Wednesday (CodeLab) - Docker, Digital Ocean, Watch Tower, and Caddy Server
Today we will finish deploying a web api on a Digital Ocean Droplet. We will use Docker, Watch Tower, and Caddy Server to deploy the web api.
The goal is to have a running web api on a Digital Ocean Droplet with a domain name and SSL certificate. The web api should be accessible through the domain name and should be updated automatically when a new version is pushed to the Docker Hub.
Prepare for the CodeLab
-
It would be good if you have a domain name ready. It takes a little while to get a domain activated and have the dns handling transfered to Digital Ocean. If you don’t have a domain name yet, please follow this tutorial.
-
Also, sign up on Digital Ocean if you haven’t done that already. Here is a tutorial.
-
Make sure you have a Droplet running on Digital Ocean. Here is a tutorial.
In-class exercises
This week’s CodeLab is a full pipeline exercise. You will set up a full CI/CD pipeline for a Java project using GitHub Actions, Docker Hub, and Watchtower. You will learn how to automate the building, testing, and deployment of your application in a containerized environment and later run it on a Digital Ocean server.
Thursday (class) - Putting the pieces together - Integration testing with Security
No preparations needed for this day. But bring your laptop ;-)
In-class exercises
- First off a premiere of the new event Architecture Bingo 2025.
- First we will go through how to setup integration testing of Javalin endpoints with security. Hotel API with tests and security. The branch called “restassured” is the one to look at. It contains a working example of how to set up integration testing for rest endpoints.
- Then we will apply the methodology to a new project. We will use this project as a base for the tests: Todos
