Docker Compose with Spring Boot CRUD API container, MySQL, NGINX as Reverse Proxy

What you will build

• You will build a simple Spring Boot CRUD API for Notes-Taking Application with a backend MySQL DB and NGINX setup as a reverse proxy server running inside Docker containers.

Getting Started

These instructions will give you a copy of the project up and running on your local machine.

Prerequisites

• Docker CE - Please read Install Docker Desktop for Windows
• REST API Client - Please read Download Postman for Windows

Running the Application

• Clone the application

git clone https://github.com/rajithatapattu/spring-boot-app-with-db-nginx.git

• Run the Application

> docker-compose up -d
Creating spring-boot-app-with-db-nginx_mysql-standalone_1 ... done
Creating spring-boot-app-with-db-nginx_easy-notes-app_1   ... done
Creating prod-nginx                                       ... done
>

The app will start running at http://localhost:7070

NOTE: I have created 2 Docker container images. One with NGINX configurations and the other with the Spring Boot Application. They are uploaded to https://hub.docker.com/ and are public. How to build them can be found at the end of Readme file

rajithdocker/nginx:3.0
rajithdocker/easy-notes:1.0

Exploring and Testing the APIs

• The Application will define the following CRUD APIs and you can test them using postman or any other REST API clients

Create a new Note using POST
POST /api/notes

Retrieving all Notes using GET 
GET /api/notes

Retrieving a single Note using GET
GET /api/notes/{noteId}

Updating a Note using PUT
PUT /api/notes/{noteId}

Deleting a Note using DELETE
DELETE /api/notes/{noteId}

Creating a new Note using POST /api/notes API

Retrieving all Notes using GET /api/notes API

Retrieving a single Note using GET /api/notes/{noteId} API

Updating a Note using PUT /api/notes/{noteId} API

Deleting a Note using DELETE /api/notes/{noteId} API

Additional Notes:

How to build the NGINX and Application container images:

 * Nginx Container Image
   Spin up a container using nginx image at Docker Hub and replace the /etc/nginx/conf.d/default.conf with the default.conf file provided in the project and create an image.

 * Spring Boot Application Container Image
   Use the Dockerfile provided in the project to create the application container image
