Used the docker update command, but because of host mode, we are getting port conflicts. Can’t you use ingress mode, as it needs extensive setup with traffic routing and nginx. Are there any other ways which I can try
I tried to use the Docker service update command, but got errors because of Port conflicts and cause of host mode. Can’t really use ingress mode as it will take extensive setup as a Load balancer and reverse proxy setup
Regarding Zero downtime, it is not clear what your setup is, how many workers you have, and I’m not a Swarm user (I use Kubernetes), so I don’t remember how scheduling works exactly in Docker Swarm, but in general, you will not have zero downtime on a single node or if yo can’t make sure your new instance is started on a new node, when you are using the host mode
