Docker Build Pipeline with Remote Asset Compilation

Problem

To compile code into assets/artifacts and build a Docker image with the resulting code only, and no compilers/devel packages/libraries, you have a workflow like so:

clcollins

#!/bin/bash

usage () {
  cat << EOF
Usage: dkr HOSTNAME
       dkr HOSTNAME COMMAND [arg...]

A wrapper around Docker to simplify using TLS connections

In the first form, will watch the output of "docker ps" and "docker images" on the remote host.

## Snippet of Ansible Playbook for auto-expanding a volume group based on disks on the server

  ### Format Partitions ###
  - name: Format | find disks
    command: find /dev -regex "/dev/sd[b-z]" -exec echo "{}," \;
    register: extra_pvs

  - name: Format | expand vg if extra_pvs exist
    # defaultpv comes last, because extra_pvs are formatted to have a comma on the end
