I installed Docker 1.13 on macOS 10.10, logged in the docker 'machine' with screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty And did a df -h. It says I have a /dev/sda1 mounted on /var/lib/docker/overlay2 with 64 GB of disk space. /dev/sda1 62.7G 5.6G 54.0G 9% /var/lib/docker/overlay2 I had a few builds failing for 'no space left on device' so I suspect this is where all images end up going. What is not clear to me is the following: • what is this /dev/sda1. Is it a virtual image disk somewhere on my mac? If so, where?
• Suppose I am running out of space and I want to store more images. How does one increase this disk space? Daniel's answer is right but I found an easier solution. In my case, I think I did migrate from docker-toolbox back in the days which locked by database to ~17G. I found it easier to follow these instructions: Note that this will delete your containers: • Stop docker for mac • rm ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2 • Start docker for mac It seemed to work on my side.
Mentions and commands that let you backup your containers before nuking your Docker.qcow2. I didn't use them since I didn't really care about my containers.

About images, containers, and storage drivers Estimated reading time: 15 minutes To use storage drivers effectively, you must understand how Docker builds and stores images. Then, you need an understanding of how these images are used by containers. Finally, you’ll need a short introduction to the technologies that enable both images and container operations. Understanding how Docker manages the data within your images and containers will help you understand the best way to design your containers and Dockerize your applications, and avoid performance problems along the way.

Each layer except the very last one is read-only.

Copy Docker Images & Containers To New Mac 015 Sep 7, 2016. The first method you would come up with might be to create a Docker image, push it to Docker Hub, and then pull that image on your new PC. But this requires a great amount of data transfer. What you need to do is to copy the disk.vmdk to the new docker-machine directory. Docker for Mac uses a new file system created by Docker called “osxfs.” I can’t find much detail on the new file system, but there is some information here. You can add or remove share local paths to share with containers using the + and – buttons, but these paths shouldn’t overlap ( e.g., not Users and Users/homefolder ). The default Docker for Mac file performance can be bad. Here are some small tips to improve disk I/O for Docker for Mac. Follow these small steps to get a better disk performance in Docker for Mac.
Consider the following Dockerfile. Shure update utility for mac 10.9.5. FROM ubuntu: 15. / app RUN make / app CMD python / app/ app.
Py This Dockerfile contains four commands, each of which creates a layer. The FROM statement starts out by creating a layer from the ubuntu:15.04 image. The COPY command adds some files from your Docker client’s current directory. The RUN command builds your application using the make command. Finally, the last layer specifies what command to run within the container. Each layer is only a set of differences from the layer before it. The layers are stacked on top of each other.
When you create a new container, you add a new writable layer on top of the underlying layers. This layer is often called the “container layer”. All changes made to the running container, such as writing new files, modifying existing files, and deleting files, are written to this thin writable container layer. The diagram below shows a container based on the Ubuntu 15.04 image. A storage driver handles the details about the way these layers interact with each other. Different storage drivers are available, which have advantages and disadvantages in different situations. Container and layers The major difference between a container and an image is the top writable layer.
