Compose sample application
Java application with Spring framework and Rabbitmq
Project structure:
.
├── backend
│ ├── Dockerfile
│ └── ...
├── compose.yaml
└── README.md
services:
backend:
build: backend
ports:
- 8080:8080
rabbitmq:
image: 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"
}
