docker-compose.yml 这是我的 docker-compose 文件，用于使用 docker-stack 在多个实例中部署服务。如您所见，应用程序服务是在 2 个节点中运行的 laravel 和在其中一个节点中运行的数据库（mysql）。

完整代码库： https ://github.com/taragurung/Ci-CD-docker-swarm 

version: '3.4'
networks:
  smstake:   
    ipam:
      config:
        - subnet: 10.0.10.0/24

services:
    db:
        image: mysql:5.7
        networks:
          - smstake
        ports:
          - "3306"
        env_file:
          - configuration.env
        environment:
          MYSQL_ROOT_PASSWORD: ${DB_ROOT_PASSWORD}
          MYSQL_DATABASE: ${DB_NAME}
          MYSQL_USER: ${DB_USER}
          MYSQL_PASSWORD: ${DB_PASSWORD}
        volumes:
          - mysql_data:/var/lib/mysql
        deploy:
          mode: replicated
          replicas: 1

    app:
        image: SMSTAKE_VERSION
        ports:
          - 8000:80
        networks:
          - smstake
        depends_on:
          - db
        deploy:
          mode: replicated
          replicas: 2

我面临的问题。 1. 虽然在查看服务日志时服务处于运行状态，但我只能看到迁移在一个节点上成功，而在另一个节点上没有运行。请参阅下面的日志

  1. 当我使应用程序服务仅在管理器节点中运行时，应用程序运行得很好。我可以登录页面并执行所有操作，但是当我仅使用副本使应用程序服务在任何节点中运行时，登录页面就会显示，但是当尝试登录时，它会重定向到 NOT FOUND 页面

这是尝试在 3 个节点上运行时的完整日志。Bellow 是在 2 个节点上运行时的示例。您可以详细查看迁移问题 https://pastebin.com/wqjxSnv2

使用检查的服务日志docker service logs <smstake_app>

不知道是移民问题还是什么。有时我可以登录，但在单击仪表板内的链接时，我再次被重定向到未找到页面。

因此，我运行了您的服务并发现了一些问题。

  • mysql中的用户docker-compose.yml不同。这可能只是为了发布目的
  • 在您的Dockerfile中，您使用了ENTRYPOINT它导致相同的命令也在迁移服务上运行。我把它改成 CMD
  • 您没有migration在与 mysql 数据库相同的网络中运行该服务。所以mysql不能从同一个地方到达。

这是我使用的最终撰写文件

WORKDIR /apps

RUN chmod -R 775 storage

然后再次运行服务。然后迁移顺利
