docker build for a 911-dispatch helper is unexpectedly large and slow. What should the team understand about the build context?
Select an answer to reveal the explanation.
Short Explanation
Build context is the suitcase you hand the daemon. Without a .dockerignore packing list, you may ship the whole closet—including secrets and .git—and wonder why the trip is slow.
Full Explanation
docker build sends the context directory to the daemon. A missing or weak .dockerignore can include .git, local secrets, and bulky dependency folders, slowing builds and risking accidental COPY of unintended files. Curating the context is part of professional image hygiene.
