docker: Invalid hostPort:

The "Invalid hostPort" error in Docker usually indicates that you have specified an invalid port number when trying to map a host port to a container port.

To fix this error, make sure that the host port number you are specifying is not already in use by another process, and that it falls within the valid range of port numbers (typically 1-65535). Also, ensure that you are using the correct syntax for specifying the port mapping in your Docker command or compose file.

For example, if you want to map host port 8080 to container port 80, you would use the following syntax:

docker run -p 8080:80 my_image

If you still encounter issues, try running your Docker command with the `--verbose` flag to see more detailed error messages and troubleshoot further.
