Saltstack sample of using states and pillars for users

saltsample_09252012_01

Here is a sample of how I am currently dealing with users.

Big thanks to uggedal! I used his user states as an example: https://github.com/uggedal/states

# How to create password hashes

python -c "import crypt; print crypt.crypt('password', '\$6\$SALTsalt\$')"

###
# top.sls in pillars

base:
  '*':
    - groups
    - users

# users.sls

users:
  user1:
    fullname: Robert Hernandez
    uid: 5000
    gid: 5000
    shell: /bin/bash
    home: /home/user1
    groups:
      - wheel
      - admin
    password: $6$SALTsalt$UiZikbV3VeeBPsg8./Q5DAfq9aj7CVZMDU6ffBiBLgUEpxv7LMXKbcZ9JSZnYDrZQftdG319XkbLVMvWcF/Vr/

  user2:

    - groups
    - users

{% for group, args in pillar['groups'].iteritems() %}
{{ group }}:
  group.present:
    - name: {{ group }}
{% if 'gid' in args %}
    - gid: {{ args['gid'] }}
{% endif %}
{% endfor %}
	
###
# users.sls 
###
{% for user, args in pillar['users'].iteritems() %}
{{ user }}:
  group.present:
    - gid: {{ args['gid'] }}
  user.present:
    - home: {{ args['home'] }}
    - shell: {{ args['shell'] }}
    - uid: {{ args['uid'] }}
    - gid: {{ args['gid'] }}
{% if 'password' in args %}
    - password: {{ args['password'] }}
{% if 'enforce_password' in args %}
    - enforce_password: {{ args['enforce_password'] }}
{% endif %}
{% endif %}
    - fullname: {{ args['fullname'] }}
{% if 'groups' in args %}
    - groups: {{ args['groups'] }}
{% endif %}
    - require:
      - group: {{ user }}

{% if 'key.pub' in args and args['key.pub'] == True %}
{{ user }}_key.pub:
  ssh_auth:
    - present
    - user: {{ user }}
    - source: salt://users/{{ user }}/keys/key.pub
{% endif %}
{% endfor %}

Commenting because this is one of top results on Google for 'saltstack generate password hash'. Note that the one-liner above is for Python >= 3.3 and will generate a salted hash using SHA512.

According to the documentation, Python's crypt() is an interface to OS's crypt() function. Also:
If salt is not specified or is None, the strongest
available method will be selected and a salt generated. Otherwise,
salt may be one of the crypt.METHOD_* values, or a string as
returned by crypt.mksalt().

So, simply executing
python3.4 -c "import crypt; print(crypt.crypt('password'))"
will generate a salted hash of 'password', using the strongest method available to the current OS. Which beats the script that is restricted to Linux only (why? there are others that work just fine), provided Python >= 3.3 is available. The script works on Python < 3.3 though.

Is there a way to create just a user and make his primary group to be an already existing group? I've been hacking away on this for the past few hours but can't seem to get it done. The state creates a group with a name based on the username.

EDIT: I seem to have figured that out:

{% for user, args in pillar['users'].iteritems() %}
{{ user }}:
  user.present:
    - home: {{ args['home'] }}
    - shell: {{ args['shell'] }}
    - uid: {{ args['uid'] }}
    - gid: {{ args['gid'] }}
{% if 'password' in args %}
    - password: {{ args['password'] }}
{% if 'enforce_password' in args %}
    - enforce_password: {{ args['enforce_password'] }}
{% endif %}
{% endif %}
    - fullname: {{ args['fullname'] }}
{% if 'groups' in args %}
    - groups: {{ args['groups'] }}
{% endif %}

{% if 'key.pub' in args and args['key.pub'] == True %}
{{ user }}_key.pub:
  ssh_auth:
    - present
    - user: {{ user }}
    - source: salt://users/{{ user }}/keys/key.pub
{% endif %}
{% endfor %}

Very informative example, Thank you.

I am facing some issues, I am working on multiple CM tools and all worked fine for me in Puppet and Chef. Recently doing POC on salt and stuck at password level. Though all worked fine but I am unable to use the password for login (infact /etc/shadow is also empty at password field). Could someone have a look:

[root@salt users]# cat /srv/salt/top.sls
base:
'':
- users
[root@salt users]# cat /srv/salt/users/init.sls
{% for user, args in pillar.get('users', {}).items() %}
{{user}}:
user.present:
- uid: {{ args['uid'] }}
{% if 'shell' in args %}
- shell: {{ args['shell'] }}
{% if 'passwd' in args %}
- passwd: {{ args['passwd'] }}
{% endif %}
{% endif %}
{% endfor %}
[root@salt users]# cat /srv/pillar/top.sls
base:
'':
- users
[root@salt users]# cat /srv/pillar/users/init.sls
users:
test10:
uid: 3333
shell: /sbin/nologin
test11:
uid: 3334
passwd: '$6$somesalt!$3UQn7wIuHJUkfawfTqftXADbm88MhnV/hYIcDStmcVTEzWyO4ovUe9bYcpL1Nl5ae1wagxAJEqfTMyf1dsMGA1'
test12:
uid: 3335
[root@salt users]#

PS: I tried with multiple password options, nothing worked for me.

@yogeshraheja I think you want password, not passwd.

Also be aware that there is hash_password, which is false by default. hash_password: False means that password is already hashed, but hash_password: True means that password is stored in plaintext and must be hashed by the underlying module.

@utahdav Thanks for this sharing, It really saved my day :)
