## Introduction

We provide the steps to prepare a Docker Ubuntu container to work with Hero and Crystallib.

## Prerequisites

- Docker

## Deploy Webserver

- Run the Ubuntu container with host networking and a specific name
```
sudo docker run -it --net=host --name=hero-container -v ~/code:/root/code ubuntu:latest /bin/bash
```

- If you want to set up the SSH key, do the following:
   - Create Directory .ssh in container
   ```
   mkdir -p ~/.ssh
   ```
   - Copy SSH keys to container from local machine (use the proper path and key type)
   ```
   sudo docker cp ~/.ssh/id_ed25519 hero-container:/root/.ssh/id_ed25519
   sudo docker cp ~/.ssh/id_ed25519.pub hero-container:/root/.ssh/id_ed25519.pub
   ```
- Execute all commands directly in the container

```
# Install prerequisites
export DEBIAN_FRONTEND=noninteractive
apt-get update -y
apt-get install -y git curl nano openssh-client libsqlite3-dev python3-venv

# Clone the repository and set up the environment

mkdir -p ~/code/github/freeflowuniverse
cd ~/code/github/freeflowuniverse
git clone https://github.com/freeflowuniverse/crystallib
cd crystallib

# Download and run installation scripts for Crystallib and Hero

curl https://raw.githubusercontent.com/freeflowuniverse/crystallib/development/scripts/install_hero.sh > /tmp/hero_install.sh

bash /tmp/hero_install.sh

curl https://raw.githubusercontent.com/freeflowuniverse/crystallib/development/scripts/installer.sh > /tmp/install.sh

bash /tmp/install.sh

echo
echo "Crystallib and Hero are set up on your Docker container."
echo

```

## Clean Up

When you're done, you can clean up your environment.

```
sudo docker stop hero-container
sudo docker rm hero-container
sudo find ~/code -mindepth 1 -delete
```
