Scripts for running d-voting

This is a repo with some bare scripts to show how to start, initialize, and handle nodes. They are not at all prepared in any way but come straight from the server.

Starting

To start the nodes, we use the following two docker-compose files:

• docker-compose.yml for the backend, the frontend, and node #1
• docker-compose-3nodes.yml for the three nodes

All docker-compose files depend on a working traefik which is capable of handling the TLS connections and forwards it to the nodes. Please adjust the names in the docker-compose files and in the .env to correctly reflect your infra.

In addition, the nodes need a .env file, which is similar to env.example. Look at the env.example file for more information.

Initializing

To initialize, I use a couple of scripts in the init directory:

• 1-add_admin.sh run only on the backend/frontend server. It initializes the authorization management system
• 2-export-key.sh run on all workers
• 3-setup-members.sh run on dela-worker-1. Put all the keys from 2-export-key.sh as arguments
• 4-get-identity.sh run on all workers
• 5-authorize-identities.sh run on all workers. Put all the identities from 4-get-identity.sh as arguments
• 6-update-access-contract.sh run on dela-worker-1. Put all the identities from 4-get-identity.sh as arguments
• 7-add-proxy.sh run only on frontend server

Running nodes

As all the docker-compose files store the data in the data/ directories, there are some simple scripts to handle that data:

• save.sh takes a word as argument, stops docker, copies data to data.$1
• reset.sh takes a word as argument, stops docker, deletes data, copies data.$1 to data and restarts docker
• cycle.sh stops docker, pulls updates for images, and starts docker
