Tenants, like namespaces, can be managed using the [admin API](admin-api-overview.md). There are currently two configurable aspects of tenants:

* Admin roles
* Allowed clusters

## Tenant resources

### List

You can list all of the tenants associated with an [instance](reference-terminology.md#instance).

````mdx-code-block
<Tabs groupId="api-choice"
  defaultValue="pulsar-admin"
  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
<TabItem value="pulsar-admin">

Use the [`list`](/reference/#/@pulsar:version_reference@/pulsar-admin/tenants?id=list) subcommand.

```shell
pulsar-admin tenants list
```

Output:

```
my-tenant-1
my-tenant-2
```

</TabItem>
<TabItem value="REST API">

[](swagger:/admin/v2/TenantsBase_getTenants)

</TabItem>
<TabItem value="Java">

```java
admin.tenants().getTenants();
```

</TabItem>

</Tabs>
````

### Create

You can create a new tenant.

````mdx-code-block
<Tabs groupId="api-choice"
  defaultValue="pulsar-admin"
  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
<TabItem value="pulsar-admin">

Use the [`create`](/reference/#/@pulsar:version_reference@/pulsar-admin/tenants?id=create) subcommand:

```shell
pulsar-admin tenants create my-tenant
```

When creating a tenant, you can optionally assign admin roles using the `-r`/`--admin-roles`
flag, and clusters using the `-c`/`--allowed-clusters` flag. You can specify multiple values
as a comma-separated list. Here are some examples:

```shell
pulsar-admin tenants create my-tenant \
    --admin-roles role1,role2,role3 \
    --allowed-clusters cluster1
```

```shell
pulsar-admin tenants create my-tenant \
    -r role1 \
    -c cluster1
```

</TabItem>
<TabItem value="REST API">

[](swagger:/admin/v2/TenantsBase_createTenant)

</TabItem>
<TabItem value="Java">

```java
admin.tenants().createTenant(tenantName, tenantInfo);
```

</TabItem>

</Tabs>
````

### Get configuration

You can fetch the [configuration](reference-configuration.md) for an existing tenant at any time.

````mdx-code-block
<Tabs groupId="api-choice"
  defaultValue="pulsar-admin"
  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
<TabItem value="pulsar-admin">

Use the [`get`](/reference/#/@pulsar:version_reference@/pulsar-admin/tenants?id=get) subcommand and specify the name of the tenant. Here's an example:

```shell
pulsar-admin tenants get my-tenant
```

```json
{
  "adminRoles": [
    "admin1",
    "admin2"
  ],
  "allowedClusters": [
    "cl1",
    "cl2"
  ]
}
```

</TabItem>
<TabItem value="REST API">

[](swagger:/admin/v2/TenantsBase_getTenantAdmin)

</TabItem>
<TabItem value="Java">

```java
admin.tenants().getTenantInfo(tenantName);
```

</TabItem>

</Tabs>
````

### Delete

Tenants can be deleted from a Pulsar [instance](reference-terminology.md#instance).

````mdx-code-block
<Tabs groupId="api-choice"
  defaultValue="pulsar-admin"
  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
<TabItem value="pulsar-admin">

Use the [`delete`](/reference/#/@pulsar:version_reference@/pulsar-admin/tenants?id=delete) subcommand and specify the name of the tenant.

```shell
pulsar-admin tenants delete my-tenant
```

</TabItem>
<TabItem value="REST API">

[](swagger:/admin/v2/TenantsBase_deleteTenant)

</TabItem>
<TabItem value="Java">

```java
admin.Tenants().deleteTenant(tenantName);
```

</TabItem>

</Tabs>
````

### Update

You can update a tenant's configuration.

````mdx-code-block
<Tabs groupId="api-choice"
  defaultValue="pulsar-admin"
  values={[{"label":"pulsar-admin","value":"pulsar-admin"},{"label":"REST API","value":"REST API"},{"label":"Java","value":"Java"}]}>
<TabItem value="pulsar-admin">

Use the [`update`](/reference/#/@pulsar:version_reference@/pulsar-admin/tenants?id=update) subcommand.

```shell
pulsar-admin tenants update my-tenant \
    --admin-roles role1,role2 \
    --allowed-clusters cluster1,cluster2
```

</TabItem>
<TabItem value="REST API">

[](swagger:/admin/v2/TenantsBase_updateTenant)

</TabItem>
<TabItem value="Java">

```java
admin.tenants().updateTenant(tenantName, tenantInfo);
```

</TabItem>

</Tabs>
