为什么 docker stack deploy 找不到本地镜像？

Question

这有时可以正常工作，但有时 docker swarm 无法获取 docker 映像。哪个已在本地构建，这可能是什么问题？我用了--with-registery-auth，也没有用。

请看下面的截图，上面清楚地说明了我的本地图片可用。

下面是我的docker-compose.yml

  mongodb:
    image: mongo
    environment:
      MONGO_USER: reddituser
      MONGO_PASS: redditpass

    deploy:

        constraints:

Answer 1

因为你在 localhost 上使用注册表：

所以看看：https://docs.docker.com/engine/swarm/stack-deploy/#set-up-a-docker-registry

1. 在您的 swarm 上将注册表作为服务启动

2. 通过docker service ls检查其状态

3. 检查它是否与curl一起工作
