Red Hat Developer Hub 1.4

Authorization

Configuring authorization by using role based access control (RBAC) in Red Hat Developer Hub

Red Hat Customer Content Services

Abstract

As a Red Hat Developer Hub platform engineer, you can manage authorizations of other users by using role based access control (RBAC) to meet the specific needs of your organization.

In Authentication, you learnt how to authenticate users to Red Hat Developer Hub. Developer Hub knowns who the users are.

In this book, learn how to authorize users to perform actions in Developer Hub. Define what users can do in Developer Hub.

Role-Based Access Control (RBAC) is a security concept that controls access to resources in a system, and specifies a mapping between users of the system, and the actions they can perform on resources in the system. You define roles with specific permissions, and then assign the roles to users and groups.

RBAC on Developer Hub is built on top of the Permissions framework, which defines RBAC policies in code. Rather than defining policies in code, the Developer Hub RBAC feature allows you to define policies in a declarative fashion using a simple CSV based format. You can define the policies by using Developer Hub web interface or REST API, rather than editing the CSV directly.

To define authorizations in Developer Hub:

  1. The Developer Hub administrator enables and gives access to the RBAC feature.

  2. You define your roles and policies by combining the following methods:

    • The Developer Hub policy administrator uses the Developer Hub web interface or REST API.
    • The Developer Hub administrator edits the main Developer Hub configuration file.
    • The Developer Hub administrator edits external files.

1. Enabling and giving access to the Role-Based Access Control (RBAC) feature

The Role-Based Access Control (RBAC) feature is disabled by default. Enable the RBAC plugin and declare policy administrators to start using RBAC features.

The permission policies for users and groups in the Developer Hub are managed by permission policy administrators. Only permission policy administrators can access the Role-Based Access Control REST API.

Prerequisites

Procedure

  1. The RBAC plugin is installed but disabled by default. To enable the ./dynamic-plugins/dist/backstage-community-plugin-rbac plugin, edit your dynamic-plugins.yaml with the following content.

    dynamic-plugins.yaml fragment

    plugins:
  - package: ./dynamic-plugins/dist/backstage-community-plugin-rbac
    disabled: false

    See Installing and viewing dynamic plugins.

  2. Declare policy administrators to enable a select number of authenticated users to configure RBAC policies through the REST API or Web UI, instead of modifying the CSV file directly. The permissions can be specified in a separate CSV file referenced in the app-config-rhdh ConfigMap, or permissions can be created using the REST API or Web UI.

    To declare users such as <your_policy_administrator_name> as policy administrators, edit your custom Developer Hub ConfigMap, such as app-config-rhdh, and add following code to the app-config.yaml content:

    app-config.yaml fragment

    permission:
  enabled: true
  rbac:
    admin:
      users:
        - name: user:default/<your_policy_administrator_name>

  3. In order for the Developer Hub Web UI to display available permissions provided by installed plugins, add the corresponding plugin IDs to your custom app-config.yaml Developer Hub configuration file.

    To display available permissions in RBAC UI, edit your custom Developer Hub ConfigMap, such as app-config-rhdh, and add following code to the app-config.yaml content:

    app-config.yaml fragment

    permission:
  enabled: true
  rbac:
    admin:
      users:
        - name: user:default/<your_policy_administrator_name>
    pluginsWithPermission:
      - catalog
      - scaffolder
      - permission

Verification

  1. Sign out from the existing Red Hat Developer Hub session and log in again using the declared policy administrator account.

  2. With RBAC enabled, most features are disabled by default.

    1. Navigate to the Catalog page in RHDH. The Create button is not visible. You cannot create new components.
    2. Navigate to the API page. The Register button is not visible.

Next steps

  • Explicitly enable permissions to resources in Developer Hub.

2. Determining permission policy and role configuration source

You can configure Red Hat Developer Hub policy and roles by using different sources. To maintain data consistency, Developer Hub associates each permission policy and role with one unique source. You can only use this source to change the resource.

The available sources are:

Configuration file

Configure roles and policies in the Developer Hub app-config.yaml configuration file, for instance to declare your policy administrators.

The Configuration file pertains to the default role:default/rbac_admin role provided by the RBAC plugin. The default role has limited permissions to create, read, update, delete permission policies or roles, and to read catalog entities.

Note

In case the default permissions are insufficient for your administrative requirements, you can create a custom admin role with the required permission policies.

REST API
Configure roles and policies by using the Developer Hub Web UI or by using the REST API.
CSV file
Configure roles and policies by using external CSV files.
Legacy

The legacy source applies to policies and roles defined before RBAC backend plugin version 2.1.3, and is the least restrictive among the source location options.

Important

Replace the permissions and roles using the legacy source with the permissions using the REST API or the CSV file sources.

Procedure

  • To determine the source of a role or policy, use a GET request.

3. Managing role-based access controls (RBAC) using the Red Hat Developer Hub Web UI

Policy administrators can use the Developer Hub web interface (Web UI) to allocate specific roles and permissions to individual users or groups. Allocating roles ensures that access to resources and functionalities is regulated across the Developer Hub.

With the policy administrator role in Developer Hub, you can assign permissions to users and groups. This role allows you to view, create, modify, and delete the roles using Developer Hub Web UI.

3.1. Creating a role in the Red Hat Developer Hub Web UI

You can create a role in the Red Hat Developer Hub using the Web UI.

Prerequisites

Procedure

  1. Go to Administration at the bottom of the sidebar in the Developer Hub.

    The RBAC tab appears, displaying all the created roles in the Developer Hub.

  2. (Optional) Click any role to view the role information on the OVERVIEW page.
  3. Click CREATE to create a role.
  4. Enter the name and description of the role in the given fields and click NEXT.
  5. Add users and groups using the search field, and click NEXT.
  6. Select Plugin and Permission from the drop-downs in the Add permission policies section.
  7. Select or clear the Policy that you want to set in the Add permission policies section, and click NEXT.
  8. Review the added information in the Review and create section.
  9. Click CREATE.

Verification

The created role appears in the list available in the RBAC tab.

3.2. Editing a role in the Red Hat Developer Hub Web UI

You can edit a role in the Red Hat Developer Hub using the Web UI.

Note

The policies generated from a policy.csv or ConfigMap file cannot be edited or deleted using the Developer Hub Web UI.

5. Managing authorizations by using external files

To automate Red Hat Developer Hub maintenance, you can configure permissions and roles in external files, before starting Developer Hub.

5.1. Defining authorizations in external files by using the operator

To automate Red Hat Developer Hub maintenance, you can define permissions and roles in external files, before starting Developer Hub. You need to prepare your files, upload them to your OpenShift Container Platform project, and configure Developer Hub to use the external files.

Prerequisites

Procedure

  1. Define your policies in a rbac-policies.csv CSV file by using the following format:

    1. Define role permissions: 

      p, <role_entity_reference>, <permission>, <action>, <allow_or_deny>
      <role_entity_reference>
      Role entity reference, such as: role:default/guest.
      <permission>

      Permission, such as: bulk.import, catalog.entity.read, or catalog.entity.refresh, or permission resource type, such as: bulk-import or catalog-entity.

      See: Permission policies reference.

      <action>
      Action type, such as: use, read, create, update, delete.
      <allow_or_deny>
      Access granted: allow or deny.

    2. Assign the role to a group or a user: 

      g, <group_or_user>, <role_entity_reference>
      <group_or_user>

      Group, such as: user:default/mygroup, or user, such as: user:default/myuser.

      Sample rbac-policies.csv

      p, role:default/guests, catalog-entity, read, allow
p, role:default/guests, catalog.entity.create, create, allow
g, user:default/my-user, role:default/guests
g, group:default/my-group, role:default/guests

  2. Define your conditional policies in a rbac-conditional-policies.yaml YAML file by using the following format: 

    result: CONDITIONAL
roleEntityRef: <role_entity_reference>
pluginId: <plugin_id>
permissionMapping:
  - read
  - update
  - delete
conditions: <conditions>

    See: Conditional policies reference.

  3. Upload your rbac-policies.csv and rbac-conditional-policies.yaml files to a rbac-policies config map in your OpenShift Container Platform project containing Developer Hub. 

    $ oc create configmap rbac-policies \
     --from-file=rbac-policies.csv \
     --from-file=rbac-conditional-policies.yaml

  4. Update your Developer Hub Backstage custom resource to mount in the Developer Hub filesystem your files from the rbac-policies config map:

    Backstage Custom resource fragment

    apiVersion: rhdh.redhat.com/v1alpha3
kind: Backstage
spec:
  application:
    extraFiles:
      mountPath: /opt/app-root/src
      configMaps:
        - name: rbac-policies

  5. Update your Developer Hub app-config.yaml configuration file to use the rbac-policies.csv and rbac-conditional-policies.yaml external files:

    app-config.yml fragment

    permission:
  enabled: true
  rbac:
    conditionalPoliciesFile: /opt/app-root/src/rbac-conditional-policies.yaml
    policies-csv-file: /opt/app-root/src/rbac-policies.csv
    policyFileReload: true

5.2. Defining authorizations in external files by using Helm

To automate Red Hat Developer Hub maintenance, you can define permissions and roles in external files, before starting Developer Hub. You need to prepare your files, upload them to your OpenShift Container Platform project, and configure Developer Hub to use the external files.

Prerequisites

Procedure

  1. Define your policies in a rbac-policies.csv CSV file by using the following format:

    1. Define role permissions: 

      p, <role_entity_reference>, <permission>, <action>, <allow_or_deny>
      <role_entity_reference>
      Role entity reference, such as: role:default/guest.
      <permission>

      Permission, such as: bulk.import, catalog.entity.read, or catalog.entity.refresh, or permission resource type, such as: bulk-import or catalog-entity.

      See: Permission policies reference.

      <action>
      Action type, such as: use, read, create, update, delete.
      <allow_or_deny>
      Access granted: allow or deny.

    2. Assign the role to a group or a user: 

      g, <group_or_user>, <role_entity_reference>
      <group_or_user>

      Group, such as: user:default/mygroup, or user, such as: user:default/myuser.

      Sample rbac-policies.csv

      p, role:default/guests, catalog-entity, read, allow
p, role:default/guests, catalog.entity.create, create, allow
g, user:default/my-user, role:default/guests
g, group:default/my-group, role:default/guests

  2. Define your conditional policies in a rbac-conditional-policies.yaml YAML file by using the following format: 

    result: CONDITIONAL
roleEntityRef: <role_entity_reference>
pluginId: <plugin_id>
permissionMapping:
  - read
  - update
  - delete
conditions: <conditions>

    See: Conditional policies reference.

  3. Upload your rbac-policies.csv and rbac-conditional-policies.yaml files to a rbac-policies config map in your OpenShift Container Platform project containing Developer Hub. 

    $ oc create configmap rbac-policies \
     --from-file=rbac-policies.csv \
     --from-file=rbac-conditional-policies.yaml

  4. Update your Developer Hub Backstage Helm chart to mount in the Developer Hub filesystem your files from the rbac-policies config map:

    1. In the Developer Hub Helm Chart, go to Root Schema → Backstage chart schema → Backstage parameters → Backstage container additional volume mounts.

    2. Select Add Backstage container additional volume mounts and add the following values:

      mountPath
      /opt/app-root/src
      Name
      rbac-policies

    3. Add the RBAC policy to the Backstage container additional volumes in the Developer Hub Helm Chart:

      name
      rbac-policies
      configMap
      defaultMode
      420
      name
      rbac-policies

  5. Update your Developer Hub app-config.yaml configuration file to use the rbac-policies.csv and rbac-conditional-policies.yaml external files:

    app-config.yml fragment

    permission:
  enabled: true
  rbac:
    conditionalPoliciesFile: /opt/app-root/src/rbac-conditional-policies.yaml
    policies-csv-file: /opt/app-root/src/rbac-policies.csv
    policyFileReload: true

6. Permission policies reference

Permission policies in Red Hat Developer Hub are a set of rules to govern access to resources or functionalities. These policies state the authorization level that is granted to users based on their roles. The permission policies are implemented to maintain security and confidentiality within a given environment.

You can define the following types of permissions in Developer Hub:

  • resource type
  • basic

The distinction between the two permission types depends on whether a permission includes a defined resource type.

You can define the resource type permission using either the associated resource type or the permission name as shown in the following example:

Example resource type permission definition

p, role:default/myrole, catalog.entity.read, read, allow
g, user:default/myuser, role:default/myrole

p, role:default/another-role, catalog-entity, read, allow
g, user:default/another-user, role:default/another-role

You can define the basic permission in Developer Hub using the permission name as shown in the following example:

Example basic permission definition

p, role:default/myrole, catalog.entity.create, create, allow
g, user:default/myuser, role:default/myrole

Developer Hub supports following permission policies:

Kubernetes permissions
.Kubernetes permissions
NameResource typePolicyDescription

kubernetes.proxy

 

use

OCM permissions
Basic OCM permissions only restrict access to the cluster view, but they do not prevent access to the Kubernetes clusters in the resource view. For more effective permissions, consider applying a conditional policy to restrict access to catalog entities that are of type kubernetes-cluster. Access restriction is dependent on the set of permissions granted to a role. For example, if the role had full permissions (read, update, and delete), then you must specify all its permissions in the permissionMapping field.

Example permissionMapping definition

result: CONDITIONAL
roleEntityRef: 'role:default/<YOUR_ROLE>'
pluginId: catalog
resourceType: catalog-entity
permissionMapping:
  - read
  - update
  - delete
conditions:
  not:
    rule: HAS_SPEC

7. Conditional policies in Red Hat Developer Hub

The permission framework in Red Hat Developer Hub provides conditions, supported by the RBAC backend plugin (backstage-plugin-rbac-backend). The conditions work as content filters for the Developer Hub resources that are provided by the RBAC backend plugin.

The RBAC backend API stores conditions assigned to roles in the database. When you request to access the frontend resources, the RBAC backend API searches for the corresponding conditions and delegates them to the appropriate plugin using its plugin ID. If you are assigned to multiple roles with different conditions, then the RBAC backend merges the conditions using the anyOf criteria.

Conditional criteria

A condition in Developer Hub is a simple condition with a rule and parameters. However, a condition can also contain a parameter or an array of parameters combined by conditional criteria. The supported conditional criteria includes:

  • allOf: Ensures that all conditions within the array must be true for the combined condition to be satisfied.
  • anyOf: Ensures that at least one of the conditions within the array must be true for the combined condition to be satisfied.
  • not: Ensures that the condition within it must not be true for the combined condition to be satisfied.
Conditional object

The plugin specifies the parameters supported for conditions. You can access the conditional object schema from the RBAC API endpoint to understand how to construct a conditional JSON object, which is then used by the RBAC backend plugin API.

A conditional object contains the following parameters:

Table 10. Conditional object parameters

ParameterTypeDescription

result

String

Always has the value CONDITIONAL

roleEntityRef

String

String entity reference to the RBAC role, such as role:default/dev

pluginId

String

Corresponding plugin ID, such as catalog

permissionMapping

String array

Array permission actions, such as ['read', 'update', 'delete']

resourceType

String

Resource type provided by the plugin, such as catalog-entity

conditions

JSON

Condition JSON with parameters or array parameters joined by criteria

Conditional policy aliases

The RBAC backend plugin (backstage-plugin-rbac-backend) supports the use of aliases in conditional policy rule parameters. The conditional policy aliases are dynamically replaced with the corresponding values during policy evaluation. Each alias in conditional policy is prefixed with a $ sign indicating its special function.

The supported conditional aliases include:

  • $currentUser: This alias is replaced with the user entity reference for the user who requests access to the resource. For example, if user Tom from the default namespace requests access, $currentUser becomes user:default/tom.

Example conditional policy object with $currentUser alias

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/developer",
  "pluginId": "catalog",
  "resourceType": "catalog-entity",
  "permissionMapping": ["delete"],
  "conditions": {
    "rule": "IS_ENTITY_OWNER",
    "resourceType": "catalog-entity",
    "params": {
      "claims": ["$currentUser"]
    }
  }
}

  • $ownerRefs: This alias is replaced with ownership references, usually as an array that includes the user entity reference and the user’s parent group entity reference. For example, for user Tom from team-a, $ownerRefs becomes ['user:default/tom', 'group:default/team-a'].

Example conditional policy object with $ownerRefs alias

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/developer",
  "pluginId": "catalog",
  "resourceType": "catalog-entity",
  "permissionMapping": ["delete"],
  "conditions": {
    "rule": "IS_ENTITY_OWNER",
    "resourceType": "catalog-entity",
    "params": {
      "claims": ["$ownerRefs"]
    }
  }
}

7.1. Conditional policies reference

You can access API endpoints for conditional policies in Red Hat Developer Hub. For example, to retrieve the available conditional rules, which can help you define these policies, you can access the GET [api/plugins/condition-rules] endpoint.

The api/plugins/condition-rules returns the condition parameters schemas, for example: 

[
   {
      "pluginId": "catalog",
      "rules": [
         {

The RBAC backend API constructs a condition JSON object based on the previous condition schema.

7.1.1. Examples of conditional policies

In Red Hat Developer Hub, you can define conditional policies with or without criteria. You can use the following examples to define the conditions based on your use case:

A condition without criteria

Consider a condition without criteria displaying catalogs only if user is a member of the owner group. To add this condition, you can use the catalog plugin schema IS_ENTITY_OWNER as follows:

Example condition without criteria

{
  "rule": "IS_ENTITY_OWNER",
  "resourceType": "catalog-entity",
  "params": {
    "claims": ["group:default/team-a"]
  }
}

In the previous example, the only conditional parameter used is claims, which contains a list of user or group entity references.

You can apply the previous example condition to the RBAC REST API by adding additional parameters as follows: 

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/test",
  "pluginId": "catalog",
  "resourceType": "catalog-entity",
  "permissionMapping": ["read"],
  "conditions": {
    "rule": "IS_ENTITY_OWNER",
    "resourceType": "catalog-entity",
    "params": {
      "claims": ["group:default/team-a"]
    }
  }
}
A condition with criteria

Consider a condition with criteria, which displays catalogs only if user is a member of owner group OR displays list of all catalog user groups.

To add the criteria, you can add another rule as IS_ENTITY_KIND in the condition as follows:

Example condition with criteria

{
  "anyOf": [
    {
      "rule": "IS_ENTITY_OWNER",
      "resourceType": "catalog-entity",
      "params": {
        "claims": ["group:default/team-a"]
      }
    },
    {
      "rule": "IS_ENTITY_KIND",
      "resourceType": "catalog-entity",
      "params": {
        "kinds": ["Group"]
      }
    }
  ]
}

Note

Running conditions in parallel during creation is not supported. Therefore, consider defining nested conditional policies based on the available criteria.

Example of nested conditions

{
  "anyOf": [
    {
      "rule": "IS_ENTITY_OWNER",
      "resourceType": "catalog-entity",
      "params": {
        "claims": ["group:default/team-a"]
      }
    },
    {
      "rule": "IS_ENTITY_KIND",
      "resourceType": "catalog-entity",
      "params": {
        "kinds": ["Group"]
      }
    }
  ],
  "not": {
    "rule": "IS_ENTITY_KIND",
    "resourceType": "catalog-entity",
    "params": { "kinds": ["Api"] }
  }
}

You can apply the previous example condition to the RBAC REST API by adding additional parameters as follows: 

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/test",
  "pluginId": "catalog",
  "resourceType": "catalog-entity",
  "permissionMapping": ["read"],
  "conditions": {
    "anyOf": [
      {
        "rule": "IS_ENTITY_OWNER",
        "resourceType": "catalog-entity",
        "params": {
          "claims": ["group:default/team-a"]
        }
      },
      {
        "rule": "IS_ENTITY_KIND",
        "resourceType": "catalog-entity",
        "params": {
          "kinds": ["Group"]
        }
      }
    ]
  }
}

The following examples can be used with Developer Hub plugins. These examples can help you determine how to define conditional policies:

Conditional policy defined for Keycloak plugin

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/developer",
  "pluginId": "catalog",
  "resourceType": "catalog-entity",
  "permissionMapping": ["update", "delete"],
  "conditions": {
    "not": {
      "rule": "HAS_ANNOTATION",
      "resourceType": "catalog-entity",
      "params": { "annotation": "keycloak.org/realm", "value": "<YOUR_REALM>" }
    }
  }
}

The previous example of Keycloak plugin prevents users in the role:default/developer from updating or deleting users that are ingested into the catalog from the Keycloak plugin.

Note

In the previous example, the annotation keycloak.org/realm requires the value of <YOUR_REALM>.

Conditional policy defined for Quay plugin

{
  "result": "CONDITIONAL",
  "roleEntityRef": "role:default/developer",
  "pluginId": "scaffolder",
  "resourceType": "scaffolder-action",
  "permissionMapping": ["use"],
  "conditions": {
    "not": {
      "rule": "HAS_ACTION_ID",
      "resourceType": "scaffolder-action",
      "params": { "actionId": "quay:create-repository" }
    }
  }
}

The previous example of Quay plugin prevents the role role:default/developer from using the Quay scaffolder action. Note that permissionMapping contains use, signifying that scaffolder-action resource type permission does not have a permission policy.

For more information about permissions in Red Hat Developer Hub, see Section 6, “Permission policies reference”.

8. User statistics in Red Hat Developer Hub

In Red Hat Developer Hub, the licensed-users-info-backend plugin provides statistical information about the logged-in users using the Web UI or REST API endpoints.

The licensed-users-info-backend plugin enables administrators to monitor the number of active users on Developer Hub. Using this feature, organizations can compare their actual usage with the number of licenses they have purchased. Additionally, you can share the user metrics with Red Hat for transparency and accurate licensing.

The licensed-users-info-backend plugin is enabled by default. This plugin enables a Download User List link at the bottom of the Administration → RBAC tab.

8.1. Downloading active users list in Red Hat Developer Hub

You can download the list of users in CSV format using the Developer Hub web interface.
