# Bor node
## Requirements for Polygon network
* memory: 64Gb (minimum)
* disk: 3Tb SSD (require periodically prune state)
## Installation
Set in the `.env` file:
* `DOMAIN=` - the domain name to be used in traefik;
* `HEIMDALL_ETH_RPC_URL=` - your Ethereum RPC.
You can also set a list of allowed IP addresses there and addresses to treat as local. Rename `example.env` to `.env`:
```
mv example.env .env
```
Start node:
```bash
docker-compose build
docker-compose up -d rabbitmq heimdalld heimdallr bor
```
## Upgrade
Periodically check for new versions. if there is a release, then you need to update the tag in the environment file.
```bash
docker-compose build
docker-compose pull
docker-compose up -d rabbitmq heimdalld heimdallr bor
```
## Pruning
Use it if the size is approaching 1.7Tb. At least 150 GB must be free for successful pruning.
```bash
docker-compose stop bor
docker-compose up prune-bor
docker-compose rm prune-bor
docker-compose up -d bor
```
