# mknet
Show usage:
```help
python3 main.py
```
## Example
```bash
sudo rm -rf /tmp/garage-testnet/ # always start by deleting previous run
sudo python3 main.py create ./config.yml
sudo python3 main.py run-all example/deploy_garage.sh
sudo python3 main.py run dc1:dc1s1 garage -c /tmp/garage-testnet/dc1/dc1s1/garage.toml status
sudo python3 main.py destroy
```
## Instrumented daemons
If you want to use the scripts provided in the `example` folder,
you must add to your path some tools.
### Garage (`deploy_garage.sh`)
```bash
# see versions on https://garagehq.deuxfleurs.fr/_releases.html
export GRG_ARCH=x86_64-unknown-linux-musl
export GRG_VERSION=v0.5.0
sudo wget https://garagehq.deuxfleurs.fr/_releases/${GRG_VERSION}/${GRG_ARCH}/garage -O /usr/local/bin/garage
sudo chmod +x /usr/local/bin/garage
garage help
```
### Minio (`deploy_minio.py`)
```
sudo wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /usr/local/bin/minio
sudo chmod +x /usr/local/bin/minio
```
