: fix config drive doc with regard to unpartitioned disks.Scott Moser
The ConfigDrive datasource has read un-partitioned disks for quite a while, but the documentation lagged behind. LP: #1673818
2017-03-13doc: add instructions for running integration tests via tox.Joshua Powers
Add instructions on how to run the cii tests to the docs.
2017-03-10Add feature flags to cloudinit.version.Wesley Wiedenmeier
This exposes a mechanism for users of cloud-init to determine if a version has a specific feature, and adds documentation to that affect. We list an existing feature NETWORK_CONFIG_V1 as an example. Also add a 'features' subcommand for listing these to stdout.
2017-01-26Fix small typo and change iso-filename for consistencyRobin Naundorf
* Fix small typo * Fix ISO-Filename for consistency
2017-01-17doc: Fix typos and clarify some aspects of the part-handlerErik M. Bray
The existing documentation referred to a handle_type method when it really should be handle_part. It also referred to 'methods' when it really should say 'functions' to be clear (while it's true the built-in handlers are classes with methods of these names, in this context we mean module-level functions). Also clarified that a part-handler should come before the parts that it handles, and can override built-in handlers.
2017-01-17doc: add some documentation on OpenStack datasource.Scott Moser
This just fills out some of the documentation on the OpenStack datasource.

2016-12-23doc: adjust headers in tests documentation for consistency.Scott Moser
This just makes headers in doc/rtd/topics/tests.rst consistent with other rst files, as the comment in doc/rtd/index.rst suggests.
2016-12-22integration test: initial commit of integration test frameworkWesley Wiedenmeier
The adds in end-to-end testing of cloud-init. The framework utilizes LXD and cloud images as a backend to test user-data passed in. Arbitrary data is then captured from predefined commands specified by the user. After collection, data verification is completed by running a series of Python unit tests against the collected data. Currently only the Ubuntu Trusty, Xenial, Yakkety, and Zesty releases are supported. Test cases for 50% of the modules is complete and available. Additionally a Read the Docs file was created to guide test writing and execution.
2016-12-19doc: change 'nobootwait' to 'nofail' in docsAnhad Jai Singh
'nobootwait' is an upstart specific extension to the mount syntax that is not supported by other mount systems. As Ubuntu 16.04 moved from upstart to systemd, support for 'nobootwait' was lost. All examples using 'nobootwait' are updated to use the standard 'nofail', which gives the expected behaviour of not failing to boot in case a volume is missing. There are subtle differences in semantics between 'nobootwait' and 'nofail', but it is the best substitute that gives behaviour similar to the upstart specific option.
2016-12-02fix decoding of utf-8 chars in yaml testScott Moser
Python 3 would fail to load yaml from doc/examples/cloud-config-apt.txt when the LANG (specifically LC_CTYPE) was 'C'. The changes here do 2 things: a.) remove the non-ascii characters from the yaml file. b.) fix the validate-yaml.py program to decode using utf-8 specifically rather than using the inherited settings. This fixes it now for ascii and in the future also should non-ascii slip in.
2016-11-22Doc: various documentation fixesSean Bright
Several various minor fixes for the readthedocs documentation.
2016-11-10doc: Add documentation on stages of boot.Scott Moser
This adds long overdue documentation on stages that cloud-init runs during boot.
2016-11-10doc: make the RST files consistently formated and other improvements.Scott Moser
The biggest things here are: * move doc/sources/*/README.rst to doc/rtd/topics/datasources This gives each datasource a page in the rtd docs, which make it easier to read. * consistently use the same header style throughout. As suggested at http://thomas-cokelaer.info/tutorials/sphinx/rest_syntax.html use: # with overline, for parts * with overline, for chapters =, for sections -, for subsections ^, for subsubsections “, for paragraphs Also, move and re-format vendor-data documentation to rtd.
2016-11-08doc: fixed example to not overwrite /etc/hostsChris Glass
Instead, it will simply append the new entry.
2016-10-20Add documentation for logging features.Wesley Wiedenmeier
Update the summary of rsyslog module and add logging.rst to docs.
2016-10-20Add support for snap create-user on Ubuntu Core images.Ryan Harper
Ubuntu Core images use the `snap create-user` to add users to an Ubuntu Core system. Add support for creating snap users by adding a key to the users dictionary. users: - name: bob snapuser: bob@bobcom.io Or via the 'snappy' dictionary: snappy: email: bob@bobcom.io Users may also create a snap user without contacting the SSO by providing a 'system-user' assertion by importing them into snapd. Additionally, Ubuntu Core systems have a read-only /etc/passwd such that the normal useradd/groupadd commands do not function without an additional flag, '--extrausers', which redirects the pwd to /var/lib/extrausers. Move the system_is_snappy() check from cc_snappy module to util for re-use and then update the Distro class to append '--extrausers' if the system is Ubuntu Core.
2016-09-30Improve module documentation and doc cleanup.Wesley Wiedenmeier
This adds lots of config module documentation in a standard format. It will greatly improve the content at readthedocs. Additionally: * Add a 'doc' env to tox.ini * Changed default highlight language for sphinx conf from python to yaml most examples in documentation are yaml configs * Updated datasource examples to highlight sh code properly
2016-08-22azure dhclient-hook cleanupsScott Moser
This adds some function to the generator to maintain the presense of a flag file '/run/cloud-init/enabled' indicating that cloud-init is enabled. Then, only run the dhclient hooks if on Azure and cloud-init is enabled. The test for is_azure currently only checks to see that the board vendor is Microsoft, not actually that we are on azure. Running should not be harmful anywhere, other than slowing down dhclient. The value of this additional code is that then dhclient having run does not task the system with the load of cloud-init. Additionally, some changes to config are done here. * rename 'dhclient_leases' to 'dhclient_lease_file' * move that to the datasource config (datasource/Azure/dhclient_lease_file) Also, it removes the config in config/cloud.cfg that set agent_command to __builtin__. This means that by default cloud-init still needs the agent installed. The suggested follow-on improvement is to use __builtin__ if there is no walinux-agent installed.
2016-08-18Apt: add new apt configuration formatChristian Ehrhardt
This adds an improved apt configuration format that is fully backwards compatible with previous behavior. This is mostly copied from curtin's implementation. It does: * clean up and centralizes many of the top level 'apt_*' values that previously existed into a single top level 'apt'key. * support a 'source' in apt/sources/entry that has only a key * documents new features and adds tests. See the added doc/examples/cloud-config-apt.txt for more information.
2016-08-15Get Azure endpoint server from DHCP clientBrent Baude
It is more efficient and cross-distribution safe to use the hooks function from dhclient to obtain the Azure endpoint server (DHCP option 245). This is done by providing shell scritps that are called by the hooks infrastructure of both dhclient and NetworkManager. The hooks then invoke 'cloud-init dhclient-hook' that maintains json data with the dhclient options in /run/cloud-init/dhclient.hooks/<interface>.json . The azure helper then pulls the value from /run/cloud-init/dhclient.hooks/<interface>.json file(s). If that file does not exist or the value is not present, it will then fall back to the original method of scraping the dhcp client lease file.
2016-08-10add ntp config moduleRyan Harper
Add support for installing and configuring ntp service, exposing the minimum config of servers or pools to be added. If none are defined then fallback on generating a list of pools by distro hosted at pool.ntp.org (which matches what's found in the default ntp.conf shipped in the respective distro).
2016-06-03tests: fix apt tests to run inside ubuntu build environmentScott Moser
This just mocks out use of lsb_release as it is not available in a build environment. Additionally mocks out use of getkeybyid. This admittedly makes the test for a long key fingerprint not useful as it was broken only inside getkeybyid. Also fix 'make yaml' for cloud-config.txt
2016-06-03Apt sources configuration improvementsScott Moser
- keyid-only (no source statement) - key only (no source statement) - custom source.list template - support long gpg key fingerprints with spaces - fix issue with key's that were already in the local gpg keyring - allowing a new format to specify apt_sources in a dictionary instead of a list to allow merging of configurations LP: #1574113
