I need to pull secrets(credentials) from AWS Parameters Store. Can anyone please let me know on how to use the credentials which is stored in aws parameter store

I have a project in Laravel 8 and I have some secret env parameters and I do not want to ship them with my application to github. I will deploy my application with github actions to AWS beanstalk. How do I keep all the secrets secure and put them to EC2 instance when all application deployed.
There are multiple ways to do that and you should not send your env file with your application to github.
You can use beanstalk's own parameter store page. However, if you do that another developer who has access to your AWS account can see all the env parameters. It is simple key value store page.
Benastalk Panel -> (Select Your Environment) -> Configuration -> Software
Under the systems manager there is a service called Parameter Store (this is my prefered way)
In here, You can add as much as parameter as you like securely. You can simply add string parameters as well as secure (like password or api keys) strings also integers but string and secure types are my favorites.
You can split all you parameters by path like "APP_NAME/DB_NAME" etc.
You should get all the parameters from Parameter Store to your EC2 instance and put them on newly created .env file.
There is github secrets in github actions and you can put all your secret parameters to github secrets page. You can get all the secrets from github secrets and put your secrets to your application and ship from github to AWS directly.
You can go to settings in your repository and see this page:
I'm working with some Kaggle project. Using Python library for BigQuery on my laptop, I can successfully download the dataset after passing the authentication credential by environment variable GOOGLE_APPLICATION_CREDENTIALS. As the documentation explains, this environment variable points to the location of a JSON file containing the credential.
Now I want to run this code on Amazon Lambda using Chalice. I know there's an option for environment variable in Chalice, but I don't know how to include a JSON file inside of a Chalice app and pass its location as an environment variable. Moreover, I'm not sure whether it's safe to pass the credential as a JSON file in Chalice.
Does anyone have some experience on how to pass Google Credential as an environment variable for Chalice app?
You could just embed the contents of the JSON file as an environment variable in Chalice, and then use the GCP Client.from_service_account_info() method to load credentials from memory instead of a file. This would not be advised since your private GCP credentials would then likely be committed to source control.
Might I suggest that you entertain other approaches to passing your GCP credentials other than environment variables. You could store this JSON object in AWS System Manager Parameter Store as a secure parameter. Your AWS Lambda function could then use the boto3 ssm.get_parameter() method when needed.
You could also consider AWS Secrets Manager as another similar alternative.
I am writing a serverless application which is connected to DynamoDB.
Currently I am reading the access key ID and security access key from a json file.
I am going to use Jenkins for CI and need a way to secure these keys.
What I am going to do is setting the keys as environmental variables and read them in the application. But the problem is I don't know how to set the environmental variables every time a lambda function is started.
I have read there's a way to configure this in serverless.yml file, but don't know how.
How to achieve this?
Don't use environment variables. Use the IAM role that is attached to your lambda function. AWS Lambda assumes the role on your behalf and sets the credentials as environment variables when your function runs. You don't even need to read these variables yourself. All of the AWS SDKs will read these environment variables automatically.
There's a good guide on serverless security, which among other topics, cover this one as well. It's similar to the OWASP top 10:
In general, the best practice would be to use the AWS Secrets Manager, together with SSM parameter store.
Assuming you create a Lambda ARN and Publish it, what are the default IAM permissions for that Lambda ARN?
i.e. can anyone go ahead and use it if they have the ARN?
When you create a lambda, you have to assign an IAM role to it. There are no predefined roles, although there are some predefined policies that you can assign to a role. As a minimum you would want to allow it to write logs to CloudWatch. If you wanted the lambda to access an S3 bucket, that policy would need to be assigned to the role.
The role you assign to a Lambda only defines what that Lambda can do, not what can invoke it. You can assign triggers for other AWS services to invoke the Lambda, but you can't say set a policy in the lambda role or trigger that would allow anything to invoke it.
If you wanted to invoke the lambda directly (e.g. though an SDK), you would need an IAM role that had permission to invoke that lambda.
The ARN (Amazon Resource Name) is just a naming convention that AWS uses to find something.
I wish to create the following using Cloudformation:
An autoscale group with a single spot instance, with an assigned route53 record which will always be directed to the instance, even if the instance is replaced.
I know how to do this with the Ruby API (not cloudformation).
How can I define this using Cloudformation ?
You have two options:
Option #1: Update R53 in your spot instance, after it boots:
In your Cloudformation template create an IAM role with permissions to update the appropriate R53 record
Assign that role to your spot instance
When your spot instance initializes have it update R53 directly via the REST APIs. I usually do this by setting a shell script in the UserData and have cloudinit run it on boot.
To update via Ruby you'll need the access id, access key and security token. Since you assigned an IAM role to the instance these are available via the Metadata API. Most libraries automatically pull out these values so you might not even need to do it manually. Boto and the nodejs SDK does it automatically.
Option #2: Use an ELB
In your CloudFormation create an ELB
In your CloudFormation create an R53 alias record that points at the ELB's DNS name
If cost is a factor, an ELB may be a little expensive to just add an extra layer of indirection.
