Just my 2 cents regarding this: I've already stopped using Docker directly on my MBP15 (2017, 2.8GHz i7). It reserves a huge chunk of disk and RAM. Running anything non-trivial (e.g. k3d and a few pods) led to a very noticeable slowdown. My fan was noisy all day. Instead I purchased (for a very, very modest amount of money) a decommissioned rack server with a dual Xeons (2*8=16C/32T) and 64GB of DDR3 RAM. It's on my local gigabit network. I docker-machine into it. The hardware is obviously older but build times are in the same ballpark. I'm holding out for the 16" ARM MacBook Pro but I'll probably pull the trigger when it's released.
