Update Arguments

Flag	Example	Parameter	Description
-U	-U -U 5	Optional Integer	Update applications, ignoring major version changes Optionally, you can supply a number after the argument to update multiple applications at once
-u	-u -u 5	Optional Integer	Update applications, do NOT update if there was a major version change Optionally, you can supply a number after the argument to update multiple applications at once
-b	-b 14	Integer	Snapshot ix-applications dataset Creates backups UP TO the number you've chosen
-i	-i nextcloud -i sonarr	String	Applications listed will be ignored during updating List one application after another as shown in the example
-r	-r		Monitors applications after they update If the app does not become "ACTIVE" after the timeout, rollback the application.
-v	-v		Verbose Output Look at the bottom of this page for an example
-S	-S		Shutdown the application prior to updating it
-t	-t 400	Integer	Time in seconds that HeavyScript will wait for an application to no longer be deploying before declaring failure Default: 500
-s	-s		Sync Catalogs prior to updating
-p	-p		Prune unused docker images
--ignore-img	--ignore-img		Ignore container image updates
--self-update	--self-update		Updates HeavyScript prior to running any other commands

Example

Cron Job

bash heavy_script.sh --self-update -b 10 -i nextcloud -i sonarr -t 600 --ignore-img -rsp -u 5

-b is set to 10. Up to 10 snapshots of your ix-applications dataset will be saved

-i is set to ignore nextcloud and sonarr. These applications will be skipped if they have an update.

-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 rolling back to the previous version since -r is used.

--ignore-img Will not update the application if it is only a container image update

-r Will rollback applications if they fail to deploy within the timeout, after updating.

-s will just sync the repositories, ensuring you are downloading the latest updates.

-p Prune docker images.

-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.

The 5 after the -u means up to 5 applications will be updating and monitored at one time

--self-update Will update the script prior to running anything else.

My Personal Cron Job

bash /mnt/speed/scripts/heavy_script/heavy_script.sh --self-update -b 10 -rsp -u 10

Other Utilities

All of these can ALSO be accessed with the HeavyScript menu, that you can access simply by not providing an argument bash heavy_script.sh

Flag	Description
--mount	Initiates mounting feature, choose between unmounting and mounting PVC data
--restore	Opens a menu to restore a heavy_script backup that was taken on your ix-applications dataset
--delete-backup	Opens a menu to delete backups on your system
--dns	list all of your applications DNS names and their web ports
--cmd	Open a shell for one of your applications

Examples

Mounting PVC Data

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

Restoring ix-applications dataset

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

Deleting Backups

bash /mnt/tank/scripts/heavy_script/heavy_script.sh --delete-backup

List All DNS Names

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

Open a Containers Shell

bash /mnt/speed/scripts/heavy_script/heavy_script.sh --cmd

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 (or self update) function. Just run the script with bash heavy_script.sh

How to Update

Built-In Option (Reccommended)

bash heavyscript.sh --self-update -b 10 -supr

The important argument here is the --self-update, you can still use all of your same arguments with this option.

--self-update will place users on the latest tag, as well as showing the changelog when new releases come out. So this is the preferred method. Not using this method, will instead place the user on main, where the changes are tested, but not as rigerously as they are on the releases.

Manually

Open a Terminal

Change Directory to your heavy_script folder

cd /mnt/speed/scripts/heavy_script

git pull

git pull

This is not recommended because the changes to main are not tested as much as the changes that are pushed to releases are tested, think of this method of updating as being in development.
