I have a full infrastructure with Docker swarm multiple nodes and horizontal scalability.
I use docker service update to deploy new version of my application without interruption.
I'm now working on a chatbot to deploy my application from Slack, is there a way to follow the progress of the update? I didn't see any events or webhooks to manage that
It is very scary to launch service update without any info / output
In docker 17.05, a new option --detach, -d is introduced to docker service create and update.
There isn't much documentation yet, as usual. You can check the pull. And there is a slightly out of date demo.
This is what I got on 17.05.
