The `URL` can point to an archive (.tar, .tar.gz, .tgz, .bzip, .tar.xz, or .txz) containing a filesystem or to an individual file on the Docker host. If you specify an archive, Docker untars it in the container relative to the `/` (root). If you specify an individual file, you must specify the full path within the host. To import from a remote location, specify a `URI` that begins with the `http://` or `https://` protocol. The `--change` option will apply `Dockerfile` instructions to the image that is created. Supported `Dockerfile` instructions: `CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR` ## Examples **Import from a remote location:** This will create a new untagged image. $ docker import http://example.com/exampleimage.tgz **Import from a local file:** Import to docker via pipe and `STDIN`. $ cat exampleimage.tgz | docker import - exampleimagelocal:new Import with a commit message. $ cat exampleimage.tgz | docker import --message "New image imported from tarball" - exampleimagelocal:new Import to docker from a local archive. $ docker import /path/to/exampleimage.tgz **Import from a local directory:** $ sudo tar -c . | docker import - exampleimagedir **Import from a local directory with new configurations:** $ sudo tar -c . | docker import --change "ENV DEBUG true" - exampleimagedir Note the `sudo` in this example – you must preserve the ownership of the files (especially root ownership) during the archiving with tar. If you are not root (or the sudo command) when you tar, then the ownerships might not get preserved.
