20th Fribourg Linux Seminar - From zero to production-grade service in 55 min.
4 March 2021
- 17:00 Welcome [Daniel Gachet]
- 17:05 Dokku : “Own your Paas” [Jacques Supcik]
In 2021, it is easy to host your web application with a major cloud provider. But sometimes, you don’t really need the high availability and the scalability offered by those major cloud providers, and you prefer to have everything under your control. “Dokku” is an open source software that implements a simple “Platform as a service” (Paas) and allows you to easily deploy and host your applications.
During this presentation, you will understand the benefits and the limitations of Dokku and during a live demo. We will start from zero, install a virtual machine - hosted in Switzerland - with the help of Terraform and install all required software using cloud-init scripts. Then we will implement and deploy a demo service to this newly created instance.
- 17:40 Deploying a real service to Dokku and monitoring it with Prometheus/Grafana [Lucy Linder]
Having your own “Platform as a service” (Paas) is great, but a platform is only as good as the services you deploy on it. Applications today are more and more complex, usually depending on multiple technologies and/or composed of many moving parts (backend/frontend, databases, PubSub, etc.). Moreover, once everything is running, you'll also have to ensure it stays that way.
During this presentation, you will see how to deploy a real-life application to Dokku. The application will be a REST service written in Kotlin/Spring Boot, and relying on two databases: MySQL and Cassandra. You will also get introduced to Prometheus + Grafana, a common combination of tools to build up a monitoring system (no "plot" twist here, just beautiful plots :) )
