Fargate environment variable redis.yaml - aws-fargate

Question

I have a microservice and I need to pass in a file redis.yaml to configure Elasticache for Redis.
Assume I have a file called redis.yaml with contents:
clusterServersConfig:
idleConnectionTimeout: 10000
pingTimeout: 1000
connectTimeout: 10000
timeout: 60000
retryAttempts: 3
retryInterval: 60000
And my application.properties I use:
redis.config.location=file:/opt/usr/conf/redis.yaml
In Kubernetes, I can just create a secret with --from-file redis.yaml and the application runs properly.
I do not know how to do the same with AWS Fargate. I believe it could be done with AWS SSM but any help/steps on how to do it would be appreciated.

Answer 1

For externalized configuration, Fargate supports environment variables. Environment variables can be passed in Task definition.
"environment": [
{ "name": "env_name1", "value": "value1" },
{ "name": "env_name2", "value": "value2" }
]
If it's sensitive information, store it in AWS SSM-Parameter store (you can use KMS) and specify the parameter key in the task definition.
{
"containerDefinitions": [{
"secrets": [{
"name": "environment_variable_name",
"valueFrom": "arn:aws:ssm:region:aws_account_id:parameter/parameter_name"
}]
}]
}
In your case, you can convert your yaml to JSON and store it in the Parameter store and refer it in the task definition.
