The default recipe configures the /etc/sudoers
file. The cookbook also includes a sudo resource to adding and removing individual sudo entries.

Use the sudo resource to add or remove individual sudo entries using sudoers.d files.
Note Sudo version 1.7.2 or newer is required to use the sudo resource as it relies on the "#includedir" directive introduced in version 1.7.2. The resource does not enforce installing the version. Supported releases of Ubuntu, Debian and RHEL (6+) all support this feature.

Property | Description | Example Value | Default Value |
---|---|---|---|
filename |
name of the /etc/sudoers.d file |
restart-tomcat | resource's name |
commands |
array of commands this sudoer can execute | ['/etc/init.d/tomcat restart'] | ['ALL'] |
groups |
group(s) to provide sudo privileges to. This accepts either an array or a comma separated list. Leading % on group names is optional. This property was named 'group' prior to the 5.1 cookbook release. | %admin,superadmin | [] |
nopasswd |
allow running sudo without specifying a password sudo | true | false |
noexec |
prevents commands from shelling out | true | false |
runas |
User the command(s) can be run as | root | ALL |
template |
the erb template to render instead of the default | restart-tomcat.erb | |
users |
user(s) to provide sudo privileges to. This accepts either an array or a comma separated. This property was named 'user' prior to the 5.1 cookbook release. list. | [tomcat, webapp] | [] |
defaults |
array of defaults this user has | ['!requiretty','env_reset'] | |
setenv |
whether to permit the preserving of environment with sudo -E |
true | false |
env_keep_add |
array of strings to add to env_keep | ['HOME', 'MY_ENV_VAR MY_OTHER_ENV_VAR'] | |
env_keep_subtract |
array of strings to remove from env_keep | ['DISPLAY', 'MY_SECURE_ENV_VAR'] | |
variables |
the variables to pass to the custom template. Ignored if not using a custom template. | commands: ['/etc/init.d/tomcat restart'] |
If you use the template property, all other properties will be ignored except for the variables property.
sudo 'bob' do
user 'bob'
end
sudo "sysadmin" do
group "sysadmin"
nopasswd true
end
sudo "sysadmin" do
group ['sysadmin', 'superadmin']
user "bob"
nopasswd true
end
The resource provides two methods for templating the sudoers config files:
- Using the built-in template
- Using a custom, cookbook-level template
Both methods will create the /etc/sudoers.d/#{resourcename}
files with the correct permissions.
The resource also performs fragment validation. If a sudoer-fragment is not valid, the Chef run will throw an exception and fail. This ensures that your sudoers file is always valid and cannot become corrupt (from this cookbook).
sudo 'tomcat' do
user '%tomcat' # or a username
runas 'app_user' # or 'app_user:tomcat'
commands ['/etc/init.d/tomcat restart']
end
sudo 'tomcat' do
template 'my_tomcat.erb' # local cookbook template
variables cmds: ['/etc/init.d/tomcat restart']
end
In either case, the following file would be generated in /etc/sudoers.d/tomcat
# This file is managed by Chef for node.example.com
# Do NOT modify this file directly.
%tomcat ALL=(app_user) /etc/init.d/tomcat restart
We highly recommend using the sudo resource to define individual sudo entries, but this cookbook also ships with a recipe that can be included on a run_list and controlled using attributes.
node['authorization']['sudo']['groups']
- groups to enable sudo access (default:[]
)node['authorization']['sudo']['users']
- users to enable sudo access (default:[]
)node['authorization']['sudo']['passwordless']
- use passwordless sudo (default:false
)node['authorization']['sudo']['include_sudoers_d']
- include and manage/etc/sudoers.d
(default:true
on Linux systems. Note: older / EOL distros do not support this feature)node['authorization']['sudo']['agent_forwarding']
- preserveSSH_AUTH_SOCK
when sudoing (default:false
)node['authorization']['sudo']['sudoers_defaults']
- Array ofDefaults
entries to configure in/etc/sudoers
node['authorization']['sudo']['setenv']
- Whether to permit preserving of environment withsudo -E
(default:false
)
To use attributes for defining sudoers, set the attributes above on the node (or role) itself:
{
"default_attributes": {
"authorization": {
"sudo": {
"groups": ["admin", "wheel", "sysadmin"],
"users": ["jerry", "greg"],
"passwordless": "true"
}
}
}
}
{
"default_attributes": {
"authorization": {
"sudo": {
"command_aliases": [{
"name": "TEST",
"command_list": [
"/usr/bin/ls",
"/usr/bin/cat"
]
}],
"custom_commands": {
"users": [
{
"user": "test_user",
"passwordless": true,
"command_list": [
"TEST"
]
}
],
"groups": [
{
"group": "test_group",
"passwordless": false,
"command_list": [
"TEST"
]
}
]
}
}
}
}
}
# roles/example.rb
default_attributes(
"authorization" => {
"sudo" => {
"groups" => ["admin", "wheel", "sysadmin"],
"users" => ["jerry", "greg"],
"passwordless" => true
}
}
)
Note that the template for the sudoers file has the group "sysadmin" with ALL:ALL permission, though the group by default does not exist.
Configure a node attribute, node['authorization']['sudo']['sudoers_defaults']
as an array of Defaults
entries to configure in /etc/sudoers
. A list of examples for common platforms is listed below:
Debian
node.default['authorization']['sudo']['sudoers_defaults'] = ['env_reset']
Ubuntu
node.default['authorization']['sudo']['sudoers_defaults'] = [
'env_reset',
'secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"'
]
FreeBSD
node.default['authorization']['sudo']['sudoers_defaults'] = [
'env_reset',
'secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"'
]
RHEL family 6.x
node.default['authorization']['sudo']['sudoers_defaults'] = [
'!visiblepw',
'env_reset',
'env_keep = "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"',
'env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"',
'env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"',
'env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"',
'env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"',
'env_keep += "HOME"',
'always_set_home',
'secure_path = /sbin:/bin:/usr/sbin:/usr/bin'
]
Mac OS X
node.default['authorization']['sudo']['sudoers_defaults'] = [
'env_reset',
'env_keep += "BLOCKSIZE"',
'env_keep += "COLORFGBG COLORTERM"',
'env_keep += "__CF_USER_TEXT_ENCODING"',
'env_keep += "CHARSET LANG LANGUAGE LC_ALL LC_COLLATE LC_CTYPE"',
'env_keep += "LC_MESSAGES LC_MONETARY LC_NUMERIC LC_TIME"',
'env_keep += "LINES COLUMNS"',
'env_keep += "LSCOLORS"',
'env_keep += "TZ"',
'env_keep += "DISPLAY XAUTHORIZATION XAUTHORITY"',
'env_keep += "EDITOR VISUAL"',
'env_keep += "HOME MAIL"'
