# Our sample application
- We will clone the GitHub repository onto our `node1`
- The repository also contains scripts and tools that we will use through the workshop

```bash
if [ -d container.training ]; then
mv container.training container.training.$$
fi

- Clone the repository on `node1`:
```bash
git clone git://github.com/jpetazzo/container.training

## Downloading and running the application
Let's start this before we look around, as downloading will take a little time...

- Go to the `dockercoins` directory, in the cloned repo:
```bash
cd ~/container.training/dockercoins
```
- Use Compose to build and run all containers:
```bash
docker-compose up
```
<!--
```longwait units of work done```
-->
]
Compose tells Docker to build all container images (pulling
the corresponding base images), then starts all containers,
and displays aggregated logs.

Some containers exit immediately, others take longer.
The containers that do not handle `SIGTERM` end up being killed after a 10s timeout.
The containers that do not handle `SIGTERM` end up being killed after a 10s timeout. If we are very impatient, we can hit `^C` a second time!
