Add an AWS secrets manager

You can use AWS Secrets Manager for your Harness secrets.

Unlike AWS KMS, AWS Secrets Manager stores both secrets and encrypted keys. With AWS KMS, Harness stores the secret in its Harness store and retrieves the encryption keys from KMS. For information on using an AWS KMS Secrets Manager, see Add an AWS KMS Secrets Manager.

This topic describes how to add an AWS Secret Manager in Harness.

Before you begin​

  • If you are adding an AWS Secrets Manager running on ROSA, you must also add an environment variable AWS_REGION with the appropriate region as its value.
    For example AWS_REGION=us-east-1.

Permissions: Test AWS Permissions​

Harness uses the same minimum IAM policies for AWS secret manager access as the AWS CLI.

The AWS account you use for the AWS Secret Manager must have the following policies at a minimum:

{  
    "Version": "2012-10-17",  
    "Statement": {  
        "Effect": "Allow",  
        "Action": [  
            "secretsmanager:Describe*",  
            "secretsmanager:Get*",  
            "secretsmanager:List*"   
        ],  
        "Resource": "*"  
    }  
}

These policies let you list secrets which will allow you to add the Secret Manager and refer to secrets, but it will not let you read secrets values.

The following policy list enables Harness to perform all the secrets operations you might need:

{  
    "Version": "2012-10-17",  
    "Statement": {  
        "Effect": "Allow",  
        "Action": [  
          "secretsmanager:CreateSecret",  
          "secretsmanager:DescribeSecret",  
          "secretsmanager:DeleteSecret",  
          "secretsmanager:GetRandomPassword",  
          "secretsmanager:GetSecretValue",  
          "secretsmanager:ListSecretVersionIds",  
          "secretsmanager:ListSecrets",  
          "secretsmanager:PutSecretValue",  
          "secretsmanager:UpdateSecret",
          "secretsmanager:TagResource"   
        ],  
        "Resource": "*"  
    }  
}

See Using Identity-based Policies (IAM Policies) for Secret Manager from AWS.

To test use the AWS account when running aws secretsmanager list-secrets on either the Harness Delegate host or another host.

Step 1: Add a Secret Manager​

This topic assumes you have a Harness Project set up. If not, see Create Organizations and Projects.

You can add a Connector from any module in your Project in Project SETUP, or in your Organization, or Account Resources.

In Connectors, click Connector.

In Secret Managers, click AWS Secrets Manager. The AWS Secrets Manager settings appear.

note

For information on restrictions on names and maximum quotas, see Quotas for AWS Secrets Manager.

Step 2: Overview​

Enter Name for your secret manager.

You can choose to update the ID or let it be the same as your secret manager's name. For more information, see Entity Identifier Reference.

Enter Description for your secret manager.

Enter Tags for your secret manager.

Click Continue.

Step 3: Details​

You can select the following options in Credential Type for authenticating with AWS:

  • AWS Access Key.
  • Assume IAM Role on Delegate.
  • Assume Role Using STS on Delegate.

Option: AWS Access Key​

Use your AWS IAM user login credentials.

Gather AWS - Access Key ID and AWS - Secret Access Key from the JSON for the Key Policy, or in the AWS IAM console, under Encryption keys.

For more information, see Finding the Key ID and ARN from Amazon.

AWS-Access Key ID​

Click Create or Select a Secret.

In the secret settings dialog, you can create/select a Secret and enter your AWS Access Key as it's value.

The AWS Access Key is the AWS Access Key ID for the IAM user you want to use to connect to Secret Manager.

AWS- Secret Access Key​

Click Create or Select a Secret.

You can either create a new Secret with your Access Key ID's secret key as its Value or use an existing secret.

Secret Name Prefix​

Enter Secret Name Prefix. All the secrets under this secret manager would have this prefix. For example, devops will result in secrets like devops/mysecret. The prefix is not a folder name.

Region​

Select the AWS Region for the Secret Manager.

Option: Assume IAM Role on Delegate​

If you select this option, Harness will authenticate using the IAM role assigned to the AWS host running the Delegate you select. You can select a Delegate using a Delegate Selector.

Refer to Secret Name Prefix and Region explained above to add these details.

Option: Assume Role Using STS on Delegate​

This option uses the AWS Security Token Service (STS) feature. Typically, you use AssumeRole within your account or for AWS cross-account access.

Refer to Secret Name Prefix and Region explained above to add these details.

Role ARN​

Enter the Amazon Resource Name (ARN) of the role that you want to assume. This role is an IAM role in the target deployment AWS account.

External ID​

If the administrator of the account to which the role belongs provided you with an external ID, then enter that value.

For more information, see How to Use an External ID When Granting Access to Your AWS Resources to a Third Party from AWS.

Assume Role Duration​

Enter the AssumeRole Session Duration. See Session Duration in the AssumeRole AWS docs.

Step 4: Setup Delegates​

In Setup Delegates, enter Selectors for specific Delegates that you want to allow to connect to this Connector.

Step 5: Test Connection​

Once the Test Connection succeeds, click Finish. You can now see the Connector in Connectors.​
