2020-06-08Move subp into its own module. (#416)Scott Moser
This was painful, but it finishes a TODO from cloudinit/subp.py. It moves the following from util to subp: ProcessExecutionError subp which target_path I moved subp_blob_in_tempfile into cc_chef, which is its only caller. That saved us from having to deal with it using write_file and temp_utils from subp (which does not import any cloudinit things now). It is arguable that 'target_path' could be moved to a 'path_utils' or something, but in order to use it from subp and also from utils, we had to get it out of utils.

This fixes issues with closing brackets not matching the opening bracket's line and continuation line under-idented for hanging indent.
2020-05-04bsd: upgrade support (#305)Gonéri Le Bouder
Implement the upgrade support: - FreeBSD: using `pkg upgrade` - NetBSD: with `pkgin`
2020-03-12Add Netbsd support (#62)Gonéri Le Bouder
Add support for the NetBSD Operating System. Features in this branch: * Add BSD distro parent class from which NetBSD and FreeBSD can specialize * Add *bsd util functions to cloudinit.net and cloudinit.net.bsd_utils * subclass cloudinit.distro.freebsd.Distro from bsd.Distro * Add new cloudinit.distro.netbsd and cloudinit.net.renderer for netbsd * Add lru_cached util.is_NetBSD functions * Add NetBSD detection for ConfigDrive and NoCloud datasources This branch has been tested with: - NoCloud and OpenStack (with and without config-drive) - NetBSD 8.1. and 9.0 - FreeBSD 11.2 and 12.1 - Python 3.7 only, because of the dependency oncrypt.METHOD_BLOWFISH. This version is available in NetBSD 7, 8 and 9 anyway
2020-02-03sysconfig: distro-specific config rendering for BOOTPROTO option (#162)Robert Schweikert
- Introduce the "flavor" configuration option for the sysconfig renderer this is necessary to account for differences in the handling of the BOOTPROTO setting between distributions (lp#1858808) + Thanks to Petr Pavlu for the idea - Network config clean up for sysconfig renderer + The introduction of the "flavor" renderer configuration allows us to only write values that are pertinent for the given distro - Set the DHCPv6 client mode on SUSE (lp#1800854) Co-authored-by: Chad Smith <chad.smith@canonical.com> LP: #1800854
2020-01-31cloudinit: replace "from six import X" imports (except in util.py) (#183)Daniel Watkins
2020-01-29Replace mock library with unittest.mock (#186)Daniel Watkins
* cloudinit: replace "import mock" with "from unittest import mock" * test-requirements.txt: drop mock Co-authored-by: Chad Smith <chad.smith@canonical.com>
2020-01-23cloudinit: remove ImportError handling for mock imports (#182)Daniel Watkins
We only run on Python 3 now, so we can unambiguously expect unittest.mock to exist.
2020-01-08net: fix rendering of 'static6' in network config (#77)Ryan Harper
* net: fix rendering of 'static6' in network config A V1 static6 network typo was misrendered in eni, it's not valid. It was ignored in sysconfig and netplan. This branch fixes eni, updates sysconfig, netplan to render it correctly and adds unittests for all cases. Reported-by: Raphaël Enrici LP: #1850988 * net: add comment about static6 type in subnet_is_ipv6 Co-authored-by: Chad Smith <blackboxsw@gmail.com> Co-authored-by: Daniel Watkins <daniel@daniel-watkins.co.uk>
2019-12-20freebsd: introduce the freebsd renderer (#61)Gonéri Le Bouder
* freebsd: introduce the freebsd renderer Refactoring of the FreeBSD code base to provide a real network renderer for FreeBSD. Use the generic update_sysconfig_file() from rhel_util to handle the access to /etc/rc.conf. Interfaces are not automatically renamed by FreeBSD using the following configuration in /etc/rc.conf: ``` ifconfig_fxp0_name="eth0" ``` * freesd: use regex named groups Reduce the complexity of `get_interfaces_by_mac_on_freebsd()` with named groups. * freebsd: breaks up _write_network() in tree small functions - `_write_ifconfig_entries()` - `_write_route_entries()` - `_write_resolve_conf()` * extend find_fallback_nic() to support FreeBSD this uses `route -n show default` to find the default interface * freebsd: use dns keys from NetworkState class The NetworkState class (settings instance) exposes the DNS configuration in two keys: - `dns_nameservers` - `dns_searchdomains` On OpenStack, these keys are set when a global DNS server is set. The alternative is the `dns_nameservers` and `dns_search` keys from each subdomain. We continue to read those. * freebsd: properly target the /etc/resolv.conf file * freebsd: ignore 'service routing restart' ret code On FreeBSD 10, the restart of routing and dhclient is likely to fail because - routing: it cannot remove the loopback route, but it will still set up the default route as expected. - dhclient: it cannot stop the dhclient started by the netif service. In both case, the situation is ok, and we can proceed. * freebsd: handle case when metadata MAC local locally Handle the case where the metadata configuration comes with a MAC that does not exist locally. See: - https://github.com/canonical/cloud-init/pull/61/files/635ce14b3153934ba1041be48b7245062f21e960#r359600604 - https://github.com/canonical/cloud-init/pull/61/files/635ce14b3153934ba1041be48b7245062f21e960#r359600966 * freebsd: show up a warning if several subnet found The FreeBSD provider currently only allow one subnet per interface. * freebsd: honor the target parameter in _write_network * freebsd: log when a bad route is found * freebsd: pass _postcmds to start_services() * freebsd: updatercconf() is depercated Replace `updatercconf()` by `rhel_util.update_sysconfig_file()`. * freebsd: ensure gateway is ipv4 before using it With the legacy ENI format, an IPv6 gateway may be pushed. This instead of the expected IPv4. * freebsd: find_fallback_nic, support FB10 On FreeBSD <= 10, `ifconfig -l` ignores the down interfaces. * freebsd: use util.target_path() to load resolv.conf Ensure we access `/etc/resolv.conf`, not `etc/resolv.conf`. * freebsd: skip subnet without netmask Those are likely to be either invalid of in IPv6 format. IPv6 support will be addressed later in a new patchset. * freebsd: get_devicelist returns netif list Ensure `get_devicelist()` returns the list of known netif on FreeBSD. * replace rhel_util.update_sysconfig_file wrapper call, with a wrapper function * reverse if condition to remove an indent Co-authored-by: Igor Galić <me+github@igalic.co>

2019-11-26set_passwords: support for FreeBSD (#46)Igor Galić
Allow setting of user passwords on FreeBSD The www/chpasswd utility which we depended on for FreeBSD installations does *not* do the same thing as the equally named Linux utility. For FreeBSD, we now use the pw(8) utility (which can only process one user at a time) Additionally, we abstract expire passwd into a function, and override it in the FreeBSD distro class. Co-Authored-By: Chad Smith <chad.smith@canonical.com>
2019-09-27debian/ubuntu: add missing word to netplan/ENI headerDaniel Watkins
Specifically, add in "reboot" to make it clear what people should expect when modifying the file. This also renames the variable to indicate it is used for netplan and ENI, not just ENI. LP: #1845669
2019-07-16Support netplan renderer in Arch LinuxConrad Hoffmann
Support is for now implemented in such a way that it will fall back to the old `_write_network()` if netplan is not available on the image.
2019-05-28freebsd: ability to grow root file systemGonéri Le Bouder
- UFS file system support - GPT partition table support - add support for newfs's -L parameter (label) - move freebsd specific test from Azure to freebsd
2019-03-25net/sysconfig: write out SUSE-compatible IPv6 configRobert Schweikert
For writing IPv6 addresses to ifcfg-* the name "IPV6ADDR" is used. For secondary IPs the value for "IPV6ADDR_SECONDARIES" is set. On SUSE based distributions the names "IPADDR6" and "IPADDR6_$SOMELABEL" need to be used.
2019-03-06Support locking user with usermod if passwd is not available.Scott Moser
In some cases, the 'passwd' command might not be available, but 'usermod' might be. In debian systems both are provided by the 'passwd' package. In Redhat/Centos passwd comes from 'passwd' package while 'usermod' comes from `shadow-utils` This should just support either one with no real cost other than the check.
2019-01-30Resolve flake8 comparison and pycodestyle over-ident issuesParide Legovini
Fixes: - flake8: use ==/!= to compare str, bytes, and int literals - pycodestyle: E117 over-indented
2019-01-28sysconfig: On SUSE, use STARTMODE instead of ONBOOTRobert Schweikert
ONBOOT is not recognized on openSUSE and SUSE Linux Enterprise, add the STARTMODE setting LP: #1799540
2018-09-20Remove dead-code _write_network distro implementations.Scott Moser
Any distro that has a '_write_nework_config' method should no longer get their _write_network called at all. So lets drop that code and raise a RuntimeError any time we got there. Replace the one caller of 'apply_network' (legacy openstack path) with a call to apply_network_config after converting the ENI to network config.
2018-09-18net_util: ensure static configs have netmask in translate_network resultThomas Berger
If a DataSource provides a network configuration in version 2 and runs on a distro which does not have a network renderer class in use, then the conversion of V2 to eni results in static ip configurations with subnet prefix-length (192.168.23.1/24) rather than explicit netmask value. When sending such a config to net_util.translate_network the resulting dictionary is missing the 'netmask' key for static configured addresses breaking network configurations on multiple distributions. This patch detects static ip configurations using prefix-length and converts the format into the previous 'address' and 'netmask' parts to keep compatibility for these distribtuions until they move to the v2 network configuration. LP: #1792454
2018-09-08config: disable ssh access to a configured user accountChad Smith
Cloud config can now disable ssh access to non-root users. When defining the 'users' list in cloud-configuration a boolean 'ssh_redirect_user: true' can be provided to disable ssh logins for that user. Any ssh 'public-keys' defined in cloud meta-data will be added and disabled in .ssh/authorized_keys. Any attempts to ssh as this user using acceptable ssh keys will be presented with a message like the following: Please login as the user "ubuntu" rather than the user "youruser".
2018-09-05sysconfig: refactor sysconfig to accept distro specific templates pathsRyan Harper
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.
2018-06-19Explicitly prevent `sudo` access for user moduleJacob Bednarz
To deny a user elevated access, you can omit the `sudo` key from the `users` dictionary. This works fine however it's implicitly defined based on defaults of `cloud-init`. If the project moves to have `sudo` access allowed for all by default (quite unlikely but still possible) this will catch a few people out. This introduces the ability to define an explicit `sudo: False` in the `users` dictionary and it will prevent `sudo` access. The behaviour is identical to omitting the key. LP: #1771468
2018-04-12Implement ntp client spec with auto support for distro selectionRyan Harper
Add a base NTP client configuration dictionary and allow Distro specific changes to be merged. Add a select client function which implements logic to preferr installed clients over clients which need to be installed. Also allow distributions to override the cloud-init defaults. LP: #1749722
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.
2017-12-07pylint: 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
2017-09-05relocate 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.
2017-08-30distro: allow distro to specify a default localeRyan Harper
Currently the cloud-init default locale (en_US.UTF-8) is set by the base datasource class. This patch allows a distro to overide the fallback value with one that's available in the distro but continues to respect an image which has preconfigured a locale. - Distro object now has a get_locale method which will return a preconfigure locale setting by checking the distros locale system configuration file. If not set or not present, return the default locale of en_US.UTF-8 which retains behavior of all previous cloud-init releases. - Apply locale now handles regenerating locales or system configuration files as needed. - Adjust apply_locale logic to skip locale-regen if the specified LANG value is C.UTF-8,C, or POSIX; they do not require regeneration. - Further add unittests to exercise the default paths for Ubuntu and non-ubuntu paths to validate they get the LANG expected.
2017-08-30suse: Add support for openSUSE and return SLES to a working state.Robert Schweikert
This gets initial opensuse and SLES support back to a working state. Still missing is more complete network file writing and unit tests.
2017-08-15network: add v2 passthrough and fix parsing v2 config with bonds/bridge paramsRyan Harper
If the network-config sent to cloud-init is in version: 2 format then when rendering netplan, we can pass the content through and avoid consuming network_state elements. This removes the need for trying to map many v2 features onto network state where other renderers won't be able to use anyhow (for example match parameters for multi-interface configuration and wifi configuration support). Additionally ensure we retain bond/bridge v2 configuration in network state so when rendering to eni or sysconfig we don't lose the configuration - Drop the NotImplemented wifi exception, log a warning that it works for netplan only - Adjust unittests to new code path and output - Fix issue with v2 macaddress values getting dropped - Add unittests for consuming/validating v2 configurations LP: #1709180
2017-08-01archlinux: Fix bug with empty dns, do not render 'lo' devices.Scott Moser
If no dns nameservers were provided a stack trace would occur. The changes here add some unit tests for the arch distro. Also avoids rendering an 'lo' interface. LP: #1663045 LP: #1706593
2017-07-25locale: Do not re-run locale-gen if provided locale is system default.Scott Moser
If the system configure default in /etc/default/locale is set to the same value that is provided for cloud-init's "locale" setting, then do not re-run locale-gen. This allows images built with a locale already generated to not re-run locale-gen (which can be very heavy). Also here is a fix to invoke update-locale correctly and remove the internal writing of /etc/default/locale. We were calling update-locale <locale> This ends up having no affect. The more correct invocation is: update-locale LANG=<locale> Also added some support here should we ever want to change setting LANG to setting LC_ALL (or any other key). Lastly, a test change to allow us to use assert_not_called from mock. Versions of mock in CentOS 6 do not have assert_not_called.
2017-07-19sysconfig: ipv6 and default gateway fixes.Ryan Harper
With this change, entries in IPV6ADDR and IPV6ADDR_SECONDARIES will now always be in format addr/prefix. When a subnet has a gateway will be written. If the gateway is ipv6, use the key IPV6_DEFAULTGW rather than GATEWAY. LP: #1704872
2017-07-19tests: fixes for issues uncovered when moving to python 3.6.Scott Moser
This includes a few fixes found when testing with python 3.6. - fix eni renderer when target is None This just uses the util.target_path() in the event that target is None. - change test cases to not rely on the cached result of util.get_cmdline() and other cached globals. Update the base TestCase to unset that cache. - mock calls to system_is_snappy from the create_users test cases. - drop unused _pp_root in test_simple_run.py LP: #1703697
2017-07-18sysconfig: include GATEWAY value if set in subnetRyan Harper
Render the GATEWAY= value in interface files which have a gateway in the subnet configuration. LP: #1686856
2017-06-08net: normalize data in network_state objectScott Moser
The network_state object's network and route keys would have different information depending upon how the network_state object was populated. This change cleans that up. Now: * address will always contain an IP address. * prefix will always include an integer value that is the network_prefix for the address. * netmask will be present only if the address is ipv4, and its value will always correlate to the 'prefix'.
2017-05-26net: fix reading and rendering addresses in cidr format.Dimitri John Ledkov
Input (specifically OpenStack) that had: "ip_address" : "104.130.20.155", "netmask" : "255.255.255.0" Was being rendered to netplan as '104.130.20.155/255.255.255.0'. That is now fixed to '104.130.20.155/24' Also fixed is reading of a route that had a network prefix integer in the 'netmask' rather than a netmask. LP: #1689346 LP: #1684349
2017-05-23flake8: move the pinned version of flake8 up to 3.3.0Scott Moser
This just moves flake8 and related tools up to newer versions and fixes the complaints associated with that. We added to the list of flake8 ignores: H102: do not put vim info in source files H304: no relative imports Also updates and pins the following in the flake8 environment: pep8: 1.7.0 => drop (although hacking still pulls it in). pyflakes 1.1.0 => 1.5.0 hacking 0.10.2 => 0.13.0 flake8 2.5.4 => 3.3.0 pycodestyle none => 2.3.1
2017-05-23RHEL/CentOS: Fix dual stack IPv4/IPv6 configuration.Andreas Karis
Dual stack IPv4/IPv6 configuration via config drive is broken for RHEL7. This patch fixes several scenarios for IPv4/IPv6/dual-stack with multiple IP assignment. Removes usage of unpopular IPv4 alias files and invalid IPv6 alias files. Also fix associated unit tests. LP: #1679817 LP: #1685534 LP: #1685532
2017-05-10FreeBSD: improvements and fixes for use on AzureHongjiang Zhang
This patch targets to make FreeBSD 10.3 or 11 work on Azure. The modifications abide by the rule of: * making as less modification as possible * delegate to the distro or datasource where possible. The main modifications are: 1. network configuration improvements, and movement into distro path. 2. Fix setting of password. Password setting through "pw" can only work through pipe. 3. Add 'root:wheel' to syslog_fix_perms field. 4. Support resizing default file system (ufs) 5. copy cloud.cfg for freebsd to /etc/cloud/cloud.cfg rather than /usr/local/etc/cloud/cloud.cfg. 6. Azure specific changes: a. When reading the azure endpoint, search in a different path and read a different option name (option-245 vs. unknown-245). so, the lease file path should be generated according to platform. b. adjust the handling of ephemeral mounts for ufs filesystem and for finding the ephemeral device. c. fix mounting of cdrom LP: #1636345
2017-03-21Fix unit test when running in a system deployed with cloud-init.Scott Moser
test_netconfig.py:test_apply_network_config_eni_ub would attempt to remove any .link files that cloud-init had written. This was just a failure to mock out all of its interaction with the host.
2017-03-20cloudinit.net: add network config v2 parsing and renderingRyan Harper
Network configuration version 2 format is implemented in a package called netplan (nplan)[1] which allows consolidated network config for multiple network controllers. - Add a new netplan renderer - Update default policy, placing eni and sysconfig first This requires explicit policy to enable netplan over eni on systems which have both (Yakkety, Zesty, UC16) - Allow any network state (parsed from any format cloud-init supports) to render to v2 if system supports netplan. - Move eni's _subnet_is_ipv6 to common code for use by other renderers - Make sysconfig renderer always emit /etc/syconfig/network configuration - Update cloud-init.service systemd unit to also wait on systemd-networkd-wait-online.service 1. https://lists.ubuntu.com/archives/ubuntu-devel/2016-July/039464.html
2017-03-07net: do not raise exception for > 3 nameserversLars Kellogg-Stedman
log a warning rather than raising ValueError if we see more than three nameserver addresses. LP: #1670052
2017-01-24tests: remove executable bit on test_net, so it runs, and fix it.Scott Moser
The test_user_data_normalize and test_net files had gotten the executable bit set, and thus are skipped by nose by default. We could set run with the --exe flag, but they should not have gotten this way. Other changes here: * replace TempDirTestCase with CiTestCase, which has some nice tmp_dir() and tmp_path() functions. Going forward the intent is to have CiTestCase be the base test case for tests. * test_net: switch to CiTestCase and fix usage that was silently broken, because of exe bit. * populate_dir: return the list of files that it writes rather than having no return value. * CiTestCase: * support tmp_path("foo") that returns a full path to 'foo' under a tmpdir. * add tmp_dir() to get a temp dir and clean up.
2016-12-22LICENSE: Allow dual licensing GPL-3 or Apache 2.0Jon Grimm
This has been a recurring ask and we had initially just made the change to the cloud-init 2.0 codebase. As the current thinking is we'll just continue to enhance the current codebase, its desirable to relicense to match what we'd intended as part of the 2.0 plan here. - put a brief description of license in LICENSE file - put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0 - simplify the per-file header to reference LICENSE - tox: ignore H102 (Apache License Header check) Add license header to files that ship. Reformat headers, make sure everything has vi: at end of file. Non-shipping files do not need the copyright header, but at the moment tests/ have it.
2016-12-19user-groups: fix bug when groups was provided as string and had spacesScott Moser
Cloud-config provided like: users: - default - name: foobar groups: sudo, adm Would result in adduser being called as: useradd foobar --groups 'sudo, adm' -m Which would cause error: useradd: group ' adm' does not exist The fix here is just to always normalize groups and remove whitespace. Additionally a fix and unit tests to explicitly set system=False or no_create_home=True. Previously those paths did not test the value of the entry, only the presense of the entry. LP: #1354694
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.
2016-10-19Move user/group functions to new ug_util fileJoshua Harlow
The amount of code to do user and group normalization and extraction deserves its own file so move the code that does this to a new file and update references to the old location. This removes some of the funkyness done in config modules to avoid namespace and attribute clashes as well.
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.
