Importing an image

To get a local copy of the image, we either need to pull it from the accessible registry or import it from the already exported image, as we saw in an earlier recipe. The docker image import command lets you import one or more images from a tarball. The docker image import command syntax is as follows:

docker image import [OPTIONS] file|URL|- [REPOSITORY[:TAG]]

Getting ready

Before you begin, you need a local copy of the exported Docker image.

 

 

How to do it...

Perform the following steps:

1. Transfer the myapache2.tar file we created in the previous recipe to a new Docker host using any of your favorite file transfer tools.
2. Now, on the new Docker host, import the transferred myapache2.tar file, as shown in the following code:

      $ docker image import myapache2.tar apache2:imported

3. Here, we have imported our myapache2.tar file as an apache2:imported image.

There's more...

You can also import TAR files stored in a remote location by specifying their URL.
