# Integrationnet - Build a Pacaswap node

## System Requirements

To run a Metagraph Validator Node, ensure your machine meets the following minimum requirements:

* Memory (RAM):
  * Minimum: 8 GB
  * Recommended: 16 GB or more for optimal performance
* Storage:
  * At least 100 GiB of SSD storage
* CPU:
  * Minimum: 2 vCPU
  * Recommended: 4 vCPU

## Dependencies

This node runs inside a Docker container, so you’ll need the following installed on your local machine or cloud instance:

### **Docker Engine**

Ensure Docker is installed and running. Installation instructions can be found in the official documentation:

👉 [Docker Engine Install Guide](https://docs.docker.com/engine/install/)

### **Docker Compose**

Docker Compose is required to manage multi-container setups. You can install it by following this guide:

👉 [Docker Compose Install Guide](https://docs.docker.com/compose/install/)

### **Java**

Java is required to run the JARs. You can install it by following this guide:

👉 [Java Install Guide](https://www.java.com/en/download/manual.jsp)

## `.p12` File and Node ID

Before proceeding, you need to create a `.p12` file and get your Node ID so we can add you to the seed list.

**1.1 Download the required tools**

Download the following files from the latest Tessellation release:

* `cl-keytool.jar`
* `cl-wallet.jar`

🔗 You’ll find them under **Assets** here:\
👉 [Tessellation Releases on GitHub](https://github.com/Constellation-Labs/tessellation/releases)

**1.2 Set your environment variables**

```bash
export CL_KEYSTORE="my_node.p12"
export CL_KEYALIAS="my_node"
export CL_PASSWORD="your_secure_password"
```

**1.3 Generate your `.p12` file**

```bash
java -jar cl-keytool.jar generate
```

**1.4 Get your Node ID**

```bash
java -jar cl-wallet.jar show-id
```

**1.5 Share your Node ID**

Tag the team on Discord and send your Node ID so it can be added to the seed list.

> ⚠️ **Only proceed to the next step after your Node ID has been confirmed in the seed list.**

## **Installation**

To install and run a Metagraph validator node, follow the steps below:

**1. Create your working directory**

```bash
mkdir my-node
cd my-node
```

**2. Create the shared-data directory with the metagraph-l0 subdirectory**

```bash
mkdir -p shared-data/metagraph-l0
```

**3. Copy your .p12 keystore file into this directory**

{% hint style="warning" %}
If you haven’t created a `.p12` file yet, follow the official guide:\
\
[Working with .p12 files](https://docs.constellationnetwork.io/metagraph-development/guides/working-with-p12-files)
{% endhint %}

```bash
cp /path/to/your/file.p12 shared-data/metagraph-l0/
```

**4. Return to the root of your  my-node directory** Ensure you’re back in my-node before the next steps:

```bash
cd my-node
```

**5. Create a docker-compose.yml file**

Use the appropriate template for your network (e.g. docker-compose.integrationnet.yml) and paste it into a new file:

```bash
nano docker-compose.yml
```

{% file src="/files/LHvI5AIM2Fk9HFVBFDrh" %}

**6. Create a .env file** Use the corresponding .env template (e.g. .env.integrationnet) and paste it into a new file:

```bash
nano .env
```

{% file src="/files/liMwlSXO7WHY1JaxTHim" %}

**7. Edit the .env file with your node’s configuration**

Make sure to update the following values:

* NODE\_IP: Your instance’s public IP
* METAGRAPH\_L0\_CL\_KEYSTORE: Full path to your .p12 file (e.g. /app/shared-data/metagraph-l0/my\_file.p12)
* METAGRAPH\_L0\_CL\_KEYALIAS: Your keystore alias (e.g. my\_file)
* METAGRAPH\_L0\_CL\_PASSWORD: Your keystore password (e.g. my\_password)

**8. Verify your folder structure**

Your my-node directory should now contain:

```bash
my-node/
├── docker-compose.yml
├── .env
└── shared-data/
    └── metagraph-l0/
        └── your_file.p12
```

**9. Start your node 🚀** Run the following command to bring your node up:

```bash
docker-compose down && docker-compose pull && docker-compose up -d && docker-compose logs -f
```

This command will:

*  Stop any running container
*  Pull the latest image
*  Start the node in detached mode
*  Stream the logs
