Question

我有一个刚用docker swarm init创建的单节点docker群。

我有一个docker-stack.yml，其中包含以下部署：

version: '3.3'

services:

  website:
    image: docker.pkg.github.com/foo/bar/bar:latest
    ports:
      - "80:80"
      - "443:443"
    environment:
      HOST: bar.com
    secrets:
      - site.key
      - site.cert
    networks:
      - foo-net

networks:
  foo-net:
    driver: overlay
    external: true

secrets:
  site.key:
    external: true
  site.cert:
    external: true

首先，我登录到注册表，它告诉我登录成功。其次，我部署堆栈

$ docker stack deploy --with-registry-auth --compose-file docker-stack.yml foo
 Creating service foo_bar

此后，该服务正在运行，并且一切正常。

但是，当我尝试第二次（几秒钟后）使用同一命令部署堆栈时，它失败并显示以下消息。

$ docker stack deploy --with-registry-auth --compose-file docker-stack.yml foo
Updating service foo_website (id: uvtqpdx74784dy9egj5i1c7sb)
image docker.pkg.github.com/foo/bar/bar:latest could not be accessed on a registry to record
its digest. Each node will access docker.pkg.github.com/foo/bar/bar:latest independently,
possibly leading to different nodes running different
versions of the image

为什么会这样？

所有网络和秘密都是预先创建的，我的docker版本是：

$ docker version
Client:
 Version:           19.03.6
 API version:       1.40

感谢您的帮助！谢谢
