Final test: Containers: Docker and compose

One correct answer

In a Dockerfile a long RUN step comes after COPY . /app, although it does not need the application files. Every code edit rebuilds it. What will you change?

• A Remove CMD, since it makes everything rebuild.
• B Build with --no-cache.
• C Build the image once more without edits to refresh the cache.
• D Move this RUN above COPY . /app.
