## Compose sample application
### Use with Docker Development Environments
You can open this sample in the Dev Environments feature of Docker Desktop version 4.12 or later.

### Python/Flask application
Project structure:
```
.
├── compose.yaml
├── app
   ├── Dockerfile
   ├── requirements.txt
   └── app.py
```
[_compose.yaml_](compose.yaml)
```
services:
web:
build:
context: app
target: builder
ports:
- '8000:8000'
```
## Deploy with docker compose
```
$ docker compose up -d
[+] Building 1.1s (16/16) FINISHED
=> [internal] load build definition from Dockerfile 0.0s
... 0.0s
=> => naming to docker.io/library/flask_web 0.0s
[+] Running 2/2
⠿ Network flask_default Created 0.0s
⠿ Container flask-web-1 Started
```
## Expected result
Listing containers must show one container running and the port mapping as below:
```
$ docker compose ps
NAME COMMAND SERVICE STATUS PORTS
flask-web-1 "python3 app.py" web running 0.0.0.0:8000->8000/tcp
```
After the application starts, navigate to `http://localhost:8000` in your web browser or run:
```
$ curl localhost:8000
Hello World!
```
Stop and remove the containers
```
$ docker compose down
```
