### **System Requirements**
| CPU | OS | RAM | DISK |
| ------ | --------- | ---- | ------ |
| 8 vCPU | Ubuntu 22 | 16GB | 500GB+ |
*The Boba BNB archival node has a size of 508GB on September 19th, 2024*
### Pre-requisite
Before starting, clean the setup then update and upgrade. Install following:
* Docker & Docker Compose
* Git
**Commands:**
```bash
sudo apt update -y && sudo apt upgrade -y && sudo apt auto-remove -y
sudo apt install docker.io docker-compose git ufw -y
```
### Set explicit default UFW rules
```bash
sudo ufw default deny incoming
sudo ufw default allow outgoing
```
### Allow SSH, HTTP and HTTPS
```bash
sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443
```
### **Setup**
Clone the `boba_legacy` repository to get started
```bash
git clone git@github.com:bobanetwork/boba_legacy.git
cd boba_community/boba_node
```
#### Setting up Environment Variable
You can locate environment files at `boba_legacy/ops/envs/` folder.
#### **dtl.env**
```bash
DATA_TRANSPORT_LAYER__SYNC_FROM_L1=true
DATA_TRANSPORT_LAYER__SYNC_FROM_L2=false

### **Start The Node**
```bash
docker-compose -f [docker-compose-file] up -d
```
### **Monitor Logs**
Use `docker logs` to monitor your boba node. The `-f` flag ensures you are following the log output
```bash
docker logs dtl -f
docker logs replica -f
```
### **Test RPC:**
```bash
curl --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'
-H "Content-Type: application/json" -X POST https://{DOMAIN}
```
#### **You should receive a result after the node is synced:**
```bash
{
"jsonrpc":"2.0",
"id":1,
"result":{HEX_VALUE}
}
```

# Agent Instructions: Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter:
```
GET https://docs.infradao.com/archive-nodes-101/bobabnb/docker.md?ask=
```
The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
