I accidentally edited the wrong `README`, which was the inner one from the app generated by Angular CLI rather than the project one about Compose. Restored the old one and moved the dev envs info to the root/Compose README. Signed-off-by: Milas Bowman <milas.bowman@docker.com>

## Compose sample
|
|
### Angular service
|
|
|
|
Project structure:
|
|
```
|
|
.
|
|
├── angular
|
|
│ ├── Dockerfile
|
|
│ ├── ...
|
|
│ ├── ...
|
|

|
|
└── compose.yaml
|
|
```
|
|
|
|
[_compose.yaml_](compose.yaml)
|
|
```
|
|
services:
|
|
web:
|
|
build: angular
|
|
ports:
|
|
- 4200:4200
|
|
...
|
|
|
|
```
|
|
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 the same port on the host as specified in the file.
|
|
Make sure port 4200 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 0.0.0.0:4200->4200/tcp angular_web_1
|
|
|
|
```
|
|
|
|
After the application starts, navigate to `http://localhost:4200` in your web browser.
|
|
|
|
|
|
|
|
Stop and remove the container
|
|
|
|
```
|
|
$ docker compose down
|
|
```
|
|
|
|
## Use with Docker Development Environments
|
|
|
|
You can use this sample with the Dev Environments feature of Docker Desktop.
|
|
|
|
|
|
|
|
To develop directly on the services inside containers, use the HTTPS Git url of the sample:
