#!/bin/bash
##Script to update Docker container images occasionally and alert when update is done.
## This script is a helper script to automatically update Docker containers in a less aggressive way than
#+ existing solutions. It avoids database upgrades and generates its' log in a Prometheus-ready template,
#+ which enables generation of Prometheus alerts when a container is updated, or fails to update.
## The process:
#+ 1. Iterate over the primary container directory and search for Docker stacks
#+ 2. For each Docker stack found, iterate over the images and get their checksum
#+ 3. For each image found, login to docker.io and get the remote checksum
#+ (new repositories, such as quay.io and ghcr.io will be added in the future, if needed)
#+ 4. Compare the checksums. If they differ (assumed newer), pull the remote image
#+ 5. Bring the stack up with the new image
##
#+ The key outcomes of this process (container updated, failed to update, update status undetermined)
#+ Are written to a file monitored by Prometheus. Based on the code assigned to each, Prometheus
#+ sends out an alert (container xyz has been updated, etc).
#This is where containers live
