# Couchbase

> Learn how to dynamically generate Couchbase Database user credentials.

The Infisical Couchbase dynamic secret allows you to generate Couchbase Cloud Database user credentials on demand based on configured roles and bucket access permissions.

## Prerequisite

Create an API Key in your Couchbase Cloud following the [official documentation](https://docs.couchbase.com/cloud/get-started/create-account.html#create-api-key).

<Info>The API Key must have permission to manage database users in your Couchbase Cloud organization and project.</Info>

  </Step>

  <Step title="Click 'Submit'">
    After submitting the form, you will see a dynamic secret created in the dashboard.

    <Note>

  </Step>

  <Step title="Generate dynamic secrets">
    Once you've successfully configured the dynamic secret, you're ready to generate on-demand credentials.
    To do this, simply click on the 'Generate' button which appears when hovering over the dynamic secret item.
    Alternatively, you can initiate the creation of a new lease by selecting 'New Lease' from the dynamic secret lease list section.

    <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-lease-empty.png" alt="Dynamic Secret" />

    When generating these secrets, it's important to specify a Time-to-Live (TTL) duration. This will dictate how long the credentials are valid for.

        <img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/provision-lease.png" alt="Provision Lease" />

    <Tip>
      Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret.
    </Tip>

    Once you click the `Submit` button, a new secret lease will be generated and the credentials for it will be shown to you.

  </Step>
</Steps>

## Advanced Bucket Configuration Examples

The advanced bucket configuration allows you to specify granular access control:

### Example 1: Specific Bucket Access

```json  theme={"dark"}
[
  {
    "name": "travel-sample"
  }
]
```

### Example 2: Bucket with Specific Scopes

```json  theme={"dark"}
[
  {
    "name": "travel-sample",
    "scopes": [
      {
        "name": "inventory"
      },
      {
        "name": "_default"
      }
    ]
  }
]
```

### Example 3: Bucket with Scopes and Collections

```json  theme={"dark"}
[
  {
    "name": "travel-sample",
    "scopes": [
      {
        "name": "inventory",
        "collections": ["airport", "airline"]
      },
      {
        "name": "_default",
        "collections": ["users"]
      }
    ]
  }
]
```

## Audit or Revoke Leases

Once you have created one or more leases, you will be able to access them by clicking on the respective dynamic secret item on the dashboard.
This will allow you to see the expiration time of the lease or delete a lease before its set time to live.

## Renew Leases

To extend the life of the generated dynamic secret leases past its initial time to live, simply click on the **Renew** button as illustrated below.
<img src="https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-lease-renew.png" alt="Provision Lease" />

<Warning>
  Lease renewals cannot exceed the maximum TTL set when configuring the dynamic secret
</Warning>

## Couchbase Roles and Permissions

The Couchbase dynamic secret integration supports the following database credential roles:

* **read**: Provides read-only access to bucket data
* **write**: Provides read and write access to bucket data

<Note>
  These roles are specifically for database credentials and are different from Couchbase's administrative roles. They provide data-level access to buckets, scopes, and collections based on your configuration.
</Note>

## Troubleshooting

### Common Issues

1. **Invalid API Key**: Ensure your Couchbase Cloud API key has the necessary permissions to manage database users
2. **Invalid Organization/Project/Cluster IDs**: Verify that the provided IDs exist and are accessible with your API key
3. **Role Permission Errors**: Make sure you're using only the supported database credential roles (read, write)
4. **Bucket Access Issues**: Ensure the specified buckets exist in your cluster and are accessible
