## Compose sample application
|
||
|
|
|
||
|
|
### Java application with Spring framework and Rabbitmq
|
||
|
|
|
||
|
|
Project structure:
|
||
|
|
```
|
||
|
|
.
|
||
|
|
├── backend
|
||
|
|
│ ├── Dockerfile
|
||
|
|
│ └── ...
|
||
|
|
├── compose.yaml
|
||
|
|
└── README.md
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
[_compose.yaml_](compose.yaml)
|
||
|
|
```
|
||
|
|
services:
|
||
|
|
backend:
|
||
|
|
build: backend
|
||
|
|
ports:
|
||
|
|
- 8080:8080
|
||
|
|
rabbitmq:
|
||
|
|
rabbitmq:3.9-management
|
||
|
|
...
|
||
|
|
```
|
||
|
|
The compose file defines an application with two services `backend` and `rabbitmq`.
|
||
|
|
When deploying the application, docker compose maps port 8080 of the backend 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
|
||
|
|
86f6bb2a1585 spring-rabbitmq-backend "java -cp app:app/li…" 6 minutes ago Up 6 minutes 0.0.0.0:8080->8080/tcp spring-rabbitmq-backend-1
|
||
|
|
0c4522d3f075 rabbitmq "docker-entrypoint.s…" 6 minutes ago Up 6 minutes 4369/tcp, 5671-5672/tcp, 15691-15692/tcp, 25672/tcp spring-rabbitmq-rabbitmq-1
|
||
|
|
```
|
||
|
|
|
||
|
|
After the application starts, you can send and receive data to rabbitmq with this api :
|
||
|
|
|
||
|
|
`POST`: http://localhost:8080/sendMessage
|
||
|
|
Body:
|
||
|
|
```
|
||
|
|
{
|
||
|
|
"title":""Hello, rabbitmq",
|
||
|
|
"text":"This is my test messag",
|
||
|
|
"sender":"admin"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
`GET`: http://localhost:8080/getMessage
|
||
|
