Kafka with SSL - write to a topic - authorization error - ssl

Question

I am trying to produce from a command line to a topic that is on a local Kafka cluster with SSL enabled.
Topic was just created with:
kafka-topics --zookeeper localhost:2181 --create --topic simple --replication-factor 1 --partitions 1
Command for producing is:
kafka-avro-console-producer \
--broker-list localhost:9092 --topic simple \
--property value.schema='{"type":"record","name":"myrecord","fields":[{"name":"f1","type":"string"}]}' \
--property schema.registry.url=http://localhost:8080
Typing:
{"f1": "Alyssa"}
ERROR:
{"f1": "Alyssa"}
Error when sending message to topic simple with key: null, value: 12 bytes with error:
(org.apache.kafka.clients.producer.internals.ErrorLoggingCallback:52) org.apache.kafka.common.errors.TopicAuthorizationException:
Not authorized to access topics: [simple]
How to add access to this topic?
What is the correct command for ACL (I am running it on my local machine).

Answer 1

Since you have an SSL protected cluster, then I suggest creating a config file, and using this parameter for the CLI to reference it.
--producer.config <String: config file> Producer config properties file. Note
that [producer-property] takes
precedence over this config
An example file would look like
bootstrap.servers=localhost:9092
# SSL related properties
security.protocol=SSL
ssl.keystore.location=/path/to/keystore-cert.jks
ssl.truststore.location=/path/to/truststore-cert.jks
ssl.key.password=xxxx
ssl.keystore.password=yyyy
ssl.truststore.password=zzzz
Otherise, you must pass each of these one-by-one onto the --property option

Answer 2

I got the same due to SSL properties, pls pass SSL.
below is sample for AVRO message
./kafka-avro-console-producer --topic <topic_name> --broker-list <broker:port> --producer.config ssl.properties --property schema.registry.url=<schema_registru_url (for avro msg)> --property value.schema="$(< /path/to/avro_chema.avsc)" --property key.schema='{"type":"string"}' --property parse.key=true --property key.separator=":"
