Alpine Dockerfile Advantages of --no-cache Vs. rm /var/cache/apk/*

Question

When creating Dockerfiles using the Alpine image, I have often seen the use of the apk --no-cache and other times it is committed and instead I see rm /var/ca

Answer 1

I think this is a design style. The essence of cache is to reuse, for example, multiple containers can mount the same cached file system without repeatedly downloading it from the network.
