Notification when a container was updated

[grannymaster]

This might be a dumb question, but I can't seem to find a way to enable a notification when container X has been updated while using Discord webhook. The notification about available updates works just fine.

Not a dumb question at all - you're correct, there's no notification when a container has successfully updated, the notification is only sent for available updates.

[grannymaster]

I would assume so; if there is an update and you have auto-update on, the notification for update availability technically would serve as "container has been updated" notification also, but this assumes nothing went wrong.

Indeed you're correct.
You'll get the notifications prior to the update being run, so as @grannymaster states - no info about eventual failure.

I'll need to have a think about how to address this. Like I've mentioned above or with an extra notification if there's an error or something.

I'm mainly thinking about having a history of changes, I don't often need know what was updated and when, but sometimes when stuff brakes, it's handy info to have.

This sounds like you are asking for logging which could indeed be useful. Possible fields:

Date/Time, Container Name, Update Success/Failure

Notifications about updates seems redundant.
If I keep getting notifications about a pending update I know the container hasn't been updated.
If I stop getting notifications about a pending update I know the container has been updated.

Logs could actually be nice to see what happened when.

I kinda achieved what I wanted with a little bash script :D

#!/bin/bash

{
  echo "$(date "+%Y-%m-%d %H:%M:%S")"
  sudo /home/manager/.local/bin/dockcheck.sh -i -p -y
} >> /home/manager/dockerupdatelog.log 2>&1

Thank you for reporting back, I'll need to consider some different ways of logging, both for debugging and for history of what's done. I've added it to my list but will not prioritize it currently.
