Dockerfile

# IICP Python node — runs an iicp-client provider node out of the box.
#
#   docker build -t iicp-node-py .
#   docker run --restart on-failure -p 8020:8020 \
#     -e IICP_BACKEND_URL=http://host.docker.internal:11434 \
#     -e IICP_BACKEND_MODEL=qwen2.5:0.5b \
#     -e IICP_PUBLIC_ENDPOINT=http://<your-public-ip>:8020 \
#     iicp-node-py
#
# Required env vars:
#   IICP_BACKEND_URL    — OpenAI-compatible backend (Ollama / vLLM / LM Studio)
#   IICP_BACKEND_MODEL  — model name (e.g. qwen2.5:0.5b)
#
# Optional:
#   IICP_PUBLIC_ENDPOINT — externally reachable URL of this node. If omitted,
#                          the node tries automatic reachability (Quick Tunnel
#                          first, relay last-resort) before staying local.
#   IICP_TUNNEL_DEAD_POLICY — auto|retry|exit|log-only; default auto exits when
#                          supervised so Docker can restart, manual runs retry.
#   IICP_SUPERVISED   — default 1 in this image; keep with --restart on-failure.
#   IICP_DIRECTORY_URL  — default: https://iicp.network/api
#   IICP_REGION         — default: eu-central
#   IICP_MAX_CONCURRENT — default: 4
#   IICP_NODE_ID        — auto-generated if absent
#   IICP_INTENT         — default: urn:iicp:intent:llm:chat:v1
#
# See https://iicp.network/docs/sdk-quickstart-docker for the full setup guide.
