# sync-server-image.sh — build or push the mtgc sync server's container image.
#
# The image is tagged ${DOCKER_REGISTRY}/mtgc/sync-server:${IMAGE_TAG}.
# The image is tagged ${IMAGE_REPO}:${IMAGE_TAG}, by default the Docker Hub
# repository docker.io/glmdev/mtgc:latest.
#
# Usage:
# DOCKER_REGISTRY=registry.example.com ./scripts/sync-server-image.sh build
# DOCKER_REGISTRY=registry.example.com ./scripts/sync-server-image.sh push
# ./scripts/sync-server-image.sh build
# ./scripts/sync-server-image.sh push
#
# Or through npm: `npm run sync-server:build` / `npm run sync-server:push`.
#
# Environment:
# DOCKER_REGISTRY (required) registry host, optionally with a namespace path
# IMAGE_REPO repository to tag/push (default: docker.io/glmdev/mtgc)
# IMAGE_TAG tag to build/push (default: latest)
# CONTAINER_ENGINE docker or podman (default: docker if installed, else podman)
#
# `push` pushes what `build` produced; it doesn't rebuild. Log in to the
# registry first (`docker login "$DOCKER_REGISTRY"`).
