## Introduction

We present the steps to deploy a network instance of the TFGrid on a full VM. 

For this guide, we will be deploying a mainnet instance. While the steps are similar for testnet and devnet, you will have to adjust your deployment depending on which network you use.

## Prerequisites

For this guide, you will need to deploy a full VM on the ThreeFold Grid with at least the following minimum specs:

- IPv4
- IPv6
- 32GB of RAM
- 1000 GB of SSD
- 8 vcores

After deploying the full VM, take note of the IPv4 and IPv6 addresses to properly set the DNS records and then SSH into the VM.

## DNS Settings

You need to set an A record for the IPv4 address and an AAAA record for the IPv6 address with a wildcard subdomain.

The following table explicitly shows how to set the A and AAAA records for your domain.

| Type | Host | Value          |
| ---- | ---- | -------------- |
| A    | \*   | <ipv4_address> |
| AAAA | \*   | <ipv6_address> |


### DNS Verification

You can use tools such as [DNSChecker](https://dnschecker.org/) or [dig](https://linux.die.net/man/1/dig) on a terminal to check if the DNS propagadation is complete.

## Prepare the VM

- Download the ThreeFold Tech `grid_deployment` repository
    ```
    git clone https://github.com/threefoldtech/grid_deployment
    cd grid_deployment/docker-compose/mainnet
    ```
- Generate a TFChain node key with `subkey`
    ```
    echo .subkey_mainnet >> .gitignore
    ../subkey generate-node-key > .nodekey_mainnet
    cat .nodekey_mainnet
    ```
- Create and the set environment variables file
    ```
    cp .secrets.env-example .secrets.env
    ```
- Adjust the environment file
    ```
    nano .secrets.env
    ```
- To adjust the `.secrets.env` file, take into account the following:
  - **DOMAIN**="example.com"
    - Write your own domain
  - **TFCHAIN_NODE_KEY**="abc123"
    - Write the output of the command `cat .nodekey_mainnet`
  - **ACTIVATION_SERVICE_MNEMONIC**="word1 word2 ... word24"
    - Write the seed phrase of an account on mainnet with at least 10 TFT in the wallet
  - **GRID_PROXY_MNEMONIC**="word1 word2 ... word24"
    - Write the seed phrase of an account on mainnet with at least 10 TFT in the wallet and a registered twin ID\*

> \*Note: If you've created an account using the ThreeFold Dashboard on mainnet, the twin ID is automatically registered.

## Set the Firewall

You can use UFW to set the firewall:

```
ufw allow 80/tcp
ufw allow 443/tcp
ufw allow 30333/tcp
ufw allow 22/tcp
ufw enable
ufw status
```

## Launch the Script

Once you've prepared the VM, you can simply run the script to install the grid stack and deploy it online.

```
sh install_grid_bknd.sh
```

This will take some time since you are downloading the whole mainnet grid snapshots.

## Access the Grid Services

Once you've deployed the grid stack online, you can access the different grid services by usual the usual subdomains:

```
dashboard.your.domain
metrics.your.domain
tfchain.your.domain
graphql.your.domain
relay.your.domain
gridproxy.your.domain
activation.your.domain
stats.your.domain
```

## Manual Commands

Once you've run the install script, you can deploy manually the grid stack with the following command:

```
docker compose --env-file .secrets.env --env-file .env up -d
```

You can also check if the environment variables are properly set:

```
docker compose --env-file .secrets.env --env-file .env config
```

If you want to see the output during deployment, remove `-d` in the command above as follows:

```
docker compose --env-file .secrets.env --env-file .env up
```

This can be helpful to troubleshoot errors.

## Update the Deployment

Go into the folder of the proper network, e.g. mainnet, and run the following commands:

```
git pull -r
docker compose --env-file .secrets.env --env-file .env up -d
```
