2018-01-24Azure VM Preprovisioning support.Douglas Jordan
This change will enable azure vms to report provisioning has completed twice, first to tell the fabric it has completed then a second time to enable customer settings. The datasource for the second provisioning is the Instance Metadata Service (IMDS),and the VM will poll indefinitely for the new ovf-env.xml from IMDS. This branch introduces EphemeralDHCPv4 which encapsulates common logic used by both DataSourceEc2 an DataSourceAzure for temporary DHCP interactions without side-effects. LP: #1734991
2018-01-24btrfs: support resizing if root is mounted ro.Robert Schweikert
Resize of btrfs fails if the mount point for the file system we are trying to resize, i.e. the root of the filesystem is read only. With this change we use a known (currently snapper specific) rw location to work around a flaw that blocks resizing of the ro filesystem. LP: #1734787
2018-01-24OpenNebula: Improve network configuration support.Akihiko Ota
Network configuration in OpenNebula would only work if the host correctly guessed the names of the devices in the guest. OpenNebula provided data in its context.sh like 'ETH0_NETWORK', but if the guest named devices differently then results were not predictable. This would occur with Predictable Network Interface Names. To address this, newer versions (of OpenNebula provide the mac address ETH0_MAC. This function is present in 4.14 and documented officially in 5.0 docs. This provides support for reading the mac addresses from the context.sh. It also fixes cases where context.sh provided a field (ETH0_NETWORK or ETH0_MASK) with a empty string. Previously the empty string would be used rather than falling back to the default. LP: #1719157, #1716397, #1736750
2018-01-23tests: Fix attempted use of /run in a test case.Scott Moser
The previous commit added a test that would attempt to create and use /run/cloud-init/. This just modifies it to use a temp dir instead.
2018-01-23GCE: Improvements and changes to ssh key behavior for default user.Max Illfelder
The behavior changes and improvements include: - Only import keys into the default user that contain the name of the default user ('ubuntu', or 'centos') or that contain 'cloudinit'. - Use instance or project level keys based on GCE convention. - Respect expiration time when keys are set. Do not import expired keys. - Support ssh-keys in project level metadata (the GCE default). As part of this change, we also update the request header when talking to the metadata server based on the documentation: https://cloud.google.com/compute/docs/storing-retrieving-metadata#querying LP: #1670456, #1707033, #1707037, #1707039
2018-01-23subp: make ProcessExecutionError have expected types in stderr, stdout.Scott Moser
When subp raised a ProcessExecutionError, that exception's stderr and stdout might end up being the string '-' rather than bytes. This mean that:    try:        subp(mycommand, decode=False)    except ProcessExecutionError as e:        pass Would have 'e.stdout' set to '-' while the caller would expect bytes. Also reduce the try/except block in subp to a specifically the two lines that may raise an OSError.
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
2018-01-12Do not log warning on config files that represent None.Scott Moser
This issue was first identified when manual_cache_clean was set, as ds-identify would write /run/cloud-init/cloud.cfg with # manual_cache_clean that would generate a warning as cloud-init expected to load a dict. Any other "empty" config would also log such a warning. Also fix reading of di_report to allow it to be None, as ds-identify would write: di_report: # manual_cache_clean which reads as 'di_report: None' rather than di_report: {}. LP: #1742479
2018-01-10MAAS: add check_instance_id based off oauth tokens.Scott Moser
This stores a hash of the OAuth tokens as an 'id' for the maas datasource. Since new instances get new tokens created and those tokens are written by curtin into datasource system config this will provide a way to identify a new "instance" (install). LP: #1712680
2017-12-20SUSE: Add a basic test of network config rendering.Robert Schweikert
This simply increases test coverage in rendering of network config for SUSE and SLES.
2017-12-20Azure: Only bounce network when necessary.Chad Smith
This fixes a traceback when attempting to bounce the network after hostname resets. In artful and bionic ifupdown package is no longer installed in default cloud images. As such, Azure can't use those tools to bounce the network informing DDNS about hostname changes. This doesn't affect DDNS updates though because systemd-networkd is now watching hostname deltas and with default behavior to SendHostname=True over dhcp for all hostname updates which publishes DDNS for us. LP: #1722668
2017-12-14cli: Fix error in cloud-init modules --mode=init.Chad Smith
The cli help docs and argument parser allow the 'init' mode value which caused a traceback. Fix the cli to support 'init', 'config' and 'final' modes for the cloud-init modules subcommand. Add a check in the cli to raise a ValueError if a new subcommand ends up allowing an unsupported/unimplemented modes. Drive by unit test additions for a bit better coverage of error handling. LP: #1736600
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
2017-12-11ec2: Use instance-identity doc for region and instance-idAndrew Jorgensen
The instance identity document is a better source for region information, partly because region isn't actually in meta-data at all, only availability-zone, which happens to be named similarly.

2017-12-11tests: remove leaked tmp files in config drive tests.Scott Moser
Make sure that some temporary files used by the config drive tests get cleaned up properly.
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
2017-12-08VMware: Support for user provided pre and post-customization scriptsMaitreyee Saikia
In the VMware customization workflow, we have some options for the user to upload scripts for additional customization. Based on user request, those custom scripts can be either run before regular customization or after. For post customization scripts, we decide whether to run the scripts just after customization or post system reboot.
2017-12-07pylint: Update pylint to 1.7.1, run on tests/ and tools and fix complaints.Ryan Harper
The motivation for this is that a.) 1.7.1 runs with python 3.6 (bionic) b.) we want to run pylint on tests/ and tools for the same reasons that we want to run it on cloudinit/ The changes are described below. - Update tox.ini to invoke pylint v1.7.1. - Modify .pylintrc generated-members ignore mocked object members (m_.*) - Replace "dangerous" params defaulting to {} - Fix up cloud_tests use of platforms - Cast some instance objects to with dict() - Handle python2.7 vs 3+ ConfigParser use of readfp (deprecated) - Update use of assertEqual(<boolean>, value) to assert<Boolean>(value) - replace depricated assertRegexp -> assertRegex - Remove useless test-class calls to super class - Assign class property accessors a result and use it - Fix missing class member in CepkoResultTests - Fix Cheetah test import
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.
2017-12-05cli: Add clean and status subcommandsChad Smith
The 'cloud-init clean' command allows a user or script to clear cloud-init artifacts from the system so that cloud-init sees the system as unconfigured upon reboot. Optional parameters can be provided to remove cloud-init logs and reboot after clean. The 'cloud-init status' command allows the user or script to check whether cloud-init has finished all configuration stages and whether errors occurred. An optional --wait argument will poll on a 0.25 second interval until cloud-init configuration is complete. The benefit here is scripts can block on cloud-init completion before performing post-config tasks.
2017-11-30ec2: Fix sandboxed dhclient background process cleanup.Chad Smith
There is a race condition where our sandboxed dhclient properly writes a lease file but has not yet written a pid file. If the sandbox temporary directory is torn down before the dhclient subprocess writes a pidfile DataSourceEc2Local gets a traceback and the instance will fallback to DataSourceEc2 in the init-network stage. This wastes boot cycles we'd rather not spend. Fix handling of sandboxed dhclient to wait for both pidfile and leasefile before proceding. If either file doesn't show in 5 seconds, log a warning and return empty lease results {}. LP: #1735331
2017-11-21sysconfig: Correctly render dns and dns search info.Ryan McCabe
Currently when dns and dns search info is provided, it is not rendered when outputting to sysconfig format. This patch causes the DNS and DOMAIN lines to be written out rendering sysconfig. LP: #1705804
2017-11-20EC2: Fix bug using fallback_nic and metadata when restoring from cache.Scott Moser
If user upgraded to new cloud-init and attempted to run 'cloud-init init' without rebooting, cloud-init restores the datasource object from pickle. The older version pickled datasource object had no value for _network_config or fallback_nic. This caused the Ec2 datasource to attempt to reconfigure networking with a None fallback_nic. The pickled object also cached an older version of ec2 metadata which didn't contain network information. This branch does two things: - Add a fallback_interface property to DatasourceEC2 to support reading the old .fallback_nic attribute if it was set. New versions will call net.find_fallback_nic() if there has not been one found. - Re-crawl metadata if we are on Ec2 and don't have a 'network' key in metadata LP: #1732917

The etc/hosts file is was not properly setup for openSUSE or SLES when manage_etc_hosts is set in the config file. Improve the doc to address the fact that the 'localhost' ip is distribution dependent (not always 127.0.0.1). LP: #1731022
2017-11-10rh_subscription: Perform null checks for enabled and disabled repos.Dave Mulford
The rh_subscription module doesn't perform null checks when attempting to iterate on the enabled and disable repos arrays. When only one is specified, cloud-init fails to run.
2017-10-31EC2: Limit network config to fallback nic, fix local-ipv4 only instances.Chad Smith

2017-10-23resizefs: Fix regression when system booted with root=PARTUUID=Chad Smith
A recent cleanup of the resizefs module broke resizing when a system was booted with root=PARTUUID=<uuid> and the device /dev/root does not exist. This path is exposed with the Ubuntu 16.04 but not with Ubuntu 17.10. A recreate exists under bug 1684869. LP: #1725067
2017-10-20citest: fix remaining warnings raised by integration tests.Scott Moser
There was fallout in a full integration test run from my adding of test_no_warnings_in_log which asserted that there could not be a WARNING found in the /var/log/cloud-init.log This fixes 2 of the cases: * TestCommandOutputSimple had a valid WARNING written, so adjust its test case to allow for that. * TestLxdDir had a valid config in the test but the module would log a WARNING, so fix the module. Also updates lxd unit tests to look for WARN themselves.
2017-10-20ntp: fix config module schema to allow empty ntp configChad Smith
Fix three things related to the ntp module: 1. Fix invalid cloud-config schema in the integration test which provided empty dicts instead of emptylists for pools and servers 2. Correct logic in the ntp module to allow support for the minimal cloud-config 'ntp:' without raising a RuntimeError. Docs and schema definitions already describe that cloud-config's ntp can be empty. An ntp configuration with neither pools nor servers will be configured with a default set of ntp pools. As such, the ntp module now officially allows the following ntp cloud-configs: - ntp: - ntp: {} - ntp: servers: [] pools: [] 3. Add a simple unit test which validates all cloud-config provided to our integration tests to ensure it adheres to any defined module schema so as more jsonschema definitions are added, we validate our integration test configs. LP: #1724951
2017-10-05net: Handle bridge stp values of 0 and convert to boolean typeChad Smith
Update unit tests to pass a 0 instead of 'off' to validate that network state is properly written.
2017-10-05network: bridge_stp value not always correctRyan Harper
Update network_state to store the bridge_stp value as a boolean. The various renderers then can map the boolean value to the correct output as needed; eni uses 'on/off', sysconfig uses 'yes/no' and netplan will use the boolean directly. Update unittest values for sysconfig and netplan. Both contained the network_state string value which resulted in not correctly enable/disable STP in the target system. Update network_state comment (fd -> forward-delay, add stp as boolean) on bridge commands to match the expected format of a netplan bridge command. LP: #1721157

The change here supports reading these files in /run/systemd/netif/leases. The files declare that "This is private data. Do not parse.", but at this point we do not have another option. LP: #1718029

2017-09-22DataSourceOVF: use util.find_devs_with(TYPE=iso9660)Ryan Harper
DataSourceOVF attempts to find iso files via walking os.listdir('/dev/') which is far too wide. This approach is too invasive and can sometimes race with systemd attempting to fsck and mount devices. Instead, utilize cloudinit.util.find_devs_with to filter devices by criteria (which uses blkid under the covers). This results in fewer attempts to mount block devices which do not contain iso filesystems. Unittest changes include: - cloudinit.tests.helpers; introduce add_patch() helper - Add unittest coverage for DataSourceOVF use of transport_iso9660 LP: #1718287
2017-09-21tests: remove a temp file used in bootcmd tests.Scott Moser

2017-09-20docs: fix sphinx module schema documentationChad Smith
Create a copy of each modules schema attribute when generating sphinx docs to avoid altering the actual module dict in memory. This avoids illegible rendering of module examples and distros where each character of a list was represented on a separate line by itself. Fixes ntp, resizefs, runcmd and bootcmd docs.
2017-09-19tests: fix ds-identify unit tests to set EC2_STRICT_ID_DEFAULT.Scott Moser

2017-09-18GCE: Fix usage of user-data.Scott Moser
This regressed in the rework of GCE datasource to have a main. The fix really just stores the user-data that was read in self.userdata_raw, rather than self.userdata. That is consistent with other datasources and ulitimately how it was before the refactor. The main is updated to address the fact that user-data is binary data and may not be able to be printed. LP: #1717598
2017-09-15cmdline: add collect-logs subcommand.Chad Smith
Add a new collect-logs sub command to the cloud-init CLI. This script will collect all logs pertinent to a cloud-init run and store them in a compressed tar-gzipped file. This tarfile can be attached to any cloud-init bug filed in order to aid in bug triage and resolution. A cloudinit.apport module is also added that allows apport interaction. Here is an example bug filed via ubuntu-bug cloud-init: LP: #1716975. Once the apport launcher is packaged in cloud-init, bugs can be filed against cloud-init with the following command: ubuntu-bug cloud-init LP: #1607345
2017-09-15CloudStack: consider dhclient lease files named with a hyphen.Scott Moser
A regression in 'get_latest_lease' made it ignore files starting with 'dhclient-' rather than just 'dhclient.'. The fix here is to allow those files to be considered. There is a lot more we could do here to better ensure that we pick the most recent lease, but this change fixes the regression. LP: #1717147
2017-09-15resizefs: Drop check for read-only device file, do not warn on overlayroot.Chad Smith

2017-09-13cloud-config modules: honor distros definitions in each moduleChad Smith
Modules can optionally define a list of supported distros on which they can run by declaring a distros attribute in the cc_*py module. This branch fixes handling of cloudinit.stages.Modules.run_section. The behavior of run_section is now the following: - always run a module if the module doesn't declare a distros attribute - always run a module if the module declares distros = [ALL_DISTROS] - skip a module if the distribution on which we run isn't in module.distros - force a run of a skipped module if unverified_modules configuration contains the module name LP: #1715738 LP: #1715690

2017-09-13schema and docs: Add jsonschema to resizefs and bootcmd modulesChad Smith
Add schema definitions to both cc_resizefs and cc_bootcmd modules. Extend schema.py to parse and document enumerated json types. Schema definitions are used to generate module documention and log warnings for schema infractions. This branch also does the following: - drops vestigial 'resize_rootfs_tmp' option from cc_resizefs. That option only created the specified directory and didn't make use of that directory for any resize operations. - Drop yaml.dumps calls from schema documentation generation to avoid yaml import costs on module load - Add __doc__ = get_schema_doc(schema) definitions it each module to supplement python help() calls for cc_runcmd, cc_bootcmd, cc_ntp and cc_resizefs - Add a SCHEMA_EXAMPLES_SPACER_TEMPLATE string to docs for modules which contain more than one example
2017-09-07vmware customization: return network config formatSankar Tanguturi
For customizing the machines hosted on 'VMWare' hypervisor, the datasource should return the 'network config' data in 'curtin' format. This branch also fixes /etc/network/interfaces replacing the line "source /etc/network/interfaces.d/*.cfg" which is incorrectly removed when VMWare's Perl Customization Engine writes /etc/network/interfaces. Modify the code to read the customization configuration and return the converted data. Added few tests. LP: #1675063
2017-09-07Ec2: only attempt to operate at local mode on known platforms.Scott Moser
This change makes the DataSourceEc2Local do nothing unless it is on actual AWS platform. The motivation is twofold: a.) It is generally safer to only make this function available to Ec2 clones that explicitly identify themselves to the guest. (It also gives them a reason to supply identification code to cloud-init.) b.) On non-intel OpenStack platforms ds-identify would enable both the Ec2 and OpenStack sources. That is because there is not good data (such as dmi) to positively identify the platform. Previously that would be fine as OpenStack would run first and be successful. The change to add Ec2Local meant that an Ec2 now runs first. The best case for 'b' would be a slow down as attempts at the Ec2 metadata service time out. The discovered case was worse. Additionally we add a simple check for datatype of 'network' in the metadata before attempting to read it. LP: #1715128
2017-09-07Use /run/cloud-init for tempfile operations.Scott Moser
During boot, the usage of /tmp is not safe. In systemd systems, systemd-tmpfiles-clean may run at any point and clear out a temp file while cloud-init is using it. The solution here is to use /run/cloud-init/tmp. LP: #1707222
