Compose sample application

Go server with an Nginx proxy and a MySQL database

docker-compose.yaml

services:
  backend:
    build: backend
    ...
  db:
    # We use a mariadb image which supports both amd64 & arm64 architecture
    image: mariadb:10.6.4-focal
    # If you really want to use MySQL, uncomment the following line
    #image: mysql:8.0.27
    ...
  proxy:
    build: proxy
    ports:
    - 80:80
    ...

The compose file defines an application with three services proxy, backend and db. When deploying the application, docker-compose maps port 80 of the proxy service container to port 80 of the host as specified in the file. Make sure port 80 on the host is not already being in use.

INFO
For compatibility purpose between AMD64 and ARM64 architecture, we use a MariaDB as database instead of MySQL.
You still can use the MySQL image by uncommenting the following line in the Compose file
#image: mysql:8.0.27

Deploy with docker-compose

$ docker-compose up -d

Expected result

Listing containers must show three containers running and the port mapping as below:

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                  NAMES

After the application starts, navigate to http://localhost:80 in your web browser or run:

$ curl localhost:80

Stop and remove the containers

$ docker-compose down
