Reference Secrets in AWS Secrets Manager

AWS Secrets Manager is a fully managed service that you can integrate with API7 Enterprise to securely store, manage, and retrieve sensitive information such as API keys, passwords, and other types of credentials. It allows automatic rotation of secrets, reducing the risk of credentials being exposed over time.

This tutorial demonstrates how to integrate API7 Enterprise with AWS Secrets Manager, enabling you to securely store and reference consumer credentials and plugin configurations.

Below is an interactive demo providing a hands-on introduction to storing and retrieving key-auth secrets in AWS Secrets Manager with API7 Enterprise.

Prerequisites

1. Install API7 Enterprise.
2. Have at least one gateway instance in your gateway group.
3. Have an AWS account to access IAM and Secrets Manager modules.

Obtain IAM Access Key ID and Secret Access Key

Obtain the IAM user access key and secret access key, which will be configured in API7 Enterprise in the next step to access AWS Secrets Manager.

note

Please ensure that the appropriate permissions are correctly assigned to users to avoid validation failures due to insufficient permissions.

Add Secret Provider in Gateway Group

Dashboard

1. Select Secret Providers of your gateway group from the side navigation bar, then click Add Secret Provider.
2. From the dialog box, do the following:

• In the Secret Provider ID field, enter my-secrets-manager.
• In the Secret Manager field, choose AWS Secrets Manager.
• In the Region field, choose the region of your AWS Secrets Manager service. For example, us-east-1.
• Fill in the Access Key ID and Secret Access Key fields with access key and secret access key obtained in the last step.
• Click Add.

ADC

Reference Secrets to Create Consumer Credential

The following sensitive field in consumer credentials can be stored in an external secret manager (HashiCorp Vault, AWS Secrets Manager, etc.) and referenced in API7 Enterprise:

• key in Key Authentication credential
• password in Basic Authentication credential
• secret, public key in JWT Authentication credential
• secret_key in HMAC Authentication credential

Add a Consumer

Dashboard

1. Select Consumers of your gateway group from the side navigation bar.
2. Click Add Consumer.
3. From the dialog box, do the following:

• In the Name field, enter Alice.
• Click Add.

ADC

To use ADC to create a consumer, create the following configuration:

consumer.yaml

consumers:
  - username: Alice

Ingress Controller

Not supported yet.

Create a Secret in AWS Secrets Manager

In this section, you will be creating a secret to store consumer credentials for user alice. You can also refer to Create an AWS Secrets Manager secret.

1. Navigate to AWS Secrets Manager in the console and store a new secret. Choose Other type of secret as the secret type and enter the key name alice-key-auth and the value alice-key in the key-value pairs.
2. In the next step, configure the secret name to be alice-credentials and optionally add a description.
3. Click Next to review the rest of the information and finish the secret creation. You should see the secret listed in AWS Secrets Manager.
4. Repeat to create more key/value pairs for other consumer credentials:

• For basic authentication credential: password: alice-password.
• For JWT authentication credential: secret: alice-secret.
• For HMAC authentication credential: secret-key: alice-secret-key.

Add Key Authentication Credential

Dashboard

1. Select Consumers of your gateway group from the side navigation bar.
2. Select your target consumer, for example, Alice.
3. Under the Credentials tab, click Add Key Authentication Credential.

• In the Name field, enter primary-key.
• In the Key field, choose Reference from Secret Provider, then enter $secret://aws/my-secrets-manager/alice-credentias/alice-key-auth.
• Click Add.

note

All secret references start with $secret://. aws is Secret Manager Name of the secret provider, my-secrets-manager is Secret Provider ID on the API7 Enterprise dashboard. alice-credentials is Secret Name and alice-key-auth is Key Name you created on AWS Secrets Manager console.

ADC

To use ADC to create a consumer with key-auth, update your configuration:

• In the Name field, enter primary-basic.
• In the Username field, enter alice.
• In the Password field, choose Reference from Secret Provider, then enter $secret://aws/my-secrets-manager/alice-credentias/password.
• Click Add.

note

All secret references start with $secret://. aws is Secret Manager and my-secrets-manager is the Secret Provider ID.

Validate

See Enable Key Authentication for APIs for instructions, and enable the Key Auth Plugin on the service level.

Send a request to the route with the valid credential:

curl -i "http://127.0.0.1:9080/ip" -H 'apikey: alice-key'

You should receive an HTTP/1.1 200 OK response.

note

alice-key is the value of your key/value pair created on AWS Secrets Manager rather than the key name.

• For basic authentication credentials, validate with: password: alice-password.
• For JWT authentication credentials, validate with: secret: alice-secret.
• For HMAC authentication credentials, validate with: secret-key: alice-secret-key.

Reference Secrets to Enable Plugin

The following sensitive field in plugin configurations can be stored in an external secret manager(HashiCorp Vault, AWS Secrets Manager, etc.) and referenced in API7 Gateway:

Plugin	Field
Limit Count	redis_username, redis_password
Authz-Casdoor	client_id, client_secret
Wolf RBAC	appid
LDAP Authentication	user_dn

This section demonstrates configuring limit-count plugin as an example.

Create a Secret

Create a secret using the key/value pair username:api7 and password:redis-api7, under the secret name redis in your AWS Secrets Manager.

Configure limit-count Plugin

For where and how to enable the limit-count plugin, refer to Apply Rate Limiting to APIs.

Dashboard

Add the following configuration to the JSON Editor:

{
  "count": 3,
  "time_window": 60,
  "key_type": "var",
  "rejected_code": 429,
  "rejected_msg": "Too many requests",
  "key": "remote_addr",
  "policy": "redis",
  "redis_host": "127.0.0.1",
