Why a Docker image is called an 'image'
A Docker image is not a picture. The word traces through ISO files and CD-ROMs back to the 1960s, when an 'image' meant a faithful, byte-for-byte copy of storage — and the 'ROM' in CD-ROM is the same read-only idea Docker's immutable layers are built on.

Where the name Docker comes from
A docker is a longshoreman — the worker at a port who loads and unloads shipping containers. The software took its name from the work; the work took its metaphor from the 1956 standardisation of physical shipping containers. The container ecosystem inherited the maritime vocabulary.
