: This is an option used to specify port mapping between the host machine and the container. The${host_port}
represents the port number on the host machine, and${container_port}
represents the port number within the container. By specifying this option, you can access the container's service running on${container_port}
from the specified${host_port}

: This specifies the container image to run.${image}
represents the name of the image, and${tag}
