The command "kcat -C -t ${topic} -b ${brokers}" is a command-line instruction using the Kafka Cat (kcat) tool to consume messages from a Kafka topic.

Here's what each part of the command does:

"kcat": Refers to the Kafka Cat tool, a command-line utility used for interacting with Apache Kafka clusters.
"-C": Specifies the command to consume messages from Kafka.
"-t ${topic}": Specifies the topic from which the messages should be consumed. The "${topic}" is a placeholder that should be replaced with the actual name of the topic you want to consume messages from.
"-b ${brokers}": Specifies the list of bootstrap brokers used to establish the initial connection with the Kafka cluster. The "${brokers}" is a placeholder that should be substituted with the actual list of Kafka brokers' addresses. Typically, multiple broker addresses are separated by commas.

By running this command, you will consume messages from a specific Kafka topic using the provided bootstrap brokers.
