Command Line Interface for Strimzi Kafka Operator

Strimzi Kafka CLI

Strimzi Kafka CLI is a CLI that helps traditional Apache Kafka users -both developers and administrators- to easily adapt Strimzi, a Kubernetes operator for Apache Kafka.

Intention here is to ramp up Strimzi usage by creating a similar CLI experience with traditional Apache Kafka binaries.

kfk command stands for the usual kafka-* prefix of the Apache Kafka runnable files which are located in bin directory. There are options provided like topics, console-consumer, etc. which also mostly stand for the rest of the runnable file names like kafka-topic.sh.

However, because of the nature of Strimzi and its capabilities, there are also unusual options like clusters which is used for cluster configuration or users which is used for user management and configuration.

Following is the high-level output of the Strimzi Kafka CLI:

External Dependencies

kubectl and Strimzi resources are the tools that Strimzi Kafka CLI uses. These dependencies are automatically downloaded when the first kfk command is run. You can always check the dependency versions of your CLI with the following command:

kfk version

If you want to change the kubectl and Strimzi resources folder, you can simply change their version with the help of some environment veriables in order to let Strimzi Kafka CLI download the version you want, or change the PATH of any if you want to use a custom kubectl or Strimzi binary folder. Current versions are recommended, so use these environment variables at your own risk.

STRIMZI_KAFKA_CLI_BASE_PATH: Set this if you want to have a custom Strimzi Kafka CLI folder. It is set in ~/.strimzi-kafka-cli as default.

STRIMZI_KAFKA_CLI_STRIMZI_VERSION: Set this if you want to use a different Strimzi version.

STRIMZI_KAFKA_CLI_STRIMZI_PATH: Set this if you want to use a custom Strimzi/AMQ Streams.

STRIMZI_KAFKA_CLI_KUBECTL_VERSION Set this if you want to use a different kubectl version.

STRIMZI_KAFKA_CLI_KUBECTL_PATH: Set this if you want to use a custom kubectl.
