What does `docker build --no-cache` do?

✓Correct answer: Rebuilds every layer instead of reusing cached ones

3Builds the image without saving it on the host

Explanation

Useful when a cached RUN apt-get update or RUN npm ci layer hides newer packages. Normally the cache is what makes rebuilds fast.
