为什么docker stack deploy找不到本地镜像？

Question

这有时工作正常，但有时 docker swarm 无法获取 docker 图像。哪个是本地构建的，这里可能是什么问题？我使用了 --with-registery-auth 也没有用。

请看下面的屏幕截图，其中明确说明我的本地图像可用。

下面是我的docker-compose.yml

version: "3.8"
services:
  mongodb:
    image: mongo
    environment:
      MONGO_USER: reddituser
      MONGO_PASS: redditpass
      MONGO_DB: reddit-demo
    deploy:
      placement:
        constraints:
          - node.role == manager
    ports: 
      - "27017:27017"
    networks:
      - reddit
    volumes:
      - ./init-mongo.js:/docker-entrypoint-initdb.d/init-mongo.js
      - mongodb:/data/mongodb
  redisdb:
    image: redis
    volumes:
      - redis:/data/
    ports:
      - "6379"
    networks:
      - reddit
  app:
    image: hapi-backend
    ports: 
      - "3000:3000"
    environment:
      MONGO_HOST: mongodb
      MONGO_PORT: "27017"
      MONGO_DB: reddit-demo
      MONGO_USER: reddituser
      MONGO_PASS: redditpass
      REDIS_HOST: redisdb
      REDIS_PORT: "6379"
    networks:

因为您在本地主机上使用注册表：

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

在您的 swarm 上将注册表作为服务启动
使用docker service ls
检查其状态
检查它是否与 curl
一起工作
