Alpine Linux 3.24, a minimal, security oriented Linux base with a very small footprint.
Alpine Linux is a security oriented, extremely small general purpose Linux distribution. It is built on musl libc and BusyBox rather than glibc and GNU coreutils, and it uses OpenRC as its init system rather than systemd. Alpine is best known as the base of a very large share of the world's container images, and the same properties that made it the default there, a tiny installed footprint, a small attack surface and a fast boot, apply equally when it runs as a full virtual machine.
Alpine is a collection of thousands of independently licensed packages rather than a single licensed product. This image is a clean Alpine 3.24 platform ready for you to build on.
The stock Alpine cloud image leaves the provisioned administrator account password locked, and because Alpine's OpenSSH is built without PAM that blocks every login including key based ones, so the machine arrives unreachable. cloudimg fixes that at first boot, installs sudo so the administrator actually has privilege escalation, and proves both on a fresh instance before shipping. Alpine has no unattended upgrades equivalent and no errata feed, so cloudimg pins the 3.24 stable branch and ships a daily patch job with cron genuinely enabled, since on a stock install cron sits in no runlevel and anything placed in the periodic directories never runs. Only Alpine's own main and community repositories are enabled, never edge or testing. No password, no bundled key and no shared SSH host key ships in the image, host keys are regenerated uniquely on every instance, and every deployment comes with a paired deploy guide and 24/7 cloudimg support.
