# BRouter for Train's routes (ADR 0030, D11, D44, D46): its release, checked against
# GitHub's SHA-256 of it, on Eclipse Temurin's Java 17 as BRouter's own image, with
# its profiles and Train's running profile. Built from the repository root:
#
#   docker build -f deploy/brouter/Dockerfile .
#
# The same image refreshes the segments (segments.sh), so it carries curl.
FROM eclipse-temurin:17-jre-noble

# BRouter v1.7.10, released 17 Jul 2026.
