According to documentation:
Service create has a –replicas option to define the number of tasks.
Using service update –replicas option, it’s possible to change the number of tasks.
Then, why does it service scale (as I’m a newbie, i can’t post more that 2 links…) exists?
It’s just a short alias? If so, shouldn’t it be stated in docs?
Otherwise, if it part of old swarm (ie: not swarm mode released with 1.12), shouldn’t it be clearly stated on docs?
Or something else and I’m totally confused?
