This is a docker base image that can be used as a baseline for future containers that will be utilized for long-term deployments.

Base Distribution	Tag	Size
Ubuntu Bionic (18)	ubuntu-18-latest
Alpine 3.10	alpine-3.10-latest
Debian Bullseye (11)	debian-11-latest

• /usr/local/bin
  • log - This is used to print neat messages out to the docker console.
    • Usage: log $(basename $0) MESSAGE...
  • pkg-manager - This is used by inst-pkg and rm-pkg to get the package manager.
    • Usage: . pkg-manager which then sets the $MANAGER env variable in the calling script.
  • inst-pkg - This is a install script which allows me to use common syntax across debian and alpine images. It's especially handy since apt-get doesn't include the nice --virtual tag that apk does to easily install build dependencies not needed for further use.
    • Usage: inst-pkg [--virtual NAME ] PKG [PKG...]
  • rm-pkg - This is a remove script which allows me to use common syntax across debian and alpine images. It's especially handy since apt-get doesn't include the nice --virtual tag that apk does to easily remove build dependencies not needed for further use.
    • Usage: rm-pkg PKG [PKG...]
  • check_and_terminate_process - Since Alpine Linux provides a minimal install and the s6-overlay doesn't provide a traditional method of verifying services this is a basic but powerful script I have written that is an all-in-one solution to find, terminate and possibly force kill processes. This utilizes the minimized pgrep provided by busybox in Alpine Linux.
    • Usage: check_and_terminate_process "name_of_service"

• Glider Labs rootfs Builder
• S6 Overlay

Container specific parameters passed at runtime. The format is <external>:<internal> (e.g. -p 443:22 maps the container's port 22 to the host's port 443).
