Choose your learning style9 modes available
Introduction
Managing Apache Kafka infrastructure can be complex and time-consuming. Confluent Cloud is a fully managed Kafka service that handles the setup, scaling, and maintenance for you, so you can focus on building your applications.
When you want to stream data between applications without managing servers or clusters.
When you need a reliable, scalable messaging system but lack Kafka operational expertise.
When you want to quickly prototype or deploy event-driven applications without setup delays.
When you want automatic backups, monitoring, and security without manual configuration.
When you need Kafka that integrates easily with cloud services and scales on demand.
Commands
Log in to Confluent Cloud CLI and save your credentials for future commands.
Terminal
confluent login --save
Expected OutputExpected
Logged in successfully.
List all Kafka clusters available in your Confluent Cloud account to choose one for your work.
Terminal
confluent kafka cluster list
Expected OutputExpected
ID NAME TYPE CLOUD REGION lkc-123abcde456fgh78 example-cluster Basic aws us-east-1
Create a new Kafka topic named 'example-topic' in the specified cluster to start sending and receiving messages.
Terminal
confluent kafka topic create example-topic --cluster lkc-123abcde456fgh78
Expected OutputExpected
Created topic "example-topic" on cluster "lkc-123abcde456fgh78".
--cluster - Specifies the Kafka cluster where the topic will be created.
List all topics in the specified Kafka cluster to verify the topic creation.
Terminal
confluent kafka topic list --cluster lkc-123abcde456fgh78
Expected OutputExpected
Name Partitions Replicas example-topic 1 3
--cluster - Specifies the Kafka cluster to list topics from.
Key Concept

If you remember nothing else, remember: Confluent Cloud lets you use Kafka without managing servers, making streaming data easier and faster.

Common Mistakes
Trying to create a topic without specifying the cluster ID.
The CLI needs to know which Kafka cluster to create the topic in; without it, the command fails.
Always include the --cluster flag with the correct cluster ID when creating or managing topics.
Not logging in before running Confluent Cloud commands.
Commands require authentication; without login, they will not work and show errors.
Run 'confluent login --save' first to authenticate your CLI session.
Summary
Log in to Confluent Cloud CLI to authenticate your session.
List available Kafka clusters to select where to work.
Create Kafka topics in your chosen cluster to organize your data streams.
Verify topic creation by listing topics in the cluster.
