Roles

SUSE Observability Self-hosted

Overview

Every user in SUSE Observability 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. SUSE Observability ships with a set of predefined roles and you can also create roles to match your needs.

Predefined roles

There are four roles predefined in SUSE Observability:

• 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 SUSE Observability for a team(s), but won't manage the entire SUSE Observability installation.

• Kubernetes Troubleshooter - has all permissions required to use SUSE Observability for troubleshooting, including the ability to enable/disable monitors, create custom views and use the Cli.

• Guest - has read-only access to SUSE Observability.

The permissions assigned to each predefined SUSE Observability role can be found below. For details of the different permissions and how to manage them using the sts CLI, see Role based access control (RBAC) permissions

Administrator

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 SUSE Observability.

❯ ./sts rbac describe-permissions --subject stackstate-guest

Custom roles

In addition to the predefined roles (stackstate-admin, stackstate-platform-admin, stackstate-power-user, stackstate-k8s-troubleshooter, stackstate-guest), which are always available, custom roles can be added. There are multiple ways to add custom roles:

1. via the configuration file, with the same permission as the predefined roles

2. via the configuration file, with a custom scope and custom system and view permissions

3. using the sts CLI, the subjects and their permissions are stored in the database and can be modified during runtime

Roles added via the configuration file require a restart and therefore result in a short period of downtime. Roles created using the CLI are stored in the database and can be modified at runtime.

Custom names for predefined roles

Use this option when the predefined SUSE Observability roles are a good fit but the external authentication provider has different names for the roles. For example when the LDAP authentication provider has similar but differently named roles include this YAML snippet in an authentication.yaml to give the roles from LDAP the same permissions and scopes as the predefined, equivalent, roles.

stackstate:
  authentication:
    roles:
      guest: ["ldap-guest-role"]
      powerUser: ["ldap-power-user-role"]
      admin: ["ldap-admin-role"]
      k8sTroubleshooter: ["ldap-troubleshooter-role"]
      platformAdmin: ["ldap-platform-admin-role"]

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

helm upgrade \
  --install \
  --namespace suse-observability \
  --values values.yaml \
  --values authentication.yaml \
suse-observability \
suse-observability/suse-observability

Custom roles with custom scopes and permissions via the configuration file

To set up a new role called development-troubleshooter, which will allow the same permissions as the predefined troubleshooter role, but only for the dev-test cluster, include this YAML snippet in an authentication.yaml:

stackstate:
  authentication:
    roles:
      custom:
        development-troubleshooter:
          systemPermissions:
          - access-cli
          - create-views
          - execute-component-actions
          - export-settings
          - manage-monitors
          - manage-notifications
          - manage-stackpacks
          - manage-star-view
          - perform-custom-query
          - read-agents
          - read-metrics
          - read-permissions
          - read-settings
          - read-system-notifications
          - read-telemetry-streams
          - read-traces
          - run-monitors
          - update-visualization
          - view-metric-bindings
          - view-monitors
          - view-notifications
          viewPermissions:
          - access-view
          - save-view
          - delete-view
          topologyScope: "label = 'kube_cluster_name:dev-test'" # Optional, leave out when the scope should be all topology

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

helm upgrade \
  --install \
  --namespace suse-observability \
  --values values.yaml \
  --values authentication.yaml \
suse-observability \
suse-observability/suse-observability

Custom roles via the CLI

To set up a new role called development-troubleshooter, which will allow the same permissions as the normal troubleshooter role, but only for the dev-test cluster, a new subject needs to be created. Further more this subject needs to be assigned the required set of permissions:

1. Create the subject (with the same name as the role, the role-subject matching is name based and case-sensitive):

   sts rbac create-subject --subject development-troubleshooter --scope 'label = "kube_cluster_name:dev-test"'

   Please note that when passing an topology query in a CLI command, all operators (like =, <,AND, and so on) need to be surrounded by spaces, as in the above example.

2. Configured subjects need permissions to access parts of the UI and to execute actions in it. To grant the same permissions as the troubleshooter role, follow the below example:

   # To grant permission to access any view use the special view name 'everything'
   sts rbac grant --subject development-troubleshooter --permission access-view --resource "everything"
   sts rbac grant --subject development-troubleshooter --permission save-view --resource "everything"
   sts rbac grant --subject development-troubleshooter --permission delete-view --resource "everything"
   
   sts rbac grant --subject development-troubleshooter --permission access-cli
   sts rbac grant --subject development-troubleshooter --permission create-views
   sts rbac grant --subject development-troubleshooter --permission execute-component-actions
   sts rbac grant --subject development-troubleshooter --permission export-settings
   sts rbac grant --subject development-troubleshooter --permission manage-monitors
   sts rbac grant --subject development-troubleshooter --permission manage-notifications
   sts rbac grant --subject development-troubleshooter --permission manage-stackpacks
   sts rbac grant --subject development-troubleshooter --permission manage-star-view
   sts rbac grant --subject development-troubleshooter --permission perform-custom-query
   sts rbac grant --subject development-troubleshooter --permission read-agents
   sts rbac grant --subject development-troubleshooter --permission read-metrics
   sts rbac grant --subject development-troubleshooter --permission read-permissions
   sts rbac grant --subject development-troubleshooter --permission read-settings
   sts rbac grant --subject development-troubleshooter --permission read-system-notifications
   sts rbac grant --subject development-troubleshooter --permission read-telemetry-streams
   sts rbac grant --subject development-troubleshooter --permission read-traces
   sts rbac grant --subject development-troubleshooter --permission run-monitors
   sts rbac grant --subject development-troubleshooter --permission update-visualization
   sts rbac grant --subject development-troubleshooter --permission view-metric-bindings
   sts rbac grant --subject development-troubleshooter --permission view-monitors
   sts rbac grant --subject development-troubleshooter --permission view-notifications

Please note that the subject's name, as well as permissions, are case-sensitive.
