What does "Permission Denied" mean when attempting to access /bin/sh/ in Apache Kafka within a Docker container?

edit

"Permission Denied" error in Apache Kafka within a Docker container while attempting to access /bin/sh simply means that the user attempting to execute the command doesn't have the required permission to access the /bin/sh directory. It might be due to the fact that the user doesn't have the necessary executable permissions for the sh file or the entire directory, or the directory might be read-only for the user. In such cases, granting the necessary permissions to the user might resolve the issue.
