Describe the bug
Push to CF fails for aws service broker.

I am trying to deploy aws service broker to CF, But i am facing this error on cf push--

ERR I0811 11:25:53.153335   28 util.go:195] Did not find 'aws_access_key' and 'aws_secret_key' in params, using default chain.
ERR I0811 11:25:53.153399   28 aws_sdk.go:71] Parameter 'target_role_name' not set. Not assuming role.

You need to put a "command" in manifest that looks like the one used in the packaging/cloudfoundry/tile.yml file, and make sure that all the environment variables it uses are set in your manifest too. We've literally been working on the same problem today, and it's working ;-)

My manifest looks like this now for command section --

command: >
    export PARAM_OVERRIDE_${BROKER_ID}_all_all_all_region=${AWS_DEFAULT_REGION} ;
    export AWS_ACCESS_KEY_ID=${AWS_ACCESS_KEY_ID} ;
    export AWS_SECRET_ACCESS_KEY=${AWS_SECRET_ACCESS_KEY} ;
    export AWS_DEFAULT_REGION=${AWS_DEFAULT_REGION} ;
    ./cfnsb --logtostderr --prescribeOverrides=${PRESCRIBE} --v=${VERBOSITY} --brokerId=${BROKER_ID} --enableBasicAuth=true --insecure=${INSECURE} --port=${PORT} --region=${AWS_DEFAULT_REGION} --s3Bucket=${S3_BUCKET} --s3Key=${S3_KEY} --s3Region=${S3_REGION} --tableName=${TABLE_NAME} --templateFilter=${TEMPLATE_FILTER} --tlsCert=${TLS_CERT} --tlsKey=${TLS_KEY}
  disk_quota: 1G

PS : I downloaded Source code(zip) from https://github.com/awslabs/aws-servicebroker/releases/tag/v1.0.1
it has 2 files - cfnsb and manifest. i make changes in manifest and did cf push
