Our servers are described in this part of the documentation.
The application runs our server at nine.ch and can be found here. Direct access to the server for deployments or configurations is accomplished through SSH with key based authentication. The TLS certificate is provided by Let’s Encrypt and automated with the certbot.
The CI process is implemented with CircleCi, which provides continues integration as a service. The link to our project can be found here (access limited to contributers of the trckr application).
