What is the point of a BusyBox docker image? In fact, our very first container demo used BusyBox back in 2013! How Rancher makes container adoption simple. Say you need something to happen that sets up the pod filesystem before your real container starts running then busybox is great at this.. As a concrete example the official redis image doesn't run redis as root and so it cannot access the filesystem. Not the answer you're looking for? You dont have to package together to a point anything you dont need. Alpine Linux performs well on resource-limited devices, which is fitting for developing simple applications or spinning up servers. There would be value to having an image with only busybox that statically links against musl libc (if everything you're going to add is in a non-C language), or an image with busybox that dynamically links against glibc (if you're going to add more binaries that need libc and aren't compatible with musl). What is the proper way to start dnsmasq in my docker ENTRYPOINT? While some developers express security concerns when using relatively newer images, Alpine has earned a solid reputation.
