Getting started with docker-compose.yml

These instructions will get you through the bootstrap phase of creating and deploying samples of containerized applications with Docker Compose.

Prerequisites

For work with .yml files you need to install and use Docker Desktop.

Installation instructions can be found here:

• Windows or macOS: Install Docker Desktop
• Linux: Install Docker and then Docker Compose

If you need more information, see Docker Compose docs: Docker Compose documentation

Running a sample

The root directory of each sample contains the docker-compose.yaml which describes the configuration of service components. All samples can be run in a local environment by going into the root directory of each one and executing:

docker-compose up -d --build

To stop and remove all containers of the sample application run:

docker-compose down

The compose file defines an application with two services backend and postgres. When deploying the application, docker-compose maps port 8080 of the backend service container to port 8080 of the host as specified in the file. Make sure port 8080 on the host is not already being in use.

After the application starts, navigate to http://localhost:8080/swagger-ui/ in your web browse
