The crash looked like a process killed by the OOM killer, but since the setup worked fine in docker-compose mode, I did not immediately suspect memory problems. I was hit by a python command reporting a database crash, after switching from docker-compose to docker swarm mode. In the latter case, you might need to give HyperKit more or less memory, depending on your actual usage. If you see that it runs to its maximum, check in the hyperkit itself the memory usage is linux filesystem buffers, or real application usage. HyperKitвЂ™s memory itself can be monitored by the MacвЂ™s Activity Monitor. Finding the right memory setting for HyperKit The hyperkit vm will not consume that much memory if you do not use it. Here you will be able to change the amount of memory. Enter the HyperKit VM to watch memory usage of the docker hostД®nter this command and press вЂenterвЂ™ to enter the HyperKit VM screen ~/Library/Containers//Data/64-linux/ttyД¬lick the docker symbol in the menu bar, and select вЂPreferencesвЂ™ from the docker menu.

Long story short, here is how to watch memory usage, and increase it if necessary. The overall experience with the default configuration feels so much like running docker on linux, that youвЂ™d almost forget that the docker containers are running in their own VM, with its own disks, cpu and memory settings. I am running the Docker CE version 17.09 on a Mac.
