Compose sample application

Java Spark application with MySQL database

docker-compose.yaml

services:
  backend:
    build: backend
    ports:
    - 8080:8080
  db:
    # We use a mariadb image which supports both amd64 & arm64 architecture
    image: mariadb:10.6.4-focal
    # If you really want to use MySQL, uncomment the following line
    #image: mysql:8.0.27
    ...

The compose file defines an application with two services backend and db. When deploying the application, docker-compose maps port 8080 of the backend service container to port 80 of the host as specified in the file. Make sure port 8080 on the host is not already being in use.

INFO
For compatibility purpose between AMD64 and ARM64 architecture, we use a MariaDB as database instead of MySQL.
You still can use the MySQL image by uncommenting the following line in the Compose file
#image: mysql:8.0.27

Deploy with docker-compose

$ docker-compose up -d
Creating network "sparkjava-mysql_default" with the default driver

WARNING: Image for service backend was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.

Expected result

Listing containers must show two containers running and the port mapping as below:

$ docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                  NAMES

After the application starts, run:

$ curl localhost:8080
["Blog post #0","Blog post #1","Blog post #2","Blog post #3","Blog post #4"]

Stop and remove the containers
