Subject: [PATCH] Remove additional `--update` for apk in Dockerfile

There is no need to use --update with --no-cache when using apk on
Alpine Linux, as using --no-cache will fetch the index every time and
leave no local cache, so the index will always be the latest without
temporary files remain in the image.
