how to give topic access to one specific user?

Question

I am collecting the data from different resources, each resource has one specific topic for each client. I want to give the access for each user only to the corresponding topic, so they can't have access to all the topics. I am working with Kafka 0.10 and I am using Kafka tools. there is solution?

You need to configure Authorisation using ACL.

How to enable ACL:

In your server.properties file, you need to create an Authorizer by adding the following line:

authorizer.class.name=kafka.security.auth.SimpleAclAuthorizer

Now you need to follow the docs in order to properly configure ACL based on your use cases.

Adding ACLs

Now once everything is in place, let's assume you have a topic called testTopic to which you want to grant read and write access only to user called Bob from a host with IP 197.5.6.1:

bin/kafka-acls --authorizer-properties zookeeper.connect=localhost:2181 \
 --add \
 --allow-principal User:'Bob' --allow-host '197.5.6.1' \
 --operation Read --operation Write \
 --topic testTopic \
