Dockerfile.busybox

# 3proxy.full is fully functional 3proxy build based on busybox:glibc
#
# Examples are for podman, for docker change 'podman' to 'docker'
#
#to build:
# podman build -f Dockerfile.busybox -t 3proxy.busybox .
#to run:
#
# echo nserver 8.8.8.8 >/path/to/local/config/directory/3proxy.cfg
# echo proxy -p3129 >>/path/to/local/config/directory/3proxy.cfg
# podman run --read-only -p 3129:3129 -v /path/to/local/config/directory:/etc/3proxy --name 3proxy.busybox 3proxy.busybox
#
# use "log" without pathname in config to log to stdout.
# plugins are located in /usr/local/3proxy/libexec (/libexec for chroot config)
# symlinked as /lib and /lib64 in both root and chroot configurations, so no need
# to specify full path to plugin. SSLPlugin is supported.
#
# Since 0.9.6 image is distroless, no reason to use chroot, chroot
# configuration is supported for compatibility only.
