我正在使用Docker 18.05和Docker Swarm来部署具有滚动更新的多个任务的服务。有时，3个任务中有1个没有使用最新版本进行更新。 阅读完这个问题后，我在docker compose文件中添加了标记，以确保它能够提取最新的图像。我也转移到Amazon ECR而不是本地注册表，但它没有解决问题。
这是一个抽象的问题，但我不知道如何解决它。 此外，是否有任何部署日志可以帮助我了解已收到更新的任务？
部署代码：
sudo docker-compose build
sudo docker-compose push
sudo docker stack deploy --compose-file docker-compose.yml --prune --resolve-image always --with-registry-auth my_stack

更新：
我删除了重启和重启策略，但没有解决问题。
我也尝试将order: start-first添加到配置中它确实解决了问题，但由于某种原因，我在第二个容器更新时有1秒的停机时间。
