Identifying a container by name 

You can identify a container using one of three identifiers:

• The UUID long identifier, for example, a415f4b646e3a715dc9fa446744934fc99ea33dd28761456381b9b7f6dcaf76b
• The UUID short identifier, for example, a415f4b646e3
• The name, for example, nostalgic_euler

If you do not assign a name to a container when you run docker run, the Docker daemon will auto-generate a name for you, which has the structure <adjective>_<noun>. However, it might be more helpful to assign a name that describes the container’s function within the context of the whole application. We can do that through the --name flag.
