# peo4c: neo4j-browser on top of PostgreSQL + Apache AGE.
#
# Stage 1 builds the neo4j-browser static frontend from source.
# Stage 2 is the Apache AGE image (PostgreSQL with the AGE extension) plus the
# peo4c bridge, which speaks the Bolt protocol to the browser and translates
# Cypher into AGE `cypher()` calls, and pgAdmin as a SQL interface.

ARG AGE_IMAGE=docker.io/apache/age:release_PG18_1.8.0
# Commit of apache/age's release/PG18/1.8.0 branch, for AGE's LICENSE and NOTICE.
