A more complex example is to create a *series* of clusters such

as:

In the example above, we provision 3 clusters that have a number appended

into their resulting cluster name, apply a user defined label to each

cluster, and also apply user defined policies to each cluster after

they are created.

Selectors can be used to perform backups as well, for example:

In this example, any cluster that matches the selector will cause

a backup job to be created.

Selectors also apply to the delete command as follows:

This command will cause any cluster matching the selector

to be removed.

To assign users to a cluster:

In this example, a user named *user1* is created with a *valid until* password date set to expire in 30 days. That user will be granted access to the *userdb* database. This user account also will have an associated *secret* created to hold the password that was generated for this user. Any clusters that match the selector value will have this user created on it.

To change a user password:

In this example, a user named *user1* has its password changed to a generated

value and the *valid until* expiration date set to 10 days from now, this

command will take effect across all clusters that match the selector.

To drop a user:

To see which passwords are set to expire in a given number of days:

To check password age:

In this example, any clusters that match the selector are queried to see

if any users are set to expire in 10 days.

== Label Management

You can apply a user defined label to a cluster as follows:

In this example, we apply a label of *env=research* to any

clusters that have an existing label of *project=xray* applied.
