Service management

[codeofmochi]

We will probably release the services-oriented architecture as containers on docker on our bare-metal server. However, manually managing Docker will prove cumbersome, so we should use a container orchestration runtime (this will also allow self-healing, scaling, zero-downtime updates, secrets management, ...). We could use a full-blown orchestration system such as Kubernetes, but the learning curve is tough for newcomers. Maybe we should have a look at lean deployment strategies such as Nomad: https://www.nomadproject.io/
