Is there a way to retrieve a secret from the AWS secret store using DefaultAWSCredentialsProviderChain java class?
If not please suggest a way to retrieve it? (I need this in the context of doing signature V4 signing the request to connect with AWS Neptune. For signature signing, I am using this example. But my secrets are in AWS secret manager, So How can I retrieve the secret from the secret store with DefaultAWSCredentialsProviderChain)
I'm not sure if Secrets Manager exposes a AWSCredentialsProvider interface, but even if they don't support one, it should be easy to write something up.
Here is a sample implementation that uses the Secrets Manager APIs to expose a credentials provider implmentation:
https://github.com/jenkinsci/aws-secrets-manager-credentials-provider-plugin/blob/0e12e02a759d13524ed7f5cd0125ef6eab47ff7d/src/main/java/io/jenkins/plugins/credentials/secretsmanager/AwsCredentialsProvider.java
Once you have something like this, just make sure you pass it to the SigV4Signer that you use in your application.
Reference: https://github.com/aws/amazon-neptune-sigv4-signer/blob/master/src/main/java/com/amazonaws/neptune/auth/NeptuneSigV4SignerBase.java#L77-L86
Hope this helps.
It is possible with aws secretsmanager
Use these docs

I was wondering if there are any migration guides for migrating from GKE Secrets to the Secret Manager API?
I'm not aware of any existing guides for doing this.
Basically, you'll need to
recreate all of your secrets in Secret Manager
modify your application code to use the Secrets Manager API to access the secrets
ensure you have Workload Identity enabled for your cluster
make sure your pod(s) use a identity with access to Secrets Manager.
assuming everything above works, delete your existing Secrets
By default, data in GKE secrets is stored in Base64 encoding, which is practically the same as plaintext. GCP Secret Manager are encrypted with Google-default encryption. With Google-default encryption, secret payloads are encrypted by keys managed by Google.
See this documentation.
We have an API app that uses Firebase Admin to send messages to devices.
Earlier, we used to specify the service account key using environment variable like GOOGLE_APPLICATION_CREDENTIALS="path_to_file.json".
But now, since we are shifting to AWS Elastic Container Service on Fargate, I am unable to figure out how to put this file in the container for AWS ECS.
Any advice highly appreciated.
Thanks
Solved it by storing the service key as a JSON Stringified environment variable & using admin.credential.cert() instead of defaultAppCredentials.
Refer: https://firebase.google.com/docs/reference/admin/node/admin.credential#cert
I would suggest instead AWS Secrets Manager that is purpose-built for storing secrets. Take a look to his blog post:
https://aws.amazon.com/blogs/compute/securing-credentials-using-aws-secrets-manager-with-aws-fargate/
Even better than using environment variables which have their own downsides, you can leverage AWS Parameter Store which is a secure way to manage secrets in the AWS environment (where secrets are encrypted both in transit and at rest).
You'd need to create an IAM role for Amazon ECS for your code to have access to the Parameter Store.
You may want to check this article: https://aws.amazon.com/blogs/compute/managing-secrets-for-amazon-ecs-applications-using-parameter-store-and-iam-roles-for-tasks/
Use the specific method from_service_account_info as described here. You then pass the content of the credentials json file as a dictionary.
Below code creates AWS Credentials where access and secret keys are explicitly supplied.
AWSCredentials credentials = new BasicAWSCredentials(
"<AWS accesskey>",
"<AWS secretkey>"
);
But the issue with this approach is in production I can not use it.
So what will be an equivalent java code that will obtain credential automatically from the aws credentials chain and create a credential object or some EC2 client.
There are several alternatives you can use to store and recover your credentials in production. You should check the official documentation by AWS about 'Using the Default Credential Provider Chain'. Basically, you can use any of these alternatives:
Environment variables.
Java system properties.
The default credential profiles file.
Amazon ECS container credentials.
Instance profile credentials.
Depending on which one you choose it would use a different code. You have guidelines on how to use them in the above link.
Right now I am passing the username and password in as environment variables. The variables are retrieved from a different file so the cloudformation stored using git does not contain the password and username which is good. But, right now they are stored in plaintext when looking at the lambda in the console.
What is the best practice for storing these credentials in the most cloud provider agnostic way? I basically just don't want to use KMS or any other key storing AWS service.
Just for completeness I have also considered storing the password in a dynamodb table. Then I would use IAM to be able to retrieve those credentials. But, those credentials are still stored in plaintext. If this is the best way to retrieve credentials is there a best way to encrypt it or this path not the best.
Thanks for all comments and advice.
We use AWS Secrets Manager for this exact situation. Works perfectly for us.
To retrieve the credentials (aws_access_key, aws_secret_access_key, aws_session_token) to access AWS services via the cli, we have to call a custom service first to get our temporary credentials. If the credentials have expired we need to retrieve new credentials.
Using boto it is possible to write a custom credential provider by extending boto.provider.Provider. Is something similar possible to extend the aws cli?
Although not documented, I know it is possible to write plugins for the aws cli. Can I leverage this functionality to implement my own credential retriever?
You'll need to create an object that implements the CredentialProvider class in botocore.
Once that's created you can have the CLI add it to the set of credential providers to check.
If you want an example of this, the AssumeRole credential provider is written as an "internal" plugin in the CLI. You'd need to do something similar to this. You'll get the credential_provider component from the session and then inject yours into the chain. You might want to take a look at the default set of providers and decide where your custom credential provider should be placed.
