Surface Forms

docker singular

dockers plural

Morphology

docker = dock (opaque) = dock + er

The computing sense is a branded and metaphorical extension based on container-shipping imagery, so the meaning is not directly recoverable from dock plus -er.

Etymology

Docker was named to make you think of a dock and shipping 'containers' ('boxes for goods') that move easily between ships and trucks. So a Docker container is like a portable box for a program, which explains the software name.
