salt.wheel.key

Wheel system wrapper for the Salt key system to be used in interactions with the Salt Master programmatically.

The key module for the wheel system is meant to provide an internal interface for other Salt systems to interact with the Salt Master. The following usage examples assume that a WheelClient is available:

import salt.config
import salt.wheel
opts = salt.config.master_config('/etc/salt/master')
wheel = salt.wheel.WheelClient(opts)

Note that importing and using the WheelClient must be performed on the same machine as the Salt Master and as the same user that runs the Salt Master, unless external_auth is configured and the user is authorized to execute wheel functions.

The function documentation starts with the wheel reference from the code sample above and use the WheelClient functions to show how they can be called from a Python interpreter.

The wheel key functions can also be called via a salt command at the CLI using the saltutil execution module.

salt.wheel.key.accept(match, include_rejected=False, include_denied=False)

Accept keys based on a glob match. Returns a dictionary.

match
The glob match of keys to accept.
include_rejected
To include rejected keys in the match along with pending keys, set this to True. Defaults to False.
include_denied
To include denied keys in the match along with pending keys, set this to True. Defaults to False.
>>> wheel.cmd('key.accept', ['minion1'])
{'minions': ['minion1']}
salt.wheel.key.accept_dict(match, include_rejected=False, include_denied=False)

Accept keys based on a dict of keys. Returns a dictionary.

match
The dictionary of keys to accept.
include_rejected

To include rejected keys in the match along with pending keys, set this to True. Defaults to False.

New in version 2016.3.4.

include_denied

To include denied keys in the match along with pending keys, set this to True. Defaults to False.

New in version 2016.3.4.

Example to move a list of keys from the minions_pre (pending) directory to the minions (accepted) directory:

>>> wheel.cmd('key.accept_dict',
{
    'minions_pre': [
        'jerry',
        'stuart',
        'bob',
    ],
})
{'minions': ['jerry', 'stuart', 'bob']}

salt.wheel.key.delete_dict(match)

Delete keys based on a dict of keys. Returns a dictionary.

The dictionary of keys to delete.
>>> wheel.cmd_async({'fun': 'key.delete_dict',
'match': {
    'minions': [
        'jerry',

        'bob',
    ],
})

salt.wheel.key.finger(match, hash_type=None)

Return the matching key fingerprints. Returns a dictionary.

match
The key for with to retrieve the fingerprint.
hash_type
The hash algorithm used to calculate the fingerprint
>>> wheel.cmd('key.finger', ['minion1'])
{'minions': {'minion1': '5d:f6:79:43:5e:d4:42:3f:57:b8:45:a8:7e:a4:6e:ca'}}
salt.wheel.key.finger_master(hash_type=None)

Return the fingerprint of the master's public key

hash_type
The hash algorithm used to calculate the fingerprint
>>> wheel.cmd('key.finger_master')
{'local': {'master.pub': '5d:f6:79:43:5e:d4:42:3f:57:b8:45:a8:7e:a4:6e:ca'}}
salt.wheel.key.gen(id_=None, keysize=2048)

Generate a key pair. No keys are stored on the master. A key pair is returned as a dict containing pub and priv keys. Returns a dictionary containing the the pub and priv keys with their generated values.

id_
Set a name to generate a key pair for use with salt. If not specified, a random name will be specified.
keysize
The size of the key pair to generate. The size must be 2048, which is the default, or greater. If set to a value less than 2048, the key size will be rounded up to 2048.
>>> wheel.cmd('key.gen')
{'pub': '-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBC
...
BBPfamX9gGPQTpN9e8HwcZjXQnmg8OrcUl10WHw09SDWLOlnW+ueTWugEQpPt\niQIDAQAB\n
-----END PUBLIC KEY-----',
'priv': '-----BEGIN RSA PRIVATE KEY-----\nMIIEpAIBAAKCAQEA42Kf+w9XeZWgguzv
...
QH3/W74X1+WTBlx4R2KGLYBiH+bCCFEQ/Zvcu4Xp4bIOPtRKozEQ==\n
-----END RSA PRIVATE KEY-----'}
salt.wheel.key.gen_accept(id_, keysize=2048, force=False)

Generate a key pair then accept the public key. This function returns the key pair in a dict, only the public key is preserved on the master. Returns a dictionary.

id_
The name of the minion for which to generate a key pair.
keysize
The size of the key pair to generate. The size must be 2048, which is the default, or greater. If set to a value less than 2048, the key size will be rounded up to 2048.
force
If a public key has already been accepted for the given minion on the master, then the gen_accept function will return an empty dictionary and not create a new key. This is the default behavior. If force is set to True, then the minion's previously accepted key will be overwritten.
>>> wheel.cmd('key.gen_accept', ['foo'])
{'pub': '-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBC
...
BBPfamX9gGPQTpN9e8HwcZjXQnmg8OrcUl10WHw09SDWLOlnW+ueTWugEQpPt\niQIDAQAB\n
-----END PUBLIC KEY-----',
'priv': '-----BEGIN RSA PRIVATE KEY-----\nMIIEpAIBAAKCAQEA42Kf+w9XeZWgguzv
...
QH3/W74X1+WTBlx4R2KGLYBiH+bCCFEQ/Zvcu4Xp4bIOPtRKozEQ==\n
-----END RSA PRIVATE KEY-----'}

We can now see that the foo minion's key has been accepted by the master:

>>> wheel.cmd('key.list', ['accepted'])
{'minions': ['foo', 'minion1', 'minion2', 'minion3']}
