docker compose 工作正常，但 Docker Swarm 服务名称有下划线，这会在其他容器中产生问题

docker stack deploy --compose-file swarm-compose.yml $COMPOSE_PROJECT_NAME

docker service ls
ID             NAME                          MODE         REPLICAS   IMAGE                                 PORTS
rr677zgjqw3n   docker-trino_hive-metastore 

下划线会破坏其他服务，所以我该怎么办，要么用连字符替换下划线

Trino 容器取决于 Hive Metastore URL 的名称，但 URL 中包含下划线会产生问题。

目前您无法将

_

替换为

-

，这就是 Docker Swarm（堆栈）的工作原理。堆栈中的服务名称模式：

<stack_name>_<service_name>

.

GitHub 上的

docker/cli

项目中有开放票证：https://github.com/docker/cli/issues/3364

作为解决方法，您可以使用网络别名：https://docs.docker.com/compose/compose-file/compose-file-v3/#aliases（如果您为您的服务创建网络别名，则其他服务会根据别名找到）
