docker container named dreamy_ritchie?
Solution 1:
If you don't supply a name to the container you create, docker will assign one of the form "adjective_scientist", where "adjective" is from a list of adjectives, and "scientist" is from a list of scientists and mathematicians.
It's a way of assigning a unique name to the container that is easier to work with than, say, 08fd482ac8913ed7.
