Create a topic in docker apache/kafka

I’m following this guide https://kafka.apache.org/quickstart to run kafka locally using docker. On step 2 I run

docker pull apache/kafka:3.7.0
docker run -p 9092:9092 apache/kafka:3.7.0

Then, on step 3, I login into the container using Docker Desktop and run

bin/kafka-topics.sh --create --topic quickstart-events --bootstrap-server localhost:9092

But get an error /bin/sh: bin/kafka-topics.sh: not found. What am I doing wrong. Or there is some error in the manual?

    Error "/bin/sh: bin/kafka-topics.sh : not found" indicates that the system cannot find the executable file kafka-topics.sh . This can happen if you are trying to run a command outside the Docker container or if you have not properly configured the environment to work with Kafka inside the container.

    You may have run the command bin/kafka-topics.sh outside the Apache Kafka container. To fix this, you need to log into the container first and then run the command from there. Here’s how to do it:

    Log in to the Apache Kafka container:

    docker exec -it <container_id> bash
    Replace <container_id> with the ID of your Apache Kafka container. You can find it using the docker ps command.
    After logging into the container, you can run the command bin/kafka-topics.sh Right there:

    bin/kafka-topics.sh –create –topic quickstart-events –bootstrap-server localhost:9092
    If you want to run the command from outside the container, you will need to copy the executable file. kafka-topics.sh to your local file system

    I checked the source code of the Dockerfile, and the correct bin directory is /opt/kafka/bin

    So you could either give the absolute path of the script, or do docker run -w /opt/kafka ... to set the working directory.

    Ideally, those scripts would be on the PATH, as they are with other kafka images
