## Compose sample ### Angular service Project structure: ``` . ├── angular │   ├── Dockerfile │   ├── ... │   ├── ... │   .... └── docker-compose.yaml ``` [_docker-compose.yaml_](docker-compose.yaml) ``` version: "3.7" 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 Creating network "angular_default" with the default driver Building angular Step 1/7 : FROM node:10 10: Pulling from library/node c0c53f743a40: Pull complete ... ... Successfully built efea5cef6851 Successfully tagged angular_web:latest WARNING: Image for service web was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`. Creating angular_web_1 ... done ``` ## 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. ![page](output.jpg) Stop and remove the container ``` $ docker-compose down ```
