agent0/bootstrap.sh

#!/usr/bin/env bash
# bootstrap.sh — one-shot setup for the Agent0 box.
#
# Run once after cloning. Handles everything that can be automated:
#   - Ollama install + model pulls
#   - SSH key generation (tunnel key + Gitea key)
#   - gutasktool clone (into agent-zero-data, mounted into the agent0 container)
#   - Docker containers (gutasktool installed inside agent0 container)
#
# After this script: add two SSH keys (printed at the end), then open
# https://agent0.glitch.university and enter your API keys in Settings.
