Use the user resource to add users, update existing users, remove users, and to lock/unlock user passwords.
Did some debugging on Mac OS X Mavericks and the install.sh 'Omnibus installer' creates a temp directory containing chef-macosx-10.7-x8664.sh (10.7 atm) that creates another temp directory containing makeselfinst that has DESTDIR=/opt/chef in it. So that's true, deleting /opt/chef removes it but there will be some symlinks in /usr/bin pointing to nowhere you might also want to remove. If you want the equivalent of apt-get or yum on Mac OS X, you have two choices. You can use brew install PACKAGENAME or port install PACKAGENAME to install the package available. You need to install either Homebrew or YUM. To install Homebrew enter the following command in terminal.
Note
System attributes are collected by Ohai at the start of every chef-client run. By design, the actions available to the user resource are processed after the start of the chef-client run. This means that system attributes added or modified by the user resource during the chef-client run must be reloaded before they can be available to the chef-client. These system attributes can be reloaded in two ways: by picking up the values at the start of the (next) chef-client run or by using the ohai resource to reload the system attributes during the current chef-client run.
Syntax¶
A user resource block manages users on a node:
The full syntax for all of the properties that are available to the user resource is:
where
- user is the resource
- name is the name of the resource block
- :action identifies the steps the chef-client will take to bring the node into the desired state
- comment, force, gid, home, iterations, manage_home, non_unique, password, provider, salt, shell, system, uid, and username are properties of this resource, with the Ruby type shown. See 'Properties' section below for more information about all of the properties that may be used with this resource.
Chef Yum Mac Os Catalina
Actions¶
This resource has the following actions:
- :create
- Default. Create a user with given properties. If a user already exists (but does not match), update that user to match.
- :lock
- Lock a user's password.
- :manage
- Manage an existing user. This action does nothing if the user does not exist.
- :modify
- Modify an existing user. This action raises an exception if the user does not exist.
- :nothing
- Define this resource block to do nothing until notified by another resource to take action. When this resource is notified, this resource block is either run immediately or it is queued up to be run at the end of the chef-client run.
- :remove
- Remove a user.
- :unlock
- Unlock a user's password.
Properties¶
This resource has the following properties:
Ruby Type: String
One (or more) comments about the user.
Ruby Types: TrueClass, FalseClass
Force the removal of a user. May be used only with the :remove action.
Warning
Using this property may leave the system in an inconsistent state. For example, a user account will be removed even if the user is logged in. A user's home directory will be removed, even if that directory is shared by multiple users.
Ruby Types: String, Integer
The identifier for the group.
Ruby Types: String, Integer
The group property is an alias of the gid property.
Ruby Type: String
The location of the home directory.
Ruby Types: TrueClass, FalseClass
Continue running a recipe if a resource fails for any reason. Default value: false.
Ruby Type: Integer
Mac OS X platform only, 10.8 (or higher). The number of iterations for a password with a SALTED-SHA512-PBKDF2 shadow hash.
Ruby Types: TrueClass, FalseClass
Manage a user's home directory.
With the :create action, a user's home directory is created based on HOME_DIR. If the home directory is missing, it is created unless CREATE_HOME in /etc/login.defs is set to no. When created, a skeleton set of files and sub-directories is also created in the home directory.
With the :modify action, a user's home directory is moved to HOME_DIR. If the home directory is missing, it is created unless CREATE_HOME in /etc/login.defs is set to no. The contents of the user's home directory are moved to the new location.
Ruby Types: TrueClass, FalseClass
Create a duplicate (non-unique) user account.
Ruby Type: Symbol, ‘Chef::Resource[String]'
A resource may notify another resource to take action when its state changes. Specify a 'resource[name]', the :action that resource should take, and then the :timer for that action. A resource may notifiy more than one resource; use a notifies statement for each resource to be notified.
A timer specifies the point during the chef-client run at which a notification is run. The following timers are available:
- :before
- Specifies that the action on a notified resource should be run before processing the resource block in which the notification is located.
- :delayed
- Default. Specifies that a notification should be queued up, and then executed at the very end of the chef-client run.
- :immediate, :immediately
- Specifies that a notification should be run immediately, per resource notified.
The syntax for notifies is:
Ruby Type: String
The password shadow hash. This property requires that ruby-shadow be installed. This is part of the Debian package: libshadow-ruby1.8.
Ruby Type: Chef Class
Optional. Explicitly specifies a provider. See 'Providers' section below for more information.
Ruby Type: Integer
The number of times to catch exceptions and retry the resource. Default value: 0.
Ruby Type: Integer
The retry delay (in seconds). Default value: 2.
Ruby Type: String
Mac OS X platform only, 10.7 or higher. The salt value for a password shadow hash. Mac OS X version 10.7 uses SALTED-SHA512 and version 10.8 (and higher) uses SALTED-SHA512-PBKDF2 to calculate password shadow hashes.
Ruby Type: String
The login shell.
Chef Yum Mac Os Download
Ruby Type: Symbol, ‘Chef::Resource[String]'
A resource may listen to another resource, and then take action if the state of the resource being listened to changes. Specify a 'resource[name]', the :action to be taken, and then the :timer for that action.
A timer specifies the point during the chef-client run at which a notification is run. The following timers are available:
Chef Yum Mac Os X
- :before
- Specifies that the action on a notified resource should be run before processing the resource block in which the notification is located.
- :delayed
- Default. Specifies that a notification should be queued up, and then executed at the very end of the chef-client run.
- :immediate, :immediately
- Specifies that a notification should be run immediately, per resource notified.
The syntax for subscribes is:
Ruby Types: TrueClass, FalseClass
Create a system user. This property may be used with useradd as the provider to create a system user which passes the -r flag to useradd.
Ruby Types: String, Integer
Crazy bike 2 mac os. The numeric user identifier.
Ruby Type: String
The name of the user. Default value: the name of the resource block See 'Syntax' section above for more information.
Supported Features¶
The supports attribute of the user resource has been deprecated. The supports[:manage_home] property was an aliasfor the manage_home property, while the supports[:non_unique] property was an alias for the non_unique property.
Password Shadow Hash¶
There are a number of encryption options and tools that can be used to create a password shadow hash. In general, using a strong encryption method like SHA-512 and the passwd command in the OpenSSL toolkit is a good approach, however the encryption options and tools that are available may be different from one distribution to another. The following examples show how the command line can be used to create a password shadow hash. When using the passwd command in the OpenSSL tool:
When using mkpasswd:
Chef Yum Mac Os Download
For more information:
- Check the local documentation or package repository for the distribution that is being used. For example, on Ubuntu 9.10-10.04, the mkpasswd package is required and on Ubuntu 10.10+ the whois package is required.
Providers¶
Where a resource represents a piece of the system (and its desired state), a provider defines the steps that are needed to bring that piece of the system from its current state into the desired state.
The chef-client will determine the correct provider based on configuration data collected by Ohai at the start of the chef-client run. This configuration data is then mapped to a platform and an associated list of providers.
Generally, it's best to let the chef-client choose the provider, and this is (by far) the most common approach. However, in some cases, specifying a provider may be desirable. There are two approaches:
- Use a more specific short name—yum_package'foo'do instead of package'foo'do, script'foo'do instead of bash'foo'do, and so on—when available
- Use the provider property within the resource block to specify the long name of the provider as a property of a resource. For example: providerChef::Provider::Long::Name
This resource has the following providers:
- Chef::Provider::User::Useradd, user
- The default provider for the user resource.
- Chef::Provider::User::Pw, user
- The provider for the FreeBSD platform.
- Chef::Provider::User::Dscl, user
- The provider for the Mac OS X platform.
- Chef::Provider::User::Windows, user
- The provider for all Microsoft Windows platforms.
Examples¶
The following examples demonstrate various approaches for using resources in recipes. If you want to see examples of how Chef uses resources in recipes, take a closer look at the cookbooks that Chef authors and maintains: https://github.com/chef-cookbooks.
Create a user named 'random'
Create a system user
Create a system user with a variable
The following example shows how to create a system user. In this instance, the home value is calculated and stored in a variable called user_home which sets the user's home attribute.
Use SALTED-SHA512 passwords
Mac OS X 10.7 calculates the password shadow hash using SALTED-SHA512. The length of the shadow hash value is 68 bytes, the salt value is the first 4 bytes, with the remaining 64 being the shadow hash itself. The following code will calculate password shadow hashes for Mac OS X 10.7:
Use the calculated password shadow hash with the user resource:
Use SALTED-SHA512-PBKDF2 passwords
Mac OS X 10.8 (and higher) calculates the password shadow hash using SALTED-SHA512-PBKDF2. The length of the shadow hash value is 128 bytes, the salt value is 32 bytes, and an integer specifies the number of iterations. The following code will calculate password shadow hashes for Mac OS X 10.8 (and higher):
Use the calculated password shadow hash with the user resource:
Use SALTED-SHA512-PBKDF2 passwords
Mac OS X 10.8 (and higher) calculates the password shadow hash using SALTED-SHA512-PBKDF2. The length of the shadow hash value is 128 bytes, the salt value is 32 bytes, and an integer specifies the number of iterations. The following code will calculate password shadow hashes for Mac OS X 10.8 (and higher):
Use the calculated password shadow hash with the user resource:
