## Compose sample application
|
|
### Spark Java
|
|
|
|
Project structure:
|
|
```
|
|

[_docker-compose.yaml_](docker-compose.yaml)
|
|
```
|
|
version: "3.7"
|
|
services:
|
|
sparkjava:
|
|
build: sparkjava
|
|
ports:
|
|
- 80:8080
|
|
```
|
|
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 80 of the host as specified in the file.
|
|
Make sure port 80 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
|
|
5af94cb25394 sparkjava_sparkjava "/bin/sh -c 'java -j…" 20 seconds ago Up 19 seconds 0.0.0.0:80->8080/tcp sparkjava_sparkjava_1
|
|
```
|
|
|
|
After the application starts, navigate to `http://localhost:80` in your web browser or run:
|
|
```
|
|
$ curl localhost:80
|
|
Hello world
|
|
```
|
|
|
|
Stop and remove the containers
|
|
```
|
|
$ docker-compose down
|
