|
## Prerequisites
|
|
|
|
* You have a [Git client](https://git-scm.com/downloads). The examples in this section use a command-line based Git client, but you can use any client.
|
|
|
|
## Overview
|
|
|
|
This section walks you through containerizing and running a C++ application.
|
|
|
|
## Get the sample application
|
|
|
|
Clone the sample application to use with this guide. Open a terminal, change directory to a directory that you want to work in, and run the following command to clone the repository:
|
|
|
|
```console
|
|
$ git clone https://github.com/dockersamples/c-plus-plus-docker.git
|
|
```
|
|
|
|
You should now have the following contents in your `c-plus-plus-docker`
|
|
directory.
|
|
|
|
```text
|
|
├── c-plus-plus-docker/
|
|
│ ├── compose.yml
|
|
│ ├── Dockerfile
|
|
│ ├── LICENSE
|
|
│ ├── ok_api.cpp
|
|
│ └── README.md
|
|
|
|
```
|
|
|
|
To learn more about the files in the repository, see the following:
|
|
- [Dockerfile](../../reference/dockerfile.md)
|
|
- [.dockerignore](../../reference/dockerfile.md#dockerignore-file)
|
|
- [compose.yml](../../compose/compose-file/_index.md)
|
|
|
|
## Run the application
|
|
|
|
Inside the `c-plus-plus-docker` directory, run the following command in a
|
|
terminal.
|
|
|
|
```console
|
|
$ docker compose up --build
|
|
```
|
|
|
|
Open a browser and view the application at [http://localhost:8080](http://localhost:8080). You will see a message `{"Status" : "OK"}` in the browser.
|
|
|
|
In the terminal, press `ctrl`+`c` to stop the application.
|
|
|
|
### Run the application in the background
|
|
|
|
You can run the application detached from the terminal by adding the `-d`
|
|
option. Inside the `c-plus-plus-docker` directory, run the following command
|
|
in a terminal.
|
|
|
|
```console
|
|
$ docker compose up --build -d
|
|
```
|
|
|
|
Open a browser and view the application at [http://localhost:8080](http://localhost:8080).
|
|
|
|
|
|
In the terminal, run the following command to stop the application.
|
|
|
|
```console
|
|
$ docker compose down
|
|
```
|
|
|
|
For more information about Compose commands, see the [Compose CLI
|
|
reference](../../compose/reference/_index.md).
|
|
|
|
