AWS Secrets Manager

Since Camel 3.9

Only producer is supported

The AWS Secrets Manager component supports list secret AWS Secrets Manager service.

Prerequisites

You must have a valid Amazon Web Services developer account, and be signed up to use Amazon Secrets Manager. More information is available at AWS Secrets Manager.

URI Format

aws-secrets-manager://label[?options]

You can append query options to the URI in the following format:

?options=value&option2=value&…​

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

At the component level, you set general and shared configurations that are, then, inherited by the endpoints. It is the highest configuration level.

For example, a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

You can configure components using:

  • the Component DSL.

  • in a configuration file (application.properties, *.yaml files, etc).

  • directly in the Java code.

Configuring Endpoint Options

You usually spend more time setting up endpoints because they have many options. These options help you customize what you want the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from), as a producer (to), or both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders.

Property placeholders provide a few benefits:

  • They help prevent using hardcoded urls, port numbers, sensitive information, and other settings.

  • They allow externalizing the configuration from the code.

  • They help the code to become more flexible and reusable.

The following two sections list all the options, firstly for the component followed by the endpoint.

Component Options

The AWS Secrets Manager component supports 23 options, which are listed below.

Name Description Default Type

binaryPayload (producer)

Set if the secret is binary or not.

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

operation (producer)

Required The operation to perform.

Enum values:

  • listSecrets

Static credentials, Default Credential Provider and Profile Credentials Provider

You have the possibility of avoiding the usage of explicit static credentials by specifying the useDefaultCredentialsProvider option and set it to true.

The order of evaluation for Default Credentials Provider is the following:

  • Java system properties - aws.accessKeyId and aws.secretKey.

  • Environment variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

  • Web Identity Token from AWS STS.

  • The shared credentials and config files.

  • Amazon ECS container credentials - loaded from the Amazon ECS if the environment variable AWS_CONTAINER_CREDENTIALS_RELATIVE_URI is set.

  • Amazon EC2 Instance profile credentials.

You have also the possibility of using Profile Credentials Provider, by specifying the useProfileCredentialsProvider option to true and profileCredentialsName to the profile name.

Only one of static, default and profile credentials could be used at the same time.

For more information about this you can look at AWS credentials documentation

Using AWS Secrets Manager Property Function

To use this function, you’ll need to provide credentials to AWS Secrets Manager Service as environment variables:

export $CAMEL_VAULT_AWS_ACCESS_KEY=accessKey
export $CAMEL_VAULT_AWS_SECRET_KEY=secretKey
export $CAMEL_VAULT_AWS_REGION=region

You can also configure the credentials in the application.properties file such as:

camel.vault.aws.accessKey = accessKey
camel.vault.aws.secretKey = secretKey
camel.vault.aws.region = region

If you want instead to use the AWS default credentials provider, you’ll need to provide the following env variables:

export $CAMEL_VAULT_AWS_USE_DEFAULT_CREDENTIALS_PROVIDER=true
export $CAMEL_VAULT_AWS_REGION=region

You can also configure the credentials in the application.properties file such as:

camel.vault.aws.defaultCredentialsProvider = true
camel.vault.aws.region = region

It is also possible to specify a particular profile name for accessing AWS Secrets Manager

export $CAMEL_VAULT_AWS_USE_PROFILE_CREDENTIALS_PROVIDER=true
export $CAMEL_VAULT_AWS_PROFILE_NAME=test-account
export $CAMEL_VAULT_AWS_REGION=region

You can also configure the credentials in the application.properties file such as:

camel.vault.aws.profileCredentialsProvider = true
camel.vault.aws.profileName = test-account
camel.vault.aws.region = region

At this point, you’ll be able to reference a property in the following way:

<camelContext>
    <route>
        <from uri="direct:start"/>
        <to uri="{{aws:route}}"/>
    </route>
</camelContext>

Where route will be the name of the secret stored in the AWS Secrets Manager Service.

You could specify a default value in case the secret is not present on AWS Secret Manager:

<camelContext>
    <route>
        <from uri="direct:start"/>
        <to uri="{{aws:route:default}}"/>
    </route>
</camelContext>

In this case, if the secret doesn’t exist, the property will fall back to "default" as value.

Also, you are able to get a particular field of the secret, if you have, for example, a secret named database of this form:

{
  "username": "admin",
  "password": "password123",
  "engine": "postgres",
  "host": "127.0.0.1",
  "port": "3128",
  "dbname": "db"
}

You’re able to do get single secret value in your route, like for example:

<camelContext>
    <route>
        <from uri="direct:start"/>
        <log message="Username is {{aws:database/username}}"/>
    </route>
</camelContext>

Or re-use the property as part of an endpoint.

You could specify a default value in case the particular field of secret is not present on AWS Secret Manager:

<camelContext>
    <route>
        <from uri="direct:start"/>
        <log message="Username is {{aws:database/username:admin}}"/>
    </route>
</camelContext>

In this case, if the secret doesn’t exist or the secret exists, but the username field is not part of the secret, the property will fall back to "admin" as value.

There is also the syntax to get a particular version of the secret for both the approach, with field/default value specified or only with secret:

<camelContext>
    <route>
        <from uri="direct:start"/>
        <to uri="{{aws:route@bf9b4f4b-8e63-43fd-a73c-3e2d3748b451}}"/>
    </route>
</camelContext>

This approach will return the RAW route secret with the version 'bf9b4f4b-8e63-43fd-a73c-3e2d3748b451'.

<camelContext>
    <route>
        <from uri="direct:start"/>
        <to uri="{{aws:route:default@bf9b4f4b-8e63-43fd-a73c-3e2d3748b451}}"/>
    </route>
</camelContext>

This approach will return the route secret value with version 'bf9b4f4b-8e63-43fd-a73c-3e2d3748b451' or default value in case the secret doesn’t exist or the version doesn’t exist.

<camelContext>
    <route>
        <from uri="direct:start"/>
        <log message="Username is {{aws:database/username:admin@bf9b4f4b-8e63-43fd-a73c-3e2d3748b451}}"/>
    </route>
</camelContext>

This approach will return the username field of the database secret with version 'bf9b4f4b-8e63-43fd-a73c-3e2d3748b451' or admin in case the secret doesn’t exist or the version doesn’t exist.

For the moment we are not considering the rotation function if any are applied, but it is in the work to be done.

The only requirement is adding the camel-aws-secrets-manager jar to your Camel application.

Automatic Camel context reloading on Secret Refresh

Being able to reload Camel context on a Secret Refresh could be done by specifying the usual credentials (the same used for AWS Secret Manager Property Function).

With Environment variables:

export $CAMEL_VAULT_AWS_USE_DEFAULT_CREDENTIALS_PROVIDER=accessKey
export $CAMEL_VAULT_AWS_REGION=region

or as plain Camel main properties:

camel.vault.aws.useDefaultCredentialProvider = true
camel.vault.aws.region = region

Or by specifying accessKey/SecretKey and region, instead of using the default credentials provider chain.

To enable the automatic refresh, you’ll need additional properties to set:

camel.vault.aws.refreshEnabled=true
camel.vault.aws.refreshPeriod=60000
camel.vault.aws.secrets=Secret
camel.main.context-reload-enabled = true

where camel.vault.aws.refreshEnabled will enable the automatic context reload, camel.vault.aws.refreshPeriod is the interval of time between two different checks for update events and camel.vault.aws.secrets is a regex representing the secrets we want to track for updates.

Note that camel.vault.aws.secrets is not mandatory: if not specified the task responsible for checking updates events will take into accounts or the properties with an aws: prefix.

Automatic Camel context reloading on Secret Refresh with Eventbridge and AWS SQS Services

Another option is to use AWS EventBridge in conjunction with the AWS SQS service.

On the AWS side, the following resources need to be created:

  • an AWS Couldtrail trail

  • an AWS SQS Queue

  • an Eventbridge rule of the following kind

{
  "source": ["aws.secretsmanager"],
  "detail-type": ["AWS API Call via CloudTrail"],
  "detail": {
    "eventSource": ["secretsmanager.amazonaws.com"]
  }
}

This rule will make the event related to AWS Secrets Manager filtered

  • You need to set the a Rule target to the AWS SQS Queue for Eventbridge rule

  • You need to give permission to the Eventbrige rule, to write on the above SQS Queue. For doing this you’ll need to define a json file like this:

{
    "Policy": "{\"Version\":\"2012-10-17\",\"Id\":\"<queue_arn>/SQSDefaultPolicy\",\"Statement\":[{\"Sid\": \"EventsToMyQueue\", \"Effect\": \"Allow\", \"Principal\": {\"Service\": \"events.amazonaws.com\"}, \"Action\": \"sqs:SendMessage\", \"Resource\": \"<queue_arn>\", \"Condition\": {\"ArnEquals\": {\"aws:SourceArn\": \"<eventbridge_rule_arn>\"}}}]}"
}

Change the values for queue_arn and eventbridge_rule_arn, save the file with policy.json name and run the following command with AWS CLI

aws sqs set-queue-attributes --queue-url <queue_url> --attributes file://policy.json

where queue_url is the AWS SQS Queue URL of the just created Queue.

Now you should be able to set up the configuration on the Camel side. To enable the SQS notification add the following properties:

camel.vault.aws.refreshEnabled=true
camel.vault.aws.refreshPeriod=60000
camel.vault.aws.secrets=Secret
camel.main.context-reload-enabled = true
camel.vault.aws.useSqsNotification=true
camel.vault.aws.sqsQueueUrl=<queue_url>

where queue_url is the AWS SQS Queue URL of the just created Queue.

Whenever an event of PutSecretValue for the Secret named 'Secret' will happen, a message will be enqueued in the AWS SQS Queue and consumed on the Camel side and a context reload will be triggered.
