Question

我正在尝试将10个容器的解决方案部署到docker swarm中。尽管我的一个远程客户端有问题，但它在我的产品和测试服务器上都可以正常工作。

特别是在我运行命令时：

docker stack deploy --compose-file=docker-compose.yml smdr

我收到一个非常奇怪的错误消息。

_smdrnetworkwork smdr
failed to create network smdrnetwork: Error response from daemon: rpc error: code = InvalidArgument desc = name must be valid as a DNS name component

无论我如何尝试，我都无法在Google中找到这个。网络的名称是smdrnetwork，它是有效的DNS名称。但是，正如您在第一行中看到的那样，该名称显示为乱码，我觉得有些东西没有被正确地解析。

docker -v
Docker version 18.03.1-ce, build 9ee9f40

我已经将Docker从18.6降级到18.03，但是在这两个版本的docker上我的本地产品服务器上都可以正常工作。 Ubuntu 16.4作为服务器。这是我的yaml
