A convenient Chef LWRP to manage user accounts and SSH keys. This is not the Opscode users cookbook.
- Website: http://fnichol.github.io/chef-user/
- Opscode Community Site: http://community.opscode.com/cookbooks/user
- Source Code: https://github.com/fnichol/chef-user
Simply include this cookbook as a dependency in metadata.rb and the user_account
resource will be available. Example:
# In your_cookbook/metadata.rb
depends 'user'
# In your_cookbook/recipes/default.rb
user_account 'hsolo' do
ssh_keygen true
end
To use recipe[user::data_bag], include it in your run_list and have a
data bag called "users" with an item like the following:
{
"id" : "hsolo",
"comment" : "Han Solo",
"home" : "/opt/hoth/hsolo",
"groups" : ["admin", "www-data"],
"ssh_keys" : ["123...", "456..."]
}
or a user to be removed:
{
"id" : "lando",
"action" : "remove"
}
If you have a username containing a period, use a dash in the data bag item
and set a username attribute:
{
"id" : "luke-skywalker",
"username" : "luke.skywalker",
"action" : ["create", "lock"]
}
The data bag recipe will iterate through a list of usernames defined in
node['users'] (by default) and attempt to pull in the user's information
from the data bag item. In other words, having:
node['users'] = ['hsolo', 'lando', 'luke.skywalker']
will set up the hsolo user information and not use the lando user
information.
Tested on 0.10.8 but newer and older version should work just fine. File an issue if this isn't the case.
The following platforms have been tested with this cookbook, meaning that the recipes run on these platforms without error:
- ubuntu
- debian
- mac_os_x
There are no external cookbook dependencies.
Depending on the situation and use case there are several ways to install this cookbook. All the methods listed below assume a tagged version release is the target, but omit the tags to get the head of development. A valid Chef repository structure like the Opscode repo is also assumed.
To install this cookbook from the Community Site, use the knife command:
knife cookbook site install user

This recipe is a no-op and does nothing.
Processes a list of users with data drawn from a data bag. The default data bag
is users and the list of user account to create on this node is set on
node['users'].
The default parent path of a user's home directory. Each resource can override
this value which varies by platform. Generally speaking, the default value is
"/home".
The default user shell given to a user. Each resource can override this value
which varies by platform. Generally speaking, the default value is
"/bin/bash".
The default Unix permissions applied to a user's home directory.
The default is "2755".
Whether of not to manage the home directory of a user by default. Each resource can override this value. The are 2 valid states:
"true",true, or"yes": will manage the user's home directory."false",false, or"no": will not manage the user's home directory.
The default is true.
Whether of not to allow the creation of a user account with a duplicate UID. Each resource can override this value. The are 2 valid states:
"true",true, or"yes": will allow duplicate UIDs."false",false, or"no": will not allow duplicate UIDs.
The default is false.
Whether or not to to create a group with the same name as the user by default. Each resource can override this value. The are 2 valid states:
"true",true, or"yes": will create a group for the user by default."false",false, or"no": will not create a group for the user by default.
The default is true.
Whether or not to generate an SSH keypair for the user by default. Each resource can override this value. There are 2 valid states:
"true",true, or"yes": will generate an SSH keypair when the account is created."false",false, or"no": will not generate an SSH keypair when the account is created.
The default is true.
The data bag name containing a group of user account information. This is used
by the data_bag recipe to use as a database of user accounts.
The default is "users".
The node attributes containing an array of users to be managed. If a nested
hash in the node's attributes is required, then use a / between subhashes.
For example, if the users' array is stored in node['system']['accounts']),
then set node['user']['user_array_node_attr'] to "system/accounts".
The default is "users".
Note: in order to use the password attribute, you must have the
ruby-shadow gem installed. On Debian/Ubuntu you can get
this by installing the "libshadow-ruby1.8" package.
