When you navigate to ~/Library/Containers you will see the folder name Docker instead. This directory is easy to get to from the terminal, but if you try to get there via the finder you might notice that does not appear visually under that directory name. On a mac our docker files are located inside of a virtual machine which is located in our user library directory: ~/Library/Containers//

Here is a little background information on the docker directory Docker Desktop - Mac is the fastest and most reliable way to run Docker on a Mac.

Docker Desktop for Mac is a complete development environment deeply integrated with the Mac OS Hypervisor framework, networking, and filesystem. Try option 1 first, if it does not work try option 2 Docker Desktop for Mac is an easy-to-install desktop app for building, debugging, and testing Dockerized apps on a Mac. There are two primary ways to get to this directory. You see that command will tell you that the root directory is located at /var/lib/docker, which on a mac is a non-existent directory. Usually on most systems, you can see where the images and containers are located by running the command docker info but no, that does not work on a mac. See DTrace Action Basics for some more details.Finding the location of docker images is a chore on a mac. Ustack() is a bit slower - to emit the actual function names, dTrace has to do a lot more work to get them from the address spaces of the appropriate processes.Дisabling System Integrity Protection might help you get better stack traces. userspacehotspots.d > /tmp/userspace_hot_spots.txt This is a small dTrace script I use to find where the kernel is spending its time (it's from Solaris, and dates back to the early days of Solaris 10): #!/usr/sbin/dtrace -s profile:::profile-1001hz /arg0/ restarting containers, or running lots of healthchecks), then you can debug that by watching the output of: docker events

If the docker engine itself is thrashing (e.g. And the IO numbers shown in pidstat align roughly with what you see written to the qcow2 image. The instantaneous usage is over 12% from top, not 3%, since you need to add the system and user percentages. Inside the VM there's over 100% load shown in the top command for the average in the past minute (though less from the 5 and 15 averages) which is roughly what you see for the hyperkit process on the host.

A 4 core MBP has 8 threads, so full CPU utilization should be 800% if MacOS is reporting the same as other Unix based systems. You can then -d to destroy the alpine container.ДЇrom the comments and edits, these stats may check out. The stats are every 5 seconds for one minute (12 times) and then it will give you an average table per process.

Download and install Docker Desktop for Mac.After the installation is complete, the Docker icon will be displayed in the menu bar. That will run inside the alpine container running in the VM pid namespace, showing any IO happening from any process, whether or not that process is inside of a container. Docker Desktop for Mac If you are running macOS 10.10.3 (Yosemite) or later, follow these instructions to install Docker Desktop for Mac.

To track down if it's IO, you can also try the following: $ docker run -it -rm -pid host alpine /bin/sh $ apk add sysstat $ pidstat -d 5 12 You can also try the following command to debug any process issues within the embedded VM that docker uses: docker run -it -rm -pid host busybox top However, if your image contains a large number of small files, performance will suffer, especially if you also have lots of image layers. Mainly, if you can accept fewer consistency checks, you can set the volume mode to delegated for faster performance. With MacOS volumes, this involves osxfs where there is some performance tuning you can perform. My suspicion is that the issue is IO related.
