FAQ
Frequently Asked Questions
Yes, in British and Commonwealth English, 'docker' is a standard term for a port worker. In the US, 'longshoreman' or 'stevedore' are more formal.
The connection is purely metaphorical. The software Docker is named after the shipping container metaphor—it 'packages' software into standardized units (containers) for easy transport and deployment, much like physical shipping containers revolutionized port work.
Yes, when referring to the specific containerization platform (the software product by Docker, Inc.), it is a proper noun and should be capitalized: 'Docker'. Use lowercase 'docker' only for the occupational term or in the generic verb form 'to dockerize'.
Yes, especially in computing. The verb 'to Dockerize' (or 'dockerize') is common, meaning to adapt an application to run within a Docker container. The occupational sense is rarely verbed.
A person employed to load and unload ships at a port.

Learning
Memory Aids
Mnemonic
Think of a DOCK worker who uses a DOCKer to DOCKerize software, putting it into a neat, portable container just like cargo on a ship.
Conceptual Metaphor
SHIPPING/CONTAINERS. The original meaning is literal (ships/ports). The computing meaning extends this: software applications are 'cargo' that is standardized, packaged, and shipped in 'containers' (Docker containers) for easy transport and deployment.
