## Compose sample

version: "3.7"

services:
|
|
web:
|
|
build: angular
|
|
ports:
|
|

|
|
...
|
|
|
|
```
|
|
The compose file defines an application with one service `angular`. The image for the service is built with the Dockerfile inside the `angular` directory (build parameter).
|
|
|
|
When deploying the application, docker-compose maps the container port 4200 to port 80 of the host as specified in the file.
|
|
Make sure port 80 is not being used by another container, otherwise the port should be changed.
|
|
|
|
|
|
## Deploy with docker-compose
|
|
|
|
```
|
|
$ docker-compose up -d

## Expected result
|
|
|
|
Listing containers must show a container running and the port mapping as below:
|
|
```
|
|
$ docker ps
|
|
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
|
|
6884c228388e angular_web "docker-entrypoint.s…" 42 seconds ago Up 36 seconds 0.0.0.0:80->4200/tcp angular_web_1
|
|
|
|
```
|
|
|
|
After the application starts, navigate to `http://localhost:80` in your web browser.
|
|
|
|
|
|
|
|
Stop and remove the container
|
|
|
|
```
|
|
$ docker-compose down
|
|
```
