Question

目前我在docker swarm工作，我在裸机服务器上制作了带有docker swarm的2节点集群。我试图在每个节点中运行单个容器，它们正在运行。但是当我写docker-compose.yml文件来运行副本时。它会出错，我的 docker-compose.yml 就在这里。

version: "3"
services:
  web:
    # replace username/repo:tag with your name and image details
    image: brainplow/shopnroar:latest
    deploy:
      replicas: 2
      restart_policy:
        condition: on-failure
      resources:

          memory: 50M
    ports:

当我运行docker service ls时，它会提供以下内容，

当我运行docker service ps igz1ceqtawkk

时

它给了我这个错误，

有时这个

任何人都可以告诉我它为什么会发生。

和

任何人都可以告诉我为什么我的容器没有在服务中运行。我坚持下去了。

提前致谢。真的需要帮助。

Answer 1

问题现在解决了。这是由于核心版本。我正在研究裸机云，我在上面安装了Ubuntu 16.04。但我忘了安装这个版本附带的核心。

用自己的内核重新安装Ubuntu之后，问题就解决了。
