## Compose sample application
|
||
### ASP.NET server with an Nginx proxy and a MySQL database
|
||
|
||
Project structure:
|
||
```
|
||
.
|
||
├── backend
|
||
│ ├── Dockerfile
|
||
│ ├── aspnet.csproj
|
||
│ └── Program.cs
|
||
├── db
|
||
│ └── password.txt
|
||
├── compose.yaml
|
||
├── proxy
|
||
│ ├── conf
|
||
│ └── Dockerfile
|
||
└── README.md
|
||
```
|
||
|
||
[_compose.yaml_](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.
|
||
|
||
> ℹ️ **_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
|
||
8906b14c5ad1 nginx-aspnet-mysql_proxy "nginx -g 'daemon of…" 2 minutes ago Up 2 minutes 0.0.0.0:80->80/tcp nginx-aspnet-mysql
|
||

||

|
||
l_db_1
|
||
```
|
||
|
||
After the application starts, navigate to `http://localhost:80` in your web browser or run:
|
||
```
|
||
$ curl localhost:80
|
||
["Blog post #0","Blog post #1","Blog post #2","Blog post #3","Blog post #4"]
|
||
```
|
||
|
||
Stop and remove the containers
|
||
```
|
||
$ docker compose down
|
||
```
|
