# Apollo Router 开发态启动脚本
#
# 与 entrypoint.sh 的差异：
# - 跳过子图等待（子图已在 host 上运行）
# - 使用 dev-supergraph.yaml（host.docker.internal）
# - 容器需 --add-host=host.docker.internal:host-gateway
#
# 使用：
#   docker run -d --name edu-apollo-router \
#     --add-host=host.docker.internal:host-gateway \
#     -p 3000:3000 -p 8088:8088 \
#     -v $(pwd)/dev-supergraph.yaml:/dist/supergraph.yaml \
#     -v $(pwd)/dev-entrypoint.sh:/dist/entrypoint.sh \
#     -v $(pwd)/router.yaml:/dist/configuration.yaml \
#     -e ROUTER_AUTH_SECRET=dev-router-secret \
#     -e APOLLO_ELV2_LICENSE=accept \
#     ghcr.io/apollographql/router:v1.45.0 \
#     /dist/entrypoint.sh
