## Compose sample application
|
||
### Java Spark application with MySQL database
|
||
|
||
Project structure:
|
||
```
|
||
.
|
||
├── backend
|
||
│ ├── Dockerfile
|
||
│ └── ...
|
||
├── db
|

```
|

|
||
[_docker-compose.yaml_](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.
|
||
|
||
> ℹ️ **_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
|
||
Building backend
|
||
...
|
||
Successfully tagged sparkjava-mysql_backend:latest
|
||
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
|
||
ee1e4f05d9f6 sparkjava-mysql_backend "/bin/sh -c 'java -j…" 44 seconds ago Up 43 seconds 0.0.0.0:8080->8080/tcp sparkjava-mysql_backend_1
|
||
716025ddf65b mysql:8.0.19 "docker-entrypoint.s…" 44 seconds ago Up 43 seconds 3306/tcp, 33060/tcp sparkjava-mysql_db_1
|
||
```
|
||
|
||
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
|
||
```
|
||
$ docker-compose down

||
