Which protocol is responsible for determining the lifetime of packets in a network?

The process of building a container from a Dockerfile is as follows:

docker build -t image_name path_to_directory_with_dockerfile

For example, if the Dockerfile is in the current directory:

docker build -t myapp:latest .

After a successful build, the container can be run with:

docker run -d --name container_name image_name

Example:

docker run -d --name myapp_container myapp:latest

The -d option runs the container in detached mode. You can also expose ports with -p and pass environment variables with -e.
