core/v2/roles

NOTE: Requests to core/v2/roles API endpoints require you to authenticate with a Sensu API key or access token. The code examples in this document use the environment variable $SENSU_API_KEY to represent a valid API key in API requests.

Get all roles

The /roles API endpoint provides HTTP GET access to role data.

Example

The following example demonstrates a GET request to the /roles API endpoint:

curl -X GET \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles \
-H "Authorization: Key $SENSU_API_KEY"

The request results in a successful HTTP/1.1 200 OK response and a JSON array that contains the role definitions in the default namespace:

[
  {
    "rules": [
      {
        "verbs": [
          "get",
          "list"
        ],
        "resources": [
          "events"
        ],
        "resource_names": null
      }
    ],
    "metadata": {
      "name": "event-reader",
      "namespace": "default",
      :created_by": "admin"
    }
  },
  {
    "rules": [
      {
        "verbs": [
          "get"
        ],
        "resources": [
          "*"
        ],
        "resource_names": null
      }
    ],
    "metadata": {
      "name": "read-only",
      "namespace": "default",
      "created_by": "admin"
    }
  }
]

Create a new role

The /roles API endpoint provides HTTP POST access to create Sensu roles.

Example

In the following example, an HTTP POST request is submitted to the /roles API endpoint to create a role named event-reader:

curl -X POST \
-H "Authorization: Key $SENSU_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
  "rules": [
    {
      "verbs": [
        "get",
        "list"
      ],
      "resources": [
        "events"

      "resource_names": []
    }
  ],

    "name": "event-reader",
    "namespace": "default"
  }
}' \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles

The request will return a successful HTTP/1.1 201 Created response.

API Specification

/roles (POST)
description Creates a Sensu role.
example URL http://hostname:8080/api/core/v2/namespaces/default/roles

Get a specific role

The /roles/:role API endpoint provides HTTP GET access to role data for specific :role definitions, by role name.

Example

The following example queries the /roles/:role API endpoint for the :role named read-only:

curl -X GET \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles/read-only \
-H "Authorization: Key $SENSU_API_KEY"

The request will return a successful HTTP/1.1 200 OK response and a JSON map that contains the requested :role definition (in this example, read-only):

{
  "rules": [
    {
      "verbs": [
        "read"
      ],
      "resources": [
        "*"
      ],
      "resource_names": null
    }
  ],
  "metadata": {

      ],
      "resource_names": null
    }
  ],
  "metadata": {
    "name": "read-only",
    "namespace": "default",
    "created_by": "admin"
  }
}

Create or update a role

The /roles/:role API endpoint provides HTTP PUT access to create or update specific :role definitions, by role name.

Example

In the following example, an HTTP PUT request is submitted to the /roles/:role API endpoint to create the role read-only:

curl -X PUT \
-H "Authorization: Key $SENSU_API_KEY" \
-H 'Content-Type: application/json' \
-d '{
  "rules": [
    {
      "verbs": [
        "read"
      ],
      "resources": [
        "*"
      ],
      "resource_names": null
    }
  ],
  "metadata": {
    "name": "read-only",
    "namespace": "default"
  }
}' \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles/read-only

The request will return a successful HTTP/1.1 201 Created response.

API Specification

/roles/:role (PUT)
description Creates or updates the specified Sensu role.
example URL http://hostname:8080/api/core/v2/namespaces/default/roles/event-reader
payload 
{
  "rules": [
    {
      "verbs": [
        "read"
      ],
      "resources": [
        "*"

    "name": "read-only",
    "namespace": "default"
  }
}
response codes
  • Success: 201 (Created)
  • Malformed: 400 (Bad Request)
  • Error: 500 (Internal Server Error)

Update a role with PATCH

The /roles/:role API endpoint provides HTTP PATCH access to update :role definitions, specified by role name.

NOTE: You cannot change a resource’s name or namespace with a PATCH request. Use a PUT request instead.

Also, you cannot add elements to an array with a PATCH request — you must replace the entire array.

Example

In the following example, an HTTP PATCH request is submitted to the /roles/:role API endpoint to update the verbs array within the rules array for the global-event-admin role, resulting in an HTTP/1.1 200 OK response and the updated role definition.

We support JSON merge patches, so you must set the Content-Type header to application/merge-patch+json for PATCH requests.

curl -X PATCH \
-H "Authorization: Key $SENSU_API_KEY" \
-H 'Content-Type: application/merge-patch+json' \
-d '{
  "rules": [
    {
      "verbs": [
        "get",
        "list"
      ],
      "resources": [
        "events"
      ],
      "resource_names": null
    }
  ]
}' \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles/event-reader

API Specification

/roles/:role (PATCH)
description Updates the specified Sensu role.
example URL http://hostname:8080/api/core/v2/namespaces/default/roles/event-reader
payload 
{
  "rules": [
    {
      "verbs": [
        "get",
        "list"
      ],
      "resources": [
        "events"
      ],
      "resource_names": null
    }
  ]
}
response codes
  • Success: 200 (OK)
  • Malformed: 400 (Bad Request)
  • Error: 500 (Internal Server Error)

Delete a role

The /roles/:role API endpoint provides HTTP DELETE access to delete a role from Sensu (specified by the role name).

Example

The following example shows a request to the /roles/:role API endpoint to delete the role read-only, resulting in a successful HTTP/1.1 204 No Content response:

curl -X DELETE \
http://127.0.0.1:8080/api/core/v2/namespaces/default/roles/read-only \
-H "Authorization: Key $SENSU_API_KEY"

API Specification

/roles/:role (DELETE)
description Removes the specified role from Sensu.
example url http://hostname:8080/api/core/v2/namespaces/default/roles/read-only
response codes
  • Success: 204 (No Content)
  • Missing: 404 (Not Found)
  • Error: 500 (Internal Server Error)

Get a subset of roles with response filtering

The /roles API endpoint supports response filtering for a subset of role data based on labels and the following fields:

  • role.name
  • role.namespace

Example

The following example demonstrates a request to the /roles API endpoint with response filtering for only role definitions that are in the development namespace:

curl -H "Authorization: Key $SENSU_API_KEY" http://127.0.0.1:8080/api/core/v2/roles -G \
--data-urlencode 'fieldSelector=role.namespace == development'

The example request will result in a successful HTTP/1.1 200 OK response and a JSON array that contains only role definitions in the development namespace:

[
  {
    "rules": [
      {
        "verbs": [
          "get",
          "list",
          "create",
          "update",
          "delete"
        ],
        "resources": [
          "*"
        ],
        "resource_names": null
      }
    ],
    "metadata": {
      "name": "admin_role",
      "namespace": "development",
      "created_by": "admin"
    }
  },
  {
    "rules": [
      {
        "verbs": [
          "get",
          "list",
          "create",
          "update",
          "delete"
        ],
        "resources": [
          "assets",
          "checks",
          "entities",
          "events",
          "filters",
          "handlers",
          "hooks",
          "mutators",
          "pipelines",
          "rolebindings",
          "roles",
          "silenced"
        ],
        "resource_names": null
      }
    ],
    "metadata": {
      "name": "namespaced-resources-all-verbs",
      "namespace": "development",
      "created_by": "admin"
    }
  },
  {
    "rules": [
      {
        "verbs": [
          "get",
          "list"
        ],
        "resources": [
          "events"
        ],
        "resource_names": null
      }
    ],
    "metadata": {
      "name": "system:pipeline",
      "namespace": "development"
    }
  }
]
