Multi-tenancy configuration

Multi-tenancy is enabled by default, but you can disable it or change its settings using config/opensearch-security/config.yml:

config:
  dynamic:
    kibana:
      multitenancy_enabled: true
      server_username: kibanaserver
      index: '.kibana'
    do_not_fail_on_forbidden: false
Setting Description
multitenancy_enabled Enable or disable multi-tenancy. Default is true.
server_username Must match the name of the OpenSearch Dashboards server user from opensearch_dashboards.yml. Default is kibanaserver.
index Must match the name of the OpenSearch Dashboards index from opensearch_dashboards.yml. Default is .kibana.
do_not_fail_on_forbidden If true, the security plugin removes any content that a user is not allowed to see from search results. If false, the plugin returns a security exception. Default is false.

opensearch_dashboards.yml has some additional settings:

opensearch.username: kibanaserver
opensearch.password: kibanaserver
opensearch.requestHeadersAllowlist: ["securitytenant","Authorization"]
opensearch_security.multitenancy.enabled: true
opensearch_security.multitenancy.tenants.enable_global: true
opensearch_security.multitenancy.tenants.enable_private: true
opensearch_security.multitenancy.tenants.preferred: ["Private", "Global"]
opensearch_security.multitenancy.enable_filter: false
Setting Description
opensearch.requestHeadersAllowlist OpenSearch Dashboards requires that you add all HTTP headers to the allow list so that the headers pass to OpenSearch. Multi-tenancy uses a specific header, securitytenant, that must be present with the standard Authorization header. If the securitytenant header is not on the allow list, OpenSearch Dashboards starts with a red status.
opensearch_security.multitenancy.enabled Enables or disables multi-tenancy in OpenSearch Dashboards. Default is true.
opensearch_security.multitenancy.tenants.enable_global Enables or disables the global tenant. Default is true.
opensearch_security.multitenancy.tenants.enable_private Enables or disables the private tenant. Default is true.
opensearch_security.multitenancy.tenants.preferred Lets you change ordering in the Tenants tab of OpenSearch Dashboards. By default, the list starts with global and private (if enabled) and then proceeds alphabetically. You can add tenants here to move them to the top of the list.
opensearch_security.multitenancy.enable_filter If you have many tenants, you can add a search bar to the top of the list. Default is false.

Add tenants

To create tenants, use OpenSearch Dashboards, the REST API, or tenants.yml.

OpenSearch Dashboards

  1. Open OpenSearch Dashboards.
  2. Choose Security, Tenants, and Create tenant.
  3. Give the tenant a name and description.
  4. Choose Create.

REST API

See Create tenant.

tenants.yml

---
_meta:
  type: "tenants"
  config_version: 2

## Demo tenants
admin_tenant:
  reserved: false
  description: "Demo tenant for admin user"

Give roles access to tenants

After creating a tenant, give a role access to it using OpenSearch Dashboards, the REST API, or roles.yml.

  • Read-write (kibana_all_write) permissions let the role view and modify objects in the tenant.
  • Read-only (kibana_all_read) permissions let the role view objects, but not modify them.

OpenSearch Dashboards

  1. Open OpenSearch Dashboards.
  2. Choose Security, Roles, and a role.
  3. For Tenant permissions, add tenants, press Enter, and give the role read and/or write permissions to it.

REST API

See Create role.

roles.yml

---
test-role:
  reserved: false
  hidden: false
  cluster_permissions:
  - "cluster_composite_ops"
  - "indices_monitor"
  index_permissions:

Manage OpenSearch Dashboards indices

The open source version of OpenSearch Dashboards saves all objects to a single index: .kibana. The Security plugin uses this index for the global tenant, but separate indices for every other tenant. Each user also has a private tenant, so you might see a large number of indices that follow two patterns:

.kibana_<hash>_<tenant_name>
.kibana_<hash>_<username>

The Security plugin scrubs these index names of special characters, so they might not be a perfect match of tenant names and usernames.

To back up your OpenSearch Dashboards data, take a snapshot of all tenant indexes using an index pattern such as .kibana*.
