## 📦 Template Catalog (Managed Instances)

Provisioning a database template (e.g. MySQL, PostgreSQL, Redis, MongoDB):

{% stepper %}
{% step %}
Open the Templates page: <https://discloud.com/templates>
{% endstep %}

{% step %}
Choose the desired template (database engine or tooling panel).
{% endstep %}

{% step %}
Provide a name and required environment variables (the UI indicates mandatory ones).
{% endstep %}

{% step %}
Deploy. Credentials / connection strings become available for your app configuration.
{% endstep %}
{% endstepper %}

{% hint style="info" %}

#### **Need Another Template?**

Open a [support ticket](https://discord.com/channels/@me/930852077045940224/) in the [Discord server](https://discord.discloudbot.com/) with the engine name, version, and use case. The team evaluates feasibility and may add it to the catalog.
{% endhint %}

## 🌍 Using External MongoDB Atlas

If you opt for MongoDB Atlas instead of a template:

{% stepper %}
{% step %}
Create a free or paid cluster at <https://www.mongodb.com/>
{% endstep %}

{% step %}
In Network Access, add IP: `0.0.0.0/0` (Allow from Anywhere) so Discloud containers can connect.
{% endstep %}

{% step %}
Test connectivity locally before deploying if possible.
{% endstep %}
{% endstepper %}
