@megastef would you like me to hammer again with 60,000 containers?
Could you explain to me what "active" mode means? Why was agent removed from masters ..
to prevent managers to go berserk, the document recommends that we should put managers into the Drain mode.
The drain mode is "docker node update --availability drain mg0"
with this all containers will be gradually remove from the mode until the node "drained"
This "Drain" mode won't work for our global-service agent.
That's what we have to set the manager to be "Active" first, which is the default mode.
The problem is that when the manager goes down, the agent is gone. And because the manager is "Paused", the agent will so disappear.
This is our discovery today :-)
I can't take too much credit @demonware have been great in supporting docker projects over the past 3 years
any tweets, mentions are appreciated ;)
can we @tomwillfixit_twitter

I'd like to shut the nodes down around 5pm if we are done for the day?
