Configures Sudo with files in the directory /etc/sudoers.d/* containing user, host, and command aliases as well as rules. Furthermore is creates a file /etc/sudoers to source all files within this directory.

↪ attributes/sudo.rb
↪ recipes/sudo.rb
↪ definitions/sys_sudo.rb
↪ templates/*/etc_sudoers.erb
↪ templates/*/etc_network_sudoers.d_generic.erb
↪ tests/roles/sys_sudo_test.rb

The following code deploys a file called /etc/sudoers.d/admin.

sys_sudo "admin" do
  users 'ADMIN' => ["joe","bob","ted"]
  rules(
    "ADMIN ALL = NOPASSWD: /usr/bin/chef-client",
    "ADMIN ALL = ALL"
  )
end

It defines an User_Alias called "ADMIN" and a pair of rules for this group of users.

Similar the following code deploys a file /etc/sudoers.d/monitor including Cmnd_Aliass and a single rule:

sys_sudo "monitor" do
   commands(
     "IB" => [ "/usr/sbin/perfquery" ],
     "NET" => [ "/bin/netstat", "/usr/sbin/iftop", "/sbin/ifconfig" ]
   )
   rules ["mon LOCAL = NOPASSWD: IB, NET"]
end

The sys_sudo resource supports users, hosts, commands, and rules.

All attributes in node['sys']['sudo'][_stanza_]:

• defaults (optional) define some Defaults
• config (optional) defines some configuration options.
• users (optional) defines a hash of user aliases.
• hosts (optional) defines a hash of host aliases.
• commands (optional) defines a hash of command aliases.
• rules (required) defines an array of rules.

Configure command execution for a group of administrators:

"sys" => {
  "sudo" => {
    "admin" => {
      "users" => { "ADMIN" => ["joe","bob","ted"] },
      defaults: { user: 'ADMIN', option: 'env_keep += HTTP_PROXY' }
      "rules" => [
        "ADMIN ALL = NOPASSWD: /usr/bin/chef-client",
        "ADMIN ALL = ALL"
      ]
    },
    "monitor" => {
      "commands" => {
        "IB" => [ "/usr/sbin/perfquery" ],
        "NET" => [ "/bin/netstat", "/usr/sbin/iftop", "/sbin/ifconfig" ]
      },
      "rules" => [ "mon LOCAL = NOPASSWD: IB, NET" ]
    },
    "users" => {
      "users" => { "KILLERS" => ["maria","anna"] },
      "hosts" => { "LAN" => ["10.1.1.0/255.255.255.0"] },
      "commands" => {
        "KILL" => [ "/usr/bin/kill", "/usr/bin/killall" ],
        "SHUTDOWN" => [ "/usr/sbin/shutdown", "/usr/sbin/reboot" ]
      },
      "rules" => [
        "KILLERS LOCAL = KILL",
        "%users LAN = SHUTDOWN"
      ]
    }
  }
}

Furthermore some extra command for a monitoring user mon, and extra privileges for users.

node['sys']['sudo']['config'] accepts the following attributes for email notification setup:

• mailfrom: the sender address - default: the offending account
• mailto: the recipient address - default: root
• mailsub the notification email subject

node['sys']['sudo']['config']['cleanup'] controls whether all files in /etc/sudoers.d/ shall be managed by sys::sudo. Setting it to true will delete all files in /etc/sudoers.d/ where no corresponding node['sys']['sudo'][…] attributes are defined.
