Roles

StackState Self-hosted v5.1.x

Overview

Every user in StackState needs to have a subject and a set of permissions assigned; this combination is called a role. A role describes a group of users that can access a specific data set. StackState ships with four predefined roles and you can also create custom names and groups to match your needs.

Predefined roles

There are four roles predefined in StackState:

Administrator - has full access to all views and has all permissions, except for platform management.
Platform Administrator - has platform management permissions and access to all views.
Power User - typically granted to a user that needs to configure StackState for a team(s), but won't manage the entire StackState installation.
Guest - has read-only access to StackState.

The permissions assigned to each predefined StackState role can be found below. For details of the different permissions and how to manage them using the stac CLI, see RBAC permissions

The Administrator role (stackstate-admin): has all permissions assigned, except for access-admin-api, which is assigned only to the Platform Administrator predefined role.

Permissions assigned to the predefined Administrator role (stackstate-admin) are listed below, these were retrieved using the sts CLI. For details of the different permissions and how to manage them using the sts CLI, see RBAC permissions.

The Guest role (stackstate-guest) has read-only access to StackState.

Custom roles

Custom names for predefined roles

In addition to the default predefined role names (stackstate-admin, stackstate-platform-admin, stackstate-power-user, stackstate-guest), which are always available, custom role names can be added that have the same permissions. Below is an example of how to do this for both Kubernetes and Linux installations.

Include this YAML snippet in an authentication.yaml when customizing the authentication configuration to extend the default role names with these custom role names.

stackstate:
  authentication:
    roles:
      guest: ["custom-guest-role"]
      powerUser: ["custom-power-user-role"]
      admin: ["custom-admin-role"]
      platformAdmin: ["custom-platform-admin-role"]

To use it in for your StackState installation (or already running instance, note that it will restart the API):

helm upgrade \
  --install \
  --namespace stackstate \
  --values values.yaml \
  --values authentication.yaml \
stackstate \
stackstate/stackstate

To extend the default role names with custom role names:

Edit the existing keys in the authorization section of the configuration file application_stackstate.conf.

Add custom roles using the syntax xxxGroups = ${stackstate.authorization.xxxGroups} ["custom-role"] as shown in the example below.

authorization {
 guestGroups = ${stackstate.authorization.guestGroups} ["custom-guest-role"]
 powerUserGroups = ${stackstate.authorization.powerUserGroups} ["custom-power-user-role"]
 adminGroups = ${stackstate.authorization.adminGroups} ["custom-admin-role"]
 platformAdminGroups = ${stackstate.authorization.platformAdminGroups} ["custom-platform-admin-role"]
}

Restart StackState for changes to take effect.
The list of roles will be extended to include the new, custom roles. The default roles will remain available (stackstate-admin, stackstate-platform-admin, stackstate-guest and stackstate-power-user).

Create custom roles and groups

The instructions below will take you through the process of setting up a new group called StackStateManager

Subjects need two pieces of information: a subject name and a subject scope. Create a new subject - set its name to stackstateManager and set the scope to 'label = "StackState" AND type = "Business Application”’ as in the following example:
```
# `stac` CLI:
stac subject save stackstateManager 'label = "StackState" AND type = "Business Application"'

# new `sts` CLI:
sts rbac create-subject --subject stackstateManager --scope 'label = "StackState" AND type = "Business Application"'
```
Please note that when passing an STQL query in a stac or sts CLI command, all operators (like =, <,AND, and so on) need to be surrounded by spaces, as in the above example.
Also, please note that the subject's name is case-sensitive.
Configured subjects need permissions to access parts of the UI and to execute actions in it. StackState Manager role requires access to the specific view of business applications, and there is no need to grant any CRUD, or StackPack permissions - they won't be used in day-to-day work by any Manager. To grant permission to view the Business Applications view, follow the below example:
```
# `stac` CLI:
stac permission grant stackstateManager access-view "Business Applications"

# new `sts` CLI:
sts rbac grant --subject stackstateManager --resource "Business Applications" --permission access-view
```
Please note that the subject's name, as well as permissions, are case-sensitive.

File-based authentication

If your StackState instance is configured with a file-based authentication, then you need to add newly created subjects to the config file and enable authentication.

In the application_stackstate.conf file locate the authentication block and change enabled = false to enabled = true as in the below example:
```
   authentication {
     enabled  = true
     ...
   }
```

Add new users and subjects to the logins table in the application_stackstate.conf as shown in the example below. Note that the default roles are always available (stackstate-admin, stackstate-platform-admin, stackstate-power-user and stackstate-guest)

 authentication {
   enabled  = true

   basicAuth = false

   # Amount of time to keep a session when a user doesn't log in
   sessionLifetime = 7d

   authServer {
     authServerType = "stackstateAuthServer"

     stackstateAuthServer {
       # echo -n "password" | md5sum
       # Open http://www.md5.net/md5-generator/
       # Enter your password and press submit, you will get an MD5 Hash
       # Set the MD5 Hash into `auth.password`
       logins = [
       { username = "admin", password: "5f4dcc3b3mn765d61d8327deb882cd78", roles = ["stackstate-admin"] }
       { username = "guest", password: "5f4dcc3b5aa765d61d8327deb882cf99", roles = ["stackstate-guest"] }
       { username = "manager", password: "3g4dcc3b5aa765d61g5537deb882cf99", roles = ["stackstateManager"] }
       ]
     }
   }
 }
