Description

A very simple python script to update your pi-hole without having to change DNS everytime All the script does is:

• Pulls down latest pi-hole image
• Pulls and saves latest image
• Checks for latest image
• Purges all your docker container, images, volumes and networks to give you a clean slate (I ll remove that soon)
• Rebuilds the pi-hole docker image through docker-compose
• Everything is logged with timestamps and a log UUID is produced for each run

For now, if you don't want to purge everything, you can just remove clean_docker(client) at line 54

Note: If your pi-hole data is in a file system (like by default), you will NOT loose all your data If you are really worried once you do the initial setup backup your pi-hole data by going to: Settings -> Teleporter -> Backup in your pi-hole

Hope you enjoy!

Paste in this:

#!/bin/sh

Use this to get your cron schedule: Crontab Guru

Then to add it to crontab:

* * * *_your_run_schedule your_path_to_job/pi_job.sh >> your_log_preferred_path/pi_job.log  2>&1

This will log all output, the python script logs all output with timestamps

Warning: Test it first! Depending on what distro and how you are running cron you might want to change with chmod the folder cloned permissions
