Configuration examples
Multiple bootstrap servers:
kaskade admin -b my-kafka:9092,my-kafka:9093

Consume and deserialize:
kaskade consumer -b my-kafka:9092 -t my-topic -k json -v json

Consuming from the beginning:
kaskade consumer -b my-kafka:9092 -t my-topic -x auto.offset.reset=earliest

Schema registry simple connection and avro deserialization:
kaskade consumer -b my-kafka:9092 \
-s url=http://my-schema-registry:8081 \
-t my-topic -k avro -v avro

For more information about Schema Registry configurations go
to: Confluent Schema Registry client.

SSL encryption example:
kaskade admin -b my-kafka:9092 -x security.protocol=SSL

For more information about SSL encryption and SSL authentication go

Confluent cloud admin and consumer:
kaskade admin -b ${BOOTSTRAP_SERVERS} \
-x security.protocol=SASL_SSL \
-x sasl.mechanism=PLAIN \
-x sasl.username=${CLUSTER_API_KEY} \
-x sasl.password=${CLUSTER_API_SECRET}

kaskade consumer -b ${BOOTSTRAP_SERVERS} \
-x security.protocol=SASL_SSL \
-x sasl.mechanism=PLAIN \
-x sasl.username=${CLUSTER_API_KEY} \
-x sasl.password=${CLUSTER_API_SECRET} \
-s url=${SCHEMA_REGISTRY_URL} \
-s basic.auth.user.info=${SR_API_KEY}:${SR_API_SECRET} \
-t my-topic \
-k string \
-v avro

Running with docker:
docker run --rm -it --network my-networtk sauljabin/kaskade:latest \
admin -b my-kafka:9092

docker run --rm -it --network my-networtk sauljabin/kaskade:latest \
consumer -b my-kafka:9092 -t my-topic

Protobuf consumer:
Install protoc command:
brew install protobuf

Generate a Descriptor Set file from your .proto file:
protoc --include_imports \
--descriptor_set_out=my-descriptor.desc \
--proto_path=${PROTO_PATH} \
${PROTO_PATH}/my-proto.proto

Consume using my-descriptor.desc file:
kaskade consumer -b my-kafka:9092 -x auto.offset.reset=earliest \
-k string -v protobuf \
-t my-protobuf-topic \
-p descriptor=my-descriptor.desc -p value=mypackage.MyMessage
