# Build Imágenes desde docker-compose

Se pueden crear imágenes desde un `docker-compose.yml` .

```
verison: '3'
services:
  web:
    container_name: web
    image: web-test
    build:  .
```

Cuando tenemos un nombre de Dockerfile personalizado ...

```
verison: '3'
services:
  web:
    container_name: web
    image: web-test
    build:
      context: .
      dockerfile: Dockerfile_name1
```

Donde `Dockerfile_name` sería el nombre de nuestro dockerfile. Y en `context` definimos la ruta con el `.` indica en el mismo directorio.

## Ejecutar docker-compose.yml con un build

```
docker-compose build
```
