2020-11-20Support configuring SSH host certificates. (#660)Jonathan Lung
Existing config writes keys to /etc/ssh after deleting files matching a glob that includes certificate files. Since sshd looks for certificates in the same directory as the keys, a host certificate must be placed in this directory. This update enables the certificate's contents to be specified along with the keys. Co-authored-by: jonathan lung <lungj@heresjono.com> Co-authored-by: jonathan lung <jlung@kepler.space>
2020-08-21Update the list of valid ssh keys. (#487)Ole-Martin Bratteng
Update ssh_util.py with latest list of keys (from openssh-8.3p1/sshkey.c), Added keys: sk-ecdsa-sha2-nistp256-cert-v01@openssh.com sk-ecdsa-sha2-nistp256@openssh.com sk-ssh-ed25519-cert-v01@openssh.com sk-ssh-ed25519@openssh.com ssh-xmss-cert-v01@openssh.com ssh-xmss@openssh.com LP: #1877869
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.

2019-10-31Add config for ssh-key import and consuming user-dataPavel Zakharov
This patch enables control over SSH public-key import and discarding supplied user-data (both disabled by default). allow-userdata: false ssh: allow_public_ssh_keys: false This feature enables closed appliances to prevent customers from unintentionally breaking the appliance which were not designed for user interaction. The downstream change for this is here: https://github.com/delphix/cloud-init/pull/4

2019-08-09Add support for publishing host keys to GCE guest attributesRick Wright
This adds an empty publish_host_keys() method to the default datasource that is called by cc_ssh.py. This feature can be controlled by the 'ssh_publish_hostkeys' config option. It is enabled by default but can be disabled by setting 'enabled' to false. Also, a blacklist of key types is supported. In addition, this change implements ssh_publish_hostkeys() for the GCE datasource, attempting to write the hostkeys to the instance's guest attributes. Using these hostkeys for ssh connections is currently supported by the alpha version of Google's 'gcloud' command-line tool. (On Google Compute Engine, this feature will be enabled by setting the 'enable-guest-attributes' metadata key to 'true' for the project/instance that you would like to use this feature for. When connecting to the instance for the first time using 'gcloud compute ssh' the hostkeys will be read from the guest attributes for the instance and written to the user's local known_hosts file for Google Compute Engine instances.)
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".
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.
2016-10-19Move 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.
2016-09-30Improve 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

2014-08-26fix(pep8): Fix various pep8 violations and version-lock pep8Jay Faulkner
Fixed all complaints from running "make pep8". Also version locked pep8 in test-requirements.txt to ensure that pep8 requirements don't change without an explicit commit.
2013-06-19fix and cleanup usage of util.logexcJuerg Haefliger
2013-03-01change parser.parse 'default_opts' to 'options'Scott Moser
Now, parser.parse specifies options that override any options found, rather than just being default options. There could still potentially be a user for default_options, but since we're not using them anywhere, I've dropped it. The difference is that in setting up the root user, we're now insisting that all keys that go in there have the key_prefix, even if the key content had other options. I think this is actually the commit that fixes LP: #1136343.
2012-10-27Helpful cleanups.harlowja
1. Remove the usage of the path.join function now that all code should be going through the util file methods (and they can be mocked out as needed). 2. Adjust all occurences of the above join function to either not use it or replace it with the standard os.path.join (which can also be mocked out as needed) 3. Fix pylint from complaining about the tests folder 'helpers.py' not being found 4. Add a pylintrc file that is used instead of the options hidden in the 'run_pylint' tool.
2012-09-28Add a comment as to why distros can't beJoshua Harlow
imported without being renamed due to previous usage of the attribute 'distros'
2012-09-28Rework the rest of the locations that usedJoshua Harlow
the previous 'user' and make those locations go through the new distros functions to select the default user or the user list (depending on usage). Adjust the tests to check the new 'default' field that signifies the default user + test the new method to extract just the default user from a normalized user dictionary.
2012-08-31- Converted user list to user dict to allow exclusion of the default userBen Howard
on Ubuntu systems via cloud-config (LP: #1041384). - Fixed bug with user creation on Ubuntu where the default user groups are not set properly (LP: #1044044). - Fixed documentation for user creation (LP: #1044508).
2012-08-22cc_ssh.py: add the "get user zero" logic, disable root even if no userScott Moser
cc_ssh.py was getting user of None, which ended up with a root user not getting ssh keys updated. That was bad. So, I duplicated the "get user zero" code that appeared other places here. Then, we disable the root user even if there is not a user. In that case we just use the string "NONE" in the disable message.
