I am currently setting up my aws s3 bucket for different environments so I can have data in dev, tqa, stg, and prd. The name of my bucket in dev is s3.dev.kafka.sink while in tqa it is named as s3.tqa.kafka.sink each associated with its correct env. The documentation in the Kafka Connect website doesn't specify how to be set the environments, so I did the following way, however I keep getting errors that the bucket name is not named properly.

I put it in the secret yaml file

apiVersion: kubernetes-client.io/v1
kind: ExternalSecret
metadata:
   name: kafka-sink-s3-secret
   namespace: namespace
spec:
   backendType: secretManager
   data:
       -key: s3.tqa.kafka.sink
        name: bucket_name
        property: bucket_name

While in deployment file

env:
   -name: bucket_name
    valueFrom:
        secretKeyRef:
         name:kaka-sink-s3-secret
         key: bucket_name

And I will specify the bucket name in the config: "s3.bucket.name":"'"$bucket_name"'"

But it fails to deploy. Any idea how can i specify as s3.{{ENV}}.kafka.sink so it runs the correct bucket name in their own env in aws
