Hero Docker Container

Introduction

A Docker-based development environment for Hero development with essential tools and configurations. This container comes pre-installed with Bun, Redis, and the Hero CLI.

Prerequisites

• Docker installed on your system
• SSH keys for deploying Hero websites (if publishing)

Build the Image

Build the Docker image:

docker build -t hero_docker .

Run the Container

Run the container with an interactive shell, mounting your current directory as the workspace and your SSH keys:

docker run --network=host \
  -v $(pwd):/workspace \
  -v ~/.ssh:/root/ssh \
  -it hero_docker

By default, the container will:

• Start Redis server in the background
• Copy your SSH keys to the proper location
• Initialize the SSH agent
• Add your default SSH key (id_ed25519)

To use a different SSH key, specify it with the KEY environment variable (e.g. KEY=id_ed25519):

docker run --network=host \
  -v $(pwd):/workspace \
  -v ~/.ssh:/root/ssh \
  -e KEY=your_custom_key_name \
  -it hero_docker

Launch the Hero Website

To start a Hero Docusaurus website in development mode:

• Build the book then close the prompt with Ctrl+C

  hero docs -d
  

• See the book on the local browser

  bash /root/hero/var/docs/develop.sh
  

You can then view the website in your browser at https://localhost:3100.

Publish a Website

• To build and publish a Hero website:
  • Development

    hero docs -bpd
    

  • Production

    hero docs -bp
    

If you want to specify a different SSH key, use -dk:

hero docs -bpd -dk ~/.ssh/id_ed25519

Note: The container handles the SSH agent and key management automatically on startup, so in most cases, you won't need to manually specify keys.
