我们在DMZ中的RHEL 8.1上运行的Docker Swarm Cluster（社区版）中有3名经理和3名工人。我们也有类似的喜欢在非产品环境中设置的类似，当我们将基础VM修补为最新的RHEL 8.X版本时，我们没有问题，包括Docker版本升级到最新版本。
但是，每当我们尝试修补生产群集VM时，即使表面上的群体恢复正常，我们看到所有的服务和任务都在运行，但是出于某种奇怪的原因，Docker Swarm会散发Docker Ingress Ingress Load Placeancation Falancation能力。我们已经尝试升级几种不同的方式和多次，但是每次我们最终取得相同的结果时，我们都必须恢复。
任何人都可以阐明一些地方，为什么会发生这种情况？
提前致谢，
We have a set of 3 managers and 3 workers in a docker swarm cluster (community edition) running on RHEL 8.1 in a DMZ. We have a similar like to like set up in a non prod environment where we don't have issues when we patch the underlying VMs to latest RHEL 8.x versions including the docker version upgrade to the latest versions.
But any time we try patching the production cluster VMs, even though the swarm on the surface comes back up fine and we see all the services and tasks running, but for some weird reason the docker swarm looses the docker ingress load balancing capability. We have tried upgrading several different ways and many times, but every time we end up with same result and we have had to revert.
Can any one please shed some light into where to look and why this could be happening ?
Thanks in advance,
