CloudFormation - How to add the bootsrap parameter to Ksql Server - apache-kafka

Question

I'm using CloudFormation scripts to build an EC2 container of Ksql Server (Docker container). I have already built the other components within MSK I.e Bootstrap servers and listeners.
Within the AWS::ECS::TaskDefinition I have tried to add the bootstrap servers and listeners by using the 'Container' & 'Environment' properties within 'ContainerDefinition'. Although doing this puts the EcsService in a stuck position as the status stays as CREATE_IN_PROGRESS.
# Creating the ECS Task for KsqlDB
EcsKsqlTask:
Type: AWS::ECS::TaskDefinition
Properties:
NetworkMode: awsvpc
Cpu: '256'
Memory: '1024'
RequiresCompatibilities:

Any help on any property I am missing would be greatly appreciated!
