This PR switches the base image for
skeleton
fromalpine
tobusybox
. This reduces the image size (22.5MB vs 32.9MB) and update frequency (thebusybox
binary is the only executable component of the image; it is updated less frequently and has much fewer vulnerabilities than a full-fledged image).Also, because the
ADD
command can add files from a Git repository, we simplify the build process by not usinggit
. The build process will be faster because Docker does not need to execute anything in the foreign (emulated) architecture.Unlike #984, this PR does not require changes to VIP CLI.
