Chapter 3. Permission policies in Red Hat Developer Hub

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 depend 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

The following permission policies are supported in the Developer Hub:

Catalog permissions

`catalog.entity.read`	`catalog-entity`	read	Allows user or role to read from the catalog
`catalog.entity.create`		create	Allows user or role to create catalog entities, including registering an existing component in the catalog

3.1. Permission policies configuration

There are two approaches to configure the permission policies in Red Hat Developer Hub, including:

Configuration of permission policies administrators
Configuration of permission policies defined in an external file

3.1.1. Configuration of permission policies defined in an external file

You can configure the permission policies before starting the Red Hat Developer Hub. If permission policies are defined in an external file, then you can import the same file in the Developer Hub. You must define the permission policies using the following Casbin rules format:

---
`p, <ROLE>, <PERMISSION_NAME or PERMISSION_RESOURCE_TYPE>, <PERMISSION_POLICY_ACTION>, <ALLOW or DENY>`
---

You can define roles using the following Casbin rules format:

---
`g, <USER or GROUP>, <ROLE>`
---

Note

For information about the Casbin rules format, see Basics of Casbin rules.

The following is an example of permission policies configuration:

---
`p, role:default/guests, catalog-entity, read, allow`

p, role:default/guests, catalog.entity.create, create, allow

g, user:default/<USER_TO_ROLE>, role:default/guests

g, group:default/<GROUP_TO_ROLE>, role:default/guests ---

If a defined permission does not contain an action associated with it, then add use as a policy. See the following example:

---
`p, role:default/guests, kubernetes.proxy, use, allow`
---

You can define the policy.csv file path in the app-config.yaml file:

permission:
  enabled: true
  rbac:
    policies-csv-file: /some/path/rbac-policy.csv

You can use an optional configuration value that enables reloading the CSV file without restarting the Developer Hub instance.

Set the value of the policyFileReload option in the app-config.yaml file:

# ...
permission:
  enabled: true
  rbac:
    policies-csv-file: /some/path/rbac-policy.csv
    policyFileReload: true
    # ...

3.1.1.1. Mounting `policy.csv` file using the Developer Hub Operator

When the Red Hat Developer Hub is deployed with the Operator, you can add your policy.csv file using the Developer Hub Operator by creating a ConfigMap and mounting it through your Custom Resource (CR).

Prerequisites

You are logged in to your OpenShift Container Platform account using the OpenShift Container Platform web console.
Red Hat Developer Hub is installed and deployed using the Operator.
You have added a custom configuration file to OpenShift Container Platform. For more information, see Adding a custom configuration file to OpenShift Container Platform.
For more information, see Installing Red Hat Developer Hub on OpenShift Container Platform with the Operator.

Procedure

In OpenShift Container Platform, create a ConfigMap to hold the policies as shown in the following example:

Example ConfigMap

kind: ConfigMap
apiVersion: v1
metadata:
  name: rbac-policy
data:
  rbac-policy.csv: |
    p, role:default/guests, catalog-entity, read, allow
    p, role:default/guests, catalog.entity.create, create, allow

    g, user:default/<YOUR_USER>, role:default/guests

Update the policy path in your custom app-config.yaml ConfigMap as follows:
Example app-config.yaml file
```
permission:
  enabled: true
  rbac:
    policies-csv-file: ./rbac-policy.csv
```
From the Developer perspective in the OpenShift Container Platform web console, select the Topology view.
Click the overflow menu for the Red Hat Developer Hub instance that you want to use and select Edit Backstage to load the YAML view of the Red Hat Developer Hub instance.

In the CR, enter the name of the custom rbac-policy ConfigMap as the value for the spec.application.extraFiles.configMaps field. For example:

Example custom resource

apiVersion: rhdh.redhat.com/v1alpha1
kind: Backstage
metadata:
  name: example
spec:
  application:
    appConfig:
      mountPath: /opt/app-root/src
      configMaps:
        - name: app-config-rhdh
    extraEnvs:
      secrets:
        - name: secrets-rhdh
    extraFiles:
      mountPath: /opt/app-root/src
      configMaps:
        - name: rbac-policy
    replicas: 1
    route:
      enabled: true
  database:
    enableLocalDb: true

Click Save.

Verification

Navigate back to the Topology view and wait for the Red Hat Developer Hub pod to start.
Click the Open URL icon to access the Red Hat Developer Hub platform with the updated configuration settings.

3.1.1.2. Mounting `policy.csv` file to the Developer Hub Helm chart

When the Red Hat Developer Hub is deployed with the Helm chart, you must define the policy.csv file by mounting it to the Developer Hub Helm chart.

You can add your policy.csv file to the Developer Hub Helm Chart by creating a configMap and mounting it.

Prerequisites

You are logged in to your OpenShift Container Platform account using the OpenShift Container Platform web console.
Red Hat Developer Hub is installed and deployed using Helm Chart.
For more information, see Installing Red Hat Developer Hub on OpenShift Container Platform with the Helm chart.

Procedure

In OpenShift Container Platform, create a ConfigMap to hold the policies as shown in the following example:

Example ConfigMap

kind: ConfigMap
apiVersion: v1
metadata:
  name: rbac-policy
  namespace: rhdh
data:
  rbac-policy.csv: |
    p, role:default/guests, catalog-entity, read, allow
    p, role:default/guests, catalog.entity.create, create, allow

    g, user:default/<YOUR_USER>, role:default/guests

In the Developer Hub Helm Chart, go to Root Schema Backstage chart schema Backstage parameters Backstage container additional volume mounts.
Select Add Backstage container additional volume mounts and add the following values:
- mountPath: opt/app-root/src/rbac
- Name: rbac-policy
Add the RBAC policy to the Backstage container additional volumes in the Developer Hub Helm Chart:
- name: rbac-policy
- configMap
  - defaultMode: 420
  - name: rbac-policy
Update the policy path in the app-config.yaml file as follows:
Example app-config.yaml file
```
permission:
  enabled: true
  rbac:
    policies-csv-file: ./rbac/rbac-policy.csv
```
