# 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}.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# DOCKER_REGISTRY=registry.example.com ./scripts/sync-server-image.sh build
|
||
|
|
# DOCKER_REGISTRY=registry.example.com ./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_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"`).
