### 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
|
|
```
|
|
<br >
|
|
|
|
### 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

| `Description` | HeavyScript git pull and Update apps | This is up to you, put whatever you think is a good description in here |
|
|
| `Command` | `git -C /PATH/TO/HEAVY_SCRIPT_DIRECTORY pull && bash /PATH/TO/HEAVY_SCRIPT_DIRECTORY/heavy_script.sh -b 14 -Rsup` | This is the command you will be running on your schedule I personally use: `git -C /mnt/speed/scripts/heavy_script pull && bash /mnt/speed/scripts/heavy_script/heavy_script.sh -b 14 -Rsup` |
|
|
| `Run As User` | `root` | Running the script as `root` is REQUIRED. You cannot access all of the kubernetes functions without this user. |

| `Schedule` | Up to you, I run mine everyday at `0400` | Again up to you |
|
|
| `Hide Standard Output` | `False` or Unticked | I like to receive an email report of how the script ran, what apps updated etc. |
|
|

### Additional Informaton
|
|
|
|
#### Verbose vs Non-Verbose
|
|
- Verbose used `bash heavy_test.sh -b 5 -SRupv`
|
|
- Non-Verbose used `bash heavy_test.sh -b 5 -SRup`
|
|
|
|
| Verbose | Non-Verbose |
