#### Создаем окружение:

```bash
mkdir -p /nodes/btc
```

```bash
cd /nodes/btc
```

#### Создаем дерикторию с данными bitcoind:

```bash
mkdir bitcoin_data
```

#### Создаем конфигурацию bitcoind:

```bash
nano bitcoind.conf
```

{% code title="bitcoind.conf" %}

```yaml
[main]
rpcallowip=0.0.0.0/0 # !ALLOWED IP!
rpcbind=0.0.0.0
rpcport=8332
rpcuser=YOUR_USER_NAME
rpcpassword=YOUR_PASSWORD
server=1
#txindex=1
prune=2048 #2GB
datadir=/data/.bitcoin
keypool=2000
```

{% endcode %}

#### Создаем docker-compose.yml

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

{% code title="docker-compose.yml" %}

```yaml
x-logging:
  &default-logging
  driver: "json-file"
  options:
    max-file: "1"
    max-size: "500m"

services:
  bitcoin:
    image: rg.boxexchanger.net/boxexchanger-utils/docker-bitcoind:main
    container_name: bitcoind
    volumes:
      - ./bitcoin_data:/data/.bitcoin
      - ./bitcoind.conf:/data/bitcoind.conf

    restart: unless-stopped
    stop_grace_period: 15m30s
    ports:
      - "8333:8333"
      - "127.0.0.1:8332:8332"
```

{% endcode %}

#### Запускаем bitcoind в docker: 

```bash
docker compose up -d
```

{% endtab %}

{% tab title="Sources" %}

#### CMD:

```bash
sudo ufw allow 8332
mkdir /nodes
mkdir /nodes/BTC
sudo apt update
sudo apt install supervisor
```

#### /nodes/BTC/bitcoin.conf

```ini
[main]
rpcallowip=0.0.0.0/0 # !ALLOWED IP!

```

#### CMD: 

```bash
sudo supervisorctl start bitcoind
sudo supervisorctl stop bitcoind
curl -#o /tmp/bitcoin.tar.gz https://bitcoin.org/bin/bitcoin-core-25.0/bitcoin-25.0-x86_64-linux-gnu.tar.gz
tar -xf /tmp/bitcoin.tar.gz -C /tmp/
cp /tmp/bitcoin-25.0/bin/bitcoind /usr/local/bin/bitcoind
rm -r /tmp/bitcoin-25.0
rm /tmp/bitcoin.tar.gz
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start bitcoind
```

{% endtab %}
{% endtabs %}

### Открываем порт доступа

Создаем прокси с портов \
  \- localhost:8332 на порт **8233** для bitcoind rpc 

<details>

<summary>Настраиваем прокси на caddy</summary>

Устанавливаем caddy <https://caddyserver.com/docs/install>\
\
Документация подготовлена для операционной системы **Debian, Ubuntu**

```shell
apt install -y debian-keyring debian-archive-keyring apt-transport-https
```

```shell
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
```

```shell
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' |  tee /etc/apt/sources.list.d/caddy-stable.list
```

```shell
apt update
```

```shell
apt install caddy
```

конфигурируем caddy  для прокси \
8332 на порт 8233 для внешней сети&#x20;

```bash
nano /etc/caddy/Caddyfile
```

{% code title="/etc/caddy/Caddyfile" %}

```nginx

:8233 {
  handle_path /* {
    reverse_proxy 127.0.0.1:8332
  }
  respond 404
}

```

{% endcode %}

запускаем caddy

```bash
systemctl enable --now caddy
```

или перезагружаем если необходимо&#x20;

`systemctl restart caddy`

</details>

{% hint style="warning" %}
**Открытие порта для RPC:** Для доступа к RPC необходимо открыть порт 8233 в настройках фаервола для IP-адреса сервера, с которого будет происходить подключение.
{% endhint %}

### Доступы

**RPC:** `http://ip.host:8233/`
