## Compose sample application
|
|
### NGINX proxy with Go backend
|
|
|
|
Project structure:
|
|
```
|
|
.
|
|
├── backend
|
|
│ ├── Dockerfile
|
|
│ └── main.go
|
|
├── compose.yaml
|
|
├── proxy
|
|
│ └── nginx.conf
|

└── README.md
|
|
```
|
|
|
|
[`compose.yaml`](compose.yaml)
|
|
```
|
|
services:
|
|
proxy:
|
|
image: nginx
|
|
volumes:
|
|
- type: bind
|
|
source: ./proxy/nginx.conf
|
|
target: /etc/nginx/conf.d/default.conf
|
|
read_only: true
|
|
ports:
|
|
- 80:80
|
|
depends_on:
|
|
- backend
|
|
|
|
backend:
|
|
build:
|
|
context: backend
|
|
target: builder
|
|
```
|
|
The compose file defines an application with two services `proxy` and `backend`.
|
|
When deploying the application, docker compose maps port 80 of the frontend service container to the same port of the host as specified in the file.
|
|
Make sure port 80 on the host is not already in use.
|
|
|
|
## Deploy with docker compose
|
|
|
|
```
|
|
$ docker compose up -d
|
|
Creating network "nginx-golang_default" with the default driver
|
|
Building backend
|
|
Step 1/7 : FROM golang:1.13 AS build
|
|
1.13: Pulling from library/golang
|
|
...
|
|
Successfully built 4b24f27138cc
|
|
Successfully tagged nginx-golang_proxy:latest
|
|
Creating nginx-golang_backend_1 ... done
|
|
Creating nginx-golang_proxy_1 ... done
|
|
```
|
|
|
|
## Expected result
|
|
|
|
Listing containers must show two containers running and the port mapping as below:
|
|
```
|
|
$ docker compose ps
|
|
NAME COMMAND SERVICE STATUS PORTS
|
|
nginx-golang-backend-1 "/code/bin/backend" backend running
|
|
nginx-golang-proxy-1 "/docker-entrypoint.…" proxy running 0.0.0.0:80->80/tcp
|
|
```
|
|
|
|
After the application starts, navigate to `http://localhost:80` in your web browser or run:
|
|
```
|
|
$ curl localhost:80
|
|
|

Hello from Docker!
|
|
```
|
|
|
|
Stop and remove the containers
|
|
```
|
|
$ 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:
