Configuring RBAC Policies

This topic describes how to use role-based access policies (RBAC) to grant or deny team members permissions to use Replicated services in the Replicated vendor portal.

About RBAC Policies​

By default, every team has two policies created automatically: Admin and Read Only. These default policies are not configurable.

You can configure custom RBAC policies if you are on the Enterprise pricing plan. Creating custom RBAC policies lets you limit which areas of the vendor portal are accessible to team members, and control read and read/write privileges to groups based on their role. For example, you can limit access for the sales team to one application and to specific channels.

You can also create custom RBAC policies in the vendor portal to manage user access and permissions in the Replicated collab repository in GitHub. For more information, see Managing Access to the Collab Repository.

Configure a Custom RBAC Policy​

To configure a custom RBAC policy:

  1. From the vendor portal Team page, select RBAC from the left menu.

  2. Do one of the following:

    • Click Create Policy from the RBAC page to create a new policy.

    • Click View policy to edit an existing custom policy in the list.

      important

      When you update an existing RBAC policy to add one or more team/support-issues resource, the GitHub role in the Replicated collab repository of every team member that is assigned to that policy and has a GitHub username saved in their account is updated accordingly.

  3. Edit the fields in the policy dialog. In the Definition pane, specify the allow and denied arrays in the resources key to create limits for the role.

    The default policy allows everything and the Config help pane displays any errors.

    Create RBAC Policy

  4. Click Create Policy to create a new policy, or click Update Policy to update an existing policy.

    note

    Click Cancel to exit without saving changes.

  5. To apply RBAC policies to vendor portal team members, you can:

Policy Definition​

A policy is defined in a single JSON document:

{
  "v1": {
    "name": "Read Only",
    "resources": {
      "allowed": [
        "**/read",
        "**/list"
      ],
      "denied": [
        "**/*"
      ]
    }
  }
}

The primary content of a policy document is the resources key. The resources key should contain two arrays, identified as allowed and denied. Resources specified in the allowed list are allowed for users assigned to the policy, and resources specified in the denied list are denied.

Resource names are hierarchical, and support wildcards and globs. For a complete list of resource names that can be defined in a policy document, see RBAC Resource Names.

When a policy document has conflicting rules, the behavior is predictable. For more information about conflicting rules, see Rule Order.

Policy Definition Example​

The following policy definition example limits any user with this role to viewing a specific application and a specific channel for that application:

```
{
  "v1": {
    "name": "Policy Name",
    "resources": {
      "allowed": [
        "kots/app/appID/list",
        "kots/app/appID/read",
        "kots/app/appID/channel/channelID/list",
        "kots/app/appID/channel/channelID/read"
      ],
      "denied": []
    }
  }
}
```

The example above uses an application ID and a channel ID to scope the permissions of the RBAC policy. To find your application and channel IDs, do the following:

  • To get the application ID, click Settings > Show Application ID (Advanced) in the vendor portal.

  • To get the channel ID, click Channels in the vendor portal. Then click the Release History link for the channel that you want to limit access to. The channel ID displays in your browser URL.

Rule Order​

When a resource name is specified in both the allow and the deny chains of a policy, defined rules determine which rule is applied.

If denied is left empty, it is implied as a **/* rule, unless **/* rule is specified in the allowed resources. If a rule exactly conflicts with another rule, the denied rule takes precedence.

Defining Precedence Using Rule Specificity​

The most specific rule definition is always applied, when compared with less specific rules. Specificity of a rule is calculated by the number of asterisks (** and *) in the definition. A ** in the rule definition is the least specific, followed by rules with *, and finally rules with no wildcards as the most specific.

Rule Order Examples​

In the following example, a policy grants access to promote releases to any channel except the Stable channel. It uses the rule pattern kots/app/[:appId]/channel/[:channelId]/promote. Note that you specify the channel ID, rather than the channel name. To find the channel ID, go to the vendor portal Channels page and click the Settings icon for the target channel.

{
  "v1": {
    "name": "No Access To Stable Channel",
    "resources": {
      "allowed": [
        "**/*"
      ],
      "denied": [
        "kots/app/*/channel/1eg7CyEofYSmVAnK0pEKUlv36Y3/promote"
      ]
    }
  }
}

In the following example, a policy grants access to viewing all customers, but not to creating releases, promoting releases, or creating new customers.

{
  "v1": {
    "name": "View Customers Only",
    "resources": {
      "allowed": [
        "kots/app/*/license/*/read",
        "kots/app/*/license/*/list",
        "kots/app/*/read",
        "kots/app/*/list"
      ],
      "denied": [
        "**/*"
      ]
    }
  }
}

Role-based Policy Examples​

Support Engineer​

The support engineer policy grants read access to release, channels, and application data, but read-write access to customer and license details. It also grants permission to open Replicated support issues and upload support bundles.

{
  "v1": {
    "name": "Support Engineer",
    "resources": {
      "allowed": [
        "**/read",
        "**/list",
        "kots/app/*/license/**",
        "team/support-issues/read",
        "team/support-issues/write"
      ],
      "denied": [
        "**/*"
      ]
    }
  }
}

Sales​

The sales policy grants read-write access to customers and license details and read-only access to resources necessary to manage licenses (applications, channels, and license fields). No additional access is granted.

{
  "v1": {
    "name": "Sales",
    "resources": {
      "allowed": [
        "kots/app/*/read",
        "kots/app/*/channel/*/read",
        "kots/app/*/licensefields/read",
        "kots/app/*/license/**"
      ],
      "denied": [
        "**/*"
      ]
    }
  }
}
