Groups

Groups are used to define roles for specific sets of users in Kasm Workspaces. By default there are two groups created by the system, the Administrators group and the All Users group, the All Users group is the default group for every user where statewide settings can be set.

Groups can be used to specify Kasm images and settings for different sets of users. For example, you may have a custom image for developers with pre-installed developer tools. You can tie that image to a group. You can define settings for that group, such as enabling bi-directional clipboard.

Create Group

Steps to create individual groups for sections of users.

• Select Groups tab from navigation menu

• Select Create New Group from the top right of the table

• Specify Group properties listed below

Group Properties

Name	Provides the name of the group
Description	Provides the description of the group
Priority	Sets the priority of the settings over other groups
Is System	System level group that cannot be deleted

There are cards in the view group page that allow for the selection of its users

Group Settings

Group settings may be changed for the specific group by selecting the groups tab, clicking the edit icon on the desired group and the Add Settings button in the Group Settings card. There are delete setting and edit setting icons to the right of the Setting. If a user belongs to mulitple groups, the setting on the group with the lowest priority takes effect. For settings like volume_mapping, all settings are combined from all groups a user is a member of.

Here is a video that has an overview Groups and Group settings.

To configure group settings:

• Log into the UI as an administrator.

• Select Groups

• Next to the desired group select View from the actions menu.

• Scroll down to the Group Settings panel. Update settings as desired.

Session Time Limits

There are a multiple settings in the table above that control Kasm session lifetime. We will go into more detail about them and their relationship to each other below:

keepalive_expiration

This can also be described as the session timeout. This value determines how long Kasm will wait before destroying, stopping or pausing a session if no keepalive is received from the client. Keepalives are sent whenever a user is connected to a Kasm session even if the user is not actively using the Kasm Session. This value should be at least twice the keepalive_interval. This setting is 1 hour by default in the “All Users Group”. The action taken is determined by the keepalive_expiration_action Group Setting.

keepalive_expiration_action

Administrators can decide what happens to sessions once they expire. Valid options are:

• delete - The session is destroyed.

• pause - The session is paused, preserving the disk, process and memory state. Paused sessions will still consume resources in physical memory and/or swap. Sessions resumed from a paused state will still have the previous programs launched and active. This action is valid for container-based sessions only. All other types will utilize the delete action.

• stop - The session is stopped, preserving the disk state. Sessions resumed from a stopped state will have the previous files intact, but previously running programs will need to be restarted. This action is valid for container-based sessions only. All other types will utilize the delete action.

Note

When sessions are stopped or paused, the CPU/RAM resources on the Agent become available for other requests to create new sessions. This may lead to a user not being able to resume a paused/stopped session if the Agent’s resources become consumed by other running sessions. When using Cloud Autoscaling, the system will not destroy Agents that have stopped/paused sessions and will similarly allow other sessions to be provisioned on the Agent. If this is undesirable, the admin can ensure users are not given the allow_kasm_pause and allow_kasm_stop permissions.

keepalive_interval

The keepalive_interval is how often the client will send a keepalive request to Kasm when the user is actively using a session. This setting is 300 seconds by default for the “All Users Group”.

idle_disconnect

This setting is the number of minutes Kasm will wait when the user is idle before logging the user out of Kasm. Once the user is logged out, any Kasm sessions that the user was connected to will be disconnected and those sessions will be subject to the keepalive_expiration. This setting is set to 20 minutes by default in the “All Users Group”

usage_limit

The usage_limit setting is a highly flexible option allowing the administrator to configure a maximum usage number of hours either for each user in the group or for the entire group collectively to use over a set time period. This setting is a decimal value. When using the usage_limit setting all time that a Kasm session is running is counted against the total, this includes when the user is not actively connected to the session but the session is still running. This setting is for use cases where user workspace access should be metered. This setting is not enabled by default.

Note

Accounting for paused/stopped sessions are left as is. Users are “charged” for the full duration of the session, even if the session is paused or stopped.

The user can see how much time they have used/have remaining on the user dashboard:

Session Time Usage

Clicking on this icon will bring up a more detailed display.

Detailed Session Time Usage

session_time_limit

The session_time_limit is a set amount of time that a workspace will be allowed to run once that workspace is created. This time limit is irrespective of whether the user is actively using the session or if the session is disconnected and running in the background. When session_time_limit is configured, the keepalive_expiration setting is not used. This setting is not enabled by default

Session Time Limit Countdown

Group Workspaces

Administrators can define which Workspaces are available to each group. By default newly created workspaces are automatically assigned to the All Users group. This behavior can be changed by modifying the Add Images To Default Group global Settings.

SSO Group Mappings

Administrators can configure the system to automatically map users that authenticate with an SSO provider (e.g SAML, OpenID, LDAP) into Kasm Groups.

If Assign All Users is selected, any user that authenticates with the defined SSO provider will be added to the Kasm group. Otherwise, only users that have the defined Group Attributes passed in by the SSO provider will be added to the group.

These group mappings are evaluated and updated at each user login. If a mapping is defined and a user does not have the group attributes listed, the user will be removed from the group.

Group File Mappings

File Mappings allow the administrator to manage files to be mapped to the inside of a user’s container based Workspace session. File Mappings can be defined on a User, Group, and/or Workspace. See the primary documentation on File mappings for more details.

Note

When a user belongs to multiple Groups that define a File Mapping with the same destination, the group with the lowest priority value gets mapped into the user’s container.
