# syntax=docker/dockerfile:1.4
# aldabra — Cardano lite wallet over MCP.
#
# Multi-stage:
#   1. builder — rust toolchain, cargo build --release
#   2. runtime — debian:bookworm-slim, just the binary + ca-certs.
#
# Built nightly on Lucy (see lucy-infra/scripts/nightly-builds.sh) and
# published as `lucy-registry:5000/aldabra/mcp:{SHA,latest}`. Pulled
# anywhere we want the MCP server available — usually as a sidecar
# spawned by an MCP client (Claude Code, OpenClaw).
#
# Required env at runtime:
#   ALDABRA_DATA           directory containing mnemonic.age (must
#                          already exist; bootstrap separately on
#                          first install)
#   ALDABRA_NETWORK        mainnet | preview | preprod (default preprod)
#   ALDABRA_KOIOS_BASE     defaults to public Koios for the network
#   ALDABRA_PASSPHRASE     unlocks mnemonic.age. Source from a docker
#                          secret or systemd EnvironmentFile — never
#                          commit it.
