Answer
Copying files into containers breaks immutability and leads to unpredictable deployments.
Quick Answer
docker cp copies files between a running container and the host. It's a one-time manual operation — not automated, not version controlled, not part of the image build. In production, files should be in the image or in volumes from the start. Using docker cp to "fix" a running container creates snowflake servers and hides real problems.
