This container is designed to run as a non-root user

I have a label for Watchtower, that can obviously be removed or edited to your own needs.

ENVIRONMENT VARIABLES

LOG_FILE:

      • Comma-separated list, without spaces, of files to livetail. If your directories or filenames have spaces you will need to include " " around the list

      • e.g. LOG_FILE: "/var/log/sample.log,/var/log/sample log file.txt,/var/log/my container/logfile.log"
      • e.g. LOG_FILE: "/var/log/sample log file.txt"
      • e.g. LOG_FILE: /var/log/sample.log

      • If multiple files are used it will show the name each time it is different from the last message

==> /var/log/sample.log <==
2023-03-20 @ 00:37:00
==> /var/log/cron.log <==
crond: wakeup dt=60

DISCORD_WEBHOOK:

      • To send notifications to a channel go into the channel & Edit Channel

      • Select Integrations

      • Select Webhooks

      • Create a New Webhook

      • Go into the webhook settings & give it a name, avatar, whatever you like. Then click Copy Webhook URL

      • Paste that URL in the compose

  • If the webhook URL is not reachable the container will show as Unhealthy

FILTER_BY_WORD:

      • If you only want to send lines that have the word "error" or "taco" in them you can specify that here.

      • If nothing is set it will include every new line added to the file after the container started.

      • e.g. FILTER_BY_WORD: "error"
      • e.g. FILTER_BY_WORD: "2023"
      • e.g. FILTER_BY_WORD: "complete"
      • e.g. FILTER_BY_WORD: "taco"

I have included the image: calls for both Docker Hub & (commented out) for this GitHub Package. As it looks nicer, sorts nicer, & is easier to upload & manage, the Docker Hub one is my preferred method & will always get updated 1st, but I'll try to make sure this one happens right after & any changes are updated here.
