How to secure kafka Topic with username and password from CLI/command line?

Question

I have installed Docker on my Windows 10 and also installed Kafka. I have created a "test" Topic inside a Kafka cluster. Now I want to secure the Topic with a simple username and password. I am super new to Kafka, any help would really be appreciated.

To run Kafka commands, I am using windows "Power Shell".

I have tried running a few commands on the command line

To create Topics:- kafka-topics --create --topic test --partitions 1 --replication-factor 1 --if-not-exists --zookeeper zookeeper:2181

To secure Topic I used command: kafka-acls --topic test --producer --authorizer-properties --zookeeper zookeeper:2181 --add --allow-principal User:alice

Unfortunately, it says "bash: afka-acl: command not found"

Do I need to include anything in the Kafka configuration file? or Is it possible to just run commands from power shell and secure Topic?

Securing with username and password is the same as ACL or different?

Answer 1

Kafka support authentication of connections to brokers from clients (producers and consumers) using

SSL

SASL (Kerberos) and SASL/PLAIN

This need configuration changes in for both broker and clients. What you are asking for seems like SASL plain. However as mentioned above this cannot be done from CLI and required configuration changes. If you follow the steps in the documentation link, it is pretty straightforward.

ACL is authorization which defines which user has access to what topics. See this link
