Caddy Web Server

Official Caddy’s image is based on Alpine which is using musl libc⁠ instead of glibc and friends⁠. This image is based on openSUSE Base Container Image, contains glibc and coreutils, and a stripped-down version of Tumbleweed Base Image without Zypper and the RPM package manager.

Containerfile commands:
