classroomio/docker-compose.images.yaml

# ClassroomIO — pull-based stack (pre-built images, no local build).
#
# This is the same topology as docker-compose.yaml but the app services pull
# published images from Docker Hub instead of building from source. You only need
# THIS file + a .env — no repository checkout, no 8 GB dashboard build.
#
#   CIO_VERSION=1.4.2 docker compose -f docker-compose.images.yaml --env-file .env pull
#   CIO_VERSION=1.4.2 docker compose -f docker-compose.images.yaml --env-file .env up -d
#
# CIO_VERSION pins the release. Use a specific version (e.g. 1.4.2) in production;
# "latest" = freshest main build (moves on every merge — rolling, may include unreleased code).
#
# KEEP IN SYNC with docker-compose.yaml: the api/dashboard/jobs `environment`,
# healthchecks, depends_on, and volumes must match the build-based file. The only
# intended difference is build: -> image:.
