# AWS ElastiCache dynamic secrets

> Learn how to dynamically generate AWS ElastiCache user credentials.

The Infisical AWS ElastiCache dynamic secret allows you to generate AWS ElastiCache credentials on demand based on configured role.

## Prerequisites

2. Create an AWS IAM user with the following permissions:

```json theme={"dark"}
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Action": [
        "elasticache:DescribeUsers",
        "elasticache:ModifyUser",
        "elasticache:CreateUser",
        "elasticache:CreateUserGroup",
        "elasticache:DeleteUser",
        "elasticache:DescribeReplicationGroups",
        "elasticache:DescribeUserGroups",
        "elasticache:ModifyReplicationGroup",
        "elasticache:ModifyUserGroup"
      ],
      "Resource": "arn:aws:elasticache:<region>:<account-id>:user:*"
    }
  ]
}
```

3. Create an access key ID and secret access key for the user you created in the previous step. You'll need these to configure the Infisical dynamic secret.

> [!NOTE]
>
> New leases may take up-to a couple of minutes before ElastiCache has the chance to complete their configuration.
> It's recommended to use a retry strategy when establishing new ElastiCache connections.
> This may prevent errors when trying to use a password that isn't yet live on the targeted ElastiCache cluster.
>
> While a leasing is being created, you'll be unable to create new leases for the same dynamic secret.

> [!NOTE]
>
> Please ensure that your ElastiCache cluster has transit encryption enabled and set to required. This is required for the dynamic secret to work.

## Set up dynamic secrets with AWS ElastiCache

**1. Open Secret Overview Dashboard**

Open the Secret Overview dashboard and select the environment in which you would like to add a dynamic secret.

**2. Click on the 'Add Dynamic Secret' button**

**3. Select AWS ElastiCache**

![Dynamic Secret Modal](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-modal-aws-elasti-cache.png)

**4. Provide the inputs for dynamic secret parameters**

**Secret Name** `string` *required*

Name by which you want the secret to be referenced

**Default TTL** `string` *required*

Default time-to-live for a generated secret (it is possible to modify this value after a secret is generated)

**Max TTL** `string` *required*

Maximum time-to-live for a generated secret.

**Region** `string` *required*

The region that the ElastiCache cluster is located in. *(e.g. us-east-1)*

**Access Key ID** `string` *required*

This is the access key ID of the AWS IAM user you created in the prerequisites. This will be used to provision and manage the dynamic secret leases.

**Secret Access Key** `string` *required*

This is the secret access key of the AWS IAM user you created in the prerequisites. This will be used to provision and manage the dynamic secret leases.

**CA(SSL)** `string`

A CA may be required if your DB requires it for incoming connections. This is often the case when connecting to a managed service.

**5. (Optional) Modify ElastiCache Statements**

**Username Template** `string` (default: \{\{randomUsername}})

Specifies a template for generating usernames. This field allows customization of how usernames are automatically created.

Allowed template variables are:

* `{{randomUsername}}`: Random username string.
* `{{unixTimestamp}}`: Current Unix timestamp at the time of lease creation.
* `{{identity.name}}`: Name of the identity that is generating the lease.
* `{{dynamicSecret.name}}`: Name of the associated dynamic secret.
* `{{dynamicSecret.type}}`: Type of the associated dynamic secret.
* `{{random N}}`: Random string of N characters.

Allowed template functions are:

* `truncate`: Truncates a string to a specified length.
* `replace`: Replaces a substring with another value.
* `uppercase`: Converts a string to uppercase.
* `lowercase`: Converts a string to lowercase.

Examples:

```yaml theme={"dark"}
{{ randomUsername }}                                            // 3POnzeFyK9gW2nioK0q2gMjr6CZqsRiX
{{ unixTimestamp }}                                             // 17490641580
{{ identity.name }}                                             // <identity-name>
{{ random 5 }}                                                  // x9K2m
{{ truncate identity.name 4 }}                                  // test
{{ replace identity.name '<identity-name>' 'new-value' }}       // new-value
```

**Customize ElastiCache Statement** `string`

If you want to provide specific privileges for the generated dynamic credentials, you can modify the ElastiCache statement to your needs. This is useful if you want to only give access to a specific resource.

**6. Click `Submit`**

After submitting the form, you'll see a dynamic secret created in the dashboard.

> [!NOTE]
>
> If this step fails, you may have to add the CA certificate.

**7. Generate dynamic secrets**

Once you've successfully configured the dynamic secret, you're ready to generate on-demand credentials.
To do this, simply select 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.

![Dynamic Secret](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-lease-empty.png)

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.

![Provision Lease](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/provision-lease.png)

> [!TIP]
>
> Ensure that the TTL for the lease falls within the maximum TTL defined when configuring the dynamic secret.

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

## Audit or revoke leases

Once you have created one or more leases, you'll be able to access them by selecting 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 it's set time to live.

## Renew leases

To extend the life of the generated dynamic secret leases past its initial time to live, simply select the **Renew** button as illustrated below.

![Provision Lease](https://mintlify.s3.us-west-1.amazonaws.com/infisical/images/platform/dynamic-secrets/dynamic-secret-lease-renew.png)

> [!WARNING]
>
> Lease renewals can't exceed the maximum TTL set when configuring the dynamic secret
