### Docker Compose
Build container:
```bash
$ docker compose build
```
Run container:
```bash
$ docker compose up -d
```
The docker-compose binds to `127.0.0.1` by default. To expose the Stratum services on your server change:
```diff
ports:
- - "127.0.0.1:3333:3333/tcp"
- - "127.0.0.1:3334:3334/tcp"
+ - "3333"
+ - "3334"
```
**note**: To successfully connect to the bitcoin RPC you will need to add
```
rpcallowip=172.16.0.0/12
```
to your bitcoin.conf.
