# gitea-updater
This script checks if Gitea is up to date, updates it if necessary and sends a message to a Telegram bot.

## Introduction
The trap to avoid when installing custom software is to update it. It seems obvious but it is never very easy because there is often a compilation part, interoperability management between bricks, backups and so on.

## Requirements

### Software
It is clearly necessary to have deployed a Gitea instance on your server. I wrote an article about this topic here: https://illuad.fr/2020/08/01/install-a-gitea-server.html

Since a message is sent to a Telegram bot, it is necessary to have one configured. I wrote an article about this topic here: https://illuad.fr/2020/10/27/get-a-telegram-alert-on-a-ssh-login-with-pam.html

### System
This script can run on any GNU/Linux machine.

This script uses `curl` and `restorecon` commands but if you have followed my article, some of them are required which means they will necessarily be installed.

## Installation
Since this script must be executed with root rights, it is a good practice to place it in `/usr/local/sbin/`.

```
curl -LOsSf https://gitea.illuad.fr/adrien/gitea-updater/raw/branch/master/gitea-updater
sudo mv gitea-updater /usr/local/sbin
sudo chmod 750 /usr/local/sbin/gitea-updater
```

Create the logs' directory.

```
sudo mkdir -p /var/log/updater/gitea-updater
```

## Configuration
This script requires the configuration of 2 variables to work: `key` and `chat_id`.

Variables `key` and `chat_id` correspond to the API key and the chat id obtained during the bot creation process.

#### Fast variables setting
For the `key` variable.

```
sudo sed -i "s/key=/key=<your_key>/" /usr/local/sbin/gitea-updater
```

For the `chat_id` variable.

```
sudo sed -i "s/chat_id=/chat_id=<your_chat_id>/" /usr/local/sbin/gitea-updater
```

## Automation
Running this script automatically is a good idea, here is what you should have in the cron jobs of the root user.

```
sudo crontab -l
0 1 * * * /usr/local/sbin/gitea-updater
```

Every day at 1:00 am, the script will check if the Gitea is up to date.
