Compose sample application

Spark Java

docker-compose.yaml

version: "3.7"
services:
  sparkjava:
    build: sparkjava
    ports:
    - 8080:8080

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

Deploy with docker-compose

$ docker-compose up -d

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, navigate to http://localhost:8080 in your web browser or run:

$ curl localhost:8080
Hello from Docker!

Stop and remove the containers
