Examples

Typical Cron Job

bash heavy_script.sh -b 14 -i portainer -i arch -i sonarr -i radarr -t 600 -Rsup

• -b is set to 14. Up to 14 snapshots of your ix-applications dataset will be saved
• -i is set to ignore portainer, arch, sonarr, and radarr. These applications will be ignored when it comes to updates.
• -t I set it to 600 seconds, this means the script will wait 600 seconds for the application to become ACTIVE before timing out and continuing to a different application.
• -R Will rollback applications if they fail to deploy after updating.
• -s will just sync the repositories, ensuring you are downloading the latest updates.
• -u update applications as long as the major version has absolutely no change, if it does have a change it will ask the user to update manually.
• -p Prune docker images.

Mounting PVC Data

bash /mnt/tank/scripts/heavy_script.sh -t 300 -m

Restoring ix-applications dataset

bash /mnt/tank/scripts/heavy_script/heavy_script.sh -r

My personal Cron Job

git -C /mnt/speed/scripts/heavy_script pull && bash /mnt/speed/scripts/heavy_script/heavy_script.sh -b 14 -Rsup

How to Install

Create a Scripts Dataset

I created a scripts dataset on my Truenas SCALE system, this is where all my scripts will remain.

Open a Terminal

Change Directory to your scripts folder

cd /mnt/speed/scripts

Git Clone Heavy_Script

git clone https://github.com/Heavybullets8/heavy_script.git

Change Directory to Heavy_Script folder

cd heavy_script

From here, you can just run Heavy_Script with bash heavy_script.sh -ARGUMENTS

Note: chmod +x is NOT required. Doing this will break the git pull function. Just run the script with bash heavy_script.sh

How to Update

Manually

Open a Terminal

Change Directory to your heavy_script folder

cd /mnt/speed/scripts/heavy_script

git pull

git pull

Update with your Cron Job

Here, we will update the script prior to running it, incase there is a bugfix, or any new additions to the script

Cron Job Command

git -C /mnt/speed/scripts/heavy_script pull && bash /mnt/speed/scripts/heavy_script/heavy_script.sh -b 14 -Rsup

The important command here is the git -C /PATH/TO/HEAVY_SCRIPT_DIRECTORY pull

This command will allow you to preform a git pull on a remote directory, which will ensure your script is udated prior to running it

&& Is used to run a command AFTER the previous command completed successfully

So once the git -C /PATH/TO/HEAVY_SCRIPT_DIRECTORY pull command completes, THEN it will run the bash /PATH/TO/HEAVY_SCRIPT_DIRECTORY/heavy_script.sh -b 14 -Rsup command
