# Zabbix
### 📌 Sobre o Projeto

Um compose personalizado do zabbix para instalar pacotes sem a necessidade de um re-build, neste arquivo, utilizo uma versão mais leve do sistema.

---

### 🚀 Como Usar

#### Via docker compose (Meu preferido.) / Portainer

 - Para docker-compose, crie um arquivo **docker-compose.yaml** com o conteúdo abaixo:


```yaml

```

 - Criar um arquivo chamado zabbix-init.sh com o conteudo abaixo:

```shell
#!/bin/sh
echo "[INIT] Instalando mtr no container..."
apk update && apk add --no-cache mtr
echo "[INIT] Executando entrypoint original..."
# Usa exec sem su, preservando variáveis de ambiente como DB_SERVER_HOST
exec /usr/bin/docker-entrypoint.sh /usr/sbin/zabbix_server --foreground -c /etc/zabbix/zabbix_server.conf
```

 - Após criar o arquivo execute os seguintes comandos:

```shell
chmod +x zabbix-init.sh && chmod 755 zabbix-init.sh
```

>[!TIP]
> - Garanta que todas as pastas / volumes estejam criados e com as corretas permissões configuradas.
