Most of your images will be created on top of a base image from the Docker Hub registry. Docker Hub contains many pre-built images that you can pull and try without needing to define and configure your own. To download a particular image, or set of images i.

To set these environment variables on a host using systemd , refer to the control and configure Docker with systemd for variables configuration. By default the Docker daemon will pull three layers of an image at a time. If you are on a low bandwidth connection this may cause timeout issues and you may want to lower this via the --max-concurrent-downloads daemon option.

See the daemon documentation for more details. If no tag is provided, Docker Engine uses the :latest tag as a default. This command pulls the debian:latest image:.

Docker images can consist of multiple layers. In the example above, the image consists of two layers; fdd5df33 and a3ed95caeb Layers can be reused by images. For example, the debian:jessie image shares both layers with debian:latest. Pulling the debian:jessie image therefore only pulls its metadata, but not its layers, because all layers are already present locally:.

To see which images are present locally, use the docker images command:. In the example above, debian:jessie and debian:latest have the same image ID because they are actually the same image tagged with different names.

Because they are the same image, their layers are stored only once and do not consume extra disk space. For more information about images, layers, and the content-addressable store, refer to understand images, containers, and storage drivers.

Using names and tags is a convenient way to work with images. When using tags, you can docker pull an image again to make sure you have the most up-to-date version of that image. For example, docker pull ubuntu Docker enables you to pull an image by its digest. When pulling an image by digest, you specify exactly which version of an image to pull. To know the digest of an image, pull the image first. Docker prints the digest of the image after the pull has finished.

In the example above, the digest of the image is:. Docker also prints the digest of an image when pushing to a registry. This may be useful if you want to pin to a version of the image you just pushed. A digest takes the place of the tag when pulling an image, for example, to pull the above image by digest, run the following command:. Docker will therefore not pull updated versions of an image, which may include security updates.

If you want to pull an updated image, you need to change the digest accordingly. By default, docker pull pulls images from Docker Hub. It is also possible to manually specify the path of a registry to pull from. For example, if you have set up a local registry, you can specify its path to pull from it. Registry credentials are managed by docker login. Refer to the insecure registries section for more information. By default, docker pull pulls a single image from the registry. A repository can contain multiple images.

To pull all images from a repository, provide the -a or --all-tags option when using docker pull. After the pull has completed use the docker images command to see the images that were pulled.

The example below shows all the fedora images that are present locally:. Killing the docker pull process, for example by pressing CTRL-c while it is running in a terminal, will terminate the pull operation. The Engine terminates a pull operation when the connection between the Docker Engine daemon and the Docker Engine client initiating the pull is lost. If the connection with the Engine daemon is lost for other reasons than a manual interaction, the pull is also aborted. Status: Downloaded newer image for fedora.
