You might want to be careful with this though because if your application is built on the same server where your productive apps consuming some of the memory it could affect performance of your deployment or even take it down.
Dokku allows for deploying apps from images built in CI - which is quite effective if you also test your image artifacts in CI and don't want to build twice.
If you are using our Nomad or Kubernetes plugins, you can also run the apps on servers other than the one you are building on.
Right, obviously heat is an enemy of li-ion batteries. My understanding (and I could be wrong) is that if a MBP is plugged in the power bypasses the battery once it reaches 100% charge, correct?
That is my understanding as well. Most of my macbooks (I've owned 3) have been plugged in the majority of the time, with at least some time every few days spent on battery power unplugged. I'd say you're fine as long as you're using the battery at least once every 2-3 weeks -- longer than that might not be good for the battery over long periods of time.
