## Configuration and startup ## Configuration and startup
1. **Create Docker swarm:** 1. **Create Docker swarm:**
The following part is for **users** and not the development team. The development team uses a script which sets up a local development swarm.
The generated computational workload is handled by a [Docker](https://docs.docker.com/) swarm. A swarm is a group of machines that are running Docker and joined into a cluster. It consists out of two different kinds of members, managers and workers. Currently it is not possible to specify a dedicated Docker host, instead Opaque expects the executing system to be a swarm manager of a cluster with at least one dedicated worker machine. The swarm setup process is described best in the [Docker documentation](https://docs.docker.com/engine/swarm/swarm-tutorial/).

The dev team can use dind_swarm_setup.sh. If the workers cannot join the manager node. Try opening the following ports using the ubuntu firewall ufw:
```bash
sudo ufw allow 2376/tcp \
&& sudo ufw allow 7946/udp \
&& sudo ufw allow 7946/tcp \
&& sudo ufw allow 80/tcp \
&& sudo ufw allow 2377/tcp \
&& sudo ufw allow 4789/udp
sudo ufw reload && sudo ufw enable
sudo systemctl restart docker
```

The dind_swarm_setup.sh script handles this step for the dev team aswell.
A shared network space is necessary so that all swarm members have access to all the data. To achieve this a [Samba](https://www.samba.org/) can be used.
