Question

我正在尝试将我的工作docker-compose设置部署到docker-swarm，一切似乎都没问题，除了获得复制并生成正在运行的容器的唯一服务是redis，其他3个被卡住了，从不生成任何正在运行的容器，他们甚至不会下载他们各自的图像。我无法找到任何调试功能，所有日志都是空的，我完全无能为力。让我告诉你我安装的当前状态。

docker node ls print =＆gt;

我的redis成功服务（docker service ps stack_redis）

我的mongo服务不成功（docker service ps stack_mongo）

我对docker swarm来说是全新的，可能在这里犯了一个愚蠢的错误，但我找不到很多关于如何设置这么简单的堆栈的文档。

Answer 1

要进行监控，请尝试以下操作：

journalctl -f -n10

然后在单独的会话中运行docker stack deploy命令并查看其显示内容

Answer 2

尝试删除端口发布并将--endpoint-mode dnsrr添加到您的服务中。

docker stack deploy生成卡住的服务而不进行复制
