Users Command

If you use file-based user authentication, the users command enables you to add and remove users, assign user roles, and manage passwords.

Synopsis

bin/x-pack/users
([useradd <username>] [-p <password>] [-r <roles>]) |
([list] <username>) |
([passwd <username>] [-p <password>]) |
([roles <username>] [-a <roles>] [-r <roles>]) |
([userdel <username>])

Description

If you use the built-in file internal realm, users are defined in local files on each node in the cluster.

Usernames and roles must be at least 1 and no more than 1024 characters. They can contain alphanumeric characters (a-z, A-Z, 0-9), spaces, punctuation, and printable symbols in the Basic Latin (ASCII) block. Leading or trailing whitespace is not allowed.

Passwords must be at least 6 characters long.

For more information, see File-based User Authentication.

To ensure that Elasticsearch can read the user and role information at startup, run users useradd as the same user you use to run Elasticsearch. Running the command as root or some other user updates the permissions for the users and users_roles files and prevents Elasticsearch from accessing them.

Parameters

-a <roles>: If used with the roles parameter, adds a comma-separated list of roles to a user.

list

List the users that are registered with the file realm on the local node. If you also specify a user name, the command provides information for that user.

-p <password>

Specifies the user’s password. If you do not specify this parameter, the command prompts you for the password.

Omit the -p option to keep plaintext passwords out of the terminal session’s command history.

passwd <username>

Resets a user’s password. You can specify the new password directly with the -p parameter.

-r <roles>

If used with the useradd parameter, defines a user’s roles. This option accepts a comma-separated list of role names to assign to the user.
If used with the roles parameter, removes a comma-separated list of roles from a user.

roles

Manages the roles of a particular user. You can combine adding and removing roles within the same command to change a user’s roles.

useradd <username>: Adds a user to your local node.
userdel <username>: Deletes a user from your local node.

Examples

The following example adds a new user named jacknich to the file realm. The password for this user is theshining, and this user is associated with the network and monitoring roles.

bin/x-pack/users useradd jacknich -p theshining -r network,monitoring

The following example lists the users that are registered with the file realm on the local node:

bin/x-pack/users list
rdeniro        : admin
alpacino       : power_user
jacknich       : monitoring,network

Users are in the left-hand column and their corresponding roles are listed in the right-hand column.

The following example resets the jacknich user’s password:

bin/x-pack/users passwd jachnich

Since the -p parameter was omitted, the command prompts you to enter and confirm a password in interactive mode.

The following example removes the network and monitoring roles from the jacknich user and adds the user role:

bin/x-pack/users roles jacknich -r network,monitoring -a user

The following example deletes the jacknich user:

bin/x-pack/users userdel jacknich
