What is Docker in Docker?

Although running Docker inside Docker is generally not recommended, there are some legitimate use cases, such as development of Docker itself.

Docker is an open-source project that automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization on Linux, Mac OS and Windows.

Before running Docker-in-Docker, be sure to read through Jérôme Petazzoni’s excellent blog post on the subject, where he outlines some of the pros and cons of doing so (and some nasty gotchas you might run into).

If you are still convinced that you need Docker-in-Docker and not just access to a container’s host Docker server, then read on.

How to use this image

Start a daemon instance

IMPORTANT: this image defaults to --storage-driver=vfs, which will be very slow and inefficient (but is the only driver which is guaranteed to work regardless of your underlying filesystem). Which driver you should use varies depending on your needs, but a good rule of thumb is that your DinD instance should be using the same driver as your host (which can be seen under Storage Driver in the output of docker info). See the Custom daemon flags section below for how to specify your storage driver.

        $ docker run --privileged --name some-docker -d docker:1.8-dind


--privileged is required for Docker-in-Docker to function properly, but it should be used with care as it provides full access to the host environment, as explained in the relevant section of the Docker documentation.

This image includes EXPOSE 2375 (the Docker port), so standard container linking will make it automatically available to the linked containers (as the following examples illustrate).

Where to Store Data

Important note: There are several ways to store data used by applications that run in Docker containers. We encourage users of the docker images to familiarize themselves with the options available, including:

  • Let Docker manage the storage of your data by writing to disk on the host system using its own internal volume management. This is the default and is easy and fairly transparent to the user. The downside is that the files may be hard to locate for tools and applications that run directly on the host system, i.e. outside containers.
  • Create a data directory on the host system (outside the container) and mount this to a directory visible from inside the container. This places the files in a known location on the host system, and makes it easy for tools and applications on the host system to access the files. The downside is that the user needs to make sure that the directory exists, and that e.g. directory permissions and other security mechanisms on the host system are set up correctly.

The Docker documentation is a good starting point for understanding the different storage options and variations, and there are multiple blogs and forum postings that discuss and give advice in this area. We will simply show the basic procedure here for the latter option above:

  1. Create a data directory on a suitable volume on your host system, e.g. /my/own/var-lib-docker.
  2. Start your docker container like this:

                    $ docker run --privileged --name some-docker -v /my/own/var-lib-docker:/var/lib/docker -d docker:dind

The -v /my/own/var-lib-docker:/var/lib/docker part of the command mounts the /my/own/var-lib-docker directory from the underlying host system as /var/lib/docker inside the container, where Docker by default will write its data files.
